China CNC Machining

We’ve built a reputation for producing almost all kinds of precision machined parts to our customers. At our own CNC machining shop in China,  We maintain an array of advanced machining equipment that allows us to provide a large number of CNC turning & milling services. And we have several long time cooperate CNC machining supplier, can provide swiss machining services, CNC Broaching and grinding services.

CNC Turning Services

Tianhui Machine company produce precision CNC turned parts. like other  China CNC Machining services we offer, We spare no effort to ensure the highest quality lathe and operators. As a result, our CNC turning services offer tremendous value to customers through precise CNC turning and timely turnaround.

Since our business formed in 2007, we have been committed to providing unparalleled service to a wide range of businesses. Contact us now and we are always ready to provide you with very competitive custom CNC turned parts

Broaching Services

Broaching is a machining process that uses a broach to remove material. There are two kinds of broaching: linear and rotary. linear broaching is the more common process in China, where the broach is run linearly against a surface of the workpiece to effect the cutting.

The shape of the broach is similar to the saw, a typical broach have 3 distinct sections, rough/semi-finish/finished teeth. Below picture shows a pull broach’s construction

Broaching is used to make odd shapes with precision dimension, like keyway, splines, and Hexagon.

The broaching process is usually used for mass production and can save a lot of cost compared to other machining processes.

Swiss Turning Services:

Swiss turning is suitable for producing large numbers of small, tight tolerance turning parts, Our swiss machining supplier has 60+ swiss turning lathe, they can produce swiss turned parts from diameter 0.5 mm to 32 mm.

Key Advantage of  China CNC Machining

Beside competitive price and on-time delivery, Customer chooses us because we can meet their various requirements for custom machined parts. Whether it’s a simply turned part or a complex machined part, we can provide it. Our main advantages are as follows:

We are good at machining of Castings or Forgings

Many western machining shops tend to use bar stock to produce machined parts. Bar stock, also called slug, blank or billet. Bar stock can be obtained in several extrusion shapes and lengths. The commonest shapes are round, rectangular, square and hexagonal or hex. bar stock may then be sawed, turned, milled, or ground to remove material and make to the final shape.

Machining of casting or forgings can reduce product cost

We not only use bar stocks to produce machined parts,  But We are also very good at producing machined parts from Castings or Forgings. It can significantly reduce the raw material use and machining cost, Especially for complex shape parts. Therefore, we are able to provide very competitive price products to the customer.

Although the use of castings or forgings to produce machined products can significantly reduce product prices, it also places high demands on machine shops. The machine shops need specialized skills to control the quality and delivery of castings or forgings and know how to machine them.

Our Purchasing staff has experience working in a foundry or forging factory and they know how to control the quality or delivery of the blank. We inspect the blank for incoming inspection to ensure that the qualified blank enters the next step. At the same time, we have several long-time cooperated casting and forging supplier. Our machining operations staff also know how to design and manufacture machining fixtures for casting or forging blanks.

Because we have over 10 years experience in machining of castings or forgings, now we can machining of:


High standard Heat treatment & Surface treatment services:

We work with one of the best heat treatment plants in the city, with advanced heat treatment equipment and testing tools. So they provide heat treatment services for some Fortune 500 companies. Their heat treatment services include whole heat treatment, surface heat treatment, and chemical heat treatment.

And we have several Surface treatment supplier, they can provide various surface treatment services for your machined parts.

Quality management

We understand that quality is always the most important for manufacturing. Our factory have ISO 9001 quality management system certification. and we are towards to TS 16949 and 5S management.


Quality Control Equipment

At our well-organized machining shop, We have equipped advanced inspection tools, such as:

  • CMM
  • Image measuring
  • MPI
  • Hardness tester
  • Roughness tester
  • various caliper and thread gauge
