A.V. Luikov Institute of Heat and Mass Transfer of the NAS of Belarus offers consumers services for the technological cleaning of parts of high-precision mechanisms from burrs, microparticles and microliquids under an outsourcing agreement or subcontract and is looking for partners to conclude a manufacturing agreement.

At present, for all branches of mechanical engineering, the problem of technological cleaning of parts of high-precision mechanisms from burrs, microparticles and microliquids is relevant. The main processing methods that do not lead to additional micro-pollutions are electrochemical and thermal pulse. However, the electrochemical method can only remove impurities and defects on metals, while thermal pulse processing is applicable to metals, plastics, ceramics and composite materials and improves the quality of products, their working life, safety and increase the competitiveness of products in the market.

The A.V. Lykov Institute of Heat and Mass Transfer of the NAS of Belarus has developed an installation for finishing thermal pulse processing of metals and plastics, in which burrs and process impurities are removed due to short-term (up to 20 ms) high-density thermal exposure.

Processing of parts is carried out inside a cylindrical chamber by generating a thermal pulse in it by an explosion of a combustible gas mixture. To intensify the processes of heat exchange between the part and the products of combustion, the combustion of fuel occurs in the detonation mode. The removal of combustion products is carried out in a hot state, which prevents the deposition of oxides and removed materials on the treated surfaces. The control system registers the pressure in the chamber during processing and records the measurements with a digital oscilloscope.

Technical characteristics of the installation:

dimensions	750х750х2600 mm
weight	3200 kg
processing chamber cylinder size	200х200 mm
processing chamber volume before locking	25,1 liters
processing chamber volume after locking	6,3 liters
maximum pressure	600 atm
exposure time	20 ms
process temperature	2500–3500 °С

Thermal pulse processing makes it possible to create energy- and material-saving, environmentally friendly technological processes, including through the use of economical and environmentally friendly quenching medium, providing a significant reduction in residual thermal stresses and deformations of products.

Gas-pulse processing improves mechanical, technological and operational properties structural and tool steels, titanium and aluminum alloys, plastics.
