機床的主要特點 Main Characteristics
?機床采用德國西門子公司的808D兩軸聯(lián)動數(shù)控系統(tǒng)，內裝PLC液晶顯示。
?二軸均由伺服電機驅動滾珠絲杠，傳動鏈簡單可靠。往復軸配置無間減速器，以增強扭矩。
?機床床身采用整體澆鑄，剛性好、變形小。
?機床床身導軌及工作臺導軌采用平-V型貼塑導軌，剛性強，滑動性能好。
?進給機構導軌采用燕尾型滾針導軌。
?機床砂輪軸有兩種形式可選擇：一種是機械式砂輪軸，另一種是電動砂輪軸。電動砂輪軸由靜止式變頻作無級調速。
?機床夾具可由用戶多種選擇：有三爪卡盤、液壓動力卡盤及液壓薄膜式夾緊夾具。
?機床電箱為獨立電箱。
?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.
