Our Core Machining Operations

We leverage cutting-edge equipment to support diverse shapes, geometries, and engineering requirements.

CNC Milling Services

Our CNC milling capabilities include 3, 4, and 5-axis machining. We use high-speed spindles and advanced tool paths to mill complex parts from bars, blocks, or castings. This process is suitable for high-precision geometries, deep cavities, pockets, and flat faces in both prototype and production volumes.

CNC Turning & Lathe Services

For cylindrical and round parts, our CNC turning and Swiss lathe centers provide ultra-precise machining. Live tooling allows us to mill slots, cross-holes, and flats during the turning process, reducing cycle times and setup costs. Ideal for shafts, screws, valves, rings, and fittings.

5-Axis CNC Machining

For parts with highly complex features requiring multiple setups, our 5-axis CNC machines provide a significant advantage. By rotating the part or spindle along five axes, we can machine undercuts, deep drafts, and angled holes in a single setup, improving dimensional accuracy and surface finishes.

Frequently Asked Questions

Answers to common questions regarding our CNC services, options, and quotation process.

How can I reduce the cost of my CNC machined parts?

You can reduce the cost of CNC parts by:

Avoiding deep pockets and internal sharp corners (radius them instead).
Using standard materials like Aluminum 6061 or POM instead of exotic alloys.
Minimizing the number of setups/orientations required to machine the part.
Relaxing tolerance requirements where high-precision is not critical.

What tolerances can Yistar achieve?

Our standard tolerance for machined metals is ISO 2768-m (fine), which translates to ±0.1mm. For critical mating surfaces, we can achieve tolerances down to ±0.01mm, and with precision ID/OD cylindrical grinding, we can target ±0.005mm.

Which files do you accept for custom manufacturing?

We prefer 3D CAD models in **STEP (.step, .stp)** or **IGES (.igs)** formats for pricing and programming. We also accept solidworks (.sldprt) or fusion 360 files. For critical dimensions, threads, or finishing requests, please also supply a matching 2D drawing in PDF format.

How do you guarantee the quality of parts?

We are ISO 9001:2015 certified. Every project undergoes a strict inspection protocol: first-article inspection, in-process checking, and final inspection using CMM (Coordinate Measuring Machines), optical projectors, and digital calipers. Inspection reports and material certificates (MTR) can be provided upon request.
