About steel turnings & borings scrap
Turnings and borings are graded on three things: what alloy they are, how much cutting oil or coolant they hold, and whether grades have been mixed. A clean MS swarf bin, drained and free of stainless or aluminium chips, is a saleable feedstock. The same weight of mixed, dripping swarf is a problem material and priced accordingly.
For engineering units in and around Coimbatore and Madurai this is usually a standing arrangement: we place labelled bins at each machine group, collect weekly or on call, weigh at pickup and issue a consolidated statement. That keeps the material segregated at source, which is the only point where segregation is cheap.
Briquetted or compacted swarf is bought at a better rate than loose material because it transports and melts far more efficiently. If you already have a briquetting press, tell us — it changes the quote.
