數控鏟齒磨床系列CNC Relieving Grinding Machine series

GD8925數控鏟齒磨床是在傳統機械式鏟齒車床的基礎上經過數控化改造而成的數控機床，加工精度可穩定達到DIN3968標準和國標GB/T6084-2001 A*。

GD8925 Model of CNC Relieving Grinding Machine is transformation on the basis of the traditional mechanical relieving lathe. Its machining precision can achieve stable DIN3968 standard and GB GB/T6084-2001 Grade AA.

GD8925數控鏟齒磨床采用西門子828D數控系統，實現交流伺服電機，全閉環控制，取消了傳統鏟齒磨床的主軸變速箱、槽數系統、差動系統和凸輪系統，無需掛輪、凸輪即可實現高精度螺旋線運動和鏟背運動的數字控制，以及徑向、斜向、軸向鏟背，磨頭采用伺服電機實現等線速度磨削，使加工出的工件質量更穩定。

GD8925 CNC Relieving Grinding Machine is using Siemens 828D CNC system, AC servo motor, the closed loop control, the machine is cancelled the traditional relieving grinder spindle gearboxes, slot number system and differential system and cam system, needless changing gear while the cam to realize the high precision spiral movement and relieving with NC. It can be relieving of radial, oblique, axial. Its grinding head adopt servo motor to realize constant linear velocity grinding, machining the work-piece quality in more stable.

GD8925A型數控鏟齒磨床是西安共達精密機器有限公司積累8925機床改造的經驗，全新研發的新型數控機床，該機床主軸采用新型分度機構、液壓自動壓緊，具有磨削精度高、操作方便的特點。

GD8925A type of CNC Relieving Grinding Machine is by experience accumulation of improving on mechanical machine 8925 type with Xi’an Gongda Precision Machine Co., Ltd.(XGPMC). It is a full new type of machine with new research and development, the machine tool spindle adopts new type of automatic dividing mechanism, Centers clamp with hydraulic pressure in automatic, this type machine has the characteristics of high grinding accuracy, convenient operation.

該系列數控鏟齒磨床配備公司自主研發的圖形化、數字化自動編程系統。可以加工各種滾刀和成型銑刀，不僅可以加工單頭直槽的滾刀，也能加工多頭及螺旋槽滾刀，還能進行高精度多頭蝸桿的磨削加工。加工過程自動化程度更高，降低了工人的勞動強度。

This series of CNC Relieving Grinding Machine equipped independent research and development of graphical and digital automatic programming system by XGPMC. It can process all kinds of gear hob and forming milling cutter, not only can processing single start straight groove hob, can also process multi-starts and spiral groove hob, and can perform high accuracy multi-start worm grinding processing too.

Work-piece processing with higher degree of automation, so it reduces the labor intensity of workers。
