High speed grinding

Configura the transducer device , the GW linear speed can reach 50m/sec to achieve the best performance surface accuracy.


Hydrostatic bearing
The GW spindle is support by the Hydrostatic bearing, the spindle completely floats in the oil film without contact to housing when working, thus there is no friction, which ensures high precision grinding and long working life.

High accuracy GW spindle
The GW spindle is made of  high-grade alloy steel SNCM-220H, heat treeated and then sub-zero treated, precision grinding, thus the spindle has high precision and high rotation speed.


High rigidity spindle workhead

Adopt servo drive motor, infinitely variable speed and make high speed and high precision grinding.

Oil bath lubrication tailstock

The oil bath lubrication system can make sure the toilstock achieve high movement operation. Also configura a fuel gauge for opeator`s convenience checking and inspection.

Henfux new products that was through our independent research and development. Base on Henfux engineer`s understanding of grinding machine and Henfux`s currently resource, this new model HFU-3210 cylindrical grinding machine is make a great succeed. The main feature of this machine are

>Rigid Meehanite box-tyoe machine bed. All of Henfux machine`s machine body is provide by ourself from our casting factory.

>Hydrostatic spindle technology. Base on our centerless grinding machine completely mature Hydrostatic spindle technology, we also configurate the Hydrostatic spindle on HFU-3120, it is the first one who use this on cylindrical machine.

>The grinding speed could reach 50m/sec, industry leading!
