    Stress Relieving Capabilities

    As one of the most widely used manufacturing materials in various industries, steel often encounters processes like welding, machining, and cold working. These techniques introduce internal stresses to the metal. If left unchecked, they can lead to several issues, including distortion and cracking. The solution? Stress relieving — a heat treatment process that enhances steel’s stability and strength.

    When steel is heated within a specific temperature range — usually below its lower critical temperature — its crystal lattice changes. Holding the steel at this temperature allows time to redistribute stresses, effectively realigning the structure. Then, slow and controlled cooling locks in the newly achieved stress-free equilibrium. This results in a more balanced, uniform microstructure less prone to distortion, cracking, and other structural anomalies.

    This blog will discuss the benefits of stress relieving and the factors to consider when using this technique.

    Benefits of Stress Relieving

    Stress relieving steel is a critical step in metal manufacturing and processing, offering numerous benefits:

    Enhanced Dimensional Stability

    Stress relieving enhances steel’s size and shape consistency by minimizing the changes that occur during manufacturing processes like welding or machining. By carefully heating the material within specific temperature ranges and timeframes, stress-relieved steel maintains its intended dimensions and becomes less prone to distortion.

    Elevated Mechanical Properties

    Steel that has undergone stress relieving exhibits improved mechanical properties. By releasing internal defects and refining the crystal lattice structure, stress relieving enhances the steel’s toughness, ductility, and overall strength.

    Minimized Risk of Early Failure

    Residual stresses are a ticking time bomb within steel structures. Stress relieving defuses this bomb by reducing internal stresses, making steel less prone to unexpected failures and cracks.

    Optimized Machinability

    By minimizing internal stresses, the steel becomes more responsive to tools, resulting in enhanced ductility and machining flexibility. This optimizes the manufacturing process, contributing to a component’s prolonged lifespan.

    5 Factors To Consider in Stress Relieving

    When performing stress relieving, several factors should be considered:

    1. Material Composition

    The chemical composition of the steel significantly influences its behavior during stress relieving. Different alloying elements can affect the steel’s transformation temperatures, phase changes, and mechanical properties.

    2. Processing History

    The manufacturing history of steel before stress relieving plays a crucial role. The extent of these prior processes affects the overall strategy. For instance, heavily cold-worked steel may require longer stress-relieving times to ensure complete stress reduction.

    3. Temperature

    The temperature range for stress relieving is critical. Too low, and the desired stress reduction won’t occur; too high, and the steel’s properties might change significantly. Experts use a combination of phase diagrams, empirical data, and experience to pinpoint the optimal temperature range.

    4. Duration

    Holding the steel at the chosen temperature is equally important. The duration depends on factors like the thickness of the material, its composition, and the extent of prior processing. Longer times may lead to better stress relaxation, but overexposure may alter some of the material’s properties.

    5. Cooling Considerations

    The cooling phase of stress relieving must also be controlled. Rapid cooling can reintroduce stresses, negating the benefits of the process. On the other hand, controlled cooling ensures that the redistributed stresses are locked in a balanced state.

  6. Surface Grinding

    Leave a Comment

    Surface Grinding

    Surface grinding is a machining procedure to smooth and finish a workpiece’s flat surfaces. It uses a rotating abrasive wheel that produces a precise and smooth finish. This technique is commonly employed in manufacturing industries to achieve tight tolerances and improve the surface quality of metal, plastic, or other substances.

    In this article, we will explore the fundamentals of this grinding method, including its operating principles and various types.

    How Surface Grinding Works

    Surface grinding utilizes a grinding wheel, a tool with abrasive particles that are adhered to its surface and rotates at high speeds. The workpiece, or processed material, is placed on a magnetic chuck or held down by other means. The wheel spins across the surface, cutting tiny shards with each pass. The abrasive granules also remove particles through cutting, plowing, and rubbing.

