Case of electroplated diamond grinding wheel for cast iron

Cast iron is a common processed material in metal processing. Compared with steel, although its strength, plasticity and toughness are lower, cast iron is simple to smelt and low-cost. It has superior casting performance, high wear resistance, good shock absorption and Extremely high machinability and cutting performance.

Therefore, it has been widely used, such as machine tool worktops and lathe beds. Especially in the automotive manufacturing industry, the absolute usage is astonishing. It is used to manufacture various parts, including engine blocks, cylinder heads, differential cases, and shafts. , flywheel, brake drum and brake disc, etc.
However, when specifically processing cast iron materials, six major problems will arise:

① The problem of built-up edge is easy to occur

② The surface has a strong tendency to harden

③ It is easy to encounter trachoma and pores, leading to edge chipping

④ It is not easy to obtain a good surface finish

⑤ Processing burrs are prone to occur

⑥The chip breaking effect is poor and chip removal is difficult.
The grinder is a commonly used equipment in casting processing. There are certain dangers during use, and the selection of the grinding wheel is particularly critical.
For example: balance problems caused by unqualified grinding wheel manufacturing. An unbalanced grinding wheel will vibrate when running at high speed, which will affect the grinding quality and thus the casting quality; the size standards of the grinding wheel are not strict, causing matching problems between the chuck and the grinding wheel. , which will not only cause a waste of equipment and materials; but also fail to meet safety requirements and easily cause personal accidents. Therefore, choosing a suitable grinding wheel product can not only improve the quality of castings, but also reduce waste, reduce costs and avoid some safety accidents.

Moresuperhard changes the volume of diamond and the control of working layer density according to the different requirements for the surface finish of castings, and increases the grinding amount to the best state according to the needs. The maximum grinding amount can reach 3200g every ten minutes, and the sharpness changes during the service life. Too big.
Electroplated diamond grinding wheels are suitable for grinding, deburring and polishing ferrous metals: cast steel, cast iron, non-ferrous metals: cast aluminum alloys, aluminum-magnesium alloys. This product has high manufacturing precision, long service life, low single-piece processing cost, and It can be used under high-speed conditions, which greatly improves work efficiency. It solves the problem of grinding large workpieces (aerospace nacelles, ship hulls, wind energy blades, engine blades, composite pipes, etc.) and integrated deburring and polishing of workpieces with complex contours (various castings such as engine blocks and heads).

The customer had been using an electroplated grinding wheel before, but the reaction was to remove the sand too quickly, and the customer’s equipment is not a commonly used angle grinder. In fact, it is better to recommend electroplating. We recommend whether to use electroplating or brazing.
