PMD Series CNC Gantry Drilling Milling Tapping Machine Product Features:
1. The servo slide drilling power head has the functions of drilling, reaming, chamfering and slot milling.
2. The machine tool is mainly composed of a bed and a longitudinal slide, a gantry and a transverse slide, a vertical ram drilling power box, a workbench, a chip conveyor, a hydraulic system, a cooling system, a centralized lubrication system, an electrical system, a pneumatic system and other parts.
3. The bed is equipped with a high-precision linear guide pair for flexible movement. The drive adopts an AC servo motor to drive the synchronous belt and the precision pitch ball screw pair for double-sided synchronous drive.
4. A moving slide is installed on the gantry beam. The slide is guided by a high-precision linear guide pair installed in front of the gantry beam. The drive adopts an AC servo motor to drive the synchronous belt and the precision ball screw pair to ensure high precision of the work.
Heavy Duty Gantry type PMD Series High Speed Drilling Milling Machine is mainly used for drilling holes in tube sheets, baffles and flanges in industries such as petrochemical, boilers, refrigeration and wind power flanges. It can also be used for drilling holes in connecting plates in steel structures such as buildings, bridges and towers.

1.Vertical CNC feed slide ram -type power head, its vertical sliding table and power head ram adopt cast iron (HT400) casting power head spindle motor adopts special spindle servo motor through the synchronous belt drive shaft torque at low speed, can withstand heavy cutting load, also suitable for carbide cutting tools high speed machining integrates tapping drilling and milling
equipped with automatic broach mechanism with butterfly spring, and hydraulic cylinder release cutter, easily to change the tools. It can be fitted with carbide inner cooling bit and HSS twist bit, while has the function of cleaning spindle conical hole。
The machine bed and worktable are made of high quality gray iron (HT300) casting, after twice tempering and heat treatment to remove stress.
In order to eliminate the resonance vibration produced in drilling milling process, and lengthen the life of alloy drilling bit, independent machine bed and work table structure are adopted
