Engraving and milling machine LGT400_A16S
Engraving and milling machine LGT400_A16S

The main shaft is one of the most important parts of the engraving and milling machine. The main shaft is a DC motor driven by a belt drive spindle. The speed can reach 25000RPM. However, since the life of the brush is about 300 hours, the motor or motor must be replaced. Brushes, such motors are characterized by large torques, but the accuracy of such motors is generally not ideal. The other type is the use of variable frequency brushless motor, the speed can reach 60,000 RPM, no need to change the carbon brush, using frequency control technology, is a professional-grade product!

The structure of the CNC engraving and milling machine:

1, the main axis

The main shaft is one of the most important parts of the engraving and milling machine. The main shaft is a DC motor driven by a belt drive spindle. The speed can reach 25000RPM. However, since the life of the brush is about 300 hours, the motor or motor must be replaced. Brushes, such motors are characterized by large torques, but the accuracy of such motors is generally not ideal. The other type is the use of variable frequency brushless motor, the speed can reach 60,000 RPM, no need to change the carbon brush, using frequency control technology, is a professional-grade product!

2, guide rail

Linear cylindrical guides are mostly used for small-format engraving and milling machines, and large-format engraving and milling machines are mostly linear square guides.

3, ordinary thread screw

It is the screw rod commonly used in general milling machines. The common screw has large frictional force and is prone to jam when it is easy to wear and wear at high speed.

Precision ball screw---Professional grade product is the most important and most expensive part in engraving and milling machine. The precision of engraving and milling machine is determined by it. Since the engraving and milling machine is bidirectionally driven, the ball screw is required to be pre-loaded. Pressure, there will be no gaps when it is reversed. The advantages of the ball screw are good precision, low resistance and long life. The way to distinguish the two types of screw is: the ordinary screw is generally black, and the thread shape is square or trapezoidal. The thread of the ball screw is semi-circular and the color of the screw is generally white.

4, transmission

1 wire drive, the material used is aviation wire, outsourcing a layer of engineering plastic called kepton (super high wear-resistant material, the wire of the cable-lined missile is coated with this material), high-strength engraving machine driven by such technology Cheap and fast, only for models with two-color plates;

2 steel belt drive, made of alloy material with a thickness of 0.1mm, similar in characteristics to steel wire, suitable for light large format machines.

5, floating cutter head

Engraving a two-color board often seems simple but actually not easy to do. The general user's idea is to require the manufacturer to provide a high-precision platform. Some manufacturers simply add a thick plexiglass plate to the platform, and use a knive to first mill a plane on it, but still can't solve the problem. Because in addition to the error of the platform, the two-color board itself has errors. The double-sided tape that attaches the two-color board to the platform also has thickness, and other factors, so that the carved signs are still different in depth.
