Hole boring process | Chips go out through workpiece’s cored hole. |
2.Main components
Machine base, worktable, and other basic parts | l HT300 iron, resin sand precise casting. l Twice timing treatment, high rigidity and stability. |
Tooling infeed system (Z-axis) | Adopts the servo motor driving the T type leading screw through the reducer structure. The speed is adjustable(stepless). |
Drill bar rest | 1 group, supporting the drill bar. |
Coolant system | To supply the oil for the tooling, consist of oil tank and 3 groups high press pumps. |
Oil pressure head | l The oil pressure head is used for cutter tooling guiding, oil supplying, supporting. l The oil pressure head is driven by ordinary motor to make axial movement. l The oil pressure head spindle can be pushed out and retracted under the control of the hydraulic system. l The oil pressure head can be automatically locked on the machine bed by the hydraulic pressure plate. |
