T2250A Deep Hole Drilling and Boring Machine

T2250A deephole drilling and boring machine is new product which is inovated on the base of our matured deephole drilling boring machine T2250A. According to the length of workpiece, the products adopts two processing technics: it adopts supplying oil by the guide carriage and hydraulic clamping workpiede when the workpiece is short, and adopts supplying oil from the end of oring bar and clamped by four claw chuck. The inovated guide carriage structure have the advantage of heavy loading of the workpiece and high rotate precision. The guideway is treated by quenching so that it has a high rotate precision. The guideway is treated by quenching so that it has a high resistamce of wearing. The surface roughness reaches to 0.4-4.8µm. According to the workpiece, several work style can be choosed:

1.Workpiece rotate, cutting tool rotate and move to-and-fro.

2.Workpiece rotate, cutting tool not rotate only move to-and-fro.

3.Workpiece not rotate, cutting tool rotate and move to-and-fro.
