Heavy-duty CNC Horizontal Deep Hole Drilling and Boring Machine
DBK-500 DBK-500A
Machine Summary
DBK-500/DBK-500A CNC deep hole drilling and boring machine is mainly for the processing of cylindrical workpiece. The tool is kept rotating and feeding, this machine can perform the process of drilling, boring ,expanding and roller burnishing, etc. The machine is equipped with CNC system. Besides machining through-hole, it can also process step hole and blind hole, etc. The machine tool is suitable for production of special cylinder, coal cylinder, hydraulic machinery, high pressure boiler tube, petroleum, military, electrics and airspace, etc.
Performance and Features
1. The headstock spindle is driven by large power DC motor, using multi-gear speed change and stepless speed regulation. The process adopts the mode of workpiece rotating and tools feeding, the coolant is supplied by the oil feeder or through the end of boring bar, the chip is pushed out by the coolant pressure.
2. The headstock part is equipped with three-jaw or four-jaw chuck, the oil feeder clamps the workpiece by servo motor.
3. The oil feeder can be moved and positioned along the bed body, and maintaining the constant clamping force to the workpiece. The oil feeder adopts the principal axis structure which improves the load capacity and rotation accuracy. The hydraulic system has a good control when clamping and fixing the workpiece, which has a high stability and good precision.
4. The bed body is made of high strength cast iron, which ensures the machine with enough rigidity. The guide rail is treated by hardening technology and has the excellent wear-resistance and high precision retaining ability. All the operation parameters are shown by meter display, the workpiece clamping and the operation is very safe, rapid and stable.
