experiment procedure

l Fix the movable seat in the proper position according to the length of the roller.

2. Press the ball handle and insert the roller. Use two * to hold the center hole at both ends of the roller. Tighten the tightening handle to fix *.

3. Move the bracket to the desired position and fix it; install the dial indicator on the bracket and make micro contact with the tube.

4. Turn the tube body by hand for one week and record the amount of jitter at different positions. The final value of zui is based on the large value of zui.

Unit: mm

Precautions

l The place where the test bench is used and placed should be ventilated and dry, and should not be excessively humid.

2. It is strictly forbidden to impact and scratch during storage and use.

3, *, guide rails and other important parts and parts after use, wash with gasoline and apply anti-rust oil, not rust. The sliding part of the test bench should always be lubricated, but the oil layer is not too thick, so as not to affect the accuracy of the test bench. The oil mark should always be injected with lubricating oil.

4. After the test bench is used, apply a dust cover to prevent dust from falling on the guide rail and related surfaces to ensure the accuracy of the test bench.

Vitamin

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
