The past two years, China's fastest-growing heavy-duty CNC machine tools, such as heavy-duty CNC gantry milling machine,cast bronze heavy duty floor milling machine, heavy duty vertical and horizontal lathes, and so the annual production and market consumption has been ranked first in the world.
From the international market, relatively heavy-duty machine tools not highly competitive field, this economy so that domestic enterprises in the heavy-duty machine tool market successfully implemented a number of import substitution.
(1) The development trend of heavy-duty machining center is a high power, high torque, high-hole complex, and complex surface machining capability. In the world to see, representing the highest level of heavy-duty machining center is the company's products in Germany Fort, North Germany, a machine is used .Fort technology.bronze bushing Heath (SCHIESS) compared with the Coburg machine, whether in power, torque, specifications basically equivalent, but Heath's spindle speed, high precision to maintain good, technically belongs to the world leading level. Compared with other domestic and foreign products, foreign re-cutting ability, high precision, and has many technical advantages, such as copying beam processing technology, Z-axis ram length of the compensation technique, dry bushing the goal framework of the X axis dual motor, three motor even the four-motor synchronization technology.
(2) Boring and Milling domestic manufacturers are: Kunming Machine Tool Plant, Qiqihar Second Machine Tool Plant, plain bearing the second machine tool plant in Jinan, Wuhan Heavy Machinery and so on. Boring and Milling Machine manufacturers abroad are: PAMA,sleeve bushing Italy, Germany Heath, Italy INNSEBERARDI company, the Czech SKODA companies. HORIMASTERHM3 standard products in addition to rolling plain of Kunming Machine Tool Plant complex rail, the Jie and Machine Co., Ltd. with linear guide rail,DU bushing the other major manufacturers are mostly hydrostatic guideway structure, static technology is relatively mature, HORIMASTERHM5 except Kunming Machine Tool Plant,bushing a rolling sliding compound rail, brass bushing the rest are static rails. Static pressure in the field of precision heavy-duty machine application is comprehensive, the advantage of stability and the overall machine rigidity,Mould guide plate the disadvantage is the relatively high manufacturing cost and difficulty. plasic bushing In addition, the market mainly from the structure of the spindle with the use of ram and to increase the scope and function of the machining needs.
