Abstract
A face milling cutter capable of changing position at 45 degrees relates to a face milling cutter and aims at resolving the problems that an existing 45-degree face milling cutter is low in blade utilization rate, and a blade groove is extremely easy to be abraded to lead to discarding treatment of a cutter body. The face milling cutter comprises a cutter body, eight cutter clamps and eight blades, eight cutter clamp grooves are evenly distributed on the cutter body along the circumferential direction, and each cutter clamp is detachably connected with a corresponding cutter clamp groove. The head of each cutter clamp is provided with a cutter groove, each blade is in the shape of a regular octagon, and the shape of the cutter heads of the cutter clamps are identical with the appearance of the octagons of the blades. An upper end face of the tail part of each cutter clamp is provided with a boss, the bosses are positioned on outer end faces of the cutter clamp grooves for axially positioning the cutter clamps, each edge of each regular-octagon-shaped blade is provided with a cutting edge, and each blade is detachably arranged in the blade grooves. The face milling cutter capable of changing position at 45 degrees is used for milling faces of vanes of turbines.
Description
Technical field
The utility model relates to a kind of face milling cutters.
Background technology
Present 45 ° of face milling cutters adopt square cutter blade, and blade is directly installed on the cutter hub, the weak point of this milling cutter is: owing to be square cutter blade, blade has four cutting edges, can only transposition use for four times, the blade utilization rate is low, and the insert groove of face milling cutters very easily weares and teares when using, when insert groove heavy wear, whole cutter hub is just scrapped processing.
The utility model content
The purpose of this utility model provides a kind of indexable 45 ° of face milling cutters, and is low with the blade utilization rate that solves present 45 ° of face milling cutters, and insert groove very easily weares and teares when using and causes cutter hub to scrap the problem of processing.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described face milling cutters comprise cutter hub, eight cutter holders and eight blades, cutter hub is uniformly distributed along the circumference and is provided with eight cutter holder grooves, each cutter holder and corresponding cutter holder groove removably connect, the head of cutter holder is provided with insert groove, each blade is an octagon, the shape of the cutter head of cutter holder is consistent with the octagon profile of blade, the afterbody upper surface of each cutter holder is provided with boss, boss is positioned on the cutter holder groove outer face, be used for the axial location cutter holder, every limit of each octagon blade is provided with cutting edge, and each blade detachably is contained in the insert groove.
The utlity model has following beneficial effect: the utility model has adopted the octagon blade, the indexable use of each blade eight times, improved the blade utilization rate greatly, owing to adopt holder structure, when insert groove heavy wear, only the cutter holder that need more renew gets final product, and has avoided the integral body of cutter hub to scrap, and has saved a large amount of these cutter costs of use.
