In recent years, due to the development of the grinding wheel, control, measurement and vibration of TIMKEN bearing grinding technology, new technology and equipment has been applied, mainly has following several aspects:
1 commonly used high speed grinding technology, internal surface grinding wheel line speed can reach 60 ~ 80m/s; line speeds of up to 120m/s outer surface grinding wheel.
2 grinding wheel line speed, puts forward new requirements on the dynamic balance, which tell the grinding machine grinding wheel dynamic balance device are used to make up the told grinding wheel unbalance.
3 in order to adapt the TIMKEN automation of bearing ring grinding, grinding technology of CBN wheel began to use in the TIMKEN bearing ring grinding. Compared with ordinary grinding wheel, its abrasion ratio as high as 4000 ~ 10000, equivalent to about 150 times the ordinary grinding high efficiency, especially suitable for the automatic high speed grinding.
4 artificial granite as TIMKEN bearing grinder bed material, because of its strong rigidity, good anti vibration performance, low thermal conductivity and the manufacturing cycle is short, and is gradually adopted by the machine tool manufacturer in the world.
5 spindle and TIMKEN bearing grinding machine spindle with frequency converter, through the PC or CNC programming control, stepless speed regulation in order to obtain the maximum and the processing quality, the best sales and keep the wheel speed constant.
6 grinding technology development is improving, measurement feedback (inductance active measurement) application system of computer, the plunge grinding, size measurement and feedback control becomes a closed loop system.
7 with the development of technology of hydraulic components, hydraulic system of TIMKEN grinding machine for bearing ring have also been updated, the widespread use of variable vane pump, the hydraulic oil working temperature control in 5 ℃ above room temperature level, to overcome the influence of hydraulic system of the machine tool working accuracy and processing accuracy.
Composite grinding technology of 8 on the same machine on the two processes are combined grinding has been applied in the TIMKEN bearing ring grinding, both to ensure the high machining accuracy, and greatly improve the processing efficiency of product.
9 because of numerical control technology and hot components (servo motor, ultra precision roller screw and encoder) the rapid development of technology, makes the PC and CNC control technology is widely used in the control system of TIMKEN bearing ring grinder, CNC system can be used for bearing ring grinder TIMKEN the action of each mechanism and the cycle parameters programmed control, storage and modification; grinding wheel dressing device through the NC coordinate to achieve a straight line or circular arc wheel dresser requirements.
