SZ series horizontal double-spindle CNC deep hole drilling machine
SZ series horizontal double-spindle CNC deep hole drilling machine adopts gun drill and BTA drill to complete deep hole drilling,and the drilling surface roughness is Ra3.2 ~ Ra1.6.
It is mainly used for deep hole drilling of large thick tube sheet in various heat exchangers, pressure vessels, petroleum, chemical, nuclear and other fields.

Deep hole processing

Tube sheet-Heat Exchanger
1.The bed, column, worktable and bending plate are made of high-quality cast iron, with stable accuracy and strong seismic resistance after aging treatment;
2.Two spindles working at the same time, and the efficiency nearly doubled compared to a single spindle. The distance between the two spindles can be adjusted to meet the requirements of different hole distances;
3.The Siemens 828D CNC system can compensate the positioning accuracy of each axis and further improve the positioning accuracy;
4.With a variety of detection functions: ① X/Y axes are equipped with grating ruler ②Spindle feed torque detection ③Spindle motor torque detection ④ Flow detection ⑤Pressure detection ⑥Liquid level detection ⑦Temperature detection.
5.The horizontal deep-hole drilling machine is equipped with linear guide rail pair, ball screw pair, servo motor and its driver, planetary reducer, internal cooling joint, numerical control system, hydraulic pump, valve and other key components, all of which are well-known brands at home and abroad, so the machine tool has very high reliability, few failures and high start-up rate.
