Company Electrovek-steel offers to purchase at reasonable prices from the manufacturer rolling, castings and forgings made of bronze alloys that have passed qualitative grinding and polishing. The supplier ensures the timely delivery of products to the address set by the client.
Features of grinding and polishing bronze
After most machining transitions, and also after casting, the surface of bronze products requires finishing operations — polishing and polishing. The choice of suitable technology depends on:
- The ultimate hardness of the alloy;
- The chemical composition of bronze;
- Required degree of microporosity of the product;
Most often, grinding is subjected to antifriction bronzes: the products of them work at constant contact loads (for example, in worm gears), and therefore the main operational requirement is to ensure the minimum value of the coefficient of friction. This can only be achieved by thoroughly polishing the contacting surfaces.
For grinding bronze use:
- Carborundum, if brittle, foundry bronzes are treated;
- Corundum, if grinding is used for relatively more viscous bronzes containing silicon and / or aluminum;
- Pastes based on chromium oxide, which before application is applied to conventional grinding wheels.
Buy at an affordable price from the manufacturer of the original forgings, rolled or cast from various bronze alloys that have been polished and polished, offers the company Electrovek-steel. The supplier ensures prompt delivery of products to the point set by the consumer.
For polishing bronze alloys, grinding machines (manual or stationary types) are used for which petal grinding wheels with a grain size of no more than P320 are installed. The process is carried out at relatively small revolutions of the working shaft (no higher than 800… 1000 min -1) to ensure the continuity of the polished surface of the product.
Polishing of bronze blanks / parts is performed on the same equipment, but instead of the petal circles, fabric or felt ones are installed. They provide the best surface quality, with uniform light reflection. The most difficult to grind bronze castings of complex shape. In order to ensure uniform treatment, tumbling equipment is used, and a mixture of zirconium balls and plastic is used as an expendable material.
The company Electrovek-steel offers to purchase at favorable prices from the manufacturer polished semi-finished products, forgings and rolled products from various bronze alloys. Guaranteed compliance with parameters of surface roughness, prompt delivery to the customer of finished products.
