Application:
The machines of that group have been designed to clean medium and big castings made of iron and steel and also steel structures of dimensions and weight within the limits indicated in the technical specifications below. Cleaning is effected in a tight chamber by means of shot blasts ejected by projecting rotors whereas the hardly accessible cavities are re-cleaned by the APR-600 pneumatic apparatus which is added to some of machines of that group.
Advantages:
The OWK-3,2, OWK-3,2/P and OWK-5 shot blasting machines are equipped in their own hoisting equipment, whereas the OWK-1- machine has been designed to operate with a crane which eliminates labour-consuming activities connected with suspending castings. After machines of that group are loaded, shot blasting goes on according to an automatic cycle so operation of the machines is much simpler.
