Drill depth: 500mm (1000mm optional)

Hole Diameter 3-25mm

Processing Accuracy

Straightness: 1mm/1000mm (every 1000mm, 1mm tolerance)

Roughness: Ra0.8~3.2um

Deep hole accuracy: IT7~IT11

Description of ZKB2103A Economical type deep hole gun drilling machine

ZKB2103A Economical type deep hole gun drilling machine is used for drilling three or two coordinate holes deep-hole machining equipment with properties of high efficiency, high accuracy and high automation. So it is also called three coordinate deep hole gun drilling machine.

It adopts external-chip removing method (gun drill method) through one continues drilling, it can instead of traditional drilling, expanding and reaming procedure and arrive the machine accuracy and surface roughness requirement in one time. The deep hole accuracy is IT7-IT10, roughness is Ra3.2-Ra0.04 um, the center straight line is less than 0.05mm every 1000mm.

It is controlled by CNC system with function of both single action and automatic recycling. So that it can not only meet the requirements of small batch, but also can meet large batch.

The machine can drill through hole, blind hole and step hole. It can be widely used in the industry of automobile and motorcycle, mould, military and aeronautics.

Workpiece Processing Procedure

1. Fix the workpiece on the working table.

2. Pneumatic system control guide suite of the guide frame.

3. Start the cooling system high pressure pump group.

4. Start the drilling bar box, drive the driller rotary.

5. Z axis infeed system drive driller infeed.

6. After drilling to the setted position, driller return, coolant stop, sealed guide suite loose.

7. X, Y axis move to the next drilling position, repeat 2 to 7.

2~7 steps are completed by manual, position display by digital meter
