FREZY TRZPIENIOWE Z WĘGLIKÓW SPIEKANYCH MOULD AND DIE INDUSTRY NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING / 117 ELECTROPLATED MOUNTED PINS Electroplated mounted pins have three distinct advantages. Various special profiles can be manufactured to customer specifications and small head diameters from 0.4 mm are producible. Furthermore, distinct grain protrusion of diamond and cBN grits ensure high material removal rates. Apart from the extensive stock programme, various profile pins are available at short notice (see profile examples below). Please include the dimensions for D, T, S, S1, R, V and L2, when ordering. For spherical pin, the head length ‘T’ should be specified as ‘0’. The front face of the head of electroplated mounted pins from 6 mm diameter and above is specially designed to reduce the contact area. Minimum order quantity for manufacture of non-stock items: 5 pieces per item.
