3 water chestnut roll out 4 cooling aperture hard alloy broach
From;    Author:Stand originally
Companies of 3 tool of water chestnut material roll out broach of hard alloy of a whole recently -- " efficient treatment aluminium alloy uses WSTAR bit " , its characteristic is: Broach has 4 cooling opening, use a fluid to emulate a technology to determine the optimal distributinging position of 4 cooling aperture, according to the characteristic that efficient bore machines aluminium alloy, undertook optimizing designing to getting channel and cutting blade figure, make the axial thrust of broach reduced 5 % ~ 15 % , the efficient bore of the aluminium that can come true to stick a knife easily and aluminium alloy workpiece is machined.
