SZ25/2,SZ40/2 CNC horizontal deep hole drilling machineMachine tool use:This machine is mainly used in petroleum, chemical, pharmaceutical, power station, nuclear power plants and other industries of shell and tube for heat exchanger tube plate hole machining, maximum machining diameter 4000mm workpiece (need to flip 180 degrees) maximum drilling depth 800mm. The machine tool has high efficiency and good accuracy, the surface roughness can reach Ra6.3 ~ Ra3.2, and the aperture is IT9 ~ IT10, and the linearity of the hole is 0.1mm/100mm.This machine can use the outer chip or chip single gun drill BTA drill, double spindle can work at the same time (adjustable spacing). Using programming software to convert DXF format drawings into NC parts program. Optimizing drilling sequence, improving drilling efficiency. Machine tools with a variety of safety and automatic protection, automatic safety monitoring can be realized.Machine tool structure and configuration:1.This machine is mainly longitudinal slipway, a vertical slide, double spindle feed sliding table, work station and plate bending, hydraulic system, cooling system, automatic lubrication system, electrical system, row chip etc..2.This machine is a horizontal deep hole drilling machine. Machine tools are the basis of pieces of bed, column, table and a bent plate, etc. are the high quality iron castings, with aging treatment, precision and stability, seismic. Bed is arranged on the upper surface of the longitudinal sliding table for bearing the column longitudinal (x) to the mobile, is mounted on the upright post; a vertical sliding bearing spindle feed slider for vertical (y) to the mobile; spindle feed slide spindle is driven by a feed (z) to the movement.3.Machine& acute;s x, y, Z axis are imported roller linear guide rail pair oriented, with high bearing ability and excellent dynamic response performance and gapless. High precision motion. The three axes are driven by a pre loaded ball screw, which is driven by the serv
