CNC Deephole Drilling & Boring Machine is suitable for the drilling, boring and rolling processing of all kinds hydraulic oil cylinder, cylinder and other precision tube fittings, especially for the precision processing of step holes. The hole diameter accuracy of machined workpiece can be up to and over IT7~IT8, and the surface roughness reach Ra0.2~0.3 m. The bed adopts welding steel so that it is strong in rigidity. On the double flat guide way, it equipped the rolling linear guide way. So it has high move precision and high abrasion proof. The bed is also the cooling box, so it is strengthen the stability of bed and reduce the shake. It equipped the Germany SIEMENS 802D CNC system (or appoint by customer). It is AC motor for the headstock, tow grade and stepless. The bearing of spindle is high precision FAG bearing and it is strong in rigidity and high precision in rotating. The feeding box adopts AC servo motor, stepless, and it is equipped with high precision ball screw. It adopts the hydraulic elements which is stable in capability made in Taiwan (or appointed by customer). It adopt scraps discharging by spindle, it equipped automatic discharge scrap equipment and it is not leak. It can also equipped high efficiency automatic expand-draw back combined tools. It is an ideal machine for deephole processing with high precision and efficiency.
