3. Put the steel tubes into the tempering furnace to do the stress relief annealing in convenience of the subsequent the processing.
4. Multi-roll straightening machine, with 10 straightening points, achieves the automatic rolling straight improving the efficiency greatly
5. Heat treatment to obtain work pieces with different properties by changing their internal microstructure or surface chemical composition.
6. Cylindrical degree can be controlled within 0.03mm and the surface roughness is up to 0.4 by honing with range:φ40mm-φ450mm and longest length: 12000mm
7. Machining processes to obtain high precision parts with complex shapes strictly according to the detailed drawings.
8. Electroplating production process fulfills the functional and ornamental requirements for coating work pieces of different dimensions according to specific application requirements.
9. Cleaning all the parts by automatic cleaning machine in the special solution and under special  temperature control effectively.
10. All the parts are assembled into complete cylinders according to the strict assembly instructions by skillful workers in dust-free workshop.
11. Do proof pressure and performance tests to check whether the cylinders can operate smoothly and stably under the specified pressure with no leakage and deformation.
12. Do the painting including high quality primer and topcoat to obtain beautiful appearance and protect  the cylinders against the anticorrosion.
13. Wooden pallet or boxes packing with plastic films wrapped on the surface, suitable for long-time sea transport

Velcro Disc

Velcro disc is an abbreviation of sandpaper, a customary name. Velcro disc is also sandpaper. It is a conversion product of sandpaper. Its shape is a positive circle. It is flocked with sandpaper roll , and then put it on the stamping machine for stamping with *** circular die. The stamped product is velcro disc.

Sanding disc can be divided into two types according to the lamination: back glue disc sand and back velvet disc sand (also known as self-adhesive disc sand and brushed disc sand). The fluffed disc sandpaper can be non hole fluffed disc sand paper or hole fluffed disc sand paper. The velcro disc with holes is convenient to discharge waste chips from the holes when grinding objects, so as to improve the grinding efficiency. There are other classification methods. For example, according to the size, the common disc sands are 100mm, 115mm, 125mm, 150mm, 180mm and 215mm in diameter, and the diameter area of disc sands that can be used is 23mm --- 235mm.

According to the sand surface of disc sand, the common ones are white sand disc sand, red sand disc sand, yellow sand disc sand, black sand flocking disc sand, blue sand disc sand, green sand disc sand, grid flocking sand. And classified from the raw materials of disc sand paper, velcro discs can be divided into aluminum oxide velcro disc, silicon carbide velcro disc and zorconia velcro disc. Aluminum oxide velcro disc can be divided into ordinary aluminum oxide velcro disc, calcined aluminum velcro disc and so on. The particle size of disc sand is usually divided into 40# 60# 80# 100# 120# 150# 180# 220# 240# 320# 360# 400# 600# 800# 1000# 1200# 1500# 2000#.

And the application of disc sandpaper is extensive. From the space shuttle to the mobile phones and computers we use, disc sandpaper is used in the production process. Some parts of the space shuttle need to be finely polished with disc sandpaper, and the fuselage needs to be polished with disc sandpaper before spraying paint, so that there will be no paint peeling. Take our common notebook computers for example. If they can have such a mysterious appearance color, they can't lose the fine grinding of disc sand. It is mainly used for polishing, furniture, hardware, electronic accessories. At the same time, the efficiency of disc sandpaper grinding products is very high, which is faster, more convenient and less loss than conventional hand sandpaper grinding; However, the round sand disc also has some shortcomings. At present, with the gradual improvement of the requirements for the surface finish of the ground workpiece, the requirements for the base of the round sand are also higher and higher.
