Swiss-Turned Precision Parts
Precision Swiss-turned parts include shafts, threaded inserts, splined components, knurled parts, sleeves, and miniature mechanical components. Swiss lathe processing supports stable concentricity, detailed external features, internal threads, cross holes, and repeatable production for small-diameter parts.
Complex CNC Machined Metal Parts
Complex CNC machined metal parts combine turned surfaces with milled profiles, mounting holes, pockets, flanges, and irregular features. Multi-process machining helps reduce repeated setups while maintaining alignment between cylindrical and non-rotational features.
Engineering Plastic & Prototype Parts
Engineering plastic parts are produced for functional testing, product development, assembly verification, and low-volume applications. CNC machining supports custom holes, slots, internal structures, transparent features, and complex plastic geometries without production tooling.

Supplementary Notes
- CNC Swiss lathes are specialized for slender miniature shaft workpieces with complex stepped and threaded structures. Passivation and electroless nickel plating are ideal processes to fully cover intricate inner and outer tiny features.
- Original surface roughness of raw Swiss turned workpieces without secondary finishing ranges from Ra1.6μm to Ra3.2μm.
- Cost hierarchy: Low < Medium < Medium-High < High
Black Oxide / Passivation < Sandblasting / Brushing / Standard Anodizing < Electroless Nickel / Precision Grinding < Mirror Polishing / Micro-Arc Oxidation / Bright Chrome Plating
When Swiss CNC Turning Is the Right Manufacturing Choice
- Tiny slender shafts, pins and stepped micro parts
- Ultra-tight concentricity & micron-level dimensional tolerances
- Complex features: fine threads, deep small bores, tiny grooves
- Low/medium batches of metal precision hardware (aluminum, steel, stainless steel, brass)

What types of design files do you accept for quotation and manufacturing?
-
We support mainstream 3D CAD formats including STEP, IGES, SolidWorks, UG, CATIA, and PRT files. To offer accurate tolerance evaluation and formal quotes, we highly recommend you to provide complete 2D engineering drawings with marked dimensional tolerances, surface roughness requirements and surface finishing standards. If you only have simple renderings without dimensional data, our engineers will communicate with you to confirm all key parameters before quoting.
-
Is there a minimum order quantity (MOQ) for Swiss turning and CNC machining parts?
-
There is no mandatory minimum order quantity in our factory. We fully support single prototype sample production for new product verification, as well as small-batch and medium-batch customized manufacturing. Whether you only need one test piece or hundreds of finished components, we can arrange independent production lines to match your flexible order demands.
-
What raw materials can be processed with your Swiss lathe equipment?

Can you provide customized surface finishing solutions for machined parts?
-
Yes, we own complete in-house surface treatment workshops without outsourcing all processes. We can customize different finishing technologies according to your functional and aesthetic needs, including mirror polishing, sandblasting, wire drawing, clear/colored hard anodizing, electroless nickel plating, chrome plating, stainless steel passivation, black oxide, electrophoresis, laser marking and silk printing. We can adjust coating thickness, surface roughness and texture to fit your assembly and service environment requirements.
-
What quality inspection equipment and systems do you use to guarantee dimensional precision?

We have passed ISO9001 quality management system certification. Our inspection lab is equipped with CMM three-coordinate measuring machines, 2.5D image measuring instruments, precision micrometers, thread gauges and height gauges. Every batch of finished parts will go through full sampling dimensional inspection, surface roughness testing and coating thickness detection to ensure all indexes meet your drawing
-
How do you protect the confidentiality of my product drawings and project information?
-
We implement multi-layer confidentiality management for all customer design materials. We can sign formal non-disclosure agreements (NDA) with clients before cooperation. Internally, all CAD files are stored in encrypted servers with access authority control; production staff cannot copy or export design data. We prohibit the disclosure of any customer product information to third parties, and we will not display your finished products in public cases without written permission.
