High quality CNC deephole drilling boring machines

Product Description

TK2225G series CNC deephole drilling boring machines adopt the double rectangle guideway on the bed body, which is treated by quenching treatment, to get the  excellent wear-resistance. The protection devices are installed between the guide ways, 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. Tk2225G series machines are specially designed for deep hole processing of cylindrical workpiece, 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.
