The large center bore and keyway support repeatable shaft positioning when produced to the approved drawing. Controlled machining, heat treatment for applicable steel grades, flatness control, and finish grinding help maintain dimensional consistency and cutting-edge quality.
Standard and custom round knives are available. To confirm the correct blade, provide the existing drawing or sample, outer diameter, bore, thickness, keyway, bevel direction, machine model, processed material, line speed, and required quantity.
Technical Specifications
Product Detail
The product image below shows the representative concentric grinding zones, large center bore, and single keyway. Final edge angle, bore tolerance, keyway dimensions, and runout requirement must follow the approved drawing.
Product Features
Precision circular edge: Finish grinding supports clean slitting and consistent edge quality.
Controlled mounting geometry: Bore and keyway dimensions are manufactured to the approved replacement drawing.
Stable flatness and runout: Process control supports smooth rotation and reliable cutting at operating speed.
Wear-resistant material options: Blade grade and hardness can be matched to the film, filler, line speed, and service-life target.
OEM and ODM manufacturing: Custom diameter, bore, thickness, holes, keyways, bevels, coatings, and packaging are available.

Installation and Maintenance Notes
Clean the shaft, blade seat, spacer, and clamping surfaces before installation.
Confirm bore size, keyway orientation, bevel direction, and cutting direction before tightening.
Use balanced clamping force and verify that the blade sits flat without trapped debris.
Check runout, alignment, overlap, and cutting clearance before full-speed operation.
Start at reduced speed and monitor cutting quality, heat, vibration, noise, and motor load.
Protect the cutting edge during storage and record blade life and failure mode for repeat orders.

Frequently Asked Questions
Q1. Is the A105 × 70 × 1.2 mm model available as a custom blade?
Yes. The diameter, bore, thickness, keyway, holes, bevel, material, hardness, coating, marking, and packaging can be manufactured from an approved drawing or sample.
Q2. Which materials are available for round slitting blades?
HSS, tool steel, stainless steel, and application-specific grades are available. Selection depends on the processed material, speed, edge geometry, contamination, and target blade life.
Q3. Can you control flatness and runout to our drawing?
Yes. Required flatness, parallelism, concentricity, and runout values should be stated on the drawing so the inspection method and production route can be confirmed before quotation.
Q4. Are coatings available?
TiN, TiCN, DLC, and other suitable coatings may be available. Coating selection is confirmed after reviewing the base material, edge finish, cutting material, operating temperature, and cleaning method.
Q5. Can you manufacture from an old blade sample?
Yes. Mark the installation face, rotation direction, and working edge on the sample. Photos of the blade holder and current failure condition will improve the engineering review.
Q6. Are sample orders available?
Sample orders can be arranged for eligible standard or custom models so fit, rotation, edge direction, and cutting performance can be evaluated before a larger order.
Q7. What is the production lead time?
Lead time is confirmed after the drawing, material, tolerances, coating, quantity, inspection documents, and packing requirements have been reviewed.
