Main structure and configuration

1.Main structure and key parts material

The machine bed is made of high quality cast iron HT250 by normalizing heat treatment and furan resin sand casting. It has good rigidity, precision and wear resistance. The guide rail is equipped with lubricating device and dust-proof baffle. All moving parts are lubricated with lubricating oil and equipped with dust-proof device.

The lower seat adopts double Λ type slide rail design to ensure the best stability and avoid mud and dust intrusion; the middle seat adopts double Λ design to ensure smooth operation and the best straightness.

The outer diameter main shaft head is equipped with high-precision ball bearing, high rigidity, quiet rotation, ensuring that the user does not overheat for a long time.

The transmission system adopts high precision grinding screw rod,.

The working head can be adjusted at an angle of ± 5 °, which is suitable for the angle grinding of work pieces. The rotating speed of the working head can be adjusted, which is suitable for work pieces with different diameters.

All parts of the guide rail are lubricated by inching lubrication mechanism, which makes the working life longer and the maintenance simpler

2. electrical system

Schneider products are used for the electrical components of the machine tool. The electronic components and materials meet the ISO, CE and EMC standards, with long service life, strong anti-interference ability and stable operation;

3. Oil pressure system

 The lubricating system adopts components of Taiwan Wei xiang company, the oil level height can also be clearly seen, and there is a filter screen in the oil pump to protect the oil pump from damage.

4 . Cooling system

The cooling motor can provide enough coolant for grinding work piece, and can be recycled for a long time, so as to achieve the best surface roughness of grinding work piece. The water tank is equipped with an isolation tank to ensure that enough and clean coolant is provided to the grinding work piece.

5. NC system

This machine has micro hand wheel feed (can be divided into four speed adjustable), touch screen or micro button feed, the minimum feed resolution can reach 0.001mm, simple and easy to learn, stable operation; this machine tool is equipped with special safety emergency stop button, which can ensure the safety of human and machine. The feed servo motor and driver adopt Mitsubishi brand of Japan; the ball screw adopts THK screw of Japan to ensure the stability of micro feed accuracy and repeated positioning accuracy; the 7-inch control panel adopts delta touch screen, which has reliable performance and humanized operation; the size is easy to adjust; it is easy to learn and understand without programming.
