T21100 Deep Hole Drilling and Boring Machine:

The usage of the machine,the machine is special equipment for machining deep cylindrical hole of workpieces.It suitable for boring the cylindrical workpiece.When boring the hole,the oil is supply from the guide carriage,and take the chips from the cutting area to the equipment of chip conveying on the headstock. The drilling method is the internal removal chip(BTA method) when drill.The oil is supply from the guide carriage,and take the chips from the cutting area to the equipment of chip conveying in the back of machine.

The machine is controlled by PLC, the reciprocating movements of guide carriage and feeding carriage are controlled by the servo motor.The drive is made by the racks in the two to ensure long movement feeding transmission accuracy and rigidity requirements. The protection on the two sides of the bed body and the use of the ground oil tank structure improve machine tool environment. The machine can be equipped with two automatic or manual expansion efficient tool,it greatly improves the machining efficiency.
