Mitsubishi Carbide ‘Solid-indexable’ end mills reduce inventory, shorten changeovers
The IMX series from Mitsubishi Carbide is said to combine solid carbide and indexable end mills to enable security and rigidity close to that of a solid-type end mill.
The taper and end clamping faces of the head and the holder are both solid carbide while the threaded part is steel. Other tools with a carbide head and carbide clamping section are usually constructed with a part carbide section brazed to a steel shank, creating an inherent weakness at the joint versus a solid carbide shank, the company said. The exchangeable nature of the series offers chances to reduce inventory and changeovers.
The mills target titanium alloys and heat-resistant alloys such as Inconel, along with stainless steels, carbon and alloy steels and hardened steels. Each head type has irregular helix flutes for vibration control and the four-flute corner radius type can incorporate coolant through-holes. The series incorporates the EP7020 “Smart Miracle” coated carbide grade for improved wear resistance, the company said.
Heads are supplied in five different geometries:
- Four-flute corner radius with through coolant – Ø10 - Ø25, with irregular helix for vibration control
- Four-flute corner radius – Ø10 - Ø25, with irregular helix for vibration control
- Six, 10 and 12 flute – Ø10 - Ø25 for finishing, with irregular helix for vibration control
- Four-flute and six-flute ball nose – Ø10 - Ø25, both with irregular helix for vibration control
