Machining is carried out through traditional processes such as turning, milling, grinding, CNC, wire cutting, electrical discharge, boring, etc., to process the raw materials into precise Machining parts that meet the requirements of the drawings. The highest dimensional accuracy can reach ±0.0005mm, and the surface roughness can reach Ra0.02μm. It is widely used in various industries. Sanluo Precision focuses on precision machinery, CNC, metals, titanium alloys, semiconductor CNC precision machining, and has complete high-precision equipment, professional technical teams and strict inspection systems. It can complete the processing of complex structures, high-precision tolerances and special materials, especially in areas such as grinding, Machining boring, titanium machined parts, etc., with mature experience. Its services cover aerospace, medical, automotive, electronics, semiconductor and other fields, and adhere to quality and technology as the core, providing customers with one-stop precision machining services from R&D prototyping to batch production.
Sanluo Precision Company has precision CNC machining processes covering turning, milling, drilling, and grinding: Turning can complete external round, internal hole, end face, thread, and slot, with diameters ranging from φ3 to 300mm, precision at IT1–IT9 level (±0.002 to 0.1mm), surface roughness Ra0.1 to 1.3μm; Milling can process planes, steps, slots, contours and cavities, with dimensions ranging approximately from 0.50 to 300mm, precision controlled within ±0.002 to 0.02mm; Drilling has diameters ranging from φ0.03 to 100mm, depth ≤ 500mm, positional accuracy approximately ±0.005mm, and verticality 0.01mm. External and internal circle grinding, plane grinding can achieve precision at IT1–IT7 level, roundness 0.002mm, surface roughness Ra0.1μm, and are supplemented by special processes such as wire cutting and electro-discharge machining, providing a solid process foundation for high-demand CNC machining parts.
Sanluo Precision, as a professional manufacturer and supplier of Machining parts, is more skilled at processing complex, irregular, and difficult parts compared to regular requirements for parts. We can produce a variety of products in batches: shaft parts such as smooth shafts, stepped shafts, spline shafts, eccentric shafts, with diameters ranging from φ0.1 to 150mm and lengths not exceeding 800mm, concentricity of 0.002mm and runout of 0.003mm; disc and sleeve parts including flanges, gear blanks, pulleys, shaft sleeves, etc., with outer diameters ranging from φ0.20 to 300mm, end face flatness of 0.005mm, and hole shaft concentricity of 0.003mm; box body parts such as pump bodies, valve bodies, reducer housings, motor housings, etc., with position accuracy of the hole system of 0.01mm, flatness of 0.005mm, and range of threaded holes M0.4 to M24; plate parts such as supports, connection plates, panels, with thickness ranging from 0.3 to 50mm, flatness of 0.001mm, and hole position accuracy of ±0.01mm. At the same time, we can also process fork frames, irregular parts, and other complex structural components with multiple holes and multiple surfaces, providing customers with a wide range of precision machining parts.
The machining parts can be applied to a wide variety of materials, and the heat treatment and surface treatment processes are very complex. After a long period of selection and optimization, we have established high-quality supply and support that meets the needs of industry customers. Sanluo Precision's turning machining and CNC machining factories can handle various black metals, non-ferrous metals and engineering plastics: black metals include carbon steel Q235, 45#, alloy steel 40Cr, 42CrMo, stainless steel 304, 316L, cast iron HT200, QT400, etc., with hardness ranging from HB150 to HRC60; non-ferrous metals cover aluminum alloy 6061, 7075, copper alloy H62, C36000 and titanium alloy TC4; engineering plastics include PA6, PTFE, POM, bakelite, etc., and special tools and processes can be configured for special materials such as tungsten steel, ceramics, and graphite. We also provide heat treatment such as quenching, nitriding, carburizing, and surface treatment such as galvanizing, nickel plating, anodizing, and spraying, so that CNC parts are more in line with the requirements of the end application conditions in terms of strength, wear resistance, and corrosion resistance.
Without a comprehensive after-sales service and rapid response capability, even the best equipment is difficult to gain more customer trust. Sanluo Precision's customized services cover everything from samples to batches. They can complete sample production within 3 to 5 days and start small-scale trial production after the first piece is trial-assembled and performance tested. The automated production line supports monthly production of tens of thousands of pieces and annual production of over a million pieces, ensuring stable supply and cost advantages. Quality inspection uses automatic three-coordinate measuring machines, image analyzers, tool microscopes, high-power microscopes, stereoscopic microscopes, roughness meters, etc. for full inspection of the first piece and process sampling. The CPK is ≥ 1.33, and the comprehensive pass rate is approximately 99%. They also provide complete packaging and delivery services. In China, they can be delivered within 24 to 48 hours. Relying on 7×24-hour technical support, on-site services, and a rapid problem-solving mechanism, they ensure the timely delivery to customers. The company has provided customized services for enterprises such as Huawei, BYD and Foxconn. With its comprehensive advantages in speed, quality, cost and service, it has become a globally recognized partner recognized by the market.
