1.3. 3 Machine tool control system
Control System: SIEMENS-808D
X-axis: Control the lateral movement of the worktable, and the servo motor drives the ball screw through the servo reducer.
Z-axis: The cutter feeds longitudinally, and the servo motor drives the rack and pinion mechanism through the reduction mechanism.
1.3. 7 Oil Pressure head 
Used for tool guidance, tool oil supply, tool bar support.
The hydraulic oil cylinder controls the overall axial movement of the oil feeder, and is used for tightening and loosening the working parts..
A tool bar support sleeve is installed at the right end of the oil feeder, which is used to support the tool bar.
A guide sleeve is installed at the left end of the oil feeder for guiding the tool.

1.3. 9 Tool Bar Support
For supporting the knife bar;
It adopts a high-rigidity integral structure, and is equipped with a support sleeve, which can absorb the impact, jitter, etc. generated during processing.
The automatic hanging and pulling mechanism is installed. When the tool is withdrawn, the feed pallet can automatically pull the tool bar bracket back to the initial position.

1.3. 10 Cooling system:
It is mainly composed of cooling pump, chip receiving box, oil tank, etc. to provide enough cutting oil for deep hole machining.
On-ground fuel tank, the fuel tank is fully welded with high-quality steel plate.
Install a telescopic protective cover between the chip boxes on the fuel tank to cover the fuel tank and prevent sundries from falling into the fuel tank.
The pressure, liquid level, oil temperature and flow rate of cutting oil can be digitally displayed on the control station.
