Lathing Services

Product Introduction

Lathing Services from Hehua Machinery Technology are designed for manufacturers requiring high-precision, custom-machined components with stable quality and reliable delivery. Our CNC machining capabilities cover turning, milling, boring, drilling, tapping, reaming, chamfering, rolling, and complex multi-axis processing.

We process a wide range of metal and engineering plastic materials, including ductile iron, gray cast iron, carbon steel, alloy steel, stainless steel, aluminum alloy, brass, copper, POM, nylon, acrylic, and other engineering plastics.

With complete CNC machining equipment, CMM inspection, independent process control, and supporting casting and forging capabilities, we provide an integrated solution from blank production to precision machining and finished assembly. Drawing customization, rapid sampling, small-batch production, trial production, and mass production are all supported.

Key Product & Service Features

High-Precision CNC Machining

Our precision machining service supports CNC turning tolerances from ±0.005 to ±0.02 mm and CNC milling tolerances from ±0.008 to ±0.03 mm. Boring tolerance can reach ±0.005 mm, while drilling and tapping tolerance can reach ±0.02 mm.

Surface roughness can be controlled from Ra0.8 to Ra3.2 according to component requirements, with flatness up to ≤0.02 mm/100 mm.

These capabilities are suitable for precision shaft and hole fitting, sealing grooves, pressure-resistant components, precision mounting surfaces, and threaded holes.

Full-Process CNC Machining

The production system includes vertical and horizontal CNC machining centers, turn-mill composite machining centers, CNC lathes, CNC boring machines, and drill-tap centers.

The machining process can integrate:

• CNC turning

• CNC milling

• Boring

• Drilling

• Reaming

• Tapping

• Chamfering

Drawing & Reverse Engineering Support

We accept mainstream 2D and 3D design formats, including CAD, STEP, IGS, SolidWorks, UG, and other commonly used engineering files.

For customers without complete production drawings, reverse engineering and sample-based development can also be supported. Physical samples can be used for dimensional mapping, drawing development, and manufacturing process optimization.

This service is suitable for:

• New product development

• Non-standard component customization

• Replacement component production

• Imported component localization

• Old equipment part reproduction

• Drawing standardization

• Mass production process optimization

Engineers review drawings before production to help identify tolerance conflicts, difficult machining areas, material risks, and potential cost-saving opportunities.

Quality Control & Inspection

Quality is controlled throughout the entire manufacturing process. The quality management system follows ISO 9001 requirements, with inspection covering incoming materials, first articles, in-process machining, finished products, and final shipment inspection.

For critical components, inspection can include:

• CMM dimensional inspection

• First article inspection

• In-process inspection

• Final inspection

• 100% inspection of key dimensions

• Material traceability

• Mechanical property testing

• Spectrum analysis

• UT non-destructive testing on demand

• MT non-destructive testing on demand

A complete dimensional inspection report and batch quality inspection certificate can be supplied with shipments when required.

Production & Delivery Capacity

With more than 10 CNC machining centers and a full range of CNC machining equipment, we support stable production from blanks to finished components. Supporting casting and forging workshops help reduce external processing links and improve production coordination.

Monthly production capacity can reach more than 50,000 pieces, making the service suitable for prototype development as well as continuous mass production.
