Product Description

 

1.Highly Rigid Structure

The base column structure of this machine has high strength, high structure, and high stability. The main castings are made of high-strength and wear-resistant cast iron. After multiple aging treatments, the stress inside the machine is completely eliminated. The guide rails are highly wear-resistant, ensuring high precision and long life.

2.High Quality Grinding Head

This machine uses a high-precision spindle system originally supplied by a Taiwanese manufacturer and enjoys a high reputation in the world. The spindle uses P4-level ultra-precision bearings, with the taper end deflection within 2µm; it uses a V-3-level low-vibration motor. The whole machine rotates at high speed with low noise, no vibration, and has a large load-bearing capacity. It is suitable for heavy cutting and various molding grinding.

3.High-Precision Feed Structure

The front and rear left and right slides of this machine are pasted with high-grade imported guide rail wear-resistant sheets TUR CITE-B, and are precision scraped to ensure high precision. The column and spindle head guide rail are matched with high precision, and are most suitable for precision forming grinding of various grooves.

4.Automatic Lubrication System

When the spindle is started, the lubrication pump starts to automatically lubricate all screws and sliding surfaces, reducing wear and extending working accuracy and life.

5.Safe Dust Protection System

Dust-proof parts are installed between each moving part: sheet labyrinth rubber guards ensure the safety of the guide rails and the interior is dust-free and water-free.


 

1. Grinding Head

Manual grinding head,equipped with a rapid lifting mechanism, using a built-in motor, the spindle has good rigidity and high precision.

 

2. Electromagnetic Chuck

It is simple to operate,saves time and can be used continuously for more than 20 hours

3. Metal Hand Wheel

High-precision metal feed handwheel, easy to control.High-precision grinding model with an accuracy of 0.002MM.

4. Double V Guide Rail

Double V guide rail is adopted longitudinally, single V flat guide rail is adopted laterally, Hydraulic drive, high precision.

5.Resin Sand Cast Iron Body

The castings have good stability, high strength, and artificial aging treatment to ensure the dimensional accuracy of the castings finishing.
