How to properly handle NSK imported bearings

     Due to the high precision mechanical parts of the rolling bearings, they must be handled accordingly. Even if the use of high-quality NSK bearings is not properly handled, its expected benefits will not be realized.
The main precautions should be observed as follows:

Keep NSK imported bearings and surrounding areas clean
Dust and dirt, even if the eyes are invisible to the naked eye, have a detrimental effect on the bearing. To prevent dust and dirt from bearing and keep its environment clean as an entry point.
Handle with care
Handling heavy impacts can cause bearings to be scratched or damaged and can cause their failure. Too strong impact can cause damage or cracks.
Use the right tools
Always use appropriate equipment to handle NSK bearings and avoid general purpose tools.
Corrosion protection
Due to the sweat of hands and other various contaminants, it may cause corrosion, keep hands clean, and then handle NSK bearings. Wear gloves if possible. Pay attention to the corrosive gas of the rustproof bearing.

What should I pay attention to when choosing a stone engraving machine?

1. To understand the performance and function of the stone engraving machine motor, the engraving machine manufacturer recommends that the engraving head motor of the engraving machine is also very important, because the engraving head motor is generally not covered by the warranty, and the engraving head motor is continuously working for a long time. Therefore, if the engraving head motor is not good, it will affect the use of the engraving machine.

2, should pay attention to the function of the stone engraving machine, the engraving machine of the engraving machine has high power and low power. Some engraving machines are only suitable for the processing of two-color boards, architectural models, small signage, three-dimensional handicrafts, etc. This process has been popular for some time, but the engraving power is too small and greatly affects its application range. The other is an engraving machine for high-power engraving heads. The engraving machine is divided into two categories, one is a large-format cutting machine: the width is generally more than one meter, but the precision of this engraving machine is generally poor; The class is a medium-sized engraving machine: this engraving machine is generally used for fine processing and organic sign making.

3, the other is the adjustable speed range of the engraving head motor, the general speed adjustable range is several thousand to 30,000 revolutions per minute, if the speed is not adjustable or the speed adjustable range is small, then the application range of the engraving machine is It is very limited because different materials must be rotated with different engraving head speeds.

4, the engraving machine body manufacturing process: high-power engraving machine work requires the body must be precise and stable, so long-term high-power engraving should use the casting body to ensure its processing accuracy and stability.

5, the controller is generally divided into two categories: one type of controller is only to do the drive, and all its calculation work is done by the computer. When the engraving machine is working, the computer is in a waiting state, and the typesetting work cannot be performed. Another type of controller is controlled by a single board or a single-chip microcomputer. This controller is actually a computer, so as long as the engraving machine starts working, the computer can immediately perform other typesetting work, especially
