The chamfered deburring in cross hole is the difficulty of machining

HTT deburring machine tool is a four-axis double-station machine tool, which can process four workpieces at the same time. There is an automatic loading and unloading device to complete the feeding and unloading of workpieces and the conversion of processing stations.

Take a deburring deep hole drill machine tool produced by our company for Volkswagen as an example. The axial aperture and radial aperture of the gear shaft of your workpiece are 15.3mm. The machine tool requires that the burrs at the two intersections should be removed, leaving no debris. In the drilling deburring station, first with carbide twist drill drill four φ3 aperture, and then with a special positive and negative burring tool into the φ3 hole for deburring, two processing units have feed slide, power head composition, drilling deburring completed, and then move the workpiece to blow cutting work.

Machine tool configuration:

1. Drill, deburring imported tool

2. Power head Swiss Schonen

3. Siemens Numerical Control System
