Gantry milling machine _ Chen Hua Machinery (certified) _ gantry milling provided by China Machinery Equipment Co., Ltd. Qingdao Chen. Qingdao Hua Chen Machinery Co., Ltd. (www.qdchenhua.com) is specialized in the "press, ports bollard, adjustable multi-axis tapping drilling machine, CNC multi-axis drilling, milling goal" of the enterprise, the company adhering to the "integrity management , hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Yuan Xi Chuan. Vertical lathe spindle perpendicular to the horizontal plane, the workpiece clamping in a horizontal rotary table, knife move on the beam or column. Suitable for processing large, heavy, difficult to install on the lathe workpiece, generally divided into two major categories of single and double column. Relieving lathes at the same time turning radially gantry milling, turret-cycle reciprocating gantry milling cutter for forklifts, hob etc. forming the tooth surface. Usually with a shovel grinding attachment, by a separate motor-driven small shovel teeth grinding wheel surface. Specialized lathe lathe is used for processing certain types of specific surface of the workpiece, such as a lathe crankshaft, camshaft lathe, lathe wheels, axles lathes, roll lathes, lathes and ingots. Combined lathe is mainly used for turning, but add some special parts and accessories after, but also for boring, milling, drilling, insert, grinding and other processing, with "a machine can" feature, for engineering vehicles, ships or mobile repair work on the repair station. Accuracy refers to the movement of the drive transmission chain between the machine each end piece coordination and uniformity. Refers to the machine tool stiffness to resist deformation under external force capacity gantry milling machine rigidity, the higher dynamic accuracy. The stiffness of the machine tool comprises a contact member itself stiffness and rigidity member. Machine element itself depends on the stiffness of the material properties of the member itself, cross-sectional shape and size. Contact stiffness between the members not only contact materials, geometry and contact surface hardness, but also on the surface roughness of the contact surface, geometric accuracy, processing methods, media contact surface, the pre-pressure and other factors. Vibrations appear on the machine, forced vibration and self-excited vibrations can be classified. Self-excited vibrations are not subject to any external force in the exciting force interference, continuous vibration generated by cutting internal processes. Under the continuing role of vibration exciting force gantry milling and boring, the system is forced to forced vibration caused. Stiffness and damping characteristics of the shock resistance and machine tools, and quality related. Since the various components of the different coefficients of thermal expansion machine, thus resulting in different portions of the machine deformation and relative displacement, a phenomenon called thermal deformation of the machine tool. Errors due to thermal deformation generated maximum of 70% of all errors. For dynamic precision machine tools, there is no uniform standard, mainly indirect dynamic accuracy of the machine to make a comprehensive evaluation of typical parts by cutting accuracy achieved.
