Custom Circular Slitter Knives with Drawing-Specified Bore and Thickness

Product Overview

Hengye supplies custom circular slitter knives for industrial converting equipment. Outside diameter, bore, thickness and cutting edge geometry can be specified to match the machine’s mounting and cutting arrangement.

This product is intended for replacement knife enquiries and non-standard circular blade requirements supported by customer drawings or samples.

Fit and Mounting Requirements

A circular knife must locate correctly on its shaft or holder. Bore fit, blade thickness and mounting features determine its position within the cutting assembly.

For replacement orders, copying only the outside diameter can leave important installation details undefined. The drawing should include the mounting dimensions and any features used to locate or secure the knife.

Edge Configuration for the Cutting Method

The cutting edge should be selected together with the material and machine configuration. Different bevel profiles and edge arrangements may be required for paper, plastic film, adhesive materials or fabrics.

Confirm the required edge orientation and cutting arrangement before manufacture. Where the blade works with an opposing knife or support surface, provide the relevant assembly details.

Technical Specifications

Typical Applications

Circular slitter knife enquiries include paper converting, plastic film processing, adhesive tape slitting and textile or nonwoven cutting.

The final specification should identify the material thickness and cutting arrangement. A single knife design should not be treated as suitable for every material listed.

Replacement Knife Checklist

Provide the original drawing where possible. If measuring a used knife, record the bore, thickness and mounting features, and state whether the outside diameter has changed through sharpening.

Include the machine model, material being cut, operating speed and quantity. Installation photographs are useful when the mounting arrangement is not fully shown on the blade drawing.

Frequently Asked Questions

Can the bore and thickness be customized?

Yes. These dimensions can be specified on the approved drawing to match the installation.

Can a worn blade be used as the only reference?

A worn sample may not show the original cutting geometry. Provide original dimensions or identify the worn areas for review.
