Side milling cutter for slot cutting

A side milling cutter for slot cutting comprising:

• a disc-shaped cutter;
• and
• a plurality of cartridges as cutting edges provided at a predefined interval in a circumferential direction along an outer circumference of the disc-shaped cutter;
• wherein the disc-shaped cutter cuts a predefined slot on a workpiece using the cartridges by circumferentially rotating, wherein
• the disc-shaped cutter internally includes a plurality of vibration damping structures in the circumferential direction on a disc surface of the disc-shaped cutter,
• each of the vibration damping structures includes viscoelastic bodies and a weight between the viscoelastic bodies,
• the weight is configured to be able to move in a direction to cancel a vibration mode of the disc-shaped cutter, the vibration mode being a mode in which an outer peripheral portion of the disc-shaped cutter vibrates undulating in an axis direction,
• the disc-shaped cutter has a disc-shaped cutter body,
• the plurality of cartridges are provided at the predefined interval in the circumferential direction along the outer circumference of the disc-shaped cutter body,
• inserts are attached to the plurality of cartridges,
• a shaft that is connected to the disc-shaped cutter body on a disc surface of the disc-shaped cutter body, the shaft rotating the disc-shaped cutter body, and
• the vibration damping structures are inserted into the disc-shaped cutter body in an area of the disc-shaped cutter body that is most distant from the shaft along a radially outward direction from the shaft,
• the disc-shaped cutter includes a disc-shaped cutter body,
• each of the vibration damping structures includes a weight;
• viscoelastic bodies for damping vibration of the cutter, disposed on both surfaces of the weight;
• a shim for adjusting pressure applied to one of the viscoelastic bodies, disposed on a surface of the one of the viscoelastic bodies;
• and a cover to hold the shim, the viscoelastic bodies, and the weight in the cutter body,
• each of the vibration damping structures is placed in a vibration damper hole formed on an outer or inner circumference side of the cutter body or in a cutting part of the cutter body,
• the weight has a groove on a side surface of the weight, and
• a ring-shaped viscoelastic body is placed in the groove.
