The circular plate process route of TCT Circular Saw Blades

 

1. The circular plate process route of TCT Circular Saw Blades

A. diameter ≤200

Laser cutting → quenching → tempering → rough grinding → multi-roll calibration → secondary calibration → fine grinding → fine calibration

B. Diameter 200

Cutting plate → punching hole → cutting circle → quenching → tempering → coarse grinding → multi-roll calibration → semi-fine grinding → semi-fine grinding → fine grinding → fine grinding

2. The substrate process route of conventional TCT circular saw blades

A. laser cutting process route

Shearing plate → punching middle hole → trimming round → quenching → tempering → coarse grinding → multi-roll alignment → laser cutting → secondary reaming → (wire cutting → chamfering → riveting copper nails) → semi-fine grinding → (adjusting tension) → semi-fine alignment → (grinding middle hole → wire cutting keyway) → fine grinding → (rolling) → fine alignment → finishing

B. Process route of punching teeth

Shearing plate → punching middle hole → trimming circle → rough reaming → turning excircle → punching teeth → quenching → tempering → rough grinding → secondary reaming → (punching positioning hole) → wire cutting → (chamfering → riveting copper nail) → semi-fine grinding → (adjusting tension) → semi-fine correction → (laser cutting pattern → grinding middle hole → wire cutting keyway)

3. Process route of scribing saw

A. wire cutting

Shearing plate → punching middle hole → drilling through wire hole → quenching → tempering → coarse grinding → multi-roll alignment → wire cutting integral cutting → reaming → chamfering → fine grinding → turning steps → fine alignment → final inspection → grinding middle hole.

B. Laser cutting

Adopt adjusted 75Cr1 steel strip for processing

Laser cutting → secondary → reaming → chamfering of middle hole → fine grinding → turning steps → fine calibration → final inspection → grinding middle hole

4. Refers to the connecting knife plus process route

A. the current processing route

Shearing plate → punching middle hole → quenching → tempering → rough grinding → fine turning of inner hole → laser cutting → secondary → semi-fine correction → fine grinding → fine correction → grinding middle hole

B. Process route to be tested

Laser cutting → quenching → tempering → rough grinding → semi-fine correction → fine turning of inner hole → fine grinding → fine correction → final inspection → grinding of middle hole

5. Machining process route of milling insert

Mainly thick plate material

Cutting large plates → punching hoisting holes → quenching → tempering → coarse grinding → laser cutting → secondary reaming → semi-fine grinding → semi-fine correction → fine grinding → fine correction → final inspection → grinding middle holes

6. Machining process route of iron cutting saw blade substrate

A. the existing processing route

Plate shearing → (punching middle hole → cutting circle) → quenching → tempering → coarse grinding → multi-roll alignment → laser cutting → secondary → reaming → semi-fine grinding → semi-fine alignment → (laser cutting pattern and ring engraving) → fine grinding → fine alignment → final inspection → warehousing

B. Process route to be tested

Cutting plate → punching middle hole → cutting circle → reaming → roughly turning excircle → punching teeth → quenching → tempering → roughly grinding → twice → semi-fine grinding → semi-fine correction → laser cutting pattern → fine grinding → fine correction → final inspection → grinding middle hole
