1.机床采用进口(如德国西门子)计算机控制系统,砂轮架进给,工作台移动,砂轮修整器进给及补偿,均由交流同伺服电机通过滚珠丝杆驱动。
2.加工零件的尺寸精度即可用定程磨削的方法获得,也可用自动量仪实现,当用自动量仪时,精度可达0.008mm(直径方向)。
3.砂轮最高线速度为60或50米/秒,砂轮主电机用变频调速装置控制转速,使砂轮线速度保持恒定,砂轮主轴轴承采用独特的液体静动压轴承,具有很高的刚性。
4.砂轮修整采用台阶形金刚石滚轮修整,具有砂轮磨损补偿和自动修整补偿功能,砂轮修整精度半径方向可达0.0015mm。
5.机床床身道轨采用聚四氟乙烯贴塑道轨,砂轮架道轨为贴塑液力卸荷道轨,道轨的耐磨,抗震性能好,使用寿命长。
6.机床冷却系统采用重力式纸带过滤机(配有磁性分离器),提高了冷却液的净度及使用寿命,机床还可根据用户需要,配置自动上、下料装置(机械手)。
7.根据不同零件类型，可设计为单砂轮斜切入式，双砂轮式，双轴三砂轮式等形式的机床（即：MKS1632A、MKS1632B、MKS1632C等）。

MKS1632A SERIES CNC HIGH SPEED ENDFACE CYLINDRICAL GRINDER
MAIN FEATURES:
This series grinders are designed specilly for automobile and enging manufacturing. In the grinder and its versions,internationally advanced computer control system is used.
Grinding wheel set with oblique cutting method is applied ,which make the grinding of cylidrical, cylidrical and end surface,formed cylindrical surface,multi stages oxle cylidrical(include shoulder surface)and cylindrical slot available at one working cycle.The grinder is of the functions of correcting the grinding wheel with diamond roller,automatic compensating and measuring with radial and axial meters.Progammable controllor(PC)is also used in the control system.the grinder has both the features of high machining accuracy and high efficiency.it is suitable that the grinder is used for batch production to manufacture shaft class elements,like axle shaft ,gear shaft,different shaft case,flange and so on.
1.The grinder is equipped with the computer control system(SIEMENS CORP.GERMANY).Grinding wheel set feeding ,table travelling,feeding and compensating of the wheel correcting.are drived by AC servo motor through roller screw.servo system is accurate and reliable.
2.The dimension accuracy of the machined part can be obtained by NC definite distance grinding or NC automatic meter ,As using automatic meter,machining accuracy may achieve 0.008mm(in radial direction.)
3.The maximum grinding wheel linear speed is 60m/s or 50m/s.The speed of main grinding wheel motor is controlled by frequency converting speed regulator,which makes the line speed constant with the wheel wear and tear.The wheel bear is liquid static and dynamic pressure bear we specially design.The bear is of high stiffness.
4.Muti stages diamond roller mechanism,which is of the function of wheel compensating and automatic correcting ,is used to correct the wheel wear.The correcting accuracy may achieve 0.0015mm in radial direction.
5.The slides sticked with polyfluortetraethylene plastics are used to be the grinder slides. The wheel set slide applgies hydraulic unlooding slide with plastics sticked.The wearing resistant and vibration strength are good,and the application life is long.
6.For cooling system,gravitation filter with paper belf equipped with magnetic separator is applided.Therefore,the cleanliness and application life of the cooling liquid increased.According to the customers requirements.automatic loading and unloading attachment(mechanical manipulator)can be provided.
