A kind of wave edge end milling cutter

Abstract

The invention discloses a wave-edge end mill comprising a mill body. An end edge front mill surface is arranged at the end portion of a mill head, auxiliary cutting edges are formed by intersection ofthe end edge front mill surface and an end edge rear mill surface, the edge shape of the auxiliary cutting edges is a sine curve, and peaks and valleys of the adjacent auxiliary cutting edges are staggered. The mill head is provided with a mill point part which is provided with a mill point edge, and a mill body chamfer is arranged at the end portion of the mill body and is 45 degrees. A specialmill clamp is used for machining the end edge rear mill surface into a wavy surface, so that the end edge rear mill surface and the end edge front mill surface intersect to form the wavy auxiliary cutting edges; the mill point strength is high, the speed of cutting off workpiece blank machining allowance is increased, and on the premise that the mill rigidity and strength are ensured, the cuttingprocess is stable, cutting is fast, vibration is low, chip discharging is smooth, and the metal removing rate is high; and the wave-edge end mill is more suitable for rough milling machining and especially suitable for milling and gas cutting of steel plates and other workpieces with rough surfaces, so that large-feeding cutting is achieved.

Description

technical field [0001] The invention relates to the technical field of end mills, in particular to a wave edge end mill. Background technique [0002] Milling refers to the use of rotating multi-blade tools to cut workpieces for high-efficiency processing. During work, the tool rotates (for the main movement), the workpiece moves (for the feed movement), the workpiece is fixed, and the rotating tool moves (to complete the main movement and feed movement at the same time). For movement), the machine tools used for milling include horizontal milling machines or vertical milling machines, and there are also large-scale gantry milling machines. These machine tools can be ordinary machine tools or CNC machine tools. Rotating milling cutters are used as cutting tools. It is carried out on a milling machine or a boring machine, suitable for processing planes, grooves, various forming surfaces (such as flower milling keys, gears and threads) and special surfaces of molds, etc. [0...

Problems solved by technology

In the milling process, in order to ensure the efficiency and quality of the workpiece milling, it is necessary to use the rough milling cutter to perform initial milling on the workpiece when milling the workpiece. The blade is easy to cause damage, and it is also easy to cause damage to the surface of the workpiece, which affects the processing speed of the workpiece and the service life of the milling cutter. In view of the above problems, the invention is specially designed to solve
