Types of Precision Machining That We Offer

Precision CNC Milling Machining 56 1
Utilizing advanced multi-axis milling machines imported from the United States, Japan, and China’s leading brand, we ensure CNC-milled parts meet tolerances of +/-0.05mm, with critical dimensions maintained within +/-0.005mm.
 
Our experienced team specializes in crafting high-precision components for demanding sectors, such as aerospace and medical industries.
 
Our 5-axis CNC milling machines feature an integrated inspection system that monitors part dimensions in real-time during machining. The system automatically adjusts programs and parameters to guarantee accurate part production.
 
Material Compatibility: Stainless Steel, Aluminum, Tool Steel, Copper,  Brass, Titanium, Plastics
Precision CNC Turning Machining 56 2
In contrast to CNC milling, CNC turning employs a single-point cutting tool to make precise cylindrical cuts in a rotating workpiece. This automated process delivers exceptional accuracy and repeatability, making it ideal for crafting circular or tubular components. The CNC turning lathe holds and spins the material while machining it at high speeds.
Our skilled technicians achieve remarkable precision in component production, thanks to our professional-grade CNC turning machines.
 
While CNC milling excels for short-run prototypes and parts under 2.5” OD, CNC turning is better suited for larger parts exceeding this size in short-run volumes.
 
Typical CNC turning applications include functional prototypes, spacers, manifolds, fittings, shafts, and bushings.
Precision EDM Machining 56 3
In addition to our CNC services, Kesu offers industrial-grade wire electrical discharge machining (EDM) to clients worldwide, enabling precise cutting of various electrically conductive materials.
 
The wire EDM process uses an electrically charged wire, positioned between two guides, to act as one electrode, while the workpiece forms the second. This setup generates electrical discharges that erode material, effectively shaping it without direct contact.
 
As the wire never touches the material, EDM is ideal for crafting extremely small and delicate parts or prototypes. It excels at cutting challenging metals like steel, bronze, copper, and titanium, which are difficult to machine with other methods.
 
Wire EDM is frequently utilized to manufacture circuit boards and critical components for the automotive, aerospace, and consumer electronics sectors.
Precision CNC Grinding Machining 56 4
Kesu’s prototyping facility features high-precision grinding machines, perfect for producing metal parts and prototypes with extremely tight tolerances. The grinding process employs a rotating wheel made of bonded abrasive particles to remove material from a workpiece, shaping it to precise specifications.
 
Similar to wire EDM, precision grinding is ideal for creating small metal components and larger parts requiring stringent tolerances, such as those used in medical devices, aerospace components, scientific instruments, and beyond.
 
Kesu’s skilled team will guide you in selecting the best grinding method and tool for your part, ensuring all specifications and requirements are met.

Precision Machining FAQ

When to choose precision machining?

Some engineers set excessively tight tolerances during part design, which is inefficient. For example, selecting a +/-0.01mm tolerance when +/-0.05mm is adequate can drastically raise production costs. Yet, when extremely tight tolerances like 0.01mm are essential, precision machining provides unparalleled accuracy and reliability.

What materials can be used with precision machining?

Precision machining supports a diverse array of materials, including aluminum, brass, copper, steel, titanium, and robust plastics like PPS and PEEK. Contact us to explore the full range of materials available for precision machining.

How can Kesu guarantee tight tolerances?

We employ top-tier machines for precision CNC milling, turning, EDM, and grinding, along with various in-house tools, while maintaining a stable workshop temperature with AC. Coupled with our engineers’ expertise and qualifications, plus thorough inspections of machines and processes, we guarantee consistent quality, even for the most challenging projects.
