CNC Drilling and Milling Machine with Self Centering Chuck for Tubesheet

Product Description

ubeCNC Drilling and Milling Machine self-centering chuck for tubesheet
heet PHD Series
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 drilling of connecting plate in the steel structure such as building,bridge,tower and so on.
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,save 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 heavy 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 BT50,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.
