Multifunctional cutting device with ultra-high cutting linear velocity

Abstract

The invention provides a multifunctional cutting device with ultra-high cutting linear velocity. The multifunctional cutting device comprises a first motorized spindle, a second motorized spindle, a turning tool holder and a base, wherein a fixed workbench of the first motorized spindle, a movable workbench of the second motorized spindle and the movable workbench of the turning tool holder are arranged on the base, the movable workbench of the turning tool holder is positioned at the front, and the first motorized spindle is fixedly mounted on the fixed workbench of the first motorized spindle; the second motorized spindle is fixedly mounted on the movable workbench of the second motorized spindle; the first motorized spindle and the second motorized spindle are coaxial and oppositely arranged; and the turning tool holder is mounted on the movable workbench of the turning tool holder. According to the multifunctional cutting device disclosed by the invention, a cutting tool and a workpiece are respectively mounted on the two sets of the motorized spindles, which are coaxially mounted, and the rotation directions of the two sets of the motorized spindles are reverse so as to increase the relative cutting speed of the cutting tool relative to the workpiece by times; and simultaneously, the multifunctional cutting device has a variety of cutting functions, such as ultra-high-speed milling of end surfaces, ultra-high-speed boring of inner circular surfaces, ultra-high-speed turning of outer circular surfaces and the like.

Description

Technical field [0001] The invention relates to a multifunctional cutting device capable of realizing ultra-high cutting linear speed, and belongs to the technical field of metal cutting machine tools. Background technique [0002] High-speed cutting technology is currently the most cutting-edge technology in the field of machining. High-speed cutting has: metal removal rate is 5-10 times higher than conventional cutting, cutting force is about 30% lower than traditional cutting, cutting deformation is small, the processed surface has lower cutting heat, easy to achieve vibration-free cutting, and low finishing cost And many other advantages. [0003] With the deepening of research on high-speed cutting technology, there is an increasingly urgent need to achieve higher cutting linear speeds. At present, increasing the spindle speed and increasing the effective cutting diameter of the rotary cutting tool or the rotary workpiece are the fundamental ways to achieve higher cutting li...
