MM52125型精密龙门式导轨磨床(图1)是险峰机床厂的新产品。该机床适用于磨削各种不同形状的机床导轨面,特别是经热处理后的导轨面,也可磨削大平面。该磨床为大型精密机床,由双立柱、顶梁及床身组成一封闭的刚性框架结构。横梁沿立柱导轨可作升降运动,周边磨架与万能磨架分别悬挂在横梁上。工作台的往复运动由液压驱动,采用变量变向叶片泵与双活塞杆油缸组成的闭式油路系统,可作无级调速。为了保证 MM52125 precision gantry rail grinder (Figure 1) is a new product of Xianfeng Machine Tool Works. The machine is suitable for grinding a variety of different shapes of the machine guide rail surface, especially after heat treatment of the guide rail surface, but also grinding large plane. The grinder is a large-scale precision machine tool. The double-column, top beam and bed form a closed rigid frame structure. Beam rails along the column can be used for lifting movements, the peripheral mill and universal mill were hung on the beam. Workbench reciprocating motion by the hydraulic drive, variable variable vane pump and dual piston rod cylinder closed oil system, can be used for stepless speed regulation. to ensure that
