As the non-uniform countermeasure of abrasive grain impact marks is prevented, consider the length L of spray-hole 36 being set as handled object
More than 60 width, but the gap-shaped spray-hole 36 is longer, the concentration of the abrasive grain 50b in slurry 50 it is easier according to place and
Become uneven, it is difficult to maintain the uniformity of processing, and along with the enlargement of wet shot sand device, the problem of cost and need wide
Wealthy installation space etc. is simultaneously unrealistic.In the case where current functionization is horizontal, the limit of the length L of gap-shaped spray-hole 36 is
60cm or so.
