Industrial Universal Grinding Machine CNC Practical Wear Resistant CG45

Product Specification

Universal Grinding Machine -CG45

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.

Machine description:

1.Machine base and main structure parts:

   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.

2. Automatic Centralized Lubrication system:

   An automatic centralized lubrication system lubricates the machine linear guides and ball screws continuously, which makes sure longer service life and high precision. And the cooling system is separated with machine base, which eliminates vibration and helps heat radiation.

3. Automatic system:

   Clamping in one time, including part clamping in one time, inner circle grinding, outer circle grinding, end surface grinding, cone grinding, profile grinding, and composite grinding in one machine.

   Equipped with Siemens CNC system as standard, and many optional units, such as work head auto-rotation device, auto diameter measurement device, auto end-surface measurement device, magnet-paper strips filter (for grinding slurry), and oil mist collector, etc.

4.Head stock rotates manually:

For the outer cone and inner cone grinding, the head stock can be rotated manually.

5. Head stock rotates automatically (Optional):

   The are optional precise DD motor (direct driving) and Heidenhain grating ruler, which can drive the head stock precisely through CNC system. It is very convenient for the outer cone and inner cone grinding.

DD motor (direct driving) (Optional)

6.​Wheel spindle:

   The custom outer grinding wheel spindle uses FAG high precise bearings, which are self-lubricated and easy maintenance. There is no metal to metal contact inside the spindle, which brings a very long time service life.The rotary speed of the high rigidity and high precise spindle can be adjusted to increase the linear speed when necessary. The inner grinding wheel uses a very high speed spindle, which can prevent resonance with the outer spindle.

7. CNC system:

   Siemens CNC system is applied in the grinder. And after a further development, a fool-proof human-machine interface is created in Chinese language. For better compatibility between the control system and the driving system, Siemens high performance servo motor is used. The system owns auto wheel dressing and auto offset performance, which makes sure the precision and stability of feeding and grinding.

8. ​Customized units: 

Tilt outer grinding +Inner grinding                       Straight outer grinding +Inner grinding                      Double Inner grinding

9. Custom outer diameter measurement and end surface measurement:

(Marposs) Outer diameter measurement, Measure and offset in real time        (Marposs) End surface measurement   ,Measure and offset                                                                                                                                                                                                 in real  time

9.Grinding method:
