At Millat Industries we love to “Hog Out” on some 625 Inconel!

February 7, 2025

Hog Out machining is a rough cutting technique used to rapidly remove large volumes of material, particularly during the initial stages of machining. This method is essential when working with tough alloys like Inconel 625, a high-performance nickel-based superalloy known for its strength, oxidation resistance, and ability to withstand extreme temperatures. Inconel 625, commonly used in industries like aerospace and power generation, presents machining challenges due to its resistance to cutting tools, work hardening tendencies, and abrasiveness. Companies like Millat Industries, known for their expertise in high-performance machining, leverage these techniques to optimize material removal and extend tool life while delivering high-quality components.

To successfully machine Inconel 625, high-performance tooling, such as carbide or ceramic inserts, is crucial due to the alloy’s toughness and heat resistance. Millat Industries, with its advanced manufacturing capabilities, understands the importance of balancing cutting speed, feed rate, and depth of cut to prevent excessive heat buildup, which could lead to work hardening and tool damage. The company uses efficient chip removal methods and high-pressure cooling systems to manage heat and prolong tool life. By combining fast feed rates with moderate cutting speeds, Millat Industries ensures that material is removed efficiently without compromising quality.

Hog Out machining of Inconel 625 offers rapid material removal and cost-effective roughing, but it also presents challenges like tool wear and heat management. Companies like Millat Industries, with their commitment to precision and innovation, overcome these challenges through the careful selection of tooling and machining strategies. By employing the right cutting parameters, tool materials, and cooling techniques, Millat Industries consistently delivers high-performance components at competitive pricing for industries where quality and durability are paramount.

Hog Out machining can be a good solution if your product currently comes from a casting and you are experiencing quality, delivery, or cost issues with your current supplier. Millat Industries recently worked with an Aerospace OEM to change over two cast products to bar stock Hog Outs. The customer was facing very high scrap rates at weld due to latent material defects (inherent in the cast material). The customer’s primary goal was to reduce their scrap rate and optimize lead time, both of which were readily achieved with the bar stock Hog Outs.

With a large investment in 5-Axis Machining Centers and high material removal rates, Millat Industries is ready to support your complex Hog Out projects.

Let Millat Industries show you the way to be a HOG!
