Practical accessory for CNC walking machine - boring bar sleeve

When in a large O D. When a small diameter boring bar is needed internally, a boring bar sleeve is practical and necessary to reduce the outer diameter of the boring bar sleeve, so that the coolant from the turntable will not be deflected by the sleeve, but can enter the hole along the boring bar.

When using a necking design boring bar sleeve, you will find another advantage, which is drilling a hole with a countersunk hole. Here, the boring bar must only extend a sufficient distance to complete the hole, and the neck of the boring bar sleeve can enter the counterbore and provide as much support as possible for the boring bar. The necking function is unique to MTA.

This arrangement allows you to position the boring bar inside the sleeve and the sleeve inside the turret for better results. This choice is very important because sometimes the boring bar works better when clamped at the top; The effect is better when clamped on the side or bottom at other times. In any case, you will always have three rows of clamping (lines formed by two sets of fixing screws and opposite sides of the boring bar sleeve hole).

Heat treatment: The boring bar sleeve undergoes heat treatment to provide you with toughness, wear resistance, and long-term reliability under harsh service conditions.
