Machine column
Specifications / Features
Machine column material: machine column material common for HT250, this material strength, wear resistance, heat resistance are good, good vibration damping, casting performance is superior, need to carry on artificial aging treatment. In addition to the often used as well as HT200, HT300 or ductile iron, according to different requirements of the work.Machine tool post processing requirement: Huawei machine tool post processing is mainly reflected in the rail surface precision and hardness, inspection standards and lathe bed guide rail surface is quite, generally not more than 3, rail hardness according to the different material, after the completion of the quenching respectively HT250----HRC46 - 50, HT300----HRC48 52, quenching depth 2.5-3mm
The function of the column of the machine tool: the machining center column is mainly to the main spindle box to play a supporting role, to meet the Z direction of the spindle. It is generally used in the design of the double column frame structure, which is fixed on the sliding seat for large and medium sized moving columns. Because the column is an important part of connecting with the main shaft and the bed knife, so it must be designed to get attention. In terms of the spindle, the correct installation column machining center for a qualified parts has a role can not be ignored, and post installation mainly reflect in the verticality and the work table.
