Shoulder milling is a basic milling application in which the tool creates both a flat surface and a shoulder surface. Shoulder milling cutters traditionally have a cutting edge angle of 90°. Having precise right angles is important to avoid offsets between individual milling passes. Both indexable and solid carbide tools are suitable for shoulder milling. Each tool has its own advantages.
The biggest feature of the shoulder milling cutter is that it has a 90° entering angle, which makes it have the following series of advantages: economy, flexibility and reliability.
Shoulder milling cutters can be used in many applications, including: plunge milling, ramping, circumferential interpolation, helical interpolation, drilling and face milling.
Repeat passes with shoulder and end mills. To minimize surface errors, such as scallops and transition edges between passes, a high-precision tool capable of producing a true 90º shoulder is absolutely necessary. If the shoulder depth is less than 75% of the cutting edge length, the quality of the vertical surface usually does not require additional finishing.
Shoulder milling generates two faces at the same time, which requires a combination of perimeter milling and face milling. Getting a true ninety-degree shoulder is one of the most important requirements. Shoulder milling can be performed using conventional shoulder milling cutters, as well as end mills, long edge milling cutters and side and face milling cutters. Since these options are numerous, operational requirements must be carefully considered in order to make the best choice.
The R390 shoulder milling cutter provides maximum economy and productivity without compromising process safety during demanding operations. The 3-flute inserts are designed with large rake and rake angles on the cutting edge to significantly reduce cutting forces, while the dual flank flute feature on the rear side of the insert provides strength and sharpness to the cutting edge. In addition, its variable pitch tool design significantly reduces harmonic vibrations that typically occur when using tools with equally spaced inserts.
Not only do shoulder mills give you true angles, but their durable construction and indexable inserts enable you to complete standard and custom applications.
