Is the Foton level better or the Lesai level

It is said that Fukuda is good.

Spirit level. The working surface is not allowed to have a convex phenomenon, and its flatness.

It should comply with the provisions of Table 6-10-54. The length of the working face is 150 200 250 300, and the flatness deviation is < For the grinding and grinding working face, the flatness is not less than the length of the inspected surface with a zero-level knife edge ruler.

The verification is carried out by the light gap method, which should be carried out in the longitudinal, transverse and diagonal lines of the working face.

The direction of several positions is carried out. The maximum clearance seen is the flatness deviation of the surface. When estimating the gap size, a standard gap consisting of gauge blocks can be compared.

Main types:

Bubble level is to check whether the machine installation surface or flat is level, and to measure the direction of inclination and the size of the angle of the measuring instrument, its shape is made of high-grade steel frame, after precision machining, the base of the frame must be flat, the seat surface ** is equipped with a longitudinal circular shape of the glass tube, there are also attached to the left end of the transverse small horizontal glass tube.

The tube is filled with ether or alcohol and leaves a small bubble, which is always at the highest point in the tube. The glass cylinder has a scale on both ends of the bubble. Usually, when installing machines in factories, the sensitivity of a bubble level is commonly used to be equal to and equal specifications.

Laser line projector, now the quality of infrared is greatly reduced, reducing a lot of cost, you can buy it within 100 yuan, of course, the probability of bad is large, and the repair rate is very high. All things considered, it is recommended to buy a green light level, which is very good in terms of quality and repair. TB, Xuanhao Optoelectronics, you can take a look, it's pretty good.

Foton is a regular manufacturer, but ordinary levels can meet the general use.

In fact, it doesn't matter what brand to buy, Foton, and Laisai are good, but no matter how good the manufacturer is, there are defective products, the key depends on the after-sales service, these two do not have three packs, only repair not replaced, but buy a level to be optimistic about after-sales service, Zhejiang has a good three packs, warranty replacement (Zhejiang's Bendeli, Smeron).

It is said that Futian is good, I spent 350 yuan to buy a green light 2 line, so many people can not use it in front of it, I went to the store and ran four times, delayed for two days, and I have to borrow it, we should pay attention when buying, look good, try it well, otherwise we can't afford to miss it!

On the whole, Laisai is the best and the accuracy is guaranteed. Futian's, there are also low-end goods, so it's better to buy miscellaneous machines, anyway, it's a bargain. But Foton's high-end goods can still be PK with Laisai, and the quality is also very good, much better than miscellaneous brands.

It depends on how much you spend. In addition, for miscellaneous manufacturers, will say that the after-sales is replaced, that is, garbage goods, the goods returned, the factory is not refurbished and then sold, the factory is not a nerd, not dismantling accessories, and then assembled, I think that Foton and Laisai only repair not replace better, long-term at least every time you buy all new machines, not miscellaneous brands of those for new, just buy new shell machines, which are full of old machine refurbished goods.

LyseySpirit level. Stronger light than other brands of levels.

A spirit level is a commonly used measuring tool for measuring small angles. In the mechanical industry and instrument manufacturing, it is used to measure the angle of inclination relative to the horizontal position.

The flatness of the guide rail of the machine tool equipment.

and straightness, horizontal and vertical position of equipment installation, etc.

According to the different shapes of the level, it can be divided into: universal level, cylindrical level, integrated level, mini level, camera level, frame level, ruler level; Press level.

The fixation method can be divided into: adjustable spirit level and non-adjustable level.

A spirit level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rail of machine tool equipment, the horizontal position of the equipment installation and the vertical position of the dust before the vertical position, etc.

According to the different shapes of the level, it can be divided into: frame level and ruler level; According to the fixing method of the level, it can be divided into: adjustable level and unwise cover Zen adjustable level.

The spirit level is mainly used to check the straightness of the guide rail of various machine tools and other types of equipment and the horizontal and vertical position of the equipment installation.

It can also be used for measuring small angles and working surfaces with V-grooves, as well as for measuring the mounting parallelism of cylindrical workpieces.

As well as the horizontal and vertical positions of the installation. A spirit level is a mechanical device installation that measures horizontality and verticality.

An indispensable precision measuring tool.
