Super Large Deep Hole Boring Machine For Hydraulic Cylinder
DB-2000A
Performance and Features
*DB-2000A heavy duty deep hole boring machine is specially for processing of large and heavy duty cylindrical workpiece.
*The machine body has the strong rigidity and good precision retaining ability. The spindle adopts three shifts with stepless speed regulation (high, neutral, low) in a wide range.
*Feed system is driven by large power AC servo motor, which meets the different processing demands.
*The oil feeder clamps the workpiece by mechanical device, which is very safe and reliable.
*The machine can perform boring of heavy duty components in a large diameter. When boring, the cutting liquid is supplied to cutting area through boring bar, and the chip is discharged forward to headstock end. When trepanning, the external chip removal mode is used, and the special tool, tool bar and clamping device should be equipped.
*The machine consists of bed body, headstock, oil feeder, feed system, steady rest, workpiece support, boring bar support, feed carriage, cooling system, hydraulic system and electric system, etc.
*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.
Technical Parameters
Packaging & Shipping
*Firstly packed by waterproof cloth and then in wooden case.
*Few parts may need to be taken down and be packed in wooden case.
*According to customer's different require, wo can adopt different packaging.
*About some heavy-duty and super large machine tools, we can need disconnect the machine, then separate packing.
*Whether CNC deep hole honing machine or CNC deep hole drilling and boring machine or CNC deep hole skiving roller burnishing machine, we all use the same standard Packagings.
