What kind of CNC machining processes available?

CNC Machining Process for a mold

CNC Machining is a comprehensive process usually used as the final step to get the precise dimensions during the whole manufacturing procedure of a metal part.

In Sinoway, we can supply almost all kinds of CNC machining processes, turning, milling, boring, reaming, planing, etc. And with the CNC machining center, we can make the molds for our own casting and forging factories.

The diverse processes enable us to choose the most optimum solution for the clients’ projects, manufacturing out the right metal products at the lowest cost. And this will always be one of our most competitive advantages.

Turning

Lathe turning is a part of the mechanical machining procedure, and there are two main types of processing.

1. Fix the cutting tool and turn the unshaped workpiece in rotation.
2. Fix the workpiece and rotate it at high speed, but move the turning tool (tool holder) laterally and longitudinally.

Lathe machining is mainly workable for turning shafts, discs, sleeves and other workpieces with rotary surfaces, such as internal and external cylindrical surfaces, conical surfaces, formed rotary surfaces and end faces. And the lathe turning can also process threaded bodies.

And drill bits, reamers, taps, and knurling tools are also available on the lathe for a corresponding machining process. The lathe turning techniques are the most widely used in machinery manufacturing and repairing factories among the various machining procedures.

Milling

CNC machines can perform machining of complex rotary shapes. We need to fix the workpiece during the milling process, using a high-speed rotating milling cutter to go over the blank and cut out the desired shape and features.

Conventional milling more often worked on workpieces with simple profile features such as contours and slots. And CNC milling machines can perform machining of complex shapes. For example, a Milling and Reaming center can perform 3-axis or multi-axis machining on molds, inspection tools, fixtures, thin-walled complex surfaces, prostheses, blades, etc.

While choosing CNC milling, we should consider the advantages and critical role of the CNC milling machine.

Boring & Reaming

Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve the accuracy, reduce the surface roughness, and better correct the original hole axis skew. The boring process on the CNC machining center is to carry out the expansion or refinement of the original hole on the steel parts. And with this process, we can improve the holes’ co-axiality, cylindricity, and surface smoothness. Therefore, boring is commonly used as a high precision machining method in the final process.

Reaming is a method of removing a thin metallic layer from the inner wall of a hole with a reamer. It can improve the hole’s dimensional accuracy and surface quality. And reaming is one of the finishing methods for holes and is widely used in mass production. As a matter of fact, for smaller holes, reaming is a more economical and practical machining method compared to internal grinding and precise boring.

Benefits of a CNC custom machining process

Compared with the traditional machining process, the CNC custom machining process has the following main benefits.

1. More flexibility – CNC machining depends mainly on the CNC program, which is different from ordinary machining and does not require frequent replacement of tools and fixtures and periodic adjustment of machine tools. Therefore, CNC machining is more suitable for regular replacement of parts, more ideal for single-piece, small batch production, and new products development. It will shorten the production preparation cycle and save many process equipment costs.
2. Higher accuracy – Because there is no manual operation, CNC custom machining processes can avoid operator-related errors. And the CNC device can compensate for system errors. And the machine takes a backlash-free transmission system, which leads to an almost zero-deviation on the mechanical transmission. Due to those factors, the accuracy can reach 0.005 ~ 0.1mm with the CNC processing machines.
3. Stable and reliable quality – Under the same processing condition and procedures, while processing a batch of parts using the same tools, we can get the workpieces with consistently stable quality.
4. Higher productivity – CNC machines can reduce machining and additional time effectively. Due to the rapid movement and positioning of the devices and the high-speed cutting process, CNC machining can reduce the semi-finished products’ turnaround time and improve productivity.
5. Better production condition – Input and edit the program, load & unload the workpieces and tools, monitor the machining status and inspect the workpieces. These are CNC machine operators’ main jobs, and the labor intensity is relatively lower than traditional machining. And the production environment of CNC machining is also cleaner and safer.
6. Easier for modern production management – With CNC machining stations, we can predict the machining time more accurately. Meantime, the tools and fixtures are much easier to be managed for standardized and modernized production. So the standardization of comprehensive machining information can be achieved.
