XD-DX1860 moving column milling machine features a face, pallets using screw drive. Lubricated using automatic electric gear pump, can supply the fuel cycle time and downtime, respectively, to control, to achieve intermittent fuel cycle. 2 Head Boring Head rail using a complex, three pallets screw automatic oil lubrication, lubrication oil immersion milling head, column guide screw with manual or automatic lubrication. Machine has good antifriction lubricating properties . 4, column rails using super audio quench processing .. mainly rough castings are used before aging treatment (twice aging), the castings can eliminate stress, to ensure the stability of precision. machine castings are made of HT250 material. Rail surface hardness after quenching: Rockwell hardness 48-52 degrees. Improve the wear resistance of the rail, extending the life of the machine. 5: The machine structure is characterized by: imitation floor type boring milling styles improvement. Rails using double flat rails. After a rail grinder treatment, one can guarantee straightness precision, the second is to ensure the rail finish. http://www.xdjczz.com/category/lzdmxc/
