Product Introduction

We specialize in CNC turning of complex, high-precision, and uniquely shaped parts. Leveraging multi-axis turning-milling machining centers imported from Germany and Japan, our team of experienced engineers, and a rigorous quality control system, we provide clients with a one-stop service from design optimization and prototyping to mass production. Whether meeting the demanding requirements of aerospace, medical devices, or optical instruments, we deliver precision machining solutions that exceed expectations.

Product Description:

Complex part turning exceeds the processing limits of traditional lathes, encompassing special-shaped structures, thin walls, deep holes, fine threads, non-standard threads, and the formation of difficult-to-machine materials. Our multi-axis CNC turning centers and turning-milling technology enable turning, milling, drilling, tapping, and boring operations in a single setup, significantly improving machining efficiency and achieving precise geometric and positional tolerances. We are your ideal partner for developing high-end products and solving complex manufacturing challenges.

Product Features and Applications

Our Technological Advantages and Process Features

Our cutting-edge equipment cluster: We boast 4-axis and 5-axis simultaneous turning-milling machining centers (such as the DMG MORI NTX series and MAZAK INTEGREX series). Equipped with Swiss-type lathes, we specialize in efficient and precise machining of slender shaft parts.

The full range of equipment supports C-axis and Y-axis machining, enabling the realization of extremely complex geometric features.

Excellent material application capabilities: We process a wide range of stainless steels (303, 304, 316, 17-4PH), aluminum alloys (6061, 7075), titanium alloys (Ti6Al4V), nickel-based alloys (Inconel 718), and engineering plastics such as PEEK.

We offer specialized solutions for difficult-to-machine materials, effectively controlling machining stress and deformation to extend tool life.

We address extremely complex geometric challenges:

Machining eccentric parts, multi-curved parts, cams, and parts with non-circular cross-sections.

Machining thin-walled parts (capable of wall thicknesses <0.5mm) effectively controls deformation and ensures dimensional stability.

We also offer micro-hole machining, deep hole drilling (aspect ratio >10:1), and precision internal and external thread machining. Comprehensive Quality Assurance and Secondary Services:

Our laboratory-grade testing room is equipped with a coordinate measuring machine (CMM), an optical image measuring instrument, a roundness tester, and a roughness tester.

We offer a full range of surface treatment services, including anodizing, electroplating, passivation, sandblasting, and laser engraving, providing a truly one-stop service.

FAQ

Q1: What is mill-turning? What are its advantages over traditional CNC turning?

A: Mill-turning is an advanced manufacturing technology that integrates multiple turning and milling functions on a single machine tool. Its core advantage lies in completing all or most machining steps in a single setup, eliminating the cumulative errors associated with multiple setups. This significantly improves the accuracy of geometric tolerances, such as position and concentricity, and shortens overall production cycle time.

Q2: What are some examples of the most complex parts you can handle?

A: We specialize in machining flanges with off-axis holes, shafts with milled features, special-shaped nozzles, and housings with circumferentially distributed oblique holes. If your part requires both external turning and milling of flat surfaces or slots, this is typically a typical application for our mill-turn combination machining.

Q4: How do your production capacities and strategies differ between low-volume prototypes and large-scale production?

A: We flexibly address different order requirements:

Prototype: We prioritize the use of more flexible equipment, focusing on rapid iteration and precision verification.

Mass Production: We strive for ultimate efficiency and cost control through optimized machining parameters, specialized tooling and fixture design, and dedicated production lines. We also utilize SPC process control to ensure long-term quality consistency.

Q5: How do I get a quote? What information do I need?

A: To provide the most accurate and prompt quote, please provide the following information: Detailed technical drawings (PDF/DWG/STEP/IGS format) showing all dimensions, tolerances, geometric tolerances, and technical specifications. Material specifications (e.g., Aluminum 6061-T6). Surface finish requirements (e.g., anodized, black, 25μm thickness). Required quantity (prototype quantity or annual production quantity).
