Description

Technical Field

[0002] In the manufacturing process of indexable milling cutters, a crucial step is milling. The chip removal grooves on the cutter body, the insert positioning grooves, and the wedge grooves all need to be milled. Because the chip removal grooves are long, spiral grooves, the equipment needs to have simultaneous traverse and rotation functions, and it must have a large diameter (outer diameter > 200mm), a long length (effective cutting length > 600mm, total cutter length exceeding 1000mm), a finished product weight exceeding 150kg, and a high number of cutting edges (typically 20).

[0003] In the milling process, when ordinary equipment is used for processing, the workpiece rotates and moves laterally, while the tool moves up and down and forward and backward.

Large turning and milling composite machining centers are needed to complete the task. However, such equipment has a high unit price and high procurement cost, which is not suitable for the highly competitive market environment. Utility Model Content
