| MK2120B 数控内圆磨床 |
机床的主要特点 Main Characteristics
•机床采用德国西门子公司的808D两轴联动数控系统，内装PLC液晶显示。
•二轴均由伺服电机驱动滚珠丝杠，传动链简单可靠。往复轴配置无间减速器，以增强扭矩。
•机床床身采用整体浇铸，刚性好、变形小。
•机床床身导轨及工作台导轨采用平-V型贴塑导轨，刚性强，滑动性能好。
•进给机构导轨采用燕尾型滚针导轨。
•机床砂轮轴有两种形式可选择：一种是机械式砂轮轴，另一种是电动砂轮轴。电动砂轮轴由静止式变频作无级调速。
•机床夹具可由用户多种选择：有三爪卡盘、液压动力卡盘及液压薄膜式夹紧夹具。
•机床电箱为独立电箱。
•Siemens 808D two-axis linkage CNC system is dopted with PLC system.
•Two-axis ball screw driven by servo motors, drive train is simple and reliable. Reciprocating shaft configuration seamless reducer to increase torque.
•The machine bed adopts the casting piece with the features of good rigidity and small deformation.
•Flat-V guide way is adopted, feataring good rigidity & sliding performance.
•Feed mechanism guide rail adopts dovetail guide roller.
•There are two kings of wheel spindle: one is mechanical wheel spindle and electric gri wheel spindle whick its stepless speed regulation is carried out by freq inverter.
•Three pawl chuck and hydraulic power as well as hydraulic diaphragm fixture are used.
•Independent electrical cabinet is used.
