Description

High-performance precision forming groove round nose cutter

Technical Field

The utility model relates to the technical field of cutters, specifically be high performance precision shaping groove round nose cutter.

Background

Milling is a method of cutting a workpiece using a rotating multi-edge tool, and is a highly efficient machining method. During operation, the cutter rotates, the workpiece moves, the workpiece can also be fixed, but the rotating cutter also needs to move. The milling machine tool comprises a horizontal milling machine or a vertical milling machine and also comprises a large-scale planer type milling machine. These machines may be ordinary machines or numerically controlled machines. And a rotary milling cutter is used for cutting and processing the cutter. Milling is generally performed on a milling machine or a boring machine, and is suitable for processing planes, grooves, various forming surfaces, special surfaces of dies and the like. A milling cutter is a rotating tool for milling machining having one or more cutter teeth. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine. At present, in the design of some parts, arc transition edges with different sizes are designed at the root part of a cavity of the part, and the arc transition edges are generally machined and formed by a round nose milling cutter. The round nose milling cutter is a milling cutter with arc angles at two sides of a bottom edge, and the arc angle values at two ends of the bottom edge of the round nose milling cutter are usually smaller than the edge diameter value unlike a ball end milling cutter. The existing round nose milling cutter generally requires that the service life of the existing round nose milling cutter is as long as possible when the existing round nose milling cutter is used for processing parts. However, the existing round nose milling cutter is difficult to break through long-time processing in service life, the main characteristic is that the tool tip of the cutter is easy to wear, so that the precision and the size of a workpiece are deviated, and the round nose milling cutter needs to be replaced at the moment so as to ensure the processing precision of the part. The existing round nose milling cutter is not convenient for workers to replace, so that the operation difficulty of the workers is increased, the processing performance of the milling machine is influenced, the processing precision of parts cannot be guaranteed, the quality of the parts is poor, and the scientific production and processing requirements cannot be met.
