According to different functions, cnc milling machines can be divided into economic type, fully functional type, high-speed type, and engraving type. In recent years, economical cnc milling machines have gradually withdrawn from the market. So today, let's introduce the fully functional type, high speed type, and engraving type milling machines.

Fully functional cnc mill

The cnc system of a fully functional cnc milling machine generally adopts the cnc system with rich functions produced by professional manufacturers. The control part often adopts semi-closed-loop or closed-loop control. It is one of the CNC machine tools widely used in actual production. It has a wide processing range and strong processing adaptability. This kind of cnc machine tool can also be equipped with cnc rotary worktable to expand the three-axis cnc milling machine to a four-axis function.

High-speed type cnc mill

High speed milling is one of the development directions of cnc machining. Its technology has been basically mature and gradually applied in production. This cnc milling machine adopts a new machine tool structure, functional components and powerful cnc system, and is equipped with advanced tool system and tools. The spindle speed is generally 8000-40000 r / min and the feed speed can reach 10-30 m / min. it can process complex curved surfaces with high efficiency and high quality.

The main problem is that the price and maintenance cost of machine tools are high, which limits its application to a certain extent. The design scheme of high speed milling cnc milling machine often appears in the form of machining center, and the number of working axes is up to five axis linkage.

Engraving type cnc mill

Engraving cnc milling machine, also known as engraving and milling machine, is a cnc milling machine specially designed for engraving processing. It is generally a three-axis linkage control scheme. It is often used to process art products such as relief, pattern, pattern and so on.

Because the diameter of the engraving tool tip is very small (as small as 0.1mm), and the processing mode of small cutting depth and fast walking tool is generally adopted, the processing power consumption is not large, so the high-speed electric main drill is often used, the high spindle rotation speed is up to 24000r / min, the applicable tool diameter is generally no more than 12mm, and the engraving machine has high spindle speed of high speed cnc milling machine fast feed speed. However, its spindle power, machining accuracy and clamping tools are not as good as high speed cnc milling machine, and the main advantage is affordable.

Relationship between cnc milling machine and machining center

Cnc machining center, referred to as machining center for short, is a new and efficient cnc machine tool developed on the basis of cnc milling machine. It adds tool magazine and automatic tool change device on the basis of ordinary cnc milling machine. The function of machining center in hole processing (drilling, reaming, boring and tapping) has been further improved.

The tool magazine of the machining center mainly includes disc type, hat type and chain type. There are two kinds of tool changing methods in machining centers: manipulator tool changing and spindle tool changing. Manipulator tool changing is widely used, and manipulator tool changing is generally used in disc and chain tool libraries.
