Technical Field

The utility model relates to a machining equipment technical field specifically is a powerful cutting bulb sword.

Background

The ball-end cutter is a cutter with a cutting edge similar to a ball head and assembled on a milling machine for milling various curved surfaces and arc grooves; in recent years, with the development of science and technology, the requirement of the machining precision of the machine manufacturing industry is higher and higher, and the drill bit is used as a common machining tool, the structure of the drill bit not only determines the strength and the service life of the drill bit, but also determines the error size and the precision of drilling a workpiece hole, but in the rough machining process, the existing ball head cutter cannot adapt to high-feed machining, and in the rough machining process, the existing ball head cutter is used, so that the efficiency is lower.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes the above circumstances is not enough, provides a powerful cutting ball head sword, its technical scheme as follows.

The utility model provides a powerful cutting ball head sword, includes hilt portion and cutting edge portion, hilt portion and cutting edge portion integrated into one piece are equipped with a plurality of cutting edges on the cutting edge portion, and the back knife face of cutting edge is located one side cutting of cutting end and has first helicoid, and the back knife face of first helicoid is located one side cutting of cutting end and has the second helicoid, and the front knife face of cutting edge is located one side shaping of cutting end and has the rib.

Further, the forming angle of the reinforcing part is 2 degrees.

Furthermore, a chip groove is arranged on the front knife surface of the knife edge.

Optionally, a transition surface is arranged on the rear knife surface of the knife edge, and the transition surface is arc-shaped.

Optionally, a blocking block is formed on the handle portion and located on one side of the blade portion.

Optionally, the end of the tool shank is provided with a chamfer.

Optionally, a plurality of adjusting grooves are arranged on the tool shank portion, and the adjusting grooves are located on the other side of the blocking block.

Compared with the prior art, the beneficial effects of the utility model reside in that:

can strengthen the intensity of bulb sword through the cutting edge, can cut thermal treatment material through being equipped with the rib, to the high processing of feeding of stiffened material, promote production efficiency, through the cooperation of cutting edge, first helicoid, second helicoid and rib, can make the precision of drilling better.