    The grinding process is carefully controlled to achieve the desired outcome. The rotational speed, depth of cut, and feed rate are regulated to maximize material removal while preventing excessive heat buildup. Coolants are also frequently used to dissipate heat and prolong the life of the machine components. As the process continues, the workpiece’s surface gradually becomes smoother and more uniform.

    At Nifty Bar, we employ a 30” x 120” table to accommodate various workpieces, effectively processing larger materials. This sizable table provides enough room to secure the piece, which ensures stability and accuracy throughout the grinding process. Additionally, it guarantees that the final products meet exact specifications.

    Types of Surface Grinding

    The following methods have their strengths, allowing manufacturers to choose the best technique based on the workpiece material, size, shape, and required finish:

    Creep Feed Grinding

    Creep feed grinding is distinguished by its deliberate use of slow speeds and deep cuts, allowing it to precisely shape intricate geometries. It minimizes heat generation and prevents workpiece deformation by gradually removing material in layers. This technique is especially valuable when working with elements that are difficult to machine using traditional methods.

    Form Grinding

    Form grinding relies on specialized grinding wheels that are shaped to replicate the desired profile. It particularly applies to manufacturing components with complex geometries that necessitate precise dimensional accuracy. In addition, it is crucial in the aerospace and medical industries, where items feature intricate designs that demand impeccable precision and surface finish.

    Peripheral Grinding

    Peripheral grinding is a technique that uses the grinding wheel’s outer edge to smooth and shape the surface. Its material removal efficiency is particularly noteworthy, as it can quickly clear many particles, speeding up the manufacturing process. This procedure is commonly used to achieve flat finishes, making it suitable for producing parallel faces on metals.

    Plunge Grinding

    Plunge grinding is differentiated by the direct insertion of the grinding wheel into the workpiece, resulting in a more aggressive material removal. This method is widely used to create surface grooves, recesses, and other complex patterns. Plunge grinding also enables the production of precisely sized components by adjusting the depth of cut and the feed rate.

    Rotary Grinding

    Also called Blanchard grinding, rotary grinding is a unique approach that involves a fixed grinding wheel and a rotating magnetic chuck. It allows for rapid material removal by keeping the wheel stationary and spinning the piece. This configuration is intended to efficiently remove material from large and heavy workpieces.

  8. The Basics of Double Disc Grinding

    Leave a Comment

    The Basics of Double Disc Grinding

    Double Disc grinding simultaneously grinds two sides of material using two opposing abrasive wheels. It is a very effective grinding technique for obtaining surface smoothness, flatness, and parallelism with tight tolerances in the appropriate applications.

    This grinding technique can remove more material, cutting the grinding time in half. Additionally, this method can efficiently process various materials — including stainless steel, tool steels, sintered metals, high-strength alloys, ferrous or non-ferrous metals, bronze, copper, aluminum, and more.

    What Is Double Disc Grinding?

    Double Disc grinding is typically employed for high-productivity manufacturing requirements. However, many factors may affect the output rates, including the size, material, stock removal,starting flatness, and tooling arrangement. Depending on these factors, outputs can be as high as 40,000 parts per hour or just a few pieces.

    This technique is very effective and can cut pre-machining costs by as much as 50% since the material is removed from both sides in equal amounts in a single operation. It is ideal for requirements under the following conditions:

    • The parts have equal surface area requirements on opposing surfaces.
    • The size of the component required is close to the size of the grinding wheels.
    • The length, diameter, and overall width should be within tight tolerances.
    • The part’s thickness should be related to the opposing face to be processed.

    Advantages of Double Disc Grinding

    Depending upon the material and start flatness high dimensional accuracy can be obtained via Double Disc grinding, with tolerances, parallelism, and flatness down to 0.0005 inches (0.0127 mm). Controlling the thickness of small metal pieces using it is also economical.

    Double Disc grinding can also improve your parts manufacturing processes in the following ways:

    Reduced Machine Cost

    Because the grinding wheels degrade throughout the conventional grinding process, they occasionally need to be changed or redressed. On the other hand, double disc grinding lowers the wear rate, resulting in fewer grinding process redressing stops.

