And the grinding liquid by paper filtering and magnetic separation of water mist and dust; the dust suction device, the operator only need materials up and down, a person can see the number of machine tools, so the production efficiency is high, suitable for all kinds of automobile engine, motorcycle engine and diesel engine production manufacturers.
Main structure and technical characteristics
The bearing structure of high speed motorized spindle is in our own intellectual property and has been successfully used for many years in the high-speed grinding machine "gap cavity hole type oil return throttling liquid hydrostatic bearing on the prototype formed by an improved design. With a good bearing stiffness (up to 340N/ m), high rotary accuracy (radial, axial runout is less than 0.002mm), long service life (continuous operation for several years without maintenance) and other advantages.
On line automatic balance device of grinding wheel
CNC8312A use the IB-1404-A type high speed the world's most famous MARPOSS company or SBS company inside, non-contact automatic wheel balancer and SBS-4475 type dynamic balance control instrument, the balance maximum speed is 30000rpm, the vibration value of the sensitivity was 0.001 and the balance capacity of 400g - cm, the output signal is connected to the SBS-4475 automatic balance control instrument by cable.
A high precision hydraulic automatic tracking center frame is developed successfully
In order to adapt to the automatic grinding of shaft parts, CNC8312A has designed three point support hydraulic track type center frame, center frame clamping range of 30 to 65 of the maximum working pressure of 2Mpa. In order to reduce the central rack in the processing and assembly, as well as long-term wear error, the center frame can be used to adjust the axial parallelism, the upper and lower support relative to the center position can be adjusted slightly.
Hydraulic automatic tracking center frame has good rigidity, accurate control, fast response, simple operation, flexible adjustment and support the characteristics of high precision, it uses double lever structure principle, the symmetrical wedge type special angle drive block, can automatically track and adapt to the dimension and shape error of workpiece axis, the centering accuracy is 0.002mm.
numerical control system
Three two axis control control grinding wheel feeding system adopts machine (X axis), headstock's rotation system (C axis) and the worktable moving parts (Z axis). Headstock's rotation and the grinding wheel linkage, worktable and grinding wheel linkage. The machine tool numerical control system uses the German SIEMENS original 840D computer, the digital servo motor, the driving module, the power module. Motor torque: X axis 50Nm, Z axis 27Nm, C axis 27Nm. All electrical components are imported SIEMENS components, electrical cabinets installed three color lights. The red light is on when malfunctions happen, all electrical wiring should be neat and beautiful, unified and fixed.
