  • 1.  Manufacture of cars and spare parts

    2.  Manufacture of mechanical parts and gearing

    3. Facilities for metal processing and accessories and functional parts of lathe

    4. Equipments of technics

    5.  Universal machine and metal molding equipment,

    Cane, air presser, valve, pump, fan, cooler, cool rolling mill, rivet machine, metallic products.

    6. Treatment of the surface

    This process include painting, brushing and plating, neatening, etc. the material used comprises metal and non-metal. Following are the equipments and material needing surface roughness testing.

    Painting equipments, brushing and plating equipment, surface cleaning equipment, protecting equipment, sandblast equipment,daubing equipment, surface fine-decorating equipment, silk ware, cast-steel power, nozzle, galvanized plate, painting surface of carriage.

    7. Metallurgy , rolling and forging equipment

    In this industry, the one concerned with the roughness tester is the metallurgy and rolling of steel, iron, copper and aluminum.

    8. Pneumatic and hydraulic elements and pressure vessel.

    Over high-voltage inner face, sealing loop, pat, cylinder, air valve, ball valve, Pneumatic and hydraulic pressure cylinder, air drum, alloy pump, tin pump, jack, powder metallurgy, hydraulic brake, general plate of valve, electric pump, oil pump.

    9. Foundry of mould, close manufacture

    Plastic mould, pressure mould, cover mould, founding mould, melting equipment, founding equipment, iron and aluminum cast, coloured metal casting, steel-casting, stainless steel casting,alloy-casting, close casting.

    10. Press, packing, light industry and spinning machine, and medical appliance.

    Roughness tester of press machine is mainly the testing of plate-making machine( PS plate), gravure roller. In spinning machine, the one needs the roughness testing is directing wheel of gauze, all kinds of core-shaft, alumina material, and close pottery-parts. The medical appliance industry is just one under-development in which testing is used in medical accelerator. What to be emphasized is in the application of high-quality web-printing, surface roughness tester is used to test the stencil. And in the plastic parking industry, surface roughness testing is essential to the glassy roller, who is one of the most important part in parking equipment.

    11. Petroleum, chemical engineering, coal and cement machine, and agriculture mechanism.

    For the petroleum machine, the inner and outer face of the high-precision pumping pipe which have special demand for surface roughness both need surface roughness testing. In addition, the roughness testing is also used in testing of some other parts of petroleum machine such as the pumping bar and sleeve of oil pipe. In coal machine, the inner face of hydraulic cylinder and the surface of hydraulic valve need the roughness testing.

    12. Grain and oil, food, beer machine and pharmaceutical machine

    The roller of flour-mill and the appliance of beer machine both need surface roughness testing. Additionally, storing pot, inner surface of the beer tin, the surface of electrothermal pipe used in the cigarette-maker are also involved in the roughness testing.

    13. Equipments of electric power, auto-control, electronic communication.

    In electric power and auto-control industries, roughness testing is generally used in the testing of high-voltage switch. And in the electronic communication industry, a high-tech one, roughness testing is extraordinarily necessary. Such as the magnetic band of IC card, copper foil connection, and so forth. In the same way, the production of semiconductor wafer also demand for the roughness testing.

    14. Aviation and space-flight business, military industry

    In these industries, roughness tester is usually used in the manufacture of plane, rocket, galley, steamship, guns, armored cars, and all that. Further more, the inner face of gun pipe, warhead, inner face of magnetic conductor used in radar.

    15. Universities, institutes

    In universities and institutes, roughness tester is often used in a laboratory as a studying object or works for the teaching.

    16. Paper-making business

    In a paper mill roughness testing of the paper is always the most important procedure , which will determine the quality of paper.

    17. Industrial pottery, prezoceramic, electric pottery.

    Pottery is newly material, nowadays, has been widely used in several industries. And accordingly, roughness testing is also necessary in these industries.

    18. Business of rubber, epoxy, polyethylene

    Normally, the rubber material, which is slippery and smooth, need some chemical and mechanical treatment to increase the roughness, and certainly needs roughness tester.

    19. Canal of liquid, compound glass fiber silence-tube

    Ripple expansion, cyclone, These special tubes usually need the testing of inner and outer surfaces,

    20. Alloy doors and windows, handle of door, parts of chair, surface of stainless steel cup and dishware, exterior of taps.

    21. Crystal, carborundum, graphite, film of diamond, magnet.

    These special materials need testing of their surface roughness.

    22. Chromeplating battery,canister of telescope.

    They are both made by a new material which can combine tightly and has a really rough surface. It is the ideal material for high-power enormous capacity battery

    23. Copper-foil stationry, hard alloy ball, base for ball, auto-pencil lead.

    The hard alloy ball and base for the ball of the ball-pan point both need the testing of surface roughness.

    24. Medical nursing

    Usually in the medical nursing, patients’ teeth, skin and even the connecting plate for bones are all need the roughness testing.

    25. Clothing-making machine

    clips for the hooks to test the shoes comprise clips and loading holders, in which there is a pin, who needs testing of roughness.
