Heavy Duty Deep Hole Drilling and Boring Machine for Hydraulic Cylinder
DB-800 DB-800A
Machine Summary:
*DB-800A machine is mainly for processing of heavy duty cylindrical parts, such as drilling, boring, expanding, roller burnishing and trepanning, etc.
*The workpiece is kept slowly rotating, the tool is rapidly rotary while feeding. Besides machining through- hole, it can also process step hole and blind hole.
*This machine is used in a wide range, the process type can be chosen based on the actual demand.
Performance and Features:
*When drilling, the machine adopts BTA internal chip removal type, the oil feeder supplies the cutting liquid to remove the chips out of the end of drill bar. When push-boring, the cutting liquid reaches cutting area through small hole of oil feeder or big hole at the end of boring bar.
*The chip is flushed out of headstock end. When trepanning, the special tool, tool bar and clamping device should be equipped, the chip is discharged by the external removal type.
*This machine is assembled with drill box, which achieves double rotation of workpiece and tool, the single action is also available based on the actual demand. When the workpiece needs a lower rotary speed, the process efficiency and quality can be assured.
*The headstock adopts heavy duty four-jaw chuck to lock the workpiece, the steady rest is for supporting and the oil feeder is for clamping by hydraulic pressure. The oil feeder adopts the principal axis structure which improves the load-capacity and rotation accuracy. The bed body has an excellent rigidity, good wear-resistance and high precision retaining ability. The tool feeding adopts AC servo motor to realize stepless speed regulation. The headstock uses DC motor with stepless speed regulation. The drill box is driven by large power motor, with speed regulating by gear shift.
*The hydraulic system has an accurate control when clamping and fixing the workpiece, which has a high stability and precision. All the operation parameters are shown by meter display, the workpiece clamping and the operation is very safe, rapid and stable. The machine adopts PLC control with human-machine interface, it is easy to be operated.
*DB-800 is equipped with workhead box, but isn't equipped with boring box or drilling box; DB-800A add to boring box or drilling box on the basis of the DB-800, so higher efficiency machining deep hole for cylindrical workpieces.
*The similar machine consists of bed body, headstock, drilling and boring box (optional), chuck body, feed carriage, oil feeder, cooling system, chip removal device, steady rest, hydraulic system, boring bar support, motor and electrical system, etc.
