【Main use】
The machine is mainly used for grinding nuts for automobile steering screws and ball-screws in massive production
【NC system configuration】
1、FANUC 0iMC or SIEMENS 828D, controlling 3 NC axes
2、Programmable axes are designated as followers
Axis X Cross-feed of wheelhead full close-looped
Axis Z Table longitudinal traverse full close-looped
Axis C Rotation of work spindle full close-looped
【Working accuracy】
Thread accuracy achievable
Limit lead deviation 0.005mm
Accumulative error at a length of50mm 0.009mm
【Technical characteristics】
1、Wheel dressing is conducted by a formed diamond roller
2、a newly-developed workhead structure doubles work spindle speed, thus increasing greatly machine productivity
3、Special-built soft program makes the machine have automatic grinding cycle, wheel dressing and self-compensation for wheel dressing amount
4、Wheel spindle employs a high speed E-spindle
5、Users can choose grinding modes between one-way or two-way auto-grinding cycle
6、Online device for pre-cut thread alignment can be an optional configuration to users
7、Efficient centrifugal oil mist exhauster is available
