T22100 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.
