Our High-Performance Manufacturing Arsenal

Dongguan SX Technology Co.,Ltd leverages advanced production setups to achieve micro-dimensional accuracy. By employing high-speed Swiss lathes with sliding headstock capabilities, the material is gripped and supported near the guide bushing during the entire machining path, which virtually eliminates structural deflection. This layout is key to producing high L/D (length-to-diameter) ratio shafts and thin-walled parts.

Our facility runs continuous maintenance protocols on all equipment to guarantee sub-micron repeatability. Each Swiss turn-mill station features simultaneous multi-axis toolpaths, live tooling, and sub-spindles, allowing us to perform milling, drilling, cross-tapping, and turning operations in a single operational cycle. This reduces part handling and eliminates tolerance stack-up errors.

Metrology & Quality Assurance Philosophy

“Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better. Therefore, we have been working in this industry unremittingly since 2014 and continue to improve the company's team and production capacity.”

We deploy dedicated quality control personnel alongside automated measuring systems. Our testing equipment includes high-precision Coordinate Measuring Machines (CMM), optical comparators, laser micrometer systems, digital spectrometers for metallurgical verification, and surface profile instruments to measure roughness (Ra values down to 0.2 microns). All output undergoes strict first-article inspections (FAI) and in-process sampling checks to verify tolerances before shipping.

Technical FAQ: CNC Swiss Precision Machining

Technical insights into design, material selection, and process optimization for Swiss machining and casting projects.

What makes Swiss-type CNC machining better than traditional CNC turning? +

Traditional CNC lathes hold the workpiece at one or both ends, meaning long, slender parts can bend under tool pressure. Swiss-type CNC machines feed the bar stock through a guide bushing. The cutting tool operates directly next to the bushing's support point. Because the material does not deflect under force, Swiss machining maintains tight tolerances (up to ±0.002 mm) on very long, thin components.

Which materials are best suited for Swiss CNC micro-machining? +

We machine a wide variety of metals. Standard choices include titanium alloys (Grade 5/Ti-6Al-4V) for biocompatible medical implants and aerospace parts, stainless steel (303, 304, 316L) for corrosion resistance, and brass or copper alloys for high electrical conductivity. We also work with carbon steels, aluminum alloys, and specialized cemented carbides.

What is your typical lead time for custom OEM prototypes and production orders? +

Prototype orders typically take 3 to 7 working days, depending on geometry and finishing needs. Medium to high-volume production orders range between 2 to 4 weeks. If specialized castings or tooling are required, we provide a complete engineering timeline after reviewing the 3D drawings (STEP, IGES, or DWG formats).

How does Dongguan SX Technology Co.,Ltd ensure material traceability? +

Every raw material batch we receive comes with a Mill Test Certificate (MTC) detailing its chemical composition and mechanical properties. We verify this raw stock internally using spectroscopic testers. All parts receive tracking serial numbers throughout the production process to ensure traceability back to the raw material melt batch.

Can you combine investment casting and CNC machining in-house? +

Yes. We specialize in casting-to-machining workflows. For complex, organic shapes, we run lost-wax investment casting using stainless steel or carbon steel. After casting, we machine critical interfaces, bores, and threads using high-precision CNC mills and lathes to meet exact dimensional requirements.

What surface finishing processes do you support? +

To support varying industrial needs, we provide passivation, anodizing (Type II and Type III hardcoat), chemical conversion coating, zinc/nickel plating, electropolishing, bead blasting, powder coating, and heat treatment processes (carburizing, nitriding, quenching, and tempering).
