Optical projection grinder

Optical projection grinder

Optical Curve Profile Grinder is also called Profile Grinding Machine (PG). It provides a high-quality guarantee for the curve profile grinding of special-shaped precision parts and can get a mirror surface effect. It is suitable for machining hard metal complex components in cemented tungsten carbide or high-speed Speed(HSS) Materials. such as various precision components for micro metal stamping dies and punching tools.

Tolerance range:±0.002

Surface roughness: Ra0.2

Workpiece size: 200*300*300mm

Centerless Grinding Services (OD)

Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. We can perform Centerless Grinding services for the large number of metal parts you may want grinded within a short period of time. Centerless Grinding is definitely the way to go if you have a large number of parts and components that need to be shaped and grinded.

Tolerance range:±0.002

Surface roughness: Ra0.2

Workpiece size: Φ0.8-60*120 mm

Cylindrical Grinding Services (OD & ID)

Cylindrical Grinding Services (OD & ID)

We specialize in precision cylindrical grinding– that is, precision grinding inside diameters (ID) and outside diameters (OD) of cylindrical parts, excelling at those with multiple features, such as grooves, radii, and tapers. Precision ID/OD grinding provides better part-to-part consistency over similar, alternative turning processes, especially for parts with size, roundness, concentricity, and surface finish requirements..

Tolerance range:±0.002

Surface roughness: Ra0.2

Workpiece size: Φ0.8-60*120 mm

Surface Grinding Services

We can accommodate large surface materials. Dimensional tolerances to ±0.002mm can be accomplished. Surface grinding is ideal for materials with a large surface and reducing cost by surface grinding multiple units at the same time. This can be achieved with stringent tolerances.

Tolerance range:±0.002

Surface roughness: Ra0.2

Workpiece size: 250*500*800mm

Finishing Surface Processes

Achieving the desired surface finish and dimensional accuracy is crucial in manufacturing and precision machining. 

Various techniques are used to achieve desired surface finishes, dimensional accuracy, and functional characteristics of multiple components.


Four standard methods for refining surfaces are grinding, honing, lapping, and polishing. 

  • Grinding

    Grinding

    Grinding is primarily employed for removing excess material, reshaping workpieces, and improving surface roughness. Utilizes grinding wheels with abrasive grains that remove material by the cutting action of the grains.
  • Honing

    Honing

    Honing is a precision machining process primarily focusing on improving cylindrical bores, holes’ geometry, and surface texture.

    It is widely utilized in applications where tight tolerances, straightness, and roundness are critical, such as engine cylinders, stators’ internal diameter, hydraulic components, and gear manufacturing.
  • Lapping

    Lapping

    Lapping: Lapping is a process that utilizes a loose abrasive in a suspension or paste form to achieve a high degree of flatness, surface finish, and dimensional accuracy.

    It is often employed to finish flat or spherical surfaces, such as optical lenses, semiconductor wafers, and precision gauges.
  • Polishing

    Polishing

    Polishing is a surface finishing process that enhances a workpiece’s appearance, smoothness, and reflectivity. It involves using progressively finer abrasives and polishing compounds to remove surface imperfections and achieve a glossy finish.

    It is often employed in applications where aesthetics are important, such as optical components.

    • Available Material For Precision Grinding

    Plastic: ABS, PC, ABS+PC, PMMA(Acrylic), PA(Nylon), PA+GF30, POM(Acetal / Delrin), PP, PVC, HDPE, PPS, PEEK, PEI(Ultem), Teflon, Bakelite Resin, Epoxy Tooling Board.
