New product SVR80
Space-saving even with the table traverse type while demonstrating excellent productivity and precision
The door opening part is designed to be wide to facilitate the easy removal of workpieces with a maximum swing of 820 mm.
Improved operability with a tilting control panel
The control panel adopts a design that allows it to be tilted as a standard and the operability has been improved.
Feature of SVR Series
- Grinding parameter can be easily by key-bord.
- To reduce the air cut time and improve safety in grinding operation,
- Spark on control device and Automatic overlaod retracting device are equipped as standard accessories.
High accuracy and High rigidity
- Spindle is supported by ultra-precision bearing.
- column is fasten to the bed at three points and this 3-point column support provides for slight adjustment of the spindle relative to the chuck.
Grinding head and feed device
- Spindle is supported by ultra-precision bearings with pre-load to improve rigidity.
- Head vertical feed is driven by AC servo motor.
- Head vertical feed is able o select step feed or continuous feed according to various materials of work pieces.
Base and magnetic chuck
- The slide-ways of base are lubricated automatically while tabel traverse and magnetic chuck table is lubricated with oil-bath.
- Magnetic chuck table moves between grindingposition and setting position for easy setting of work pieces.
- Magnetic chuck speed is continuously variable,so the best grinding condition can be set.
- Magnetic chuck force is continuously variable,so the warp of work piece can be ground.
・Column is rigid box type cast iron and fasten to the bed at three points.This 3-points column support provides for slight adjustment of the spindle relative to the chuck.
- Grinding parameter, rough and fine feed rate, feed volume, retract volume after grinding and etc. can be set easily by key-bord watching CRT. The position of grinding head is displayed on CRT.
- By using manual pulse handwheel, manual infeed is operated easily and exactly.
Selection of optional accessories
Grinding wheel flange
Standard accessory is triangle segment wheel flange. Other wheel flange for CBN or Diamond wheel will need according to materials of work pieces.
Direct measuring device
Direct measuring device is need according to output volume or tolerance of work pieces.
Should be select one coolant separator system.
In case of magnetize work pieces, basic selection is magnetic separator with the coolant tank.
In case of non-magnetize work pieces, paper filter type or centrifugal separator type is suitable.
In addition to the standard specification full cover (SVR 160 or more is a special accessory), dust collector is indispensable for consideration to factory environment.
Direct measuring device
CNC setting system of measuring device (electric control)
Automatic cycle grinding system
The standard specification of this machine is an indirect sized automatic cycle grinding system.
In addition, direct sizing equipment (limit switch type, electronic control type) can also be adopted by special specifications.
