Precision slot boring machine for pipe expander tube expander

Precision slot boring machine for pipe expander tube expander

The main working principle is to adopt the eccentric structure of the tool bar and the spiral groove reversing structure, and the sliding pin set in the spiral groove drives the tool bar to rotate radial to the set Angle, so as to lift the tool head to complete a slotting process. The tool has the advantages of uniform and smooth grooving depth, stable performance, high strength and long service life. It is especially suitable for grooving belt machining with multiple grooves, high coaxiality requirement or wide grooving belt and high grooving strength. It also has good performance on tube plates with higher hardness such as stainless steel. It has been welcomed by foreign enterprises and joint ventures, and is the best choice to replace imported tools.

Advantages: high strength, high precision, good versatility. The position and depth of the slot can be easily obtained by adjusting the adjusting nut, which is very convenient; When used for multi-slot cutting, the depth between the slots is exactly the same. The hole size of the same model is large, E1 10mm-32mm, E2 38mm-80mm, just by replacing the positioning head and tool rod can be processed for different holes.
