Tool Grinding machine High Precision Swiss Type Step Down Grinding Machine CNC Grinder

Device description:

1. The body and components are cast by Milhanna high grade cast iron FC30, which is artificially normalized heat treatment and then treated by natural aging. Components are processed by YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment once clamping processing. Precision size can be up to micron level, to ensure high precision equipment basic components.

2. Machine guide rails and precision ball screws are continuously lubricated by automatic lubrication system to ensure longer service life and accuracy. The cooling system is separated from the body to eliminate vibration and favorable heat dissipation.

3.Equipped with Siemens 828D CNC automatic grinding system, and secondary development, man-machine dialogue fool operation, with many optional equipment to choose from, including inner hole grinding device, automatic end measuring device, automatic outside diameter measuring device, etc.

4. The grinding feed system is composed of a V and a flat track of hand-crafted precision shovel, with automatic lubrication system and C3 level precision grinding ball screw, which can achieve smooth movement, excellent repeated positioning accuracy and long track life.

5. The standard configuration of the grinding wheel spindle is rear four and rear two bearing structure. High precision dynamic and static pressure spindle can also be selected, which has the characteristics of high rotation precision, high dynamic stiffness, good vibration resistance, high grinding efficiency and good grinding surface quality. For special work-piece grinding, the grinding wheel speed can be adjusted, up to 3500 RPM and 60m/s.

6. The tail seat is designed to be both rigid and robust. A hardened alloy steel sliding cylinder encrusted in the cast iron body is designed to carry the MT4 top core. The jacking force of the sliding cylinder can be easily changed by adjustment knobs at the rear. Special accessories oil pressure tail seat with a pedal to facilitate unloading work parts.

7.Siemens numerical control system as the standard configuration, after secondary development, all Chinese operation interface, easy to use. Equipped with Siemens high performance servo motor, the equipment CNC system and drive system have better compatibility, at the same time with automatic sand repair and automatic compensation function, to ensure the stability and precision of feed and grinding.

Technical specification:

• Machine base and the main structure parts are made up of 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. That make sure the high precision of the grinders in micron level.

• The first part-feeding (Swiss-type) grinder in the domestic market. It has much high efficiency for slender-part step grinding.

• The CNC grinding program is developed by the software company and Hotman together. It is interactive.

The icons and buttons can move and be arranged freely. Complex grinding interface can be created under manual instructions, without program making.

(1) Advanced interface

(2) Process Total Custom

(3) Time Saving

(4) 19 inches liquid crystal monitor

• The operator can create a grinding interface quickly, by selecting the define diagrams and inputting the

parameters based on the shape of part.

• The precise linear guides and ball screws are lubricated continuously by the centralized lubrication units, which makes sure longer service life and precision. 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.

• There is internal liquid cooling system for the high precision electrical spindle to keep constant temperature.

A speed adjustment device can be added, and the maximum wheel linear speed can reach 90 m/s.

• Equipped with precision Schaublin chuck and precise holding jig.

• The robot which carries the part is driven by 3 ANCA servo motors, on precision linear guides, through ANCA control system.

• Use Marposs (Italy) or Keyence (Japan) laser measuring device. Make sure precise step grinding through all the length.

Real time measuring instrument

• Automation

Robot (Optional)

• Robot with 3 ANCA servo motors
• Part holder with 340-510 pieces
• Loading & unloading device with angle tilting 0-90°
