Products

1, the functional description:
Given column / moving column gantry milling machine is mainly used for medium and large cars cold stamping die and aviation, aerospace industry, equipment manufacturing parts and more sophisticated variety, small batch processing. Meet the usual milling, drilling, tapping, boring, bore, cylindrical, flat, level, cone, sphere, groove, and 2D or 3D complex surface kinds of high temperature alloys, titanium alloys, heat-resistant alloys, stainless steel, cast iron, cast steel and other materials, castings and forgings, rough pieces of the rough, finishing. Equipment, reasonable structure, stable and have sufficient rigidity and strength, the system powerful, reliable, high precision, long life. Reliable and stable high-precision processing difficult materials to complete all kinds of rough, finishing, surface complex parts machining. A fixture of the workpiece can be achieved roughing, semi-finishing and finishing.
Machine tool design and manufacture meet the ISO international standards, and passed ISO9001 international quality certification and CE safety certification. All parts and various machine tools of measurement instruments used in all unit element Yuan Yuan standard international units.
2, structural features:
2.1 fixed column / moving column gantry milling and boring of the main structure are in the development process through the finite element analysis (FEA) simulation, and continuously improve the development process to identify and design problems, in order to achieve excellence, stable product quality, provide disdain performance with the industry and the high-precision machines.
2.2 body and rail
High quality bed from the FC30 cast iron casting molding, casting, power tempered by internal stress relaxation. The door to scientific and reasonable structure, high rigidity of the combination table to meet the large load-bearing. Using advanced modular design, the best analysis by computer 3D and verification, reasonable structure, function performance with integrity. Large size of the columns and beams have excellent rigidity and strength to ensure the stability of the machine the best.
Machine X, Y, Z axis each have a separate servo motor and drive, with a three-axis coordinate, can be three-axis linkage. X-axis linear guide with heavy-duty roller, feed stable, low friction and can withstand heavy cutting and running to ensure accuracy. Y-axis is also used heavy-duty roller linear guide, torque and weight can cut the resulting spindle head forward minus to a minimum. Z-axis with heavy-duty roller-type linear guide, to ensure that the spindle has an excellent rigidity and strength and the best cutting stability, with hydraulic weight of nitrogen, non-drop phenomenon.
Spindle and gearbox 2.3
German FAG P4 class angular contact ball bearing heavy duty best suited to cutting, with a high efficiency gear box, spindle speed of 6000rpm, the transmission efficiency of 95% or more. Spindle with a forced cooling system and gearbox cooling system, with monitoring devices to ensure long-term normal spindle lubrication and temperature constant.
2.4 Servo System
Three-axis high-precision ball screw screw with PMI C3 level, pre-tension screw to compensate for thermal deformation.
a. X axis and Y, Z axis feed with separate automatic lubrication system in place to ensure full lubrication.
b. Three-axis servo motor with absolute encoder plus mechanical protective devices, can increase the flexibility of the machine operation and reliability.
