FAQ

Q What is the definition of CNC precision machining?

A CNC Precision Machining is a process that utilizes Computer Numerical Control (CNC) technology to machine precision parts. Through pre-programmed instructions, CNC machines are able to automatically perform complex machining operations to achieve precise control of part size, shape and surface quality.
Q What are the advantages of CNC precision machining?

A CNC precision machining offers several advantages, including high accuracy, efficiency and flexibility. The use of CNC technology enables precision machining of a wide range of parts with complex shapes, thereby improving productivity and quality.
Q Which industries are suitable for CNC precision machining?

A CNC precision machining is used in a wide range of industries, such as aerospace, automotive manufacturing, medical devices and electronics. Whether the material is metal, plastic or ceramic, it can be processed by CNC Precision Machining.
Q What is the machining capability of CNC Precision Machining?

A CNC Precision Machining has the ability to machine parts of various shapes and sizes, often with machining accuracies of ±0.01 millimeters or higher. The machining capability is mainly affected by the type and specification of CNC machine tools and the design of the machining process.
Q What is the cost of CNC precision machining?

A The cost of CNC precision machining is affected by a variety of factors, including part complexity, material selection, and machining process. Overall, CNC Precision Machining can be slightly more expensive than traditional machining methods, but can result in higher machining accuracy and quality.
Q How to choose the right CNC precision machining service provider?

A Selecting a suitable CNC precision machining service provider requires consideration of a number of factors, including technical strength, equipment capability, quality control system, lead time and service responsiveness. It is recommended to conduct sufficient market research and supplier evaluation, and select vendors with good reputation and professional services for cooperation.

Q What are the machining techniques/processes of CNC Turning Service?

A
Turning : This is one of the most basic machining techniques of CNC Turning Services. The workpiece is turned and cut with a cutting tool to give it symmetry in the axial direction. Turning can be used to make a variety of shapes including shafts, tubes and face parts.

Drilling : CNC lathes can be used to create holes in workpieces, from simple piercing to deep hole drilling for different parts.

Boring : Boring is a method used to machine internal diameters for the precise machining of large diameter holes and cylindrical holes.

Threading: The use of a threading tool to cut threads in a workpiece for use with bolts and nuts.

Facing : The cutting of the end face of a workpiece to make it flat and ensure the accuracy and parallelism of the end face.

Gear Cutting: CNC lathes can also be used to manufacture rotating parts such as gears to meet the needs of various transmission systems.
Q What types of parts are suitable for CNC Turning services?

A
Shaft Parts: Such as mechanical shafts, bushings, bearing housings, and other rotating parts that often need to be machined on a center axis.

Pipe fittings: These include pipe fittings, pipe connections, etc. These parts are usually machined on both the outside and inside diameters.

Threaded parts: such as nuts, bolts, screws, etc. These parts usually require machining on the outer diameter and threads.

End face parts: such as cover plates, gaskets and other parts that require a flat surface, these parts usually require end face machining to ensure their accuracy and surface quality.

Gear parts: These include various types of gears, which often require gear machining to ensure the accuracy and efficiency of their gear train.
Q What equipment is required for CNC Turning services?

A
CNC Lathe: As the core equipment of the CNC Turning service, CNC lathes are capable of rotating workpieces and machining them with cutting tools, featuring high precision and efficiency.

Automatic feed mechanism: The automatic feed mechanism is used to control the relative motion of the workpiece and cutting tool to automate and precisely control the machining process.

Cutting tools: CNC Turning service requires the use of various cutting tools, such as turning tools, drills, boring tools, etc., to meet the needs of different parts processing.

Clamps and fixtures: These are used to clamp and hold workpieces to ensure stability and precision in the machining process, while minimizing workpiece deformation and vibration.

CNC control system: CNC control system is used to control the movement and machining parameters of the CNC lathe, including speed, feed, tool path, etc. to ensure the accuracy and efficiency of the machining process.
