1. What is grinding.
Grinding refers to the process of processing the surface of the faucet by using the high-speed rotation of various grinding heads or linen (cloth) wheels of the grinding machine.
2. Abrasive belt grinding machine.
Refers to a grinding machine that grinds with a fast-moving abrasive belt.
3. Surface grinder.
Refers to the grinding machine mainly used for grinding the plane of the workpiece.
4. Grinding machine.
It refers to a machine tool that uses the high-speed rotation of the linen (cloth) wheel to grind the surface of the workpiece to make it smooth and bright, and to increase the brightness and finish of the product.
5. Brief description of the faucet polishing process.
First, prepare the grinding tools, abrasive material and abrasive belt, and adjust the machine. Rough grinding the faucet (No. 60 or No. 80) abrasive belt to remove rough surfaces and pits, use (No. 180 or No. 240) abrasive belt to make the surface fine, trim the contour, then (No. 320 or No. 400) abrasive belt is ground for 3 times, the surface has ideal appearance and clear lines, and the structure is evenly connected with No. 600 abrasive belt for finishing, so that the surface achieves the ideal appearance outline and becomes a real appearance entity. There are no obvious blisters and pores on the surface. Finally, 800 sand processing is carried out to make the surface clean. Or proceed to make the surface smooth and bright with smoother lines. During this period, all processes are inspected for the first time by quality inspectors, process inspections are carried out, after the inspection is completed, the signature is moved, and strict inspections are carried out to ensure the quality.
External plating
1. What is electroplating?
Refers to the process that the metal uses the action of electron flow in the electrolysis process to restore the metal cations in the plating solution to the metal element and deposit on the surface of the cathode electroplating.
2. Brief description of the electroplating process of the faucet.
The first is ultrasonic wax removal and cathodic electrolysis of oil. Oil electrolysis, activation, roughening, movement after recovery, neutralization, surface conditioning, pre-soaking, sensitization, acceleration, cation electrolysis, anion electrolysis, water washing, neutralization, acid copper, activation, cleaning, nickel plating, recovery, cleaning , chrome plating, etc. Copper plating can make the coating get a finer structure, small defects on the surface of the faucet, small pinholes, and small pores can be covered up to achieve satisfactory results. The effect of nickel plating can improve the corrosion resistance of the surface of the faucet, and it is highly polished. Chromium plating maintains brightness for corrosion resistance, improves surface hardness and improves wear resistance. The quality of electroplating surface treatment can be judged by 24-hour acetic acid salt spray test (the test equipment is a salt spray tester) and electroplating thickness gauge to identify the plating thickness of each metal. Usually the thickness of the coating meets the standard, and the salt spray test is qualified. The appearance of electroplating quality is fully inspected and recorded by quality inspection.
