Main Outlook

Main Performances

Features and Performance

With the screw pump adopted in the hydraulic drive system and it gains features of smooth running and low running noise.
Equipped with sleeve type big conical degree hydrodynamic bearing shafting with integral bearing bush in wheel head, high rotary precision and rigidity are realized.
The feeding guideway uses antifriction & plastic-filming guideway, thus promoting the smoothness and vibration resistance of low-speed operations.
Besides the advantages of high machining accuracy, reasonable overall layout and attractive appearance, the operating handles of the machine are centralized arranged and viesualization, thus to make the machine easy to control and safe to operate.
With the function of semi-automatic plunge-cut grinding and longitudinal grinding controlled by the sizematic grinding or automatic measuring instrument, the machine of BGB/BUGB type (high-precision semi-automatic) can be used for processing small lot or batched high precision parts.
For the BGB/BUGB type machine (high-precision semi-automatic), all the grinding functions and sequence of operation in the processing cycle are controlled by PLC.
