【Main use】
The machine is mainly used to hard-mill the thread of ball-screw in one pass,and it can also be used to mill Acme thread。
【NC system configuration】
1、There are three programmable axes controlled by the SIEMENS 828D CNC system,including three synchronous ones。
2、No. of programmable axes
Axis Z: Table longitudinal traverse
Axis X: Cross feed of cutter rest
Axis C: Rotation of work spindle
【Working accuracy】
1、The spiral accuracy: over a length of 300 0.052mm
2、the consistence error(minor diameter) 0.05mm
【Technical characteristics】
1、The hardness of thread flanks can not be decreased because of hard-milling technology
2、The machining cost can be reduced and the machining efficiency can be enhanced 30% by making use of mountable & indexing CBN inserts
3、The machining zone is cooled with compression air, so the pollution caused by coolant can be eliminated
