Slitting Shims

Precision Slitting Shims Manufacturer | Shim Rings for Metal Slitting Lines

High-Precision Shim Rings for Fine Adjustment of Slitting Tooling

SUZHOU JIN LI (SZJL) Cutting Tools manufactures standard and custom Slitting Shims, also known as Shim Rings, for metal coil slitting lines.

Precision shims are used in the slitting tooling stack for fine adjustment of knife clearance, tooling position and stack dimensions. Accurate shim thickness helps achieve repeatable tooling setups and stable slitting performance.

Our shims can be manufactured for slitting lines processing carbon steel, stainless steel, aluminum, copper, electrical steel and other metal strip materials.

Custom OD, ID, thickness, material, hardness and surface finish are available according to drawings, samples or existing tooling requirements.

FAQ

What are Slitting Shims used for?

Slitting Shims are used for fine adjustment of knife clearance, tooling position and stack dimensions in metal slitting lines.

What is the difference between a Spacer and a Shim?

A Spacer is generally used to establish the required tooling spacing and stack dimensions, while a Shim provides fine adjustment where small dimensional changes are required.

What tolerance can you achieve?

Thickness tolerance can reach ±0.001 mm, with ultra-precision production down to ±0.0005 mm available for suitable specifications.

Can you manufacture custom Shim Rings?

Yes. We manufacture custom shim rings according to drawings, samples, existing tooling or machine requirements.

What materials are available?

We can manufacture shims from alloy tool steels and other specified materials according to the application and customer requirements.

Do you support small-batch production?

Yes. Custom and small-batch production are available according to product specifications and order requirements.
