China manual deephole drilling and boring machines company

Product Description

This machine is specially designed for deep hole processing of cylindrical workpiece, it can perform different processing, such as drilling, boring, expanding and roller burnishing, etc. Besides machining through-hole, it can also process step hole and blind hole. The process adopts the mode of workpiece rotating and tools feeding, if necessary the tool can be also rotary. With the workpiece rotating and the tool feeding, the cutting fluid reaches the cutting area by oil supply device or through boring bar end, the chip removal adopts BTA type. When boring, the cutting fluid pushes chips forward out of headstock end. To meet the different processing demand, the machine can be equipped with drilling box, achieving double rotation of workpiece and tools, and the single action is also available. Under the conditions of lower speed rotation of the workpiece, the processing efficiency and quality can be assured. This machine has a wide application according to different processing demand. The machine consists of bed body, headstock, drill box(optional), chuck body, carriage feed system, oil feeder, cooling system, chips removal device, steady rest, hydraulic system, boring bar support, motor device and electrical control system, etc.
