How to process the step hole φ2-φ1.0 in high efficiency?
For such question, GSM company has specially study a special gun drilling machine. And here is the brief introduction of this gun drilling machine:
1. Name: two-spindle deep hole drilling machine ZK2108×4C/300
2. Machine character: it uses the gun drill to process the ejector sleeve with high processing efficiency,good inside hole roughness and high dimensional accuracy. Especially the straightness of entrance hole is good,and the it can control within 0.025mm.
3. In order to finish the processing with a higher efficiency, it drill the workpiece from two ends. For one time clamping, it can process the φ1.0 and φ2.0 hole , which greatly improve the processing efficiency.
4. Automatic feeding mechanism
In order to decrease the operator labor intensity, here we equip with an automatic feeding mechanism. For one time clamping, there are 28 pcs, until finish the processing. Then manually take away the workpiece.
For this deep hole drilling machine, we have gotten a high praise from the customer with high efficiency and low production cost.
