Machine Brief :

This machine is a three axis, efficient, high-precision, and highly automated quartz glass deep hole machining machine. The cutting tool rotates and feeds,the machining accuracy and surface roughness can be achieved through one continuous drilling. This machine is controlled by CNC system for easy operation and improving safety. It also has the function of automatic cycling. Therefore, it is not only suitable for small batch processing, but also especially for the requirements of mass production. It can drill not only through hole , but also blind hole and step hole .

Main part of machine :

Drilling hole diameter range : Φ 10-Φ50mm

Max. Drilling depth and hole diameter ratio is :80:1

Max. Drilling depth: 1500 mm

Working table : Can move vertically (Y direction) and horizontally (X direction), CNC control; Equips with fixed T-slot working table .

X-axis: Control the lateral movement of the workpiece; Ball linear guide rail; The servo motor drives the ball screw to realize the movement in X-axis direction ; CNC control.

Y-axis: Control the movement of the working table in the vertical direction; Roller heavy-duty linear guide rail; The servo motor drives the ball screw through a servo reducer to achieve Y-direction movement; CNC control; Servo motor with brake .

Z-axis: Control cutting tool feed movement; Rolling linear guide rail; The servo motor drives the ball screw through a coupling to achieve Z-direction movement , CNC control; The cutting tool feed rate can be stepless .

Drill box: Drive the cutting tool to rotate ; The spindle is driven by a servo main motor, synchronous belt, and synchronous pulley, achieving stepless speed regulation, main motor power 7.5kw,, and the max. spindle rotation speed is 5000r/min. The rear end of the drill box spindle adopts American DEUBLIN rotary joint.
