CNC Turning & Swiss Lathe Turning Services

HKAA provides professional CNC turning services for custom precision metal and plastic parts. With 24 years of CNC machining experience, 400+ CNC machines, and advanced quality control systems, we support global B2B customers from prototype development to batch production. Our CNC turning capabilities are suitable for producing high-precision round parts, shaft parts, threaded parts, sleeves, bushings, pins, connectors, spacers, pulleys, rings, fittings, and other custom turned components. We serve customers in aerospace, medical equipment, automotive, robotics, semiconductor, industrial automation, clean energy, defense communication, testing equipment, industrial machinery, and sport hobby industries.

CNC turning is a precision machining process used to produce parts with cylindrical, round, threaded, or rotational features. During the process, the workpiece rotates while cutting tools remove material to create the required shape, size, and surface finish.

CNC turning is ideal for parts that require:

1. Tight dimensional tolerance
2. Smooth surface finish
3. Stable repeat production
4. High concentricity
5. Threaded or grooved structures
6. Cost-effective batch manufacturing

HKAA can manufacture custom CNC turned parts according to your 2D drawings, 3D files, samples, material requirements, surface treatment needs, and assembly requirements.

HKAA provides CNC lathe machining for precision round and cylindrical components. We can produce custom shafts, bushings, sleeves, pins, spacers, washers, pulleys, rings, adapters, connectors, threaded parts, and mechanical fittings.

This service is widely used for automotive parts, industrial equipment components, robot parts, machinery parts, and automation equipment parts.

Swiss turning is suitable for small, long, thin, and high-precision components. It is commonly used for precision pins, micro shafts, medical parts, connectors, fasteners, electronic components, and small mechanical parts.

HKAA is equipped with Tsugami Swiss-type machines, supporting stable production of small precision parts with excellent repeatability.

For parts that require both turning and milling features, HKAA provides turn-mill machining services. This process can complete turning, milling, drilling, tapping, slotting, and other machining operations in one setup.

Turn-mill machining is suitable for complex shafts, valve parts, connectors, transmission components, automation parts, and custom mechanical components. It helps improve machining accuracy, reduce secondary operations, and shorten production time.

HKAA also supports automatic lathe turning for high-volume small parts. This process is suitable for parts that require stable production efficiency, consistent quality, and competitive unit cost.

Typical products include pins, screws, nuts, sleeves, small shafts, spacers, inserts, and precision hardware components.

HKAA can process a wide range of materials for CNC turned parts, including:

Aluminum: 6061, 6063, 6082, 7075 etc
Stainless Steel: 304, 316, 316L, 17-4PH, 420 etc
Steel: carbon steel, alloy steel, tool steel etc 
Copper & Brass: copper, brass, bronze etc
Plastics: POM, PTFE, PEEK, nylon, ABS, PC etc 
Engineering Materials: customized materials according to customer drawings

We can also support material verification and inspection according to project requirements.

HKAA can manufacture many types of custom CNC turned parts, including:

1. Precision shafts
2. Bushings and sleeves
3. Pins and dowels
4. Spacers and standoffs
5. Threaded components
6. Rings and collars
7. Pulleys and rollers
8. Connectors and adapters
9. Valve components
10. Medical device components
11. Robot and automation parts
12. Automotive machined parts
13. Semiconductor equipment parts
14. Industrial machinery parts

Whether you need simple turned parts or complex turn-mill components, HKAA can provide reliable manufacturing support.

We can provide surface finishing according to customer requirements, including:

Anodizing, hard anodizing, black anodizing, plating, nickel plating, zinc plating, passivation, polishing, sandblasting, brushing, black oxide, powder coating, DLC, QPQ, and other surface treatments.

Surface treatment can improve corrosion resistance, wear resistance, appearance, hardness, and product performance.

Quality is one of HKAA’s key advantages. We are certified with AS9100, IATF 16949, ISO 13485, and ISO 9001, supporting customers in demanding industries such as aerospace, automotive, medical, and industrial equipment.

Our inspection equipment includes ZEISS CMM, HEXAGON CMM, 2D measuring machines, 2.5D measuring machines, height gauges, roughness testers, video microscopes, hardness testers, spectrometers, film thickness testers, gear testers, tensile testers, and concentricity measuring instruments.

We can provide quality documents such as:

1. FAI
2. PPAP
3. APQP
4. ISIR
5. Material certificates
6. Dimensional inspection reports
7. Surface treatment reports

This helps customers reduce sourcing risk and ensure parts meet project requirements before shipment.
