Powder metallurgy oil bearing introduction

Powder metallurgy oil-impregnated bearings are generally formed at one time and are basically not machined. The cost is lighter than machining, the material waste is less, the price is therefore cheaper, and it is in line with the current national policy of promoting energy conservation, so it is considered to be a technology that will not fall behind.

The powder metallurgy oil-impregnated bearing has been filled with lubricating oil by vacuum impregnation in the base body, and the lubricating oil will seep out to the running surface due to temperature rise and pumping during operation, so it can be used without additional lubricating oil. The occasion.

Powder metallurgy oil-impregnated bearings (oil-bearing bearings) are a class of porous alloy products impregnated with lubricating oil in the pores. When the shaft rotates, the temperature of the oil-impregnated bearing rises and the pumping action is caused by the friction between the shaft and the oil-impregnated bearing.

The lubricating oil impregnates the friction surface containing the inner or outer diameter of the oil-impregnated bearing when the shaft stops rotating. The lubricating oil is returned to the inside of the oil-impregnated bearing. Therefore, the consumption of lubricating oil is extremely small, and it can be used for a long period of time without supplying lubricating oil from the outside, and is very suitable for the occasion of difficulty in supplying oil and avoiding contamination of lubricating oil.

Laser engraving machine engraving introduction

Engraving machine manufacturer laser engraving machine engraving introduction

The dot matrix engraving dot is like a high definition dot matrix print. The laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head simultaneously moves up and down to engrave a plurality of lines, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be carved using dot matrix.

Vector cutting is different from dot matrix engraving, and vector cutting is performed on the outer outline of the graphic. We usually use this mode to perform penetrating cuts on wood, acrylic, paper, etc., as well as marking on a variety of materials.

Engraving speed: Engraving speed refers to the speed at which the laser head moves. It is usually expressed in IPS (inches per second), which results in high productivity. Speed ​​is also used to control the depth of the cut. For a particular laser intensity, the slower the speed, the greater the depth of the cut or engraving. You can adjust the speed with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The advanced motion control system of the Hummer makes you get super-fine engraving quality when carving at high speed.

Engraving intensity: Engraving intensity refers to the intensity of the laser that strikes the surface of the material. For a particular engraving speed, the greater the intensity, the greater the depth of the cut or engraving. You can adjust the intensity with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The greater the intensity, the greater the speed. The depth of the cut is also deeper

Spot size: The laser beam spot size can be adjusted with lenses of different focal lengths. Small spot lenses are used for high resolution engraving. Large spot lenses are used for lower resolution engraving, but for vector cutting, it is the best choice. The standard configuration for the new device is a 2.0 inch lens. Its spot size is in the middle and is suitable for all kinds of occasions.

Engravable materials: wood products, plexiglass, metal plates, glass, stone, crystal, Corian, paper, two-color board, alumina, leather, resin, spray metal

Good cutter head breaks the bottleneck problem of carving agate jade in stone engraving machine

Jade carving machine, also known as computer jade carving machine, is an industry classification of stone engraving machine. It is a new type of numerical control equipment in recent years. His working principle is very similar to that of CNC milling machine. The engraving programming software is used to convert the content to be engraved into a standard G code that can be recognized by the engraving machine control software, and the three axes of the control machine are automatically moved in a jog-continuous manner to achieve the effect of automatic engraving. The jade carving machine can be used to engrave text or pattern on jade, such as sculpt, yang, line and emboss. It can also be applied to other engraving materials. Jade, jade, jewellery and mold processing. With the development of science and technology, the advancement of human understanding, the replacement of art by machines is an inevitable trend of social development. The retirement of the old stonemason and the pursuit of science and technology by young people made the jade carving machine come into being. More and more people pay attention to efficiency, pay attention to beauty, pay more attention to health, pollution-free, pollution-free CNC jade carving machine will become the main production tool in the stone carving industry.

     However, many processing factories that buy computer engraving machines can not only generate profit after buying the machine. Instead, they can only be discarded as scrap iron in the corner. Looking at the reasons for the embarrassment, the ambitious when buying the machine, the later can’t help. To put it bluntly, it is the problem of the knife head. No diamonds dare to take porcelain, many of them are not the head, the carving is not good, so I have to give up the machine to engrave agate, jade and other hard jade, but even if it is nephrite, it can not be carved. So there is no practical carving knife that can solve this bottleneck problem of computer engraving machine!

     Now there is a computer engraving machine knife imported from Germany, which has opened up this bottleneck. Whether it is carved nephrite, or carved agate, jade and other super-hard jade can be competent, many domestic computer engraving machine manufacturers take it as the preferred match. Machine tools, you may wish to try.

How to remove noise from stone engraving machine

Stone engraving machine---has maintained a strong vitality since the twentieth century, which has made China's engraving equipment develop rapidly and ranks among the world's largest stone engraving machine manufacturers. In the past two years, the export of stone engraving machines seems to have not been affected by the financial crisis, and it still maintains the momentum of continued growth. As a kind of numerical control tool, the stone engraving machine can easily complete accurate digital positioning and run smoothly, and the precision is more than ten times higher than that of traditional equipment. Especially when doing gravity stone arc, it shows the numerical control. The strength of the equipment is greatly convenient for the users. It is unmatched by traditional tools, so it is well received by the majority of stone users.
Here are some noise questions for the stone engraving machine:
The stone engraving machine generally uses a stepping motor. The stepping motor has a pause every step of the way, and the noise is normal. At a certain frequency, the stone engraving machine will also generate resonance of the body and emit obvious noise. This type of noise does not affect the normal use of the machine.
The noise that affects and is harmful to the stone engraving machine is mainly manifested in the following two categories:
1. The abnormality noise is emitted when the spindle motor of the stone engraving machine is running.
The generation of such noise proves that there is a quality problem in the spindle bearing of the stone engraving machine or the service life of the spindle bearing has arrived, or the quality is degraded or damaged after the wear, and the replacement can be considered at this time.
2. The stone engraving machine emits an abnormal sound when walking axially.
Stone engraving machines are mostly found on the X-axis. Mostly the axial motor bearing is damaged or the X-axis guide rail lacks lubricating oil, dirty, too tight, ball wear, ball drop, etc., must be handled in time.
