Title:
GRINDING METHOD OF MATERIAL SURFACE
Document Type and Number:
Japanese Patent JP3113746
Kind Code:
B2
Abstract:
PURPOSE: To secure such a ground surface as excels in smoothness with no grinding irregularity in an efficient manner by reciprocating a grinding nozzle, set up in a relative feeding direction between a material and this nozzle, in the relative feeding orthogonal direction beyond the material surface width, and grinding the work into being almost smoothened.
CONSTITUTION: Plural pieces of abrasive water jet nozzles 2 capable of reciprocating up to the outward of each edge at both sides of a strip work W is formed into an multinozzle block 1. In succession, this strip work W is shifted in an arrow U direction, and this multiblock 1 is shifted in a cross direction at a scan stroke W2 larger than width W1 of the strip work W, whereby the locus forms a scanning pattern. Thus, each nozzle 2 of the multinozzle block 1 is tuned over at the outside of each edge at both sides of the strip work W, and thereby there is no turnover point formed in the point midway in the width. Consequently, grinding concentration on the turnover point by the nozzle 2 is eliminated, so that any grinding irregularity is preventable from occurring.
