Product Description

Newest CNC Horizontal Drilling and Boring Deep Hole Machine 
DBK-250     DBK-250A
 
Machine Summary
*CNC deep hole drilling and boring machine is mainly for the processing of cylindrical workpiece. This  machine can perform the process of drilling, boring ,expanding and roller burnishing, etc.
*The machine is equipped with CNC system. Besides machining through-hole, it can also process step  hole and blind hole, etc.
*The machine tool is suitable for production of special cylinder, coal cylinder, hydraulic machinery, high  pressure boiler tube, petroleum, military, electrics and airspace, etc.
 
Performance and Features
*The series deep hole drilling and boring machine adopts the double rectangle guideway on the bed  body, which is treated by hardening technology and has the excellent wear-resistance.
*The protection device is installed around the machine to avoid oil splash and leakage.
*The feeding system and oil feeder adopt servo motor control and gear-rack transmission to assure the  safety of the tool and the workpiece, the machine is easily operated and has the good rigidity.
*The spindle motor uses AC variable frequency motor with stepless speed regulation.
*It is applicable to the process of drilling and boring. When drilling the machine adopts internal chip- removal (BTA type), the cutting oil is supplied by oil feeder to cutting area, the chip is discharged through  the inner hole of drilling bar and is collected into the chip container located in the back part of the  machine.
*The machine is equipped with high efficient compound tool, the skiving roller burnishing tool can be  expanded and retracted automatically, it can achieve high efficient processing for oil cylinder production. 
 Germany WENAROLL tool can be chosen, and the customer can also use the tool manufactured by our  company.
*DBK-250 is equipped with workhead box, but isn't equipped with boring box or drilling box; DBK- 250A add to boring box or drilling box on the basis of the DBK-250, so higher efficiency machining  deep  hole for cylindrical workpieces.
