5 Things to Know About Helical’s High Feed End Mills

Helical Solutions‘ High Feed End Mills provide many opportunities for machinists, and feature a special end profile to increase machining efficiencies. A High Feed End Mill is a High Efficiency Milling (HEM) style tool with specialized end geometry that utilizes chip thinning, allowing for drastically increased feed rates in certain applications. While standard end mills have square, corner radius, or ball profiles, this Helical tool has a specialized, very specific design that takes advantage of chip thinning, resulting in a tool that can be pushed harder than a traditional end mill.

Below are 5 things that all machinists should know about this exciting Helical Solutions product offering.

1. They excel in applications with light axial depths of cut

A High Feed End Mill is designed to take a large radial depth of cut (65% to 100% of the cutter diameter) with a small axial depth of cut (2.5% to 5% diameter) depending on the application. This makes High Feed End Mills perfect for face milling, roughing, slotting, deep pocketing, and 3D milling. Where HEM toolpaths involve light radial depths of cut and heavy axial depths of cut, High Feed End Mills utilize high radial depths of cut and smaller axial depths of cut.

2. This tool reduces radial cutting forces

The end profile of a High Feed End Mill is designed to direct cutting forces upward along the axis of the tool and into the spindle. This reduces radial cutting forces which cause deflection, allowing for longer reach tools while reducing chatter and other issues that may otherwise lead to tool failure. The reduction of radial cutting forces makes this tool excellent for use in machines with lower horsepower, and in thin wall machining applications.

3. High Feed End Mills are rigid tools

The design and short length of cut of High Feed End Mills work in tandem with the end geometry to produce a tool with a strong core, further limiting deflection and allowing for tools with greater reach lengths.

4. They can reduce cycle times

In high RDOC, low ADOC applications, High Feed End Mills can be pushed significantly faster than traditional end mills, saving time and money over the life of the tool.

5. High Feed End Mills are well suited for hard materials

The rigidity and strength of High Feed End Mills make them excellent in challenging to machine materials. Helical’s High Feed End Mills come coated with Tplus coating, which offers high hardness and extended tool life in high temp alloys and ferrous materials up to 45Rc.

In summary, High Feed End Mill tools with specialized end geometry that utilizes chip thinning and light axial depths of cut to allow for significantly increased feed rates in face milling, slotting, roughing, deep pocket milling, and 3D milling applications. The end profile of a High Feed End Mill applies cutting forces back up into the spindle, reducing radial forces that lead to deflection in long reach applications. Combining this end geometry with a stubby length of cut results in a tool that is incredibly rigid and well suited for harder, difficult to machine materials.

John Force Racing – Featured Customer

John Force Racing has been dominating the motorsports world for over 30 years, winning 20 championships and hundreds of races in the National Hot Rod Association (NHRA) drag racing series. John Force Racing features both Funny Car and Top Fuel teams, and just recently in 2017 they won both the Funny Car and Top Fuel championships in the same season.

John Force Racing invested in Force American Made to develop and create parts and components that would help drive all the teams to success and safety. The 84,000 square foot shop is located in Brownsburg, Indiana (just outside of Indianapolis) and is the heartbeat of John Force Racing. Thousands of parts are forged by Force American Made and its team of employees every season giving the team a competitive edge that has led to the team’s on-track success.

The Force American Made team has relied on Helical Solutions tooling to get the best performance and quality out of their CNC mills for years. The Harvey Performance Company team was invited out to Indiana to take a tour of Force American Made and spend some time with Tom Warga, Lead Machinist, to talk with him about his experiences with Helical Solutions tooling, his first time trying Machining Advisor Pro, the success they have had using the new Helical tool libraries for Mastercam, and the value their distributor, Dolen Tool, brings to the shop. Check out the video interview below to see the inner-workings of Force American Made and how Helical Solutions tooling has contributed to the success of this motorsports dynasty.

Helical Solutions Engineers Featured in Strausak Video

Helical Solutions Director of Engineering Brian McKahan and Senior Manufacturing Engineer Forrest Thurston were featured in an April 2, 2017 Strausak video entitled “Stäubli robots at Strausak, to improve machine autonomy,” in which Helical’s use of this robot arm and its production benefits are discussed.

“We just picked up the Strausak machine in October specifically for our specialty form tools.” Thurston said in the video.

“I will have all of our carbide blanks in pallets, and once the job is set up, the robot will pick up the blank and it will put it in the machine in the holder. And when the tool is finished, it will place the finished tool in a different pallet and load the next part completely unattended.”

Due in large part to the Stäubli Robots and their ability to help maximize machine potential, production levels at Helical have grown tremendously since 2016.

“As anybody knows in the manufacturing industry, the floor space is critical,” McKahan said. “You want the smallest footprint you can get and the maximum value from the machine.”
