Product Description

Product Description

1.Machine base and the main structure parts are made in meehanite (inoculated) cast iron FC-30.
After normalizing heat treatment, the cast iron base and parts will stay for natural aging treatment.
The cast iron base and main parts are machined in the world top class machines, such as YASDA, MITSUI SEIKI, TOSHIBA, ELB, etc in one-time clamping, with an accuracy of micron level, that ensures a fundamental precision of machine.
2.The first and creative part-feeding grinder domestically, addressing the problem of small feeding from
the outside diameter and low grinding efficiency. In the rough grinding stage, the grinding surface starts from the end surface, with big grinding volume and high efficiency. And for those parts of small diameter for grinding, it is even more advantageous.
3. The CNC program is co-developed with Hotman, which is a highly automatic grinding system, where the  icons and buttons can be moved and be arranged again freely. Its touch screen is interactive. Complex step grinding interface can be created under easy manual instructions only, unnecessary with an traditional CNC program making.
4.The operator can create a grinding interface quickly, by selecting the define diagrams and inputting the
parameters based on the shape of part.

5.The precise linear guides and ball screws are lubricated continuously by the centralized lubrication units automatically, which makes sure the precision for a longer service life. The cooling system and lubricating system are separated from the machine base, which eliminates the vibration to the base and is better for heat radiation.
6.There is an internal liquid cooling system inside the high precision electrical spindle to keep a constant temperature. Additionally a speed adjustment device can be equipped, and the maximum wheel linear speed can be up to 90 m/s, which meets the grinding requirement of different diameters with high efficiency.
