Maintain processing stability 

Kunshan Tengzhen Precision Machinery Co., Ltd. adopts a highly stable pressure control scheme in the cooling system configuration, ensuring a continuous and smooth cutting process. 

3. Chip Removal System

One of the challenges in deep hole machining is chip removal. Different processes require different chip removal methods: 

Gun drill → Cooling fluid is centrally introduced and chips are discharged externally. 

BTA → External coolant supply and central chip removal 

The optimized chip removal system can prevent chip blockage, tool damage and hole wall scratching, thereby enhancing processing reliability. 

4. Feed Control System

Deep hole machining has extremely high requirements for feed stability, so it is necessary to: 

Stable servo drive 

Precise feed control 

Smooth slides and transmission mechanisms 

These technologies ensure that the cutting tool operates at a constant speed, thereby maintaining the straightness of the holes and the surface quality. 

5. Fixture and Support System

During the processing, the workpiece must remain relatively stable. Therefore, the deep hole equipment is equipped with: 

Adjustable support frame 

Reliable clamping method 

Multiple support mechanisms 

These structures can prevent the workpiece from shaking during the processing, ensuring the accuracy of the hole orientation. 

IV. Applications of Deep Hole Equipment
