Features :

7140B CNC Horizontal Fine Boring Machine is used for boring the single hole, stepped hole, multi-hole, hole group, the circular hole and the slot.

It also can be used for turning the face, counter bore the hole and chamfer the corner.

The bored parts are provided with the higher precision in the size, position and shape, also the required surface roughness.

It is available for the fine machining of hole in the large production batch.

1. The machine can move longitudinally with the higher precision for positioning.

It is specially suitable for boring the deep holes with high precision

2. The machine is controlled by CNC system, with high reliability, convenient programming and flexible operation.

3. With rigid frame structure, harden and fine ground V-type and plane guideway.
