Outside surface grinding wheel to be automatic dynamic balancing technologyslewing ring bearing
For external surface grindin g, due to the large grinding wheel and for heterogeneous organization body, grinding wheel system center of gravity always deviating from the spindle center, high speed rotates inevitably lead to the grinding wheel system and its the whole machine tool vibration, which directly influences the service life of the machine. In this case, grinding processing will be difficult to achieve high precision, easy to cause the workpiece surface produce grinding vibration lines, corrugated degree increased.
Machine tool grinding wheel installed directly on the mechanical or other means of automatic dynamic balancing device, boot up quickly after direct approximation the equilibrium position, automatic balance more perfect and still can omit wheel static balance. The technology to promote the breakthrough of the grinding technology development, and to the great limit extend wheel, finishing with diamond and main shaft bearing life, reduce machine tool vibration, maintained for a lon g time the original precision machine tools.
Quickly remove internal surface grinding empty process technology
In all bearing grinding equipment, inner surface grinding machine level symbolic significance. This is mainly grinding aperture limits the size of the grinding wheel and the corresponding system mechanism set parameters, fundamentally limited the process system of rigid, and at the same time, the machining accuracy is higher. These require us must internal surface grinding process into in-depth research, in addition to maximum limit play machine and grinding wheel cutting ability outside, reduce auxiliary grinding time is the key to improve the grinding efficiency, because grinding idle accounts for about 10% of the whole grinding time.buy bearing
At present, the application both at home and abroad a wide range of rapid eliminate grinding empty process technology has the following kinds: co ntrol grinding technology, constant power grinding technology, the use of active measuring instrument technology and measuring electric spindle current technology.
CNC numerical control technology and ac servo technology
Ac servo motor and PLC programmable controller positioning module, servo amplifier can be connected to constitute a servo system, servo motor itself with optical rotary encoder, the output signal feedback to the servo amplifier can constitute a half closed loop control system. In high speed (3000 RPM) and low speed running can guarantee positioning accuracy, the use of servo system can complete jumping, fast hasten, finishing compensation, coarse and fine grinding, make the machine tool feed mechanism greatly simplified, greatly improve the performance reliability.double roller bearing
Ac variable frequency speed control technology
In the grinding of linear velocity with the consumption of grinding wheel to gradually reduce, the beginning and the end of the linear velocity than about 3-2. At present, in wheel grinding field has been using contour speed grinding, in order to improve the grinding efficiency, ensure grinding quality consistency, it can be adopted with programmable controller calculation function in every time after finishing grinding wheel to calculate the wheel radius, and then calculate the keep the wheel constant linear velocity of converter input frequency, and transfer to the ac frequency converter, so as to ensure constant linear speed grinding wheel.deep groove ball bearing
