TSK2280 CNC deep hole drilling and boring machine

The boring method of this machine is push boring with forward chip removal, which is granted by the oiler and delivered directly to the cutting zone through a special oil pipe. Machining is done by chuck and top plate clamping, with the workpiece rotating and the boring bar doing Z-feed motion.

Main parameters of the machine

TS21300 is a heavy-duty deep hole machining machine, which can complete the drilling, boring and nesting of deep holes of large-diameter heavy parts. It is suitable for the processing of large oil cylinder, high-pressure boiler tube, cast pipe mold, wind power spindle, ship transmission shaft and nuclear power tube. The machine adopts high and low bed layout, the workpiece bed and cooling oil tank are installed lower than the drag plate bed, which meets the requirements of large diameter workpiece clamping and coolant reflux circulation, meanwhile, the center height of the drag plate bed is lower, which guarantees the stability of feeding. The machine is equipped with a drilling rod box, which can be selected according to the actual processing condition of the workpiece, and the drilling rod can be rotated or fixed. It is a powerful heavy-duty deep hole machining equipment integrating drilling, boring, nesting and other deep hole machining functions.
