CUTTING DEBRIS CRUSHING DEVICE, CUTTING DEBRIS CRUSHING BLADE, AND CUTTING DEBRIS CRUSHING DATA COLLECTION METHOD IN SAID CUTTING DEBRIS CRUSHING DEVICE

摘要

It is possible to efficiently crush long cutting debris or tangled cutting debris by making it difficult for cutting scraps to escape from a crushing blade. A cutting debris crushing device (10) is provided with: multiple cutting debris crushing blades (30) having base parts (31) securely attached at an interval to a rotation drive shaft (11) disposed within a casing (20) that opens to the top surface, and at least one rotating blade (33) which extends from the base parts (31) in the outer circumferential direction; multiple first secure blades (41a, 41b) which come into contact with the side surfaces of the cutting debris crushing blades (30) and which crush cutting debris in cooperation with the blade part on the side surface of the rotating blade (33) of the cutting debris crushing blades (30); and multiple second secure blades (43a, 43b) for crushing cutting debris in cooperation with the blade part on the outer circumference of the rotating blade (33) of the cutting debris crushing blades (30). The rotating blade (33) of the cutting debris crushing blades (30) is provided with raking blades (34a, 34b) having a rake angle relative to the rotation circumferential direction, and straight blades (36a, 36b) extending in the outer circumferential direction from the rake blades (34a, 34b).
