China T21100 Deep Hole Drilling Boring Machine

T21100
Deep hole drilling and boring machine
Usage of the machine: the machine is a special equipment for drilling and boring deep hole of cylindrical workpieces. While boring, the oil supplied from the oil pressure head take the metal chips from the cutting area to the lantern and chip converyer in the front of the headstock, and drilling adopt internal metal chips remving method (BTA method), the oil supplied from oil pressure head remove the chips from the cutting area to the chips receiver in the back of the machine through the innner hole of the drilling tube.
The bed of the machine is rectangle quenched guide way which has high antiwear capability, the feed lead screw is installed in the middle of the guide way. The clamp workpiece of the oil pressure head adopt servo motor so it is reliable and safe. The spindle of the oil pressure head has high concentricity with the spindle of the headstock. And the change of the guide bush is also convenient.
This is a easy operating, high efficiency and environment protective deep hole boring machine.
