What is CNC machining?

Traditional machining is done by hand with ordinary machine tool operations, processing by hand shaking mechanical tools cutting metal, by eye with calipers and other tools to measure the accuracy of the product. Modern industry has long used computerized intelligent control of machine tools to carry out operations, CNC lathesaluminum cnc machining can automatically process any products and parts directly in accordance with the program programmed in advance by technicians. This is what we call "CNC machining". CNC machining is widely used in all mechanical processing of any industry, but also the development trend of mold manufacturing and important and necessary ways and means. "CNC" is the English ComputerizedNumericalControl (Computer Intelligent Control) for short.

What is CNC CNC machining?

Computerized intelligent control, referred to as CNC (NumericalControl). It is the use of digital information on the machine tool movement and production process control of a method. The use of CNC technology to implement processing control of the machine tool, or equipped with a CNC system called CNC (NC) machine tools. CNC control system contains: CNC device, program controller, spindle controller and tool walking device and other parts. CNC lathe is a machine, electricity, liquid, gas, light highly integrated goods. To realize the control of the machine tool, the geometric information is used to describe the relative speed between the tool and the workpiece and its process information to describe the machine tool processing must have some process parameters. For example: feed rate, spindle speed, spindle forward and reverse, tool change, freezing fluid switch, etc.. These information according to a certain format to produce processing documents (that is, the normal speaking of the CNC processing program) stored in the information carrier (such as hard disk, perforated paper tape, tape, etc.), and then read by the CNC system in the machine tool (or directly through the numerical keypad of the CNC system, or by means of communication input), according to and on the decoding, so that the machine action and processing parts. Contemporary CNC lathe is a typical commodity of mechatronics, is a new generation of production process, computer integrated manufacturing system and other technical basis.

The development trend of contemporary CNC lathe is high-speed, high precision, high reliability, multi-purpose, composite, intelligent and open structure. The key development trend is the development of software and hardware with open structure of intelligent multi-functional general-purpose CNC device. CNC technology is the basic of machining automation, is the key technology of CNC lathe, its level is related to the strategic significance of our country and reflect the level of national comprehensive strength. It develops with the development of information technology, microelectronics, automation control and detection technology. CNC machining center is a kind of CNC lathe that contains tool magazine and can change tools automatically, and can carry out a variety of machining operations on the workpiece within a certain range. In the machining center on the processing of parts is characterized by: the parts to be processed after a clamping, CNC control system can control the machine tool according to different processes automatically select and replace the tool; automatically change the machine tool spindle speed, feed and tool relative to the workpiece trajectory and other functions, continuous to the workpiece surface automatically carry out punching, countersinking, reaming, boring, tapping threads, cutting and othercheap cnc machining multi-process processing. Because the machining center can gather and automatically complete a variety of processes, avoiding human errors, reducing the workpiece clamping, measuring and machine tool adjustment time and workpiece turnover, delivery and storage time, greatly improving the efficiency and accuracy of processing, and therefore has good economic benefits. Machining center according to the position of the spindle in space can be divided into vertical machining center and horizontal machining center.

CNC technology and equipment is the enabling technology and the most basic equipment for the development of high-tech and top industry in emerging countries. Information industry, bio-industry, aviation, aerospace and other national defense technology around the world generally choose CNC technology to improve the manufacturing capacity and level, to enhance the adaptability of the market and competitiveness. Industrial developed countries will also include CNC technology and CNC equipment in the country's strategic materials, not only vigorously promote their own CNC technology and its industry, but also in the "high-tech" CNC core technology and equipment to our country to implement a ban and limited additive manufacturing rapid prototypingpolicy. Therefore, the vigorous promotion of CNC technology as the core of advanced manufacturing technology has become the world's developed countries to speed up economic development, enhance comprehensive national power and national status of the important way.

Why is it simple to process aluminum?

Due to its tendency to chip and relative ease of shaping, aluminum is more machinable than some other metals. When a material "chips readily," it indicates that it is more "free machining" and that the cutting tool is exerting more effort to cut the workpiece rather than the chips it has just produced.

How simple are CNC devices?

Using the instruction manual, assembling the machine is fairly simple. In addition to helpful features like z-axis capabilities, it provides a programmable cut depth. In addition to hard plastics, plywood, and MDF laminate, the Maslow CNC wood carving machine is strong enough to cut out shapes from a variety of other materials as well.

Which two prototyping methods are there?

Low-fidelity prototypes and high-fidelity prototypes are two categories for prototyping approaches and procedures. The type of prototyping method you use will depend on the resources at your disposal and the intended use of the prototypes.
