Boring machine workbench casts a process in production in, commonly used raw material includes: All sorts of useless steel, auxiliary metal stuff, foundry returns, cast iron, what is the characteristic of these raw material? 1, HT200-250 of raw material cast iron: Cast-iron it is one of raw material with machine tool commonly used cast, boring machine workbench is cast choose by GB718-82 with cast iron. The standard presses chemical composition to be cast iron cent a certain number of groups, kind, class, but take no account of the quantity that contain carbon. The user chooses cast iron name according to the quantity that contain silicon, according to group of choice of the quantity that contain manganese, choose course according to the quantity that contain Hu , according to contain sulfur content to choose kind. Specific choice which kind of, want the requirement according to workbench of different boring machine. Silicon and manganese are not harmful element, can choose according to need. 2, when all sorts of metal stuff cast boring machine workbench, use metallic data even, wait like aluminous, magnesian, copper, zinc, lead, stannum, antimonial, nickel, manganese. Industrial bullion belongs to pregnant of bag of stuff of this kind of auxiliary metal and alloy. Alloy majority is supplied by metallurgy factory, also can be the prefab alloy that casts factory frit to make sometimes, can use it direct remelting and make working alloy. 3, foundry returns: Foundry returns basically is rising head of mould of boring machine workbench and workbench of useless old boring machine. Foundry returns must not have serious and rustily, smeary reach slimy arenaceous impurity, the foundry returns of different name should be classified pile up, do not get stiff chaotic. Otherwise, not only the composition of alloy fluid is controlled not easily, and the composition of a kind of alloy may be harmful impurity to another kind of alloy, if mutual the mechanical function that stiff chaotic may reduce boring machine workbench or occurrence problem. For example Taichun of boring machine job if the alloy such as interfuse aluminium magnesium may make boring machine workbench produces a needle, interfuse tellurium, bismuth stimulate what the row turns over graphitization not to have element, will make boring machine workbench forms white mouth organization.

The method of Com/ bore: The preparation before bore of grey iron cast, must install boring machine workbench smooth, firm of grey iron cast, otherwise bore can appear to be mixed askew unqualified circumstance, in bore while, broach can produce certain quantity of heat, broach can wear away quickly, be in so bore while must carry cold fluid to the cutting part of broach, the action of cold fluid is lubricant, those who raise bore of boring machine workbench is bright and clean degree. The operation of bore, when bore, boring machine workbench drills a shallow hole first, prevent prejudicial, if need the capable person of grey iron cast of bore,compare character hard, want to often take out broach, eliminate to cut bits, means blocks broach, if drill larger hole, want to use little bit to drill a small hole first, the bit with old reoccupy, lest broach damages, reduce the resistance of broach at the same time. In the bore on cant of boring machine workbench, must use first establish milling cutter to be washed on cant of grey iron cast give a plane, reoccupy bradawl head gets an alveolus, ability can use broach operation of the standard, such operations rise to tilt not easily, we encounter the method that different aperture wants to be illogical to solve. Ability assures the quality of aperture. Tap and set buckle, be called tap with the whorl inside tap cutting, the whorl outside be being made with screw die bore with a reamer is called set buckle.
