Learn About Valve Grinding Materials
This is the study product of the Valve Core Grinding Machine.
The material of the lap ought to be based upon the product of the unpleasant and also its properties. The lap material ought to have: fine as well as uniform microstructure, great sand-embedding performance, good wear resistance, enough
hardness, no deformation, and its hardness is softer than that of the rough parts. Normally, the materials for the
lap are as complies with cast iron, low carbon steel, copper, lightweight aluminum, lead, babbitt, glass, asphalt, natural leather, and so forth.
Common study materials of the Valve Grinder Devices:
Cast iron. Cast iron includes flake graphite, which has excellent wear resistance and lubricating homes, and also high strength; it also has the advantages of affordable and also simple handling. As a result, cast iron laps are used for grinding a selection of materials such as concrete carbide, solidified steel, non-ferrous metals, etc., and are likewise suitable for fining sand, sanding, and also sanding. Cast iron laps are made from gray cast iron and ductile iron, and the firmness is normally HB120 ~ 220. Cast iron laps guarantee top quality, while grinding is effective and also commonly used.
Copper. The copper has great durability as well as wear resistance, as well as is suitable for rough working of handling with a big margin and low roughness requirement. It can work as a low carbon steel lap, but the price is high, as well as it is rarely used.
Low-carbon steel. The strength of low carbon steel is larger than that of cast iron, as well as it can adjust to the slender round holes, tapered holes, strings, and so on, which are hard to grind actors iron. Low carbon steel is usually utilized as a rough product.
Aluminum. The aluminum structure is softer than copper and is suitable for soft steels such as copper.
Lead, babbitt. Suitable for brightening and also grinding moderate steel or various other soft products.
Glass. The glass texture is hard as well as weak, appropriate for the grinding and also brightening of workpieces, particularly the hardening of hardened steel.
Natural leather, felt, polyester textile. The soft structure is often used to polish the work surface, the polyester fabric is even, and also the lining is placed on a flat lap, and also the result of lapping and polishing is great.
Asphalt. The asphalt is soft in appearance and is made use of for grinding and brightening of glass and also crystal lights. It is likewise ideal for the ending up of hardened steel. The asphalt has strong flexibility to the work surface.
