数控铲齿磨床系列CNC Relieving Grinding Machine series
GD8925数控铲齿磨床是在传统机械式铲齿车床的基础上经过数控化改造而成的数控机床，加工精度可稳定达到DIN3968标准和国标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数控铲齿磨床采用西门子828D数控系统，实现交流伺服电机，全闭环控制，取消了传统铲齿磨床的主轴变速箱、槽数系统、差动系统和凸轮系统，无需挂轮、凸轮即可实现高精度螺旋线运动和铲背运动的数字控制，以及径向、斜向、轴向铲背，磨头采用伺服电机实现等线速度磨削，使加工出的工件质量更稳定。
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型数控铲齿磨床是西安共达精密机器有限公司积累8925机床改造的经验，全新研发的新型数控机床，该机床主轴采用新型分度机构、液压自动压紧，具有磨削精度高、操作方便的特点。
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.
该系列数控铲齿磨床配备公司自主研发的图形化、数字化自动编程系统。可以加工各种滚刀和成型铣刀，不仅可以加工单头直槽的滚刀，也能加工多头及螺旋槽滚刀，还能进行高精度多头蜗杆的磨削加工。加工过程自动化程度更高，降低了工人的劳动强度。
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。
