Online Customized Precision CNC Machining Service

Ruitai is a CNC machining company that provides CNC machining services. With multiple CNC machining shops, precise CNC machining solutions, and multiple sets of CNC machining tools, it can meet the needs of different CNC machining projects at the same time.

Ruitai CNC machining center provides you with various high-quality injection molding manufacturing, rapid prototyping, and mass precision parts manufacturing services.

Our wide range of CNC machining services covers CNC Milling, CNC Turning, Swiss CNC Machining, EDM CNC Machining, Plastic CNC Machining, and many more.

CNC Turning-1

CNC turning is ideal for machining deep holes, machined threads, and all types of cylindrical shapes with excellent surface finish, producing high-precision cylindrical parts, usually cones, disks, or combinations of shapes. It has the characteristics of high precision of processed parts, a short production cycle, and high similarity.

CNC-Milling picture

CNC milling is an excellent solution for rapid prototyping and end-use components, allowing your design team to realistically simulate the form, performance, and material properties of the final product and test components for suitability and manufacturability to prove and refine their designs. CNC milling can create complex prismatic shapes and flat surfaces for a variety of commercial and industrial products.


Rapid prototyping is the best solution when you need to quickly manufacture high-quality plastic injection molds or die-casting tools. It is a “fast food” part machining service for small batch production or rapid prototyping.


CNC surface grinding is a common machining method in precision CNC machining services, and surface grinding is the best CNC machining method if your part requires a very flat surface. Special grinding wheels pass over the surface of the workpiece under the CNC program of the digital motor to provide the final surface evenness.

CNC-plastic image

Alternative processing solutions for 3D printing materials. CNC prototyping plastic processing technology is generally used to make conceptual models of accurate functions, or plastic parts, which will come in handy before product development. Compared with other material processing, the price of plastic processing will be relatively affordable, and it can also meet the needs of small batch CNC processing and manufacturing.


Swiss CNC machining is currently the most suitable process for small precision parts in CNC lathes, capable of producing parts with tight tolerances. In this machining, oil is used as a coolant, originally developed for machining machines in the Swiss watchmaking industry. If you need to do precision small parts machining, then Swiss CNC machining is the best choice for you.

Online CNC Machining Services

CNC machining, also known as numerical control machining, refers to the computer numerical control system issuing instructions to make tools (such as drills, lathes, milling machines, grinding machines, milling machines, 3D printers, etc.) perform various movements that meet the processing requirements.

This is a subtractive manufacturing process. Its working principle is to use a computer-controlled machine tool to remove the material layer on the raw material (alias: blank) to form a specially designed part handicraft. Generally refers to the process of forming parts from prototype materials on CNC machine tools.

Unlike additive manufacturing processes such as 3D printing and formable manufacturing processes such as liquid injection molding. The process is suitable for a wide variety of materials such as common metals, glass, plastics, wood, composites, and foams.

CNC machine tools are machine tools controlled by computers, and the computers used to control machine tools are collectively referred to as CNC systems. The movement and auxiliary actions of CNC machine tools are controlled by commands issued by the CNC system. Our commonly used CNC lathes, such as CNC grinding machines, lathes, milling machines, etc., all belong to CNC machine tools…

Features of CNC machining

The biggest feature of online machining is the use of perforated belts (or magnetic tapes) to control machine tools for automatic machining. It is the key way to solve the difficulties of ordinary machining methods. The ability to perform high-precision machining of a wide variety of metal parts with complex contours makes it a popular choice for applications in many industries, including aerospace, automotive, medical devices, and more. Common such as aircraft parts, automobile engine parts, bicycle parts, and so on.

CNC Machining Application Scenes

Aerospace and Defense: CNC machining is common in aircraft component manufacturing. In addition, it is used in defense production. For example; weapons, turbines, wing assemblies, engine parts, cabin parts, ammunition, and other similar items.

Automotive industry: CNC machine tools produce various car and truck parts. Some examples include engine components, transmission components, suspension components,connecting rods, crankshafts, bushings, valve cores, valve guide rods, transmission shafts, brake discs, cylinder heads, hubs, engine internal parts, etc..

Medical equipment: CNC machining is also important for the manufacture of parts and equipment in the medical field, such as surgical equipment, orthopedics, dental equipment, surgical instruments, and other precision components.

Consumer goods: CNC machines can produce a wide variety of consumer goods. Such as circuit boards, computer casings, chassis, and other common household items.

Machinery and tooling: CNC machining is commonly used to produce components for a variety of machinery and equipment. Some examples include pumps, valves, and gears.

Prototyping and R&D: CNC machining is mostly used to produce prototypes and test parts for R&D purposes. Compared with traditional production methods, the production speed is at least 15 times that of traditional processing methods. It can reduce the cost of product development to a certain extent, shorten the time to market, and occupy the market earlier than competitors.

Jewelry Making:  Intricate jewelry requires the precision and repeatability that only CNC machining can ensure. The Swiss CNC machining services mentioned above are dedicated to high-precision, complex-shaped, multi-variety, and small-batch production. It can meet the growing demand of the market, and the production speed is fast, not as slow as handmade. That’s why it’s so popular in this field.

Molds: CNC machining of molds for the production of plastic and metal products. Compared with ordinary mechanical processing technology, the precision of molds produced by CNC processing technology is higher, because CNC processing has diversified characteristics, and a variety of different processing schemes can be formulated for the same processing task.

Metal machining: CNC machining is common in the production of metal components in a variety of industries including construction, agriculture, and mining.

In addition, CNC machining also uses multi-axis machining machines. Under the operation of standard NC programs, high-speed rotating tools and processing technology will greatly improve the efficiency and quality of parts processing. At the same time, the produced machined parts have higher consistency, accurate precision, and shorter cycle time.
