Manufacturing of microparts with micro-turning and micro-drilling


BUTE

IONTO-COMED Hungary Ltd.

Yes

The company searched BUTE, that it would like to produce microparts at the University. The problem was that we had to produce very small pieces. The biggest diameter of parts was 1.6 mm, and the length was 4 mm. We had to do two bores in the pieces. One of bores was 0.5 mm, and the other one was 0.7 mm. And we needed to keep the serious tolerance, for example concentricity.
The University was dealing with similar workpieces. The our tasks were the choice of tools, determination of technology and definition of proper manufacture parameters.

Precipart Ltd.

Yes

The precision workpieces manufacturer Precipart Ltd. is producing the optical component. This company wanted to manufacture Frenel lenses to embossing calender. This is a new technology in the polymer industry. The technology is very difficult therefore the company connected the Budapest University of Technology and Economics (Faculty of Manufacturing Engineering). The University was dealing with similar workpieces, so we began to develop the mould tools. The tasks were the choice of tools, determination of technology and definition of manufacturing parameters.
