Titanium-Coated Circular Slitter Blades for Industrial Rewinding Machines

Product Overview

Hengye supplies titanium-coated circular slitter blades for industrial rewinding and slitting machines. Blade dimensions, base material and cutting edge geometry can be specified according to customer drawings and application requirements.

Available base material options include carbide, high speed steel, SKD11 and 9CrSi. The selected material and coating specification are confirmed separately for each order.

Coated Blades for Rotary Slitting

When selecting a coated replacement knife, both the blade body and the surface treatment need to match the cutting duty. The coating should be considered alongside the material being processed, operating conditions and maintenance requirements.

If an existing blade shows rapid wear, material buildup or inconsistent cutting, describe the problem and provide photographs of the working edge. This information helps establish whether the replacement requires a change in coating, base material or edge geometry.

Base Material and Coating Specification

The base material defines the underlying blade specification, while the coating is an additional surface treatment. HSS, SKD11, 9CrSi and carbide are separate material choices and should be identified clearly on the order.

Before manufacture, confirm the coating composition, coverage and any thickness requirements. State whether the treatment is required on the blade faces, bevels or other surfaces, and identify mounting areas that must remain untreated.

For repeat orders, provide the existing coating specification where available so the replacement can be reviewed against the same requirements.

Custom Dimensions and Cutting Edges

Outside diameter, bore and thickness are specified to match the shaft or holder. The drawing should also define the bevel configuration and working edge position.

Single-edge and double-edge configurations can be reviewed according to the cutting arrangement. Where the blade operates against an opposing knife or support surface, include the relevant assembly details.

Finished dimensions and tolerances should account for the agreed surface treatment.

Technical Specifications

Application Requirements

For rewinding and slitting enquiries, provide the material type, thickness, cutting method and operating speed. Include any adhesive layers, cleaning agents or process conditions relevant to the blade surface.

Machine compatibility depends on the blade dimensions, mounting arrangement and cutting geometry. These details should be confirmed before ordering a replacement.

Information Required for a Quotation

Frequently Asked Questions

Does titanium-coated automatically mean TiN-coated?

The exact coating composition must be confirmed. Specify the required coating designation rather than relying only on the general description “titanium-coated.”

Can the base material be selected separately from the coating?

Yes. The base material and surface treatment are specified separately, with the proposed combination reviewed for the application.

Can the blade be customized for an existing holder?

Yes. Provide the installation drawing, including the bore, thickness, mounting features and finished dimensional requirements.
