■ PMD 系列龙门移动式数控平面钻铣床 PMD Series CNC plate drilling & milling machine ◆适用范围 Application 本机适用于石化、锅炉、制冷、风电法兰等行业的管板、折流板、法兰盘的钻孔加工，也可用于建筑、桥梁、铁塔等钢结构 中的联接板钻孔。 This machine is suitable for drilling plate & pipe,baffle and flange in the petrochemical,boiler,refrigeration,wind power flange and other industries.It can also be used in the of connecting plate in the steel structure such as building,bridge,tower and so on.

　　◆产品结构特征 Product structure characteristics 1、机床主要由床身及纵向滑台、龙门及横向滑台、垂直滑枕式钻削动力箱、工作台、电气控制系统、液压系统、冷却系统、 排屑系统、集中润滑系统等部分组成。 2、机床采用龙门移动，工作台固定的形式，有效节省占地面积。 3、机床床身和工作立，提高了设备的稳定性并有效的减少了高速钻削过程中产生的震动。

　　4、机床的纵向和横向移动均采用精密滚柱型直线导轨副导向，极大地增加了设备的刚性。 5、主轴电机选用专用伺服电机通过同步带进行驱动主轴，无级调速，低速扭矩大，可承受重切削负荷，能适合硬质合金刀具高 速加工。 6、钻削主轴采用中国台湾精密主轴(内冷)，主轴锥孔 50，具有蝶形弹簧自动拉刀机构，可通过接杆装钻头或铣刀，液压缸松刀， 更换刀具十分方便。 1.The machine mainly consists of the bed and the longitudinal slide table,gantry and the horizontal slide table,the vertical sliding pillow drilling power box,the work table,the electric control system,the hydraulic system,the cooling system,the chip system,the centralized lubrication system and so on. 2.The machine adopts movable gantry and fixed worktable,se the floor area. 3.The machine bed and worktable are independent,which improves the stability of the equipment and effectively reduces the vibration generated during high-speed drilling. 4.The longitudinal and lateral movements of machine tools are guided by precision roller linear guide,which greatly increases the rigidity of the equipment. 5.The spindle motor uses a special servo motor to drive the spindle through the synchronous belt, stepless speed regulation, low speed torque,can withstａnd hey cutting load,ａnd can be suitable for high-speed machining of hard alloy tools. 6.The main axis of drilling is Taiwan precision spindle (internal cooling),the main axis cone hole 50,with a butterfly spring automatic broaching mechanism,through the rod to install the drill or milling cutter,the hydraulic cylinder loose knife,the replacement tool is very convenient.