    High Degree of Accuracy

    The ability to simultaneously grind both sides of the workpiece gives operators more control, allowing them to achieve tighter tolerances for flatness and parallelism checks. Additionally, when grinding aluminum, the method may produce surface polishes as high as 16 Ra and dimensional tolerances of 0.0005 in. Flatness tests can also achieve the same degree of precision.

    Internal Stress Relief

    Double Disc grinding lessens the workpiece’s residual load due to how it operates. During secondary operations and final machining, stability is improved when residual stress is decreased.

    Better Surface Finishes

    This technique can attain flatness tolerances that would be extremely challenging to achieve using a single-sided grinding procedure. In addition, Double Disc grinding generates a better surface polish than many other grinding procedures by lowering or removing grind patterns as pieces depart.

    Double Disc Grinding With Nifty Bar

    Materials processed through double disc grinding can be used to manufacture several products and applications, including the following:

    • Knives, handles, and clips
    • Component part blanks

  9. Double-Disc Grinding vs. Flat Lapping

    Leave a Comment

    Double-Disc Grinding vs. Flat Lapping

    Double-Disc Grinding and Flat Lapping are cost-effective machining processes for components requiring size control or a fine or specific surface finish. Although these methods have identical purposes, their operations, advantages, and disadvantages vary.

    Nifty Bar offers Grinding, Cutting, Milling, and Finishing services for parts, tooling, dies and molds, pre-machined blanks, fixtures, and signages used in various industries. Further, our capabilities allow us to deliver Double-Disc Grinding services that satisfy our client’s need for excellent dimensional control.

    This article will discuss the differences between double-disc grinding and flat lapping and assess the best option for various applications.

    What Is Double-Disc Grinding?

    Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind both sides of a component. The wheels are side-mounted on a pair of spindles facing each other, and — because both sides of the workpiece are ground at the same time — fabricators achieve faster turnaround time. This method can also achieve tight-tolerance surface finishes, flatness, and parallelism in suitable applications.

    This method is often classified into two machine types — horizontal and vertical double-disc grinder — based on how the grinding wheels are oriented and how parts cross through them. A double-disc grinder is horizontal if the wheels are paralleled to the floor and vertical if they are perpendicular.

    The product of this grinding technique are flat plates with finishes to 16 Ra and parallel tolerances to .0005″, depending upon material type, size and stock removal.

    Applications of Double-Disc Grinding

    The most common applications for Double-Disc grinding are as follows:

    • Rotor finishing
    • Connecting rods
    • Hydraulic pump components
    • Orthopedic skeletal implant plates.
    • Aerospace components
    • Knives, Blades & Handles
    • Nontraditional components (glass, plastic, graphite, ceramic)

    Advantages and Disadvantages of Double-Disc Grinding

    Double-Disc grinding ability is to extract equal parts of material from opposite sides of a workpiece that results in applying a reduced amount of internal stress to the materials. Furthermore, it enhances stability during machining operations, leading to higher accuracy and parallelism. Moreover, up to 50% of pre-machining costs are saved since this technique can achieve flatness tolerance faster than single-sided grinding.

    On the other hand, Double-Disc Grinding fails to produce surface finishes as smooth as flat lapping. The latter grinding process is often used to correct irregularities or deterioration on the surface of metal parts.

    What Is Flat Lapping?

    Flat lapping is a mechanical sanding or polishing procedure where an abrasive is placed between two surfaces that are honed together. This process often results in a more accurate surface finish for elements and compounds like cast iron, ceramics, tungsten, plastics, carbon compounds, stainless steel, bronze, rubber, and silicon.

    Applications of Flat Lapping

    Flat lapping utilizes abrasive grains mixed with either oil- or water-based liquid vehicles to achieve a smooth surface. This method is typically used in the following applications:

    • Hard and brittle metals
    • Machining materials (e.g., glass)
    • Valve manufacturing
    • Polishing operations (automotive industries)

    Advantages and Disadvantages of Flat Lapping

    Due to the less complex machining process, flat lapping doesn’t require skilled laborers to complete the procedure, increasing its production rate. This technique also removes burrs on materials to achieve a high surface finish without generating heat.

