Product Introduction

External turning is a precision machining technology that uses CNC lathes to perform rotary cutting on materials such as metals and plastics. It is widely used in the manufacture of rotating parts such as shafts, threads, and sleeves. Its high precision, high efficiency, and strong adaptability have made it an indispensable process in modern manufacturing, particularly for the production of key components in the automotive, aerospace, and medical device industries.

External Turning Product Description:

Processing Principle

The workpiece rotates under the spindle's drive, while the turning tool feeds axially or radially, removing excess material to create precise external cylindrical, stepped, and tapered surfaces. It supports a variety of operations, including turning, boring, grooving, and threading.

Technical Parameters

Precision Grade: Dimensional tolerances up to ±0.01mm, surface roughness Ra ≤0.8μm.

Applicable Materials: Carbon steel, stainless steel, aluminum alloy, titanium alloy, and engineering plastics.

Maximum Processing Diameter: φ10mm to φ500mm, depending on machine specifications. Equipment Types: Economical general lathes, high-precision CNC lathes, and multi-axis turning-milling centers.

Product Features and Applications

Ultra-high-precision CNC system closed-loop control compensates for tool wear, ensures batch-to-batch consistency, and meets the demands of precision part machining.

Efficient Production: Synchronous operation of multiple turrets shortens cycle times, making it suitable for high-volume turning orders.

Flexible Adaptability: The rapid tool change system supports machining complex structures such as thread turning and curved contours.

Cost Optimization: Reduces manual intervention, lowers scrap rates, and helps companies control component manufacturing costs.

Wide Material Compatibility: From aluminum alloys to high-temperature alloys, high-quality machining can be achieved through optimized cutting parameters.

FAQ

Q1: Can we process difficult-to-cut materials such as stainless steel?

Yes. Specialized tooling and cooling technology address the issues of hardening and tool sticking during stainless steel turning.

Q2: What is the minimum order quantity and lead time?

We support small-batch trial runs (minimum 50 pieces). Large-volume orders have a lead time of 7-15 days, depending on the complexity of the drawing.

Q3: How do you ensure the rust resistance of parts?

We offer metal surface treatment services such as oxidation, electroplating, and passivation to extend the life of parts.
