High Rigidity Body Structure

●The bottom of the centerless grinding machine is cast from high-grade cast iron (FC30) and normalized heat treatment. The double V-shaped slide rail design ensures the deformation of the inorganic body after long-term use. Fine adjustment of the upper and lower feeds up to 0.001mm.

●The grinding wheel trimming device can be adjusted to ±6°, and the workpiece and the guide wheel joint are accurate.

●The widest selection of models to meet a variety of grinding needs.

●The most complete selection of equipment to enhance operational functions and convenience.

●The most rigorous testing and quality control of the machine guarantees the best performance, precision and lowest failure rate

01、FANUC control system

02、Gantry type feeding mechanism (special device)

03、CNC three-axis roller type grinding wheel forming and trimming device

04、Multi-machine joint processing line

1、Precision hydraulic bearing

2、Precision grinding wheel Spindle and alloy bearing

3、Precision adjustment wheel Spindle and alloy bearing

4、Precision screw

5、Stable sliding table

1、Trimming device

The trimming device of the grinding wheel and guide wheel are hydraulically driven, constant speed, and the trimming seat is made of special alloy cast iron, which is processed by stewing and precision shovel,

and worn to ensure the flatness and straightness of the trimming.

2、Guide wheel with servo motor

The guide wheel uses the servo motor to move, can be arbitrarily adjusted to the appropriate speed, and the worm gear is used to directly drive the main shaft with the worm wheel. The workpiece is less affected by the vibration and gets better roundness.

3、Cooling fan

Reduces spindle oil to reduce thermal distortion and extend oil seal, spindle and alloy bearing life.

4、Pressure switch

The grinding wheel spindle bearing automatic lubrication system pressure switch, when the lubricating oil pressure reaches the rated number, the spindle motor can not be started or will automatically stop rotating to avoid the spindle dry rotation and damage.

5、Grinding wheel spindle circulating oil observer

To ensure the normal operation of the spindle by observing whether the oil goes bad.

6、Guide wheel trimming R angle

By adjusting this angle, the grinding accuracy of the workpiece is effectively changed when doing the passing through grinding.

7、Oil pressure switch

Used to change the trimming direction and speed. The angle of grinding wheel

8、The angle of grinding wheel

To accelerate the axial speed by adjusting the angle.

9、Feeding fine-tuning handwheel

Feeding amount per scale: 0.001mm

9、Spindle oil pressure gauge

The spindle has to work under normal oil pressure, when the pressure is too high, the machine will be stopped automatically.
