CNC Horizontal Double-spindle Deep Hole Drilling Machine Model DD25/2

Product description

This machine mainly adopts for drilling tube sheets for the industries of Chemical, Thermal Power Plants Petroleum, Pharmaceuticals and Nuclear etc., Equips with lots of safety auto protection, so it realizes the auto safety monitoring. All the key parts like linear guide, CNC system, ball-screws, inner cooling connectors, servo motors and drivers, reducers, valves, hydraulic pumps, and etc. are adopting global well-known brands, thus the machine quality is high and with steady performance.
 
This machine is using both BTA drill (internal chipping) and Gun drill (external chipping), the two spindles can drill simultaneously, and the distance between the two spindles is adjustable.
 
The Max. Work-piece diameter is φ2500mm, Max. Drilling depth is 800mm. Surface roughness of drilling is Ra6.3~Ra3.2, hole dia. Precision is IT9~IT10, straightness of drilling hole is 0.3-0.8 mm/m.
 
The machine body and worktable are independent, machine vibration will not affect work-piece, and furthermore, worktable is made by casting part to realize stable precision. 
 
Chip conveyor is adopting Plate-Chain type, the process of chipping will be done automatically. Coolant will be re-cycled after filtering. Equips with industrial refrigerating machine to cool down the coolant, ensure the stability of drilling process.
 
Using Spain SIEMENS 840D as CNC system, adopts electric hand wheel, easy to use and operate. System is able to compensate the positioning precision for each axis, once confirming the central position, the system will automatically do the programming, as well as optimize the order of drilling, dramatically increase the efficiency of machine. Converting CAD drawing to CNC parts program by programming software. Optimizing the order of drilling to increase efficiency of drilling.
