Description

Technical Field

[0001] The utility model relates to the technical field of thread milling cutters, in particular to a thread milling cutter with a deburring function. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. Each tooth sequentially and intermittently removes the workpiece's stock. Milling cutters are primarily used on milling machines to machine planes, steps, grooves, formed surfaces, and cut-off workpieces. The milling cutter's blades are another important factor in optimizing milling results. Having more than one blade simultaneously cutting at any given time is an advantage, but having too many blades simultaneously cutting is a disadvantage. It's impossible for every cutting edge to cut simultaneously, and the power required is related to the number of cutting edges involved. The position of the milling cutter relative to the workpiece plays a significant role in determining chip formation, cutting edge load, and machining results.

[0003] An existing patent (publication number CN213998112U) discloses a thread milling cutter with a deburring function. This deburring cutter features a rational design, a circular file shaft with interlaced lines, and a connection between the cutter and a corresponding device. Rotation of the cutter drives the file shaft, which removes burrs. Two chip flutes are provided, located below the threaded cutting edge and the file shaft. These flutes facilitate the removal of waste chips during milling and burr removal. The cutter has a hexagonal fastening hole, which intersperses the fastening hole between the cutter and the corresponding device. The fastening hole provides greater stability during installation and prevents the cutter from falling off. A circular through-hole is located in the center of the fastening block, allowing the cutter to be hung for easy storage. The cutter body and the fastening block are connected by a threaded groove and a threaded column, making the threaded connection easy to disassemble and assemble.

[0004] However, there are some problems in the use of existing milling cutters: 1. The current milling cutter deburring assembly processes burrs through the provided grooves, but when the burrs do not need to be processed, the grooves affect the normal milling operation; 2. The existing deburring assembly will wear out after long-term use, but it cannot be replaced separately, and the entire milling cutter needs to be replaced, which increases the cost.
