Product Description

CNC High-Speed Gantry Moving Drilling Machine for Plates Model TPM6040-2

This machine is gantry moving CNC high speed drilling machine, mainly uses for drilling and grooving work-pieces like tube sheets, flanges, can adopt both internal cooling carbide drills as well as external cooling twist drills. The two spindles can work simultaneously or independently, CNC control, easy operate, can realize automation, high precision, multi-scale, mid-small amount production.

 

Characteristics:
This machine is composited by machine bed & longitudinal slip plate, worktable, gantry& transverse slipway, vertical ram type drill box, chip conveyor, hydraulic system, pneumatic system, central lubrication system, electric system.
 

a. This machine is gantry moving, reduces the machine length, saves occupying area. Machine bed and gantry adopts steel plate welding structure, have done the manual aging treatment, the precision is stable. Worktable, longitudinal slip plate, transverse slipway and ram etc are iron casting parts. There are T slots distributed on the worktable surface, for clamping tube sheets and fixture.
b. Movable gantry is installed the left and right longitudinal slide carriages, which is right-angle bending plate welding steel structure. A set of transfer mechanism consisting of AV servo motor and high precision rack assembly on the left and right sides respectively. The gear assembly are connected with longitudinal slide carriages. When the AC servo motor rotates, it drives the gear to move along the rack(X axis), the slide carriage moves along the guide at the same time.
c. The movement of drilling  box (Y axis) is guided by two staged high precision linear ball screws equipped in front of gantry beam, and driven by servo motor and large pitch ball screws, the servo motor is transmitted by timing belt with rotation of large pitch ball screw. Leading screw is pre-tightened by double nuts, removed the gap. Y axis equips with Heidenhain Grating Scale, formed fully closed loop control, with high transmission precision.
d. The vertical movement of Ram type drilling box (Z axis) is guided by linear guide which locates at both sides of ram, driven by servo motor and ball screw.Dydraulic balancing, every drilling box can work independently. Z Axis equips with balance cylinder, if the Z axis motor belt broken, it will drop very slowly to stop until touches the buffering cusion which locates between bearing base and screw nuts base, to avoid Z axis slide falls down accidently.

e. The drilling box is rigid high precise spindle, adopts BT50 internal cooling spindle from Taiwan, with blowing device. Also equips with Taiwan hydraulic tool cylinder, using hydraulic -disc spring to do automatic tool de-clamping, tool pulling, with tool status monitoring device to check the tool clamping and effective safety co-locking protection device. Easy to change tools. The spindle is driven by spindle servo and timing belt, spindle speed is 30~3000r/min, large rotation speed range.

f. The hydraulic system is for auto tool device and weight balance of ram type drilling box, unified oil supply; all the hydraulic units are from imported brands or joint venture companies, for easy maintenance and solving oil leaking, all the design adopts accumulative valves.
