Bulk Production of Toolholders

摘要

Previous articles described my prototype tooling system which included one insert holder. I subsequently bought a selection of inserts being three for steel with tip radii of 0.2, 0.4, and 0.8mm and two for aluminium with tip radii of 0.2 and 0.4mm - so 1 needed five more insert holders complete with pillars. I started with the pillars. Their height is the most critical dimension - they all need to be the same height so that the handle clamps tight in the same place. The M10 thread of the clamp has a pitch of 1.5mm which corresponds to 360 degrees of position variation. So .01mm variation produces (360/150 = 2.4) degrees variation. Some variation up to ten degrees or so would not be a problem.
