Sanluo, operating as Shenzhen Sanluo Precision Technology Co., Ltd., is your comprehensive China-based manufacturer and factory partner for Ultra Precision CNC Turning Machining Service. Since 2007, we have built our reputation on delivering sub-micron precision at industrial scale, serving over 5,000 customers worldwide with a cumulative delivery of more than 1.3 million precision parts. Our integrated service model—spanning design consultation, process engineering, precision manufacturing, quality inspection, and logistics—ensures that every project, whether a single prototype or a million-piece production run, receives the same uncompromising attention to detail and quality.
Our ultra-precision turning service is designed for engineers and procurement professionals who demand more than just basic CNC turning. We specialize in the kind of high-tolerance, complex geometry work that ordinary machine shops cannot handle, providing a complete manufacturing solution that begins with your CAD file and ends with inspected, ready-to-assemble components delivered to your doorstep.
We offer more than just machining. Our end-to-end service includes:
1. Design for Manufacturability (DFM) review: our engineers analyze your designs for cost optimization and quality improvement
2. Material selection guidance: helping you choose the right material for your application requirements
3. Prototype development: rapid iteration with MOQ as low as 1 piece
4. Volume production: scalable from small batches to high-volume manufacturing
5. Surface treatment integration: vacuum heat treatment, anodizing, gold plating, ion polishing, and more
6. Assembly support: complete sub-assembly and final assembly services
Our precision turning service caters to a broad spectrum of high-tech industries where quality and reliability are non-negotiable:
● Medical devices: implantable components, surgical instruments, diagnostic equipment parts
● Semiconductor: wafer handling components, test fixtures, vacuum system parts
● Optical communication: fiber optic connectors, lens housings, precision alignment components
● Aerospace: turbine components, hydraulic system parts, sensor housings
● Automotive: fuel injection components, transmission parts, sensor elements
● Scientific research: laboratory instruments, experimental apparatus, custom precision parts
What sets our Ultra Precision CNC Turning Machining Service apart from the competition? It is the combination of extreme precision, process reliability, and comprehensive support that makes Sanluo the preferred partner for companies that refuse to compromise on quality.
With achievable accuracy grades from IT0 to IT5, we operate at the frontier of what is mechanically possible in turning. Our repeat positioning accuracy of ±0.0001mm and spindle rotation accuracy of 0.0001mm enable us to hold tolerances that most shops cannot even measure. This level of precision is not just a specification on a datasheet—it is verified on every critical dimension of every part we produce.
Our turning process incorporates several advanced technologies that deliver tangible benefits:
1. Ultra-low cutting force technology: minimizes workpiece deformation, critical for thin-walled and micro-scale components
2. High-speed precision turning: increases efficiency by 2-3x compared to conventional methods while maintaining superior surface quality
3. Dry cutting capability: environmentally friendly, eliminates coolant contamination concerns, and reduces post-processing requirements
4. Diamond tool management: tip radius control from 0.01-0.1mm with wear compensation of ±0.0001mm
Precision does not have to come at a prohibitive cost. Through continuous process improvement, optimized tool paths, and efficient production scheduling, we deliver premium quality at competitive prices. Our batch processing techniques reduce per-unit costs for volume production while maintaining the tight tolerances that define our service.
Our technical depth is what truly differentiates our service. From micro-scale components to large precision parts, from simple shafts to complex multi-feature geometries, we have the expertise and equipment to handle your most challenging turning requirements.
