CNC custom machining can be said to be one of the fastest custom machining methods in the custom industry. From design optimization drawings, production to packaging and transportation, processing orders and delivery can be completed within a few days. Proofing simple machining parts can be completed in one day, and complex parts can be completed in 3 days.
What is CNC Custom Machining?
CNC custom machining usually refers to the production of small batches of CNC machined metal parts according to customers’ specific specifications and individual needs and uses. At the same time, it ensures the quality of parts production and processing, on-time delivery, cost-effectiveness and production and mahcining capabilities.
CNC Custom Machining Method
In short, CNC custom machining is the production of parts with a clear purpose in CNC turning, CNC milling, automatic lathes and 5-axis CNC machining centers, which is different from parts that do not exist elsewhere.
1. Turning
Lathe processing is a part of mechanical machining. Turning tools are mainly used for turning rotating workpieces. Lathes are mainly used for processing rotating or non-rotating workpieces with rotating surfaces such as shafts, discs, and bushings. It is the most widely used machine tool machining method in machine manufacturing and repair shops.
2. Milling machining
A common metal cold processing method, which is different from turning is that the tool rotates at a high speed under the drive of the spindle during the milling process, and the processed part does not move.
The difference between turning and milling:
Turning is used to machine rotating parts. The parts are clamped on the spindle of the machine tool by a three-head chuck and rotate at a high speed. Then use the turning tool to move the tool according to the generatrix of the revolving body to cut out the appearance of the product. The lathe can also process inner holes, threads, bites, etc. The latter two are low-speed processing.
3.3 Shaft machining
The three-axis machine tool contains three linear axes XYZ, and its structure is relatively simple. During the machining process of the three-axis machining center, the direction of the tool axis will not change, the movement mode is also limited, and the programming is relatively simple. The tool rotation axis can rotate, but it can only move intermittently, and the direction of the tool remains unchanged during the movement along the entire cutting path. The cutting state of the tool tip cannot be perfect in real time.
4.5-axis machining
The five-axis machining center has the characteristics of high efficiency and high precision, and complex machining can be completed in one clamping of the workpiece. It can be adapted to the processing of modern molds such as auto parts and aircraft structural parts. There is a big difference between a five-axis machining center and a five-sided machining center.
Many people do not know this and mistake the pentahedral machining center for a five-axis machining center. The 5-axis machining center has 5-axis x, y, z, a, and c. The xyz and ac axes form a five-axis simultaneous machining.
Good at space surface processing, special-shaped processing, hollow processing, punching, oblique hole, oblique cutting, etc. The “Pentahedron Machining Center” is similar to the three-axis machining center, except that it can do five faces at the same time, but it cannot perform special-shaped machining, beveled holes, cut bevels, etc.
On the surface, a five-axis machine tool has two more rotation axes than a three-axis machine tool. That is to say, in addition to the three linear axes of XYZ, a 5-axis machine tool also includes two AC rotation axes around the three linear axes of XYZ. In contrast, 5-axis and 3-axis are mainly reflected in processing capabilities. Five-axis machine tools can do the work of three-axis machine tools, but three-axis machine tools cannot do five-axis work. Due to the existence of two rotating axes, 5-axis machine tools have stronger processing capabilities. In addition, the 5-axis improves the intermittentness of 3-axis rotation.
In addition, there are other processing methods, and different processing methods are adopted for different processing requirements of customers.
For many reasons, many times engineers cannot obtain existing parts or cannot obtain reasonable prices. This is undoubtedly a hindrance to new projects for engineers. Under the influence of many reasons, there will always be parts that do not exist.
For example, non-standard parts need to be customized, special requirements for parts, and so on.
Completely ordinary parts may need to be processed and customized, such as custom logos or laser engraving, or they may be parts with missing additional functions.
Due to the cost consumption in the short-term production, there is usually a minimum order quantity. In emergency production, because the production time is short and there is very little minimum order quantity, it is necessary to quickly manufacture high-quality parts in the custom machining production, which can ensure fast and quality completion.
During processing, some customers want to change materials to customize processed parts, which will reduce production efficiency and time, but CNC processing can quickly replace materials for production. Some parts have different applications and special materials are needed, so they must be customized. Each new product part comes out and needs to go through a customized sample experiment and test before mass production, and the requirements are more stringent than other parts.
CNC machining customization is extremely sophisticated in the metal industry (stainless steel, titanium, aluminum, copper, iron, etc.), and can be more precise and tailored than plastic machining. Both metal and plastic materials have different advantages and functions, and they can produce beautiful and high-quality product parts in emergency or routine conditions.
Reasons for CNC Custom Machining
1. Not available from the supplier.
2. All parts are non-standard parts.
3. Need to quickly manufacture high-quality parts in an emergency
4. A machinery factory willing to produce small batches
5. Multiple elements can form a part
6. Need to change materials to make processed parts
Summarize
CNC custom machining is a kind of precision machining, which has advantages in the small batch custom machining industry. When choosing customization, you need to pay attention to the purpose and manufacturing purpose of the part processing, so that the design and production machining speed can be improved, and high-quality custom-made metal parts can be completed.
