Our core is CNC turning & milling and Swiss sliding-head turning of brass, copper and aluminium — backed by managed hot forging. Every part is machined, finished and inspected in-house in Jamnagar.
Brassland is a precision brass manufacturer in Jamnagar, India — the world’s brass capital — running 79+ CNC machines under one roof. Our core processes are CNC turning & milling and Swiss-type sliding-head turning of brass, copper and aluminium — finished complete and held to tight tolerances. For complex, high-volume shapes such as valve bodies and manifolds we add managed hot forging, produced by a dedicated partner to our dies and then machined and inspected in-house. Whichever route your part takes, you deal with one supplier accountable for design, machining, finishing and quality.

CNC and Swiss turning start from drawn brass rod to EN 12164. The temper designation determines hardness and machinability:
R360 — soft, most ductile, easiest chip breaking. Standard for general CNC components.
R430 — harder, higher strength, tighter dimensional stability. Used for close-tolerance components and Swiss work.
Brass machinability ratings (CW617N = 100%) reflect the ability to form short, broken chips at high cutting speeds. Long stringy chips are dangerous in high-speed Swiss turning — they wrap around tooling and cause breakage.
Lead (Pb) acts as an internal lubricant and chip-breaker in brass. Lead-free alloys (CW724R, CuZn37) require optimised tool geometry and cutting parameters to achieve acceptable chip form.
For pressure equipment (PED 2014/68/EU), potable water approval (WRAS, NSF 61), or automotive (PPAP), material traceability from bar stock to finished part is mandatory.
Brassland supplies EN 10204 Type 3.1 certificates on all bar stock, with heat number traceability maintained through production to finished component inspection records.
Our core is CNC turning & milling and Swiss-type sliding-head turning of brass, copper and aluminium, backed by managed hot forging of brass. All machining, finishing and inspection is done in-house in Jamnagar.
79+ CNC machines, including 28+ Swiss-type sliding-head machines from Tsugami and Star (Japan), backed by CNC turning, turn-mill and rotary-transfer centres.
Small, slender, high-precision parts in volume suit Swiss turning (Ø2–32 mm). Larger turned-and-milled parts suit CNC machining (Ø6–150 mm). Complex 3D shapes such as valve bodies in high volume suit hot forging followed by CNC finishing.
No. Hot forging is produced by a dedicated forging partner working to Brassland’s dies and quality plan; Brassland machines, finishes and inspects every forged part in-house. Forging is brass only.
Swiss turning holds IT4–IT6 (±0.005 mm achievable); CNC machining holds IT6–IT8 (±0.02–0.05 mm). Brassland is ISO 9001, ISO 14001 and ISO 45001 certified and supplies EN 10204 3.1 material certificates.
Brassland runs precision CNC and Swiss turning in-house in Jamnagar — the global centre of brass manufacturing — backed by managed hot forging, with all machining, finishing and inspection done under our own roof.
Discuss Your Part Alloy DatasheetsProcess parameters, tolerances and tooling guidance on this page are drawn from the publishing bodies and tool manufacturers below. For production-critical specification, validate the parameters against your machine, tooling vendor and material supplier — the values shown are starting points typical of free-machining brass under standard CNC and forging conditions.
Last reviewed: June 2026. Values on this page are typical starting points across CNC turning, Swiss turning and hot forging of free-machining brass (CW617N/CW614N); confirm against the relevant standard, your tooling and material supplier. For close-tolerance parts, validate via first-article inspection (FAI) before scale production.
