Indexable Carbide Insert Full Radius Slotting Cutters

Scope of application
(1) To process gears with shoulders and double or multiple gears with narrow empty tool grooves, only gear shaping can be used. This is because: Shaper knives require very little space to "cut out", w hereas hob cutters interfere with large diameters. (2) For processing herringbone gears without empty tool grooves, only tooth shapers can be used; (3) For processing internal gears, only tooth shapers can be used. (4) To process worm gear, only hobbing can be used. (5) For machining helical cylindrical gears, both are available. But hobbing is more convenient. When inserting helical gears, the tool spindle of the gear shaper must be provided with a helical guide rail to provide the helical motion of the gear shaper, and a special helical gear shaper needs to be used, so it is very inconvenient.

Ways to increase productivity
1. Increasing the circular feed can reduce the manoeuvring time, but the circular feed is proportional to the yield during the idle stroke. Therefore, the problem of the yield of the tool must be solved.
2. Exploit the potential of the machine tool to increase the number of reciprocating strokes and adopt high-speed gear shaping. The number of reciprocating strokes per minute of some gear shapers can reach 1200 to 1500 times/min, and can reach 2500 times/min. It is 3 to 4 times higher than the commonly used ones, which greatly improves the cutting speed and reduces the maneuvering time required for gear shaping.
3. Improve the tool parameters, improve the durability of the gear shaper, and give full play to the cutting performance of the gear shaper. If the W18Cr4V gear shaper is used, the cutting speed can reach 60m/min; increase the rake angle to 15° and the relief angle to 9°, which can increase the durability by 3 times; It can also increase the durability by about 30%.
