CNC Turning

What is CNC Turning

CNC (computer numerical controlled) Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. It refers to the automated machining process of shaping material, such as metal or plastic, using a CNC machine. It is an intricate and detailed method of creating custom parts and components using a lathe. CNC turning is a highly-skilled, Precision Engineering process.

About Xielifeng Tech

Our CNC turning machine

We have 40 SYMG HTC2050&HTC3250 cnc turning machines, can make part max size diameter 200mm, length 500mm, tolerance 0.005mm, roughness Ra0.2.
Why choose CNC Turning

  1. A series of set up reductions, machining complex-shaped parts needn’t complicated fixture loading. If you want to change the shape and size of parts, you only need to modify the parts processing program.
  2. The processing quality is stable, precision is high and the repeat accuracy is high.
  3. High production efficiency with multiple varieties and small batch production, which can reduce the time for production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
  4. Can process complex surfaces that are difficult to process with conventional methods, can even process an unmeasurable position.

CNC Milling

CNC milling is the machining process of using rotary cutters to remove material from a workpiece by feeding the cutter into the workpiece at a certain direction. The cutter may also be held at an angle relative to the axis of the tool. CNC mill covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

Our CNC milling machine

We have 3axis cnc milling machine Q’ty 16 and 4axis cnc milling machine Q’ty 4, machine included MAKINO V22, TAIKAN T-V850, JIRFINE V6&V8, JOINT VMC650, can make the part max size length 1000mm*width 600mm*height 500mm, tolerance +/-0.01mm, roughness Ra0.2.

Features of CNC milling

  1. High degree of automation with high production efficiency. Besides manual fixed the blanks, all the rest of the machining process can be fulfilled by CNC machine automated.
  2. The adaptability to the processing object is strong. When changing the machining object, besides replacing the tools and resolving the method of setting up the blanks, only reprogramming is required, needn’t any other complicated adjustments, thereby shortening the production preparation cycle.
  3. High precision machining and stable quality. The dimensional accuracy of machining is between 0.005mm to 0. 01mm, and not affected by the complexity of the parts.

Advantage of CNC milling

  • high production efficiency.
  • easy to operate, even no skilled workers.
  • high precision and high quality.
  • reduce tooling and fixture.
  • easy to manage the process.
  • reduce the inspection time.
  • reduce reject ratio.
  • easy to design and process changes, the processing setting is flexible.
  • easy to automate the operation process, one person can operate more than one machine.

Applications of CNC Machining

Design & Rapid PrototypingCar&Motocycle&BikeAircraftMedical3C Digital Products

Regardless of the manufacturing process used to create the end-use part, CNC machining is widely used by designers as a means of creating early and late-stage prototypes with short turnarounds times. CNC prototyping allow designers to rapidly iterate ideas without tooling costs or waiting times. It is one of the best ways to create concept model and function prototype to verify the design. Compared with other rapid prototyping methods, rapid CNC machining allows us to get tight tolerance prototypes in real materials fast.

CNC Prototyping is the preferred option to bring new design life among the other rapid prototyping methods, unless the products are designed for 3D printing or other methods only.

Aside CNC machining aluminum bike parts, CNC machining can also be applied to brass parts, stainless steel parts, plastic parts for car, motorcycle, truck, train, etc.

The left image is a part for drone.

Thanks to the extremely high precision of CNC machines, making the process suitable for safety-critical parts that will be used on aircraft.

Machinable aerospace parts include prototype engine components, fuel panels, landing gear components and engine mounts.

The machinability of different grades of titanium and stainless steel has made CNC machining a widely used process in healthcare, where it is frequently used to make implants, medical devices and surgical tools such as scalpels.

Tight tolerances and fast turnaround are especially important for projects such as titanium hip implants, which should be tailored to the patient’s anatomy.
