Steel & Metal Precision Machining Services
1) Overview
We provide steel and metal machining services, covering a wide range of materials such as stainless steel, carbon steel, alloy steel, nickel alloys, copper, aluminum, and titanium.
Capabilities include turning, milling, drilling, boring, grinding, cutting, welding, and precision CNC machining, suitable for fittings, flanges, forgings, bars, plates, and structural parts.
Our machining solutions are widely used in petrochemical, energy, power, shipbuilding, machinery, aerospace, automotive, food & pharmaceutical industries.
Standard / Non-standard / Precision Machining
a) Standard Parts Machining
We provide mass production of standard parts according to GB, DIN, ISO, ANSI, JIS standards, ensuring high interchangeability, short lead time, and stable quality.
Typical products: bolts, nuts, washers, pins, keys, fasteners, bearing sleeves, flanges.
Advantages:
• High-volume production capacity
• Material coverage: stainless steel, carbon steel, alloy steel
• Surface finishes: galvanizing, black oxide, nickel plating, polishing
b) Non-standard Custom Machining
We offer custom machining services for non-standard parts, tailored to customer drawings or samples.
Typical products: large customized flanges, special reducers, valve bodies, non-standard bolts, structural components.
Advantages:
• Flexible order size: prototype, small batch, or mass production
• Wide machining range: micro parts ≤ φ5 mm, heavy parts up to φ1500 mm
• Full-process service: raw material → machining → heat treatment → surface finishing
c) Precision Machining
Equipped with CNC lathes, machining centers, grinding machines, and CMM inspection, we deliver high-precision components for aerospace, energy, medical, and semiconductor industries.
Typical products: turbine blades, hydraulic valve cores, precision bearing sleeves, medical parts, micro-hole components.
