Instantly provide a variety of facades require horizontal and vertical datum

Laser marking instrument in recent years the rise of building renovation instrument, which replaces the traditional plumb line and the horizontal ruler and other tools, laser horizontal and vertical lines displayed directly on the wall, intuitive, clear, convenient and durable, and easy to carry. The product can be used indoors and  synthetic diamond powder  provide a variety of facades in an instant need horizontal and vertical datum. The instrument display, high precision, 10m angle error is less than 3s. Its working principle is as follows: laser transmitter emits laser → optical system focusing (aspherical lens) → formed by a cylindrical  Abrasive grinding wheel or vertical lines → enlarged display in the building. Part of the key parts for the product, high-precision bearing assembly in which two φ9mm the hole, a small shaft through which the laser emitting device then passes through this small axes hanging at the top. Thus, even if the floor is uneven which can also be achieved automatically find the positive balance. The machining accuracy directly affects the detection accuracy of the instrument. Paper and process analysis as part of the rough parts ADC12 die casting, die-casting high dimensional accuracy can be achieved IT8, angle accuracy and low surface roughness can reach 1.6um.
