Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a high-efficiency double-tool magazine vertical machining center. Background Art

[0002] The machining center is a highly automated mechanical processing equipment with the following characteristics: it has a tool magazine that can complete automatic tool changing. After the workpiece is clamped once, the machining center can automatically select the processing method, change the tool, automatically set the tool, automatically change the spindle speed and feed rate, etc. according to the pre-compiled CNC machining program. It can complete multiple processes continuously, reducing the time of auxiliary processes such as workpiece clamping, measurement and machine tool adjustment.

[0003] Most existing machining centers utilize a single tool magazine. When machining complex parts, this type of magazine can only accommodate a limited number and types of tools.

Each tool change requires a series of actions, including magazine rotation, tool grabbing, and release. This results in a significant amount of time wasted on tool changes, significantly reducing overall machining efficiency.
