In the relative both sides of bit base, one end of bit base is provided with clamping end, and cutter tooth A and cutter tooth B cutting edge are close to clamping end.
Described cutter tooth A has 3 ~ 30, and cutter tooth B has 3 ~ 30.
There are 2 ~ 5 finishing teeths in described cutter tooth A, there are 2 ~ 5 finishing teeths in cutter tooth B.
Described cutter tooth A and cutter tooth B rise per tooth are between -0.2 ~ 0.3mm.
Described cutter tooth A has two cutting edge A, cutting edge A to form Y types with bit base, and cutter tooth B has two cutting edge B,
Cutting edge B forms Y types with bit base.
Described cutter tooth A anterior angle between 6 ° ~ 15 °, side edge relief angle and top relief angle between 0 ° ~ 5 °, land it is wide 0
Between ~ 0.2mm, cutter tooth B anterior angle between 6 ° ~ 15 °, side edge relief angle and top relief angle between 0 ° ~ 5 °, land it is wide 0 ~
Between 0.2mm.
Described bit base, cutter tooth A, cutter tooth B and clamping end is integrally formed by Hardmetal materials and is made.
Described clamping end is provided with the mounting hole for clamping cutter.
The present invention has advantages below：
1. the broaching tool is manufactured using hard alloy, it has the advantages that intensity is high, wear-resisting, service life is long, passes through one
Shaping manufacture so that broaching tool rigidity is high, is advantageous to improve machining accuracy, and can make the broaching tool time processing compressor gas
Two chamferings of cylinder vane slot, avoid using two broaching tools, saved production cost, simplified broaching tool processing technology and chamfering
Processing technology, improve processing efficiency；
2. the broaching tool has the advantages that cutter tooth is sharp, stock-removing efficiency is high, cutting surface crudy is high；
3. by using threaded connection clamping broaching tool, have the advantages that bonding strength is high, clamping precision is high.
