【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
