The detection device we are talking about here refers to a position detection device used on a numerical control machine tool. They are usually installed on the workbench or screw of the machine tool, which is equivalent to the dial of the ordinary machine tool and the eyes of the person. The displacement of the worktable is continuously detected and fed back to the control system. A large number of facts prove that for a well-designed high-precision CNC machine tool, its machining accuracy and positioning accuracy will mainly depend on the detection device. Therefore, the precision detection device is an important guarantee for high-precision CNC machine tools. In general, the detection devices used on CNC machine tools should meet the following requirements: (1) Reliable work and strong anti-interference. In general, the detection accuracy of the detection device is 0.001~0.01mm/m, and the resolution is 0.001~0.01mm/m, which can meet the requirements of the machine tool table to move at a speed of 1~10m/min.

Paper tube round box is one of our unique
shape of the boxes. In general, it is used to the candy packing, candle
packing, cosmetic packing, and underwear packing. The paper tube round box as
the candy box, there are display window and decoration ribbons. When it used to
the candle, maybe just do the base without lid. If as the cosmetic box, paper
tube round box will be luxury and exquisite appearance. The white paper tube
round box especially suitable for close-fitting clothes, give a person the
feeling of clean.
The candy and candle packing are usually
made of coated paper, white cardboard. The size is smaller. Looks like very itsy-bitsy.
Make the person can't help to have the urge to buy candy. Would you be want to experience
the charm of it?
The material of cosmetic box and underwear
box is high-quality grey cardboard and art paper. It make the paper tube round
box into the luxury gift box.

(2) It can meet the requirements of precision and speed.
(3) Easy to use and maintain, suitable for the working environment of the machine tool.
(4) Low cost.
Table 4-1 is a detection device that is currently used on CNC machine tools. This chapter introduces some of the commonly used ones.
