CARTRIDGE FOR A GROOVING TOOL HOLDER, CORRESPONDING GROOVING TOOL HOLDER, KIT AND ASSEMBLY THEREOF

摘要

The present invention proposes a cartridge for the grooving tool holder (60), the cartridge extends along the middle plane by being flanged between the left side and the right side, and the extension of the cartridge (20) along the intermediate thickness forms a boundary on the middle thickness plane by the peripheral surface of the cartridge (20). The peripheral surface of the cartridge (20) includes a clamping surface (28) for clamping by contact with the cutting insert (80) in the groove machining tool holders (60), and a front surface (24) and a rear surface (26) for fixing the cartridge by screwing the cartridge in the direction of screw connection (44) to the grooving tool holder (60). The cartridge (20) includes a coolant channel (30) extended in the direction (34) from the rear surface (26) to the front surface (24). The middle thickness plane of the cartridge (20) comprises both the direction of screw connection (44) and the extension direction (34) of the coolant channel (30). The invention also proposes the grooving tool holder (60) comprising an upper front surface (62) for fixing by screwing to the rear surface (60) of the proposed cartridge (20).
