What Is Swiss CNC Machining Service?
Swiss CNC machining, also known as Swiss turning or Swiss-type lathing, is a high-precision turning technology originating from the watchmaking industry. It specializes in processing long, slender workpieces by fixing the material with a guide bushing close to the cutting tool—minimizing deflection and vibration during machining. This unique structure enables the process to achieve extremely tight tolerances, making it the preferred solution for manufacturing small-diameter, complex, and high-precision components. Compared with traditional CNC turning, Swiss CNC machining excels in processing parts with high length-to-diameter ratios (such as micro shafts, pins, and precision fasteners), ensuring superior dimensional stability and surface finish.
Bomei’s Swiss CNC Machining Service Advantages
-
Ultra-High Precision: Equipped with high-end Swiss CNC lathes with guide bushing systems, we achieve tolerances as tight as ±0.002mm, easily meeting the strict precision requirements of micro-components and slender parts.
-
Superior Processing of Slender Workpieces: The guide bushing design minimizes workpiece deflection during high-speed rotation, enabling stable processing of parts with length-to-diameter ratios up to 20:1, such as micro shafts, precision needles, and thin-walled sleeves.
-
Integrated Multi-Process Machining: Our Swiss CNC turning centers are equipped with multi-axis (up to 7-axis) driven tools, realizing integrated processing of turning, milling, drilling, tapping, knurling, and polishing in a single setup. This eliminates repeated clamping errors, improves processing efficiency, and ensures consistent quality of complex components.
-
Reliable Quality & Timely Delivery: Adhering to strict quality control standards, we implement full-process inspection for each batch of products. Combined with mature production management experience, we guarantee competitive pricing for small-quantity orders and on-time delivery for mass production, satisfying the diverse needs of global high-end clients.
