The additions have namely a square corner and a corner radius type in diameters 10 to 20mm, which have multiple internal through coolant holes. With the through coolant holes, very effective resistance to welding is achieved, especially during full slot trochoidal milling operations, Mitsubishi Materials says. Standard milling operations also gain in tool life and performance due to the spiral arrangement of the coolant holes, Mitsubishi adds.

According to MMC, the VQ solid carbide end mills have an (Al, Cr)N group Miracle Sigma-based coating that improves wear resistance. The surface of the coating has been given a smoothening treatment resulting in better machined surfaces, reduced cutting resistance and an increased chip discharge capacity. The extreme heat and oxidation resistance and lower coefficient of friction of the new coating allows for maximum performance and help prevent tool wear even under harsh cutting conditions when machining difficult to cut materials.

The use of irregular pitch flutes with varied helix angles also reduces vibration to enable more reliability and productivity. Moreover, the flutes have a wide chip pocket for improved chip disposal in this range. While previous technologies often resulted in diminished sharpness, the Zero-μ Surface achieves smoothness, sharpness and longer tool life. The VQ series employs a 2-stage gash to improve chip flow, help chip dispersion and reduce loads during full width slotting.

Mitsubishi Materials will be exhibiting at Metav 2018, in Hall 14, Booth B29.

Registration is open for Metav 2018. Exhibitors can registrate until 31 August 2017. (VDW)
