Yesterday, my friend asked me what is the use of invisible clothing. What is invisible clothing? The Xiaobian of the rivers and lakes is covered, is there such a magical thing? My reaction is whether there are invisible clothes and whether there are invisible wings. This has not been invented yet. Later, Xiaobian consulted with the technical consultant of Beimai. The original Xiaobian was too naive to understand the mistake. Car invisible clothing is actually a car care beauty. A new type of environmentally friendly film. This is also a transparent lacquer protective film. The benefits of invisible clothing : 1. It has the advantages of all polishing and waxing as well as automotive coating. 2, the wear resistance is relatively high, for light scratches, collisions can be resisted. 3. Improve the brightness of the car package by 30. 4, high temperature resistance 150 degrees low temperature -80 degrees. 5, green and environmentally friendly, good ductility. 6, feel good, easy to clean. 7, do not worry about other people borrowing the car, give the car a better protection, and also have a face to open. 8, do not have to go to the 4S shop to paint repeatedly, saving a lot of money for painting. 9, elastic memory repair function, scratches will be automatically repaired when scratched. It can be repaired with a buffing gun and polished mechanical friction, which is faster. Disadvantages : 1. The price is high and the construction is cumbersome. It usually takes three days to complete a car. 2. In the event of a major accident, the membrane must be completely torn off, and the insurance company does not pay compensation. 3, tearing off the car paint damage. How to buy : Look at the malleability, generally good ductility is better. Can smell through the smell, bad will have a heavy smell. Look at its transparency, good will only brighten the body color, it will not make the body look foggy. Do you think the car invisible clothing is necessary? In fact, for those who just bought a car, they are very distressed, and they are afraid of having a flaw, or they have bumped into it. That is anti-collision, anti-automobile surface oxidation, this can separate the paint from the air. In fact, Xiao Bian feels that it is still very practical, but also depends on the price. We usually maintain the waxing effect of the car for several months. One hour of car coating time is one or two years. This is a long time than the car coating, which can be used for five years. Therefore, if you feel good, you will not do it if you feel bad, and everything will look at your own wishes.
Machining is a process that accurate to
remove material by mechanical machining technology.
The main classification:
Step of working out process regulations:
1) Calculating annual
production program, determine the type of manufacture.
2) Analysis part drawing
and the product assembly drawing.
3) Select blank.
4) Formulation process
route.
5) Determine the
machining allowance of each process, calculating the dimension and tolerance.
6) Identify the equipment
used in each process and cutting tool, jig, measuring tools and auxiliary
tools.
7) Determine the cutting
dosage and man-hour quota.
8) Determine the main
process of technical requirements and test methods.
9) Fill in the process
documents.
The production of CNC Machining Part, metal machined parts

Mechanical processing have manual processing
and CNC machining two types. Manual processing is means machining
various materials by mechanical workers manual milling machine, lathe,
drilling machine and the sawing machine and other mechanical
equipment. Manual processing is suitable for small batch production,
simple parts. Numerical control machining (CNC) means the mechanical
workers use numerical control equipment, the CNC equipment including CNC
center, milling center, wire cutting equipment, thread cutting machine,
etc. The vast majority of the machining shop machining the parts by
numerical control machining technology. Through programming,
coordinates the parts in the Cartesian coordinate system (X, Y, Z) into a
programming language, the CNC controller of numerical control machine by
identifying and explain programming language to control the axis of CNC machine
tools, automatic removal of material, get the part according to the requirement
and finish machining. CNC machining in a way that is straight artifacts, suitable for
mass and complex shape parts.
