Reduce the cycle time and consistently meet dimensional tolerance specifications when machining a forged military component
A selection of cutting tools that includes a high-feed mill, a shoulder mill and an exchangeable-head drill.
Seeb Industrial Inc. is a diversified job shop that has been open for 38 years. Seeb focuses on CNC machining. “Our average run is about 250 pieces. Two hundred and fifty to 500 pieces are some of our larger runs, although we have done more,” said Vice President of Manufacturing Eric Nagy.
Seeb Industrial, Bedford Heights, Ohio, frequently does complicated one-part jobs on a CNC, he added, such as when a customer needs a replacement component for a machine for which parts are no longer being produced. “We will take a part, reverse-engineer it and get them back up and running.”
However, when the company got an order that indicated an annual total of 5,000 pieces, Seeb Industrial was concerned about the cycle time for the pieces, according to Nagy.
Seeb Industrial began by making prototypes and then determined which cutting tools of the 10 being applied consumed the most time. With that information, the shop consulted various suppliers. “We picked everybody’s brain from different tooling companies,” Nagy said.
Tungaloy America Inc., Arlington Heights, Illinois, was one of the cutting tool companies that Seeb Industrial contacted because the shop had worked with Jeff Fousek, a sales engineer for the toolmaker, on previous applications. Fousek proposed applying Tungaloy tools for several processes, and Seeb Industrial welcomed two of the suggested tools: the DoFeedMini indexable-insert high-feed mill and the Tung-Tri indexable shoulder mill.
Seeb Industrial started with a 1.25″-dia. high-feed mill but switched to a 7⁄8″ tool along with a shorter toolholder to enhance rigidity and help minimize chatter, Nagy said. “We got that tool running at 230 ipm.” Continue >
High-feed milling reduces cycle time and extends cutting tool life.
Cycle time plays a major role in productivity and often determines the profitability of any given job in today’s hypercompetitive machining market. Simply increasing the speed or revolutions per minute (RPM) may appear to decrease cycle time. However, the time it takes to change inserts hampers any reduction in cycle time, as the increase in speed or RPM shortens tool life, increasing cutting tool cost.
High-feed milling (HFM) is a solution to this problem. The tool works at elevated feed rates with modest speed or RPM, which reduces cycle time while extending tool life. These flexible and versatile tools can yield dramatically reduced cycle time and cost, long tool life and high-quality finished parts.

Using a robust 10-sided insert from Tungaloy, this oil-industry remanufacturer was able to reduce the number of inserts used in interrupted turning operations.
In the wake of the Deepwater Horizon oil rig disaster in 2010, the United States imposed many new regulations on deep-ocean drilling that necessitated the regular replacement of blowout preventers (BOPs), which are designed to prevent future spills. To reduce the cost, oil companies turn to remanufacturers for getting used BOPs back up to specification. One such remanufacturer is National Oilwell Varco (NOV), an international manufacturing company dedicated to the oil industry.
To bring a BOP back up to spec, the company welds it with Inconel, then machines the seams back down. To machine off the excess material, the company performs an interrupted turning operation, slowly lowering the cutting tool to the workpiece and cutting away the irregular Inconel seam.
Unfortunately, as the cutting tool engages the seam, it undergoes tremendous strains from constantly disengaging and reengaging with the seam. The most strenuous part of a machining operation for a cutting tool is the moment it makes contact with a part, which makes interrupted turning especially damaging for cutting tools. What this meant in practical terms for NOV was a lot of damaged inserts. READ MORE >>

Switching from a cutting tool insert that produced 24 parts per cutting edge to one that produces 40 parts per cutting edge saved a shop time and money.
Shops deal with different types of material, each with their own challenges. One material that can present some difficulties is 4140 steel. This material can have a tough crust or scale on the outside that is tough to machine and can wear down cutting tools quickly. However, special cutting tools can ease this process. For a shop in Mississippi, switching to a more efficient and economical tool from Tungaloy increased the number of parts it can produce per insert, saving time and money.
Helanbak got its start five years ago. The company’s owner, Kristian Agoglia, had come to the Columbia, Mississippi area to clean up in the aftermath of Hurricane Katrina. The equipment he was using, including trimmers and clippers, had blades that needed to be sharpened. He took them to a local company called Terry’s Bits, which was owned by Randall Terry. Mr. Terry and Mr. Agoglia became friends, and eventually decided to go into business together.
The core of Helanbak’s business is drill pipes, which are used to drill holes in the ground off of drilling rigs for water well service, geological surveys and rock mining. This accounts for about 70% of the company’s business. It also produces firearms and does other precision machining work. The ten-employee company has a range of equipment to complete this work, including a friction welder, three Mazak Quick Turns, a Mazak VTC, Haas VF-4 Superspeeds, two Okuma lathes and a Doosan-Daewoo HBL-06 lathe.
