Mold Polishing the defects may occur during and solutions

) High quality: The ABC Company is customized according to European standards KEMT imported European Spindle (0.001mm or less), screw (C3 level), the spindle bearings are used before and after the ultra-precision bearings, the unique structure of the rigid main shaft to ensure that the spindle high-speed and stable operation, which is characterized by the rotation to provide high precision and high torque, compact structure, light weight,[link widoczny dla zalogowanych], small inertia for fast starts and stops, vibration and noise, easy to control,[link widoczny dla zalogowanych], continuous time processing, maximum spindle speed of up to ~ Jd000rOm. (2) High rigidity: a unique bed base is made of high-rigidity cast iron structure of the whole, after a long period of natural aging, long-term use of deformation, to ensure the processing of security, speed and gravity for cutting, the overall rigidity, vibration absorption and strong, the structure stable for a long time continuous processing. (3) High precision: the structure using high-precision linear guides for cutting speed and gravity, good stability. Precision Ball screw imported from Europe (C3 level), precision ball screw drive efficiency above 99%, while the preload on the ball screw to compensate for thermal expansion and the elimination of inter-axial screw and nut gap, the drive to obtain the necessary high rigidity, so that the machine to obtain a high positioning accuracy and repeatability of positioning accuracy. (4) high life: all linear guides and ball screw are given automatic lubrication, to effectively improve the service life extension of the machine. States die polishing process lay in the possible settlement and the method of export documents must ■ / professional mold polishing factory in Suzhou Dongsheng 1 ▲ fine mirror polishing process Council is a major problem in the so-called Instead, the rougher the surface. This is mainly there are two phenomena that have a Been thrown in the machine polishing problems generally arise when the hand-polished cast over the phenomenon is rarely seen. Dongsheng mold polishing work in practice to take the following approach: (1) orange peel-like problems. Polishing pressure is too large and too long, it will happen. Softer materials more likely to have been polishing this phenomenon. The reason is not defective steel, but the polishing force is too large, resulting in mold steel surface due to small plastic deformation. The solution is: by nitrogen or other heat treatment to increase surface hardness of the material, and continue polishing liquid cooling spray (WD rust solution can replace a 40). Soft steel used for soft polishing tool,[link widoczny dla zalogowanych], and reduce the role of static pressure is the pressure on the workpiece the lighter the better. (2) pinhole problem. Because the material contains impurities in the polishing process,[link widoczny dla zalogowanych], these impurities out of the organization down from the metal to form a pinhole-like pits known as Solution is: to avoid the machine with aluminum diamond polishing paste. Done in the shortest appropriate time under the pressure of the polishing or mold using high quality alloy steel mold. Special emphasis is needed in the mold of all the polishing process,[link widoczny dla zalogowanych], the cleaning is essential. State 1o 2009 (Total 102】 MOULD & DIEPROJECT Die Engineering 55
