Deburring bore holes - Overview

Deburring. Safe and efficient.

HSD deburring tools are used in highly automated processes for deburring of bores. The reasons for automation of deburring are often large quantities, short deburring times, high reproducibility of the result or the rationalization of manual deburring.

Remove the burr where it originates.

HSD tools are used in machining centers, lathes and milling machines, deburring stations or robot-guided in deburring cells. Deburring can be integrated into the process or added as a separate process step.

Typical tasks and areas of application

Bohrungen entgraten

Deburring of:

Several intersecting holes are machined through the main hole with only one deburring tool in one step. All intersecting holes are deburred, even with different diameters.

The smallest tool diameter currently used is about 2mm. This is the diameter of the main hole through which the tool enters. The smallest cross holes to be deburred are in the diameter range around 1mm.

In forward and backward machining by the HSD tool in clockwise and anti-clockwise rotation, all edges of an intersection are deburred.

The cutting force is controlled directly by the pressure. This control by air (e.g. in the deburring station) or coolant (mainly in the machine) enables higher speeds and feeds. The necessary cutting force can be  adjusted optimally.

The cutting edges are flexible supported and are controlled by pressure, i.e. the cutting edges can be “extended” exactly at the cross hole to remove the burr. In addition, for processing the pressure at the cutting edges can be adapted to the burr strength and size to be removed.

The detached burr and existing chips are washed away by the coolant or compressed air flowing out at the cutting edges. This minimizes the influence on the roughness of the workpiece surface. Special cutting edges are used for particularly high surface requirements.

Inquiry - Analysis - Advice - Order

The HSD deburring tools are special tools that are individually adapted and manufactured to the component to be deburred and the process.

The following information will be very helpful in advance:

  • Component drawing, sketch or photo of the location of the burrs to be removed
  • Short hint on the origin of the burr, machining sequence
  • Are there requirements for the chamfer or roughness after deburring?
  • Is a cooling medium or compressed air available? What pressure is on or can be set?