    However, flat lapping is generally slower than double-disc grinding, as only one side of the workpiece is furnished for each cycle. Additionally, it is not as pocket-friendly because it can only remove a minimal amount of stock on the material, and the surface finish needs to be uniform.

    Why Choose Nifty Bar

    Double-Disc Grinding offers more advantages to consumers than flat lapping. Not only is the former a more practical alternative, but fabricators can achieve a faster turnaround time than the latter.

    Waterjet cutting COould be used for a variety of other materials. These include, but are not limited to:

    • Metals such as aluminum, brass, and steel
    • Non-metallic materials such as glass, plastic, and stone
    • Composite materials such as carbon fiber and Kevlar

    Each type of material has its unique properties that must be considered when choosing the best waterjet cutting method. For example, metals are strong and durable but can be difficult to cut through due to their hardness. Glass is fragile but can be cut with very high precision.

    Waterjet cutting can also be used on composite materials, which are made up of multiple different types of material bonded together. This makes them extremely strong and resistant to damage. However, composite materials can be difficult to cut due to their complex structure.

    When choosing a waterjet cutting method, it is crucial to consider the type of material that will be cut as well as the desired outcome. Waterjet cutting is a versatile technology that can be used on various materials. With proper planning and execution, waterjet cutting can produce precise, high-quality results.

    Types of cuts using waterjet cutting

    Waterjet cutting is a versatile process that can be used to cut various materials. The type of cut made with waterjet cutting depends on the material being cut and the application for which it will be used. Some common types of cuts made with waterjet cutting are:

    • Straight cuts: Straight cuts are the most basic type of cuts made with waterjet cutting. They are typically used for simple applications such as trimming or shaping edges.
    • Contour cuts: Contour cuts are more complex than straight cuts and are used when more precise shapes or patterns need to be cut into a material.
    • Kerf cuts: Kerf cuts are made by directing the jet of water at an angle so that it cuts a V-shaped groove into the material. They are often used for making decorative cuts or for joining two pieces of material together.
    • Pierce cuts: Pierce cuts are made by starting the cut at an edge of the material and then moving the jet of water in a circle to create a hole in the center of the material. They are typically used for applications such as creating holes for fasteners or making openings for pipes or ductwork.

    Understanding the Benefits of Precision Saw Cutting

    In precision saw cutting, a mechanized blade cuts through metal, wood, or plastic workpieces to create smaller components or pieces. Precision cutting is typically used to make components — such as pipes, tubes, and bars to the right dimensions. Unlike other cutting processes like laser cutting or waterjet cutting, saw cutting techniques use a sharp, hard blade to physically cut the material. These blades come in a variety of different styles, such as circular saws, cold saws, or band saws, to accommodate different material thicknesses and specifications. Precision sawing offers a wide range of benefits that make it essential in various fabrication projects.

    Benefits of Precision Saw Cutting

    Precision cutting offers several benefits for both high-volume and low-volume orders. Some of the most common benefits include:

    • Cost-Effectiveness. Precision sawing is a quick, simple process that doesn’t require specialized tooling and results in little to no material waste. Cutting yield loss is also typically covered in the price so there are no surprises.
    • Speed. Both manual and CNC sawing equipment can quickly cut through single workpieces for complex custom goods or large batches of pipes and bars. This ensures that products are ready for subsequent operations when you need them. 
    • Outsourced services allow for lean manufacturing operations. By outsourcing your precision saw cutting services, you can save valuable plant floor space for your specialties rather than setting up bulky sawing equipment.
    • Precision. High-quality sawing processes can cut goods so they meet required specifications within tight tolerances and with minimal waste.
    • Improved cash flow. Outsourced precision sawing services can fit within your timeline so you don’t pay for unused time, which improves operational cash flow.
