Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutter heads, in particular to a novel milling cutter head. Background Art

[0002] The milling cutter head is a key component in the milling process, which determines important performance such as processing accuracy, surface quality and tool life. There are many types of milling cutter heads, including flat milling cutters, ball end milling cutters, taper milling cutters, end mills, spiral end mills, corn milling cutters, flying cutters and other types, which are suitable for milling of various complex geometric shapes and materials. Most common milling cutter heads are composed of a single type of milling cutter, which can only operate the milling process of a single requirement. When the demand is changed, the milling cutter needs to be replaced separately. At this time, the operator needs to shut down the equipment and select a suitable milling cutter for replacement. This process may take different times depending on the proficiency of different operators, which may delay normal production tasks and cannot adapt to the current high-efficiency production environment.

[0003] Secondly, due to their complexity, some parts require frequent replacement of two milling heads during milling processing, which requires operators to frequently replace the two milling heads, making it impossible to complete the processing of the current parts conveniently, which will further reduce production efficiency and cause delays in production tasks.
