Ball Valve / Hydraulic T-Piece

Descripción

A Korean manufacturer of hydraulic components and fittings was looking for a more efficient and safer deburring solution for the crossbore of a ball valve. The goal was to automate the process if possible. Up to this date, workmen removed the burrs of the bore edge elaborately by hand with a brush.

Application details

Application details

  • Cross bore / lateral bore: Ø10.4 mm
  • Main bore: Ø10.4 mm
  • Material: SS316
  • Machine: DOOSAN CNC Center

Proposed solution

Proposed solution

The deburring of crossbores with bore-Ø-ratio of 1:1 represented a particular challenge for HEULE. The solutions that were available so far could not cope with the extreme sloping of a 1:1 bore. A complete new approach was needed. HEULE found the answer to the problem by making use of new machine capabilities on one hand and by developing a special version of the COFA tool (COFA-X) on the other hand. Combining the two elements led to the success.

Machining parameters:

  • Speed: 10 m/min
  • Feed: 0.06 mm/U
  • Coolant: external coolant

Customer benefits

Customer benefits

The fact that the deburring could be carried out in an automated process together with the considerably improved reliabilty resulted in significant savings.

The images in the top row show the bore before deburring and in the bottom row the result after deburring by COFA-X .

The successful pilot project is followed by a number of similar T pieces.
