CNC Turing

A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. On the lathe, drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing. Lathes are mainly used for machining shafts, discs, sleeves and other workpieces with revolving surfaces, and are the most widely used type of machine tools in machinery manufacturing and repair factories. Machines for rotary machining such as milling machines and drilling machines are derived from lathes.

CNC Milling

A milling machine refers to a machine tool that mainly uses a milling cutter to machine various surfaces on a workpiece. Usually the rotary motion of the milling cutter is the main motion, and the movement of the workpiece (and) the milling cutter is the feed motion. It can process planes, grooves, and various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments. Milling machine is a kind of machine tool with a wide range of uses. It can process planes (horizontal, vertical), grooves (keyways, T-slots, dovetails, etc.), toothed parts (gears,spline shafts, sprockets, etc.) Helical surfaces (threads, helical grooves) and various curved surfaces.

In addition, it can also be used to process the surface of the revolving body, the inner hole and the cutting work. When the milling machine is working, the workpiece is mounted on the table or on the accessories such as the indexing head. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the table or the milling head, and the workpiece can obtain the required machining surface. The productivity of the milling machine is high due to the multi-tool interrupted cutting. A machine tool that mills a workpiece with a milling cutter. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

CNC turning can work with a variety of materials including metals such as steel, aluminum, brass, copper, and titanium, as well as plastics like nylon, PVC, and acrylic.

CNC turning services offer many benefits, such as high accuracy, repeatability, and the ability to produce complex parts with tight tolerances. It also allows for a faster and more efficient production process with fewer errors.

CNC turning involves rotating the material while a cutting tool shapes it, while CNC milling involves stationary material with a rotating cutting tool. CNC turning is typically used for cylindrical or round parts, while CNC milling is used for flat or irregularly shaped parts.

The duration of a CNC turning project can vary depending on the complexity of the part and the quantity required. However, it usually takes a few hours to a few days for a single part to be completed.

CNC turning services are utilized in various industries such as automotive, aerospace, medical, electronics, and manufacturing.

CNC turning part surface roughness

The surface finish of custom CNC turning parts is very important in order to ensure proper performance. Surface roughness can affect the durability and functionality of a part, as well as its aesthetic appearance. To achieve a smooth surface finish when CNC turning, the appropriate cutting tool must be selected and carefully sharpened. Additionally, given the speed of the machining process, coolant should be used to reduce heat generation and minimize wear on tools. Additionally, various other parameters such as feed rate, cutting speed and depth of cut should all be optimized for the material being machined in order to achieve desired surface finishes.

Surface roughness has a big impact on custom part usage. Generally speaking, a small surface roughness value will improve the fit quality, reduce wear and prolong the service life of the parts, but the processing cost of the parts will increase. Therefore, it is necessary to select the surface roughness value correctly and reasonably. When designing a part, the choice of surface roughness value is determined according to the function of the part in the machine.
