Detailed description

CNC Grinding Machine

for Carbide Roll Rings Forming

I. Brief Introduction:

This machine tool is special NC equipment for grinding the outer circle and groove of the high-speed steel wire/ rod roll rings (carbide). It has won the Science and Technology Progress Award of the Ministry of Machinery and belongs to the national high-tech products. And it has been widely used in many high speed steel wire/rod rolling enterprises in China and exported to overseas.

II. Advantages:

1. Grinding head guide way adopts closed self-lubricating guide way with good rigidity.

2. The spindle adopts imported precision bearings with high rotating accuracy.

3. The roll ring clamp adopts self-centering elastic expanding sleeve clamp, which is high centering accuracy and convenient work piece clamping.

4. Siemens CNC system is highly automated and reliable.
