TMK2280 Deep Hole Cylinder Boring And Honing Compound Machine

Short Description:

The machine is a kind of high efficiency, high precision, high automation deep hole boring and honing compound equipment. It is used for boring and honing cylindrical workpiece.

In the process of machining, the workpiece rotates and the cutting tool does not rotate.

The cutting oil for boring and honing is different. The machine tool is equipped with two sets of oil supply system and oil tank. When the two processing methods are converted, they need to be switched to their respective oil circuits.

Boring and honing share the same cutting tool tube.

Function Description

2.1 Boring
By means of push boring, the cutting oil enters the inner hole of the tool tube from the end of it, and then reaches the cutting edge.
One end of the workpiece is supported by a manual four jaw chuck, the other end is supported by a steady rest, and the middle of the workpiece is supported by a support jack.
The chip removal device is placed at the left and right ends of the workpiece to send the chip into the chip receiving tank, and the cutting oil directly returns to the boring oil tank.
The ball screw installed on the bed is used to drive the cutting tool to move in Z direction.
When boring, the feeding saddle and the vibration damper steady move on the casting guide way.

2.2 Honing
vibration damper steady of boring move to the rightmost end of the machine, loosen the boring tube by these vibration damper steady and fix the boring tube on the larger vibration damper steady, now the boring tube become honing tube and larger vibration damper steady become the feeding saddle of honing; install the vibration damper steady of honing tube on the machine; install the hydraulic expansion and contraction device of honing head on the left end of the honing tube, and then install the honing head. The connection of the honing head is universal connection.
Remove the chip box on the oil tank, and put the honing recycle oil tank directly under the chip removal device, so that the honing oil can be sent to the honing oil tank through the pump on the recycle oil tank for recycling.
In honing, the servo motor drives the rack and pinion mechanism to realize the movement of feeding saddle of honing on the linear guide way.
