Shenzhen Ruiyihang Technology's Custom CNC Turned Parts are reliable when your project needs parts that are very precise and fit together tightly. We've been specialising in engineering-driven CNC turning solutions since 2008, and we can offer tolerances as close as ±0.02 mm and surface roughness as low as Ra 1.6. Our average team member has been machining for more than 15 years, which lets us handle everything from complicated shapes to fast development. With 15 CNC turning tools, including multi-axis turning-milling centers, we can help you with your projects from the prototype stage to mass production. For simple designs, we can get sample parts to you in as little as three days.

Precision parts called CNC turned parts are made on computer-controlled lathes. During the process, the material is rotated while cutting tools make it into cylinders or rounds.
You always get correct results that you can repeat. Because of this, turning is the best way to make shafts, bushings, pins, fits, and other parts that rotate.
Among our skills are:
Not all of our parts are stock. Each and every part is made exactly the way you want it.

There are no agents; you work directly with our experts. They look over your plans, give you advice on which materials to use, how to get the best measurement tolerances, and ways to make the design better in real life. Working together cuts down on mistakes and shortens lead times by a lot.
In industry, speed is important. After reviewing the picture, we give you a quote right away. It takes about 7 days to make a sample, and as little as 3 days to make a small part. Things are going well with your project.
OEM and ODM projects are what we do best. We can meet your needs whether they are for complicated geometries, special machining methods, or small runs. There is no job that is too hard.
Quality starts with the things that come in. We check the makeup of materials with spectrometer inspection. Our team uses accurate tools and callipers to take measurements while the product is being made. The final CMM check makes sure that all the measurements are exactly what you want them to be.
ISO 9001 rules guide our quality management. For uses that come into touch with food, we offer materials and certificates that are FDA-compliant.
Our 15 CNC turning tools and turning-milling centers can handle a wide range of tasks. We can help you with everything from simple bearings to complex parts with many functions. We're always willing to come up with new ways to do things and find answers to tough machining problems.
There are no shipping costs if there are quality problems within the first month of delivery. We will plan for remanufacturing within one week. Your happiness is our top concern.

Step 1: Material Verification
Every batch is tested with a spectrometer to make sure the license and material makeup.
Step 2: CNC Turning
Precision lathes with tungsten tools are used to make your parts with smooth surfaces and correct sizes.
Step 3: Secondary Operations
No matter what your plan calls for, we can thread, knurl, cut, mill, or polish.
Step 4: Surface Treatment
You can choose from passivation for stainless steel, anodising for aluminium, or finishes that are made just the way you want them.
Step 5: Final Inspection
Before packing, full checks of dimensions and surface quality are made.
Step 6: Fast Delivery
We offer global door-to-door shipping that is best for small sales, and we handle both taxes and shipping at the same time to make things easier for you.

Our Custom CNC Turned Parts are used in a wide range of situations in many industries, including:
Q: Can you make custom turned parts?
We CNC turn parts to your 2D or 3D CAD files with complete customisation.
Q: Do you support secondary operations on turned parts?
We offer drilling, milling, threading, and other secondary procedures for complicated designs.
Q: Can you assist with design optimization for turning?
We recommend DFM (Design for Manufacturability) to increase machinability, save costs, and boost productivity.
Q: How much tolerance is possible?
We typically maintain standards of ±0.02 mm and may explore tighter specs for your application.
Q: How is material quality assured?
Certified raw materials are spectrometer-inspected upon delivery to verify composition.
Q: What's your typical lead time?
Samples and basic components ship in 7 and 3 days, respectively. Production depends on volume and complexity.
