Description
Technical Field
The invention relates to a V-shaped diamond shank milling cutter and a manufacturing method thereof, belonging to the technical field of wood processing tools.
Background
When a common handle milling cutter in the prior art drills a through hole, the bottom of a workpiece has the problem of easy edge explosion. The common shank milling cutter can only be used for milling edges or broaching grooves and can not be used for drilling through holes.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a V-shaped diamond shank milling cutter and a manufacturing method thereof.
The utility model provides a V type diamond handle milling cutter, includes the cutter body and welds first diamond blade, second diamond blade and the third diamond blade on the cutter body, first diamond blade, second diamond blade and third diamond blade mutually become 120 degrees and arrange, the front end of first diamond blade, second diamond blade and third diamond blade has first section V type blade and the second section V type blade that the contained angle is α that the contained angle is theta, first section V type blade hypotenuse length is good at second section V type blade hypotenuse length.
The included angle theta of the first section of V-shaped cutting edge is 100-120 degrees, the included angle α of the second section of V-shaped cutting edge is 30-45 degrees, and the length L of the inclined edge of the second section of V-shaped cutting edge is 1-3 mm.
A manufacturing method of a V-shaped diamond handle milling cutter comprises the following steps of welding diamond blades or polycrystalline diamond composite sheets on the front portion and the side portion of the handle milling cutter, arranging the diamond blades or polycrystalline diamond composite sheets on the front portion at 120 degrees, machining the front portion of the handle milling cutter by using a diamond grinding wheel grinding or electric spark machining method to form a first V-shaped cutting edge with an included angle theta and a second V-shaped cutting edge with an included angle α, wherein the included angle theta of the first V-shaped cutting edge is 100-120 degrees, the included angle α of the second V-shaped cutting edge is 30-45 degrees, and the length L of the inclined edge of the second V-shaped cutting edge is 1-3 mm.
The electric spark machining method is an electric spark forming machining method or an electric spark wire cutting machining method.
The invention has the advantages of effectively solving the problem that the bottom of the workpiece is easy to burst when the common shank milling cutter drills the through hole, effectively solving the problem that the bottom of the workpiece is cracked in a large area when the through hole is drilled, saving the machining cost and saving the consumption of the grinding wheel by the electric spark machining method.
