Sandvik Coromant Spotlight: How to Get the Best Machining Result with Milling Cutters and Tools

Everything these days seems to be moving at lightning speed, with many folks thinking the quicker the better. From procurement to delivery, we want it done, and we want it done yesterday. However, when it comes to machining applications, these speed and feed rates can make or break the reliability of your milling cutters and cause damage to your expensive machines. Some of the top things to consider in tough and demanding milling operations are heat, vibration, stability, functionality and adequate metal and chip removal rates, as well as good process security.

That’s why it’s critical that you understand the fundamentals of the cutting tools and equipment you use daily. Without the right milling cutters, cutter bodies and cutting tool technology, those high speeds can not only slow or stop your shop’s productivity, but also eat away at your profits.

Fortunately, our partnership with the industry’s most innovative manufacturer in tooling technology, Sandvik Coromant, has provided us with helpful advice and tips to help you get the most out of your machining operation. Need answers right now? Call us directly at 800-592-4516.

Let’s begin by explaining the 7 basic features of your milling cutters:

The Shank is the cylindrical shaped part of the tool that is used to hold and locate it in the tool holder. It can be round and held by friction or held in place with a set screw.

The Flute of a milling bit are the deep helical grooves running up the cutter.

The Tooth is the sharp blade along the edge of the flute that cuts the material. The flute, with the help of the rotation of the cutter itself, helps to expel the material up and away from the cutting surface.

The Helix Angle describes the flutes of a milling cutter. Usually flutes are helical to allow gradual entry into the workpiece. If flutes were straight, they would enter the workpiece at the same time, causing vibration and potential damage. Tighter helix angles with higher rake angles often provide a better finish.

The Milling Cutter Materials are often high-speed steel (HSS) or carbide. As a rule of thumb, softer materials can be machined with HSS and harder materials require carbide. But note that while HSS is less expensive than carbide, it does wear out faster, requiring more frequent changeouts.

Coatings are helpful in improving the hardness of a cutting edge and to reduce friction on materials that have low thermal conductivity, or are unable to control heat-build up on both the milling cutter and the work piece.

The Tool Life of your milling cutter is critical. If you have high production and heavy workloads, it’s critical to invest in the right tooling that can keep up with the volume of work. Choosing inexpensive or inadequate tooling costs time and money on wasted material, scrap, wasted tool spend and added wear and tear on your machines.

It’s not enough to just choose the right milling cutter for the job. You also need to understand how the milling cutter, the workpiece, and the machine all work together to get the best machining results.

Understanding the ABCs of Milling Cutters and Milling Operations

The following is from Sandvik Coromant:

A. The Milling Cutter
Milling isn’t a one-size-fits-all operation. Milling cutters cover a wide range of traditional operations that remove metal from workpieces, but milling cutters can be also be used in alternative ways to produce holes, threads, cavities or pocketing. The features to be milled require careful consideration as milling cutters come in many shapes, sizes, coatings and cutting surfaces. Does the milling depth require extended tooling or does the feature to be milled contain interruptions or inclusions? These are common questions you should ask yourself.

B. The Workpiece
Consider the workpiece and its machinability. The size part to be milled is limited by the machine’s capabilities and depth of cut required. Additionally, the material’s characteristics will determine the overall functionality. Characteristics like hardness, thickness, rigidity, chemical resistance, heat treatability and thermal stability all play a critical role, so special attention must be paid to choosing dedicated tooling and milling strategies.

C. The Machine
The milling method you choose will impact the type of machine you need. Typically, there are two configurations, vertical milling machines and horizontal milling machines. There are multitasking machines (MTM) that can handle a variety of operations including milling and lathing, but there are limitations. Choosing the right machine for the job will save you money on equipment repair and replacement, as well as saving on scrap costs.

The CoroTurn® Prime insert for all-directional turning is your solution for chip control in ductile materials. It’s ideal for use in finishing to semi-finishing operations in unstable set-ups or for machining slender components that require lower feed rates. The CoroTurn® Prime insert helps you achieve excellent chip evacuation and control in internal turning applications.

Parting and Grooving

Face grooving just got a whole lot more reliable. The CoroCut® QF has an innovative blade design that provides more material in the weakest cross-section for added strength and less mass in the front of the blade for enhanced stiffness.
