Hole boring process

Chips go out through workpiece’s cored hole.

Machine base, worktable, and other basic parts

HT300 iron, resin sand precise casting.

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

The oil pressure head is used for cutter tooling guiding, oil supplying, supporting.
The oil pressure head is driven by ordinary motor to make axial movement.
The oil pressure head spindle can be pushed out and retracted under the control of the hydraulic system.
The oil pressure head can be automatically locked on the machine bed by the hydraulic pressure plate.
