    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.

    Through-Feed Grinding

    Through-feed grinding is a specialized technique best suited for slender and elongated materials. This method involves feeding the workpiece constantly through the grinding wheels, resulting in consistent debris removal along its length. It finds applications in industries such as automotive and manufacturing, where components like shafts and rods need precise dimensions.

  4. 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
    • Connecting rods
    • Cutters and dies
    • Extrusions
    • Gages
    • Gears and gear blanks
    • Laminations
    • Medical, dental, and orthopedic plates
    • Shims, spacers, and washers

    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.
