Description

Single-edge spiral milling cutter with replaceable cutting edge

Technical Field

The utility model relates to a spiral milling cutter technical field specifically is a single-blade spiral milling cutter of removable cutting edge.

Background

The milling cutter has a cylindrical shape and is provided with cutting blades at the circumference and bottom for performing a rotational movement to cut a cutting tool for machining a workpiece. The milling cutter is derived from a plane cutter. Only one side has the cutting edge on the planer tool, and when the planer tool moves back and forth, only one side has the cutting effect, so the time that the planer tool returns is totally wasted. The blade of the planing tool is narrow and therefore the efficiency of its machining is low. To overcome this drawback, the planing tool has been modified by mounting it on a shaft and rotating it rapidly to allow the workpiece to pass slowly from below, thus saving time, which is the original milling cutter, also known as a single-edge milling cutter.

A milling cutter is a rotating tool with one or more cutter teeth for milling. 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. A narrow blade zone is ground on the back blade surface to form a back angle, and the service life of the back blade is longer due to reasonable cutting angle. The tooth back of the sharp tooth milling cutter has 3 forms of straight line, curve and broken line. Straight tooth backs are commonly used in fine tooth finishing mills. The cutter teeth of the curved line tooth back and the broken line tooth back have good strength, can bear heavy cutting load and are commonly used for a coarse-tooth milling cutter.

Milling machine milling cutter when processing part changes the frequency very big, and milling cutter today mostly all is handle of a knife and cutting edge integrated into one piece, does not possess the split ability, and in the use, milling cutter's sword tooth often damages, but most milling cutter's sword tooth is unable change, and the sword tooth damages the back, just need change milling cutter, has caused huge wasting of resources.
