High-Precision CNC Swiss Machined Shafts for Demanding Industries
At Xierge Precision Machinery Co., Ltd., we leverage over 30 years of operational expertise to manufacture premium CNC Swiss Machined Shafts for the automotive, medical, machinery, and home appliance industries. Established in 1990, our company understands that shaft components require exceptional dimensional stability, superior surface finishes, and perfect concentricity to function reliably in high-speed or high-load environments.
Our production facility is heavily equipped with Japanese imported Star CNC Swiss-type lathes. This specialized equipment feeds the bar stock through a guide bushing, allowing the cutting tool to operate precisely near the support point. This method is crucial for machining long, slender, and complex shaft geometries with high length-to-diameter ratios, virtually eliminating deflection, vibration, and "banana" effects. Furthermore, our multi-axis machining centers and precision grinders enable us to complete complex features—such as cross holes, keyways, and micro-threads—in a single setup.
Following our core principle of "Integrity Oriented, Quality Foremost," we exclusively adopt premium raw materials, including stainless steel, alloy steel, and titanium. We apply strict quality inspections using a complete set of testing instruments imported from Japan and Germany, ensuring that every shaft delivers reliable, long-lasting performance. We keep innovating to maintain sound business development and warmly welcome domestic and overseas clients to visit our factory and explore custom OEM/ODM cooperation opportunities.

Payment Methods & Global Logistics Solutions
Secure International Payment Terms:
To facilitate seamless global trade, we offer highly flexible and secure payment options. For mass production orders of CNC machined shafts, we accept standard T/T (Telegraphic Transfer) with a 30% advance deposit and 70% balance before shipment. For large-scale international supply contracts, we are fully capable of processing Irrevocable Letters of Credit (L/C) at sight. For initial prototyping, sample orders, or custom tooling fees, PayPal and Western Union are also available to expedite the process.
Global Logistics & Protective Packaging:
We provide comprehensive end-to-end shipping solutions under FOB, CIF, and DAP Incoterms. For urgent prototypes or small batches, we utilize expedited international couriers such as DHL, FedEx, and UPS. For bulk mass production, we offer highly competitive sea freight (LCL/FCL) and air cargo rates through our trusted global forwarder network. Recognizing that precision shafts are highly susceptible to bending and corrosion during transit, we utilize specialized packaging: each shaft is individually wrapped in VCI (Volatile Corrosion Inhibitor) anti-rust paper, secured in custom rigid cardboard tubes or EPE foam slots, and packed in sturdy export-grade wooden cases to ensure zero deformation upon arrival.
FAQ
Swiss-type CNC lathes feed the bar stock through a guide bushing, allowing the cutting tool to operate directly adjacent to the bushing. This provides continuous support to the workpiece, virtually eliminating deflection. Consequently, we can machine long, slender shafts with high length-to-diameter ratios while maintaining extreme straightness, tight tolerances, and excellent surface finishes—something conventional CNC lathes struggle to achieve without steady rests.
Yes. Our Star CNC Swiss-type lathes are equipped with live tooling and multi-axis capabilities. This allows us to perform axial and radial drilling, milling of flats, and threading operations directly on the machine in a single setup. Because the part does not need to be transferred to a secondary machine, we maintain perfect concentricity and geometric tolerances.
For hardened steel shafts (e.g., HRC 55+), we employ a two-stage process. First, we perform rough turning on the Swiss lathe, leaving a small grinding allowance. After the heat treatment process, we utilize our precision cylindrical grinders to remove the allowance. This ensures the final dimensions, surface roughness (Ra 0.2), and geometric tolerances meet strict automotive and machinery standards without tool chattering.
For medical applications, we highly recommend materials like 17-4PH stainless steel, 316LVM surgical stainless steel, and Titanium Grade 5 (Ti-6Al-4V). These materials offer excellent biocompatibility, high corrosion resistance, and superior mechanical strength. We have mature processing parameters for all these exotic materials.
To manage residual stress, especially in long shafts, we optimize our cutting parameters to reduce heat generation. For highly critical applications, we can incorporate stress-relief annealing processes between rough and finish machining operations. Our imported German and Japanese metrology equipment also allows us to precisely measure and verify straightness post-machining.
Cleanliness is vital for these industries. After machining and deburring, all shafts pass through our dedicated industrial cleaning machines using ultrasonic technology. This process removes all cutting fluids, micro-burrs, and metal dust from threads and cross-holes. They are then immediately vacuum-sealed in a clean environment to maintain pristine condition.
