Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
High-Speed Swiss Turning<\/strong><\/td>\nUsing Swiss-type lathes to produce long, slender, or small-diameter brass parts like pins, screws, and shafts.<\/td>\nExtremely fast cycle times for high-volume orders (10,000+ pcs) with consistent precision.<\/td>\n<\/tr>\n
Precision Knurling<\/strong><\/td>\nApplying diamond or straight knurl patterns to brass surfaces for grip or press-fit inserts.<\/td>\nWe achieve crisp, clean knurls without crushing the part, essential for threaded inserts.<\/td>\n<\/tr>\n
Complex Mill-Turn<\/strong><\/td>\nCreating non-cylindrical features on brass fittings (e.g., hex flats, cross holes) in a single operation.<\/td>\nEnsures perfect alignment of features and reduces handling costs.<\/td>\n<\/tr>\n
Cosmetic Polishing<\/strong><\/td>\nPost-machining polishing or tumbling to remove tool marks and enhance the natural gold luster.<\/td>\nDelivers “jewelry-grade” finishes for consumer-facing decorative hardware.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Brass<\/h3>\n

Chip Control:<\/strong>
\nBrass (especially C36000) produces small, granular chips. While this prevents tangling, it requires excellent flushing in deep holes to prevent chip packing and drill breakage.<\/p>\n

Tooling Strategy:<\/strong>
\nBrass is abrasive but soft. We can use standard HSS tools, but Carbide allows for much higher speeds. Tools are kept dedicated to brass to avoid contamination from harder metals.<\/p>\n

Workholding Care:<\/strong>
\nBrass is relatively soft and can be easily dented or deformed. We use collet chucks or soft jaws machined to the part’s profile to distribute clamping force evenly.<\/p>\n

Coolant Use:<\/strong>
\nBrass can often be machined dry, but we use coolant for high-speed operations to control thermal expansion and wash away the fine chips from the cutting zone.<\/p>\n<\/div>\n

Primary Application Industries<\/h3>\n

Plumbing & Fluid Control<\/strong>
\nKey Parts:<\/em> Valves, pipe fittings, nozzles, hose barbs.
\nWhy Brass:<\/em> Excellent corrosion resistance in water and low magnetic permeability. It seals well.<\/p>\n

Electronics & Electrical<\/strong>
\nKey Parts:<\/em> Connector bodies, terminals, standoffs, contact pins.
\nWhy Brass:<\/em> Good electrical conductivity and ease of soldering\/plating.<\/p>\n

Consumer Goods & Decor<\/strong>
\nKey Parts:<\/em> Door handles, luxury pen components, musical instrument parts.
\nWhy Brass:<\/em> The premium golden aesthetic and acoustic properties make it ideal for high-end goods.<\/p>\n

Automotive<\/strong>
\nKey Parts:<\/em> Sensors housings, threaded inserts for plastic manifolds.
\nWhy Brass:<\/em> Non-sparking properties and resistance to corrosion from fuels and oils.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
