Brass Components & Hardware Polishing
Bright, uniform finishing for brass parts, fittings and hardware
Brass parts are polished on a magnetic polishing machine: stainless steel pins circulating in a water and brightener bath deburr threads and cross-holes, remove machining residue and brighten the whole batch in roughly 5 to 15 minutes.
Brass machining leaves fine, clingy burrs on threads and hole intersections, and the surface tarnishes and loads buffing wheels quickly. Magnetic pin polishing addresses both at once — mechanical deburring plus brightening, with no wheel dressing and no operator-to-operator variation.
Precinova assembles and tests these machines in Saha, Ambala (Haryana), and supports installation, training and consumables across India.

Brass parts this suits
Common brass work in Indian hardware and engineering clusters maps directly onto the process:
- Threaded fittings, nipples, adapters and cable glands
- Valve bodies and components with internal passages
- Sanitary and hardware items needing uniform brightness
- Turned inserts, terminals and electrical components in bulk
- Decorative brass trim and fittings before lacquering or plating
Deburring threads without spoiling them
Thread crests are exactly where hand deburring goes wrong. Because the pins are loose media at low pressure, they clear the tapping burr and the swarf sitting in the root while leaving the thread form intact — parts gauge the same before and after.
The same cycle flushes machining oil and fine chips from internal passages, which matters for valves and fittings that must be clean at assembly.
Brightness and pre-plating preparation
Brightener dosed into the water lifts the surface to an even, clean shine and slows tarnish during handling. For parts going to nickel or chrome plating, the cycle gives the plater a uniform base, which reduces rework from patchy coverage.
For precision-machined brass components, the same cycle reaches threads, cross-holes and internal passages while producing a bright, uniform surface ready for inspection, plating or assembly.
Sizing and quoting
Size by the kilograms of brass you finish per shift. Send part drawings or samples, material grade, daily volume and the finish you need; we quote the machine, starting pin quantity and brightener landed in India with GST, including installation and operator training.

Frequently asked questions
Can brass be polished in a magnetic polishing machine?
Yes. Brass is one of the most common materials for the process — the pins deburr threads and holes, remove machining residue and brighten the surface across a whole batch.
Will it damage brass threads?
No. The pins remove the tapping burr and swarf at low pressure while leaving the thread form intact, so parts still gauge correctly after the cycle.
Is this suitable before plating brass parts?
Yes. The cycle leaves a clean, uniform surface, which gives platers a consistent base and reduces patchy coverage and rework.
Do you supply brass polishing machines across India?
Yes. Precinova Systems Private Limited invoices in India with GST and supplies, installs and services machines nationwide from Ambala, Haryana.
