Sand press plate
Specifications / Features
Warwick pressure sand cast iron plate is to test a variety of precision parts of the face (with light gap method), repair all kinds of gauge block, industry and trade card measuring, optical another piece and measurement accuracy and the part flatness tool. Pressure sand flat do for repair of the gauge block only measuring instruments, it is good or bad, will directly affect the gauge block repair quality.Warwick pressure sand plate material for high phosphorus, alloy, ductile pressure sand flat. High strength cast iron HT150-300, working surface degree of hardness is HB170-350. After artificial processing (artificial annealing 600 degrees - 700 degrees and natural aging 2-3 years) of the cast iron platform, pressure sand plate heat treatment is reduced gradually in the stress, eliminate pressure sand flat part of the white tissue, improve the hardness and wear resistance of the sand flat working surface pressure, the precision and stability of the pressure sand flat, wear resistance.
There is a need to block repair or even a few blocks of sand with excellent effect of pressure sand platform. The so-called pressure refers to the effect of sand:
1, block sand, sand flat to block sand, embedded solid, durable.
2, sand pressing process is simple and easy to operate.
3, cutting sharp wear.
4, fix the gauge block is easy to achieve the desired surface roughness. Gauge to repair in a few seconds or tens of seconds to complete flatness and surface roughness, length changes in the amount and so on several technical indicators.
Pressure sand plate produced according to JB / T7974 99 standard, working face mining useful grinding process, grinding for parts, measuring repair. With this product after grinding the work piece surface roughness Ra is less than or equal to 0.08 mu m.
