The lasts are completely processed including toe and heel support left after roughing as the grooves on their cone top are clamped by the patented hydraulic system. The grooves, milled by the auxiliary machines SL.PLG/SL.PLRG/SL.PLA, on the cone top of the last, instead of the traditional clamps on the toe and heel, realize the complete finishing of the lasts and eliminate the risk of the lasts deformation caused by pressure on the tailstocks. The independent interpolated axes enable, in a single cycle of average 4-6 minutes, to refine 1-6 pieces lasts under each rotation position.

It presents the highest level of the last machining with perfect integration of electronics, mechanics, programming and 5-axis computer numeric control system. Because of its precision and repeatability, not only traditional lasts but also technical lasts produced by SL.PLM series machines as the requirement of customers, can be processed rapidly, precisely and indentically to the customers or the engineers original without compromise of precision and position difference between sampling and mass production.
