SGS launches T-Carb mills at MACH 2014

The T-Carb end mills have been designed for aggressive, high speed machining using trochoidal and peel milling techniques. According to SGS, the additional flutes allow higher feed rates at reduced tool loads, ultimately preventing breakage and failure. The variable pitch geometry is said to allow the T-Carb to excel in aggressive roughing and finishing operations, resulting in faster cycle times and lower costs. Target applications include structural aerospace components, medical implants and devices, automotive mould tools and energy industry parts. Suitable workpiece materials range from common steels and stainless steels, through to high temperature alloys and titanium alloys. The geometry has been designed for workpiece materials up to 50 HRc. All T-Carb end mills feature six variable geometry flutes, which are ground in a variable index pattern. SGS says that this helps prevent the onset of chatter by disrupting the rhythmic striking of the cutting edges against the workpiece material. The tool is intended as a solution for end users embracing advanced CADCAM solutions, such as VoluMill, Delcam's Vortex, SurfCam, adaptive milling, and so on, states SGS. With more cutting edges than a Z-Carb or V-Carb, but not as many as the Multi-Carb, the T-Carb addresses a need from those preferring high feed milling at reduced radial widths of cut. Radial cut widths of 10% of diameter, or less, are possible, while axial cut depths can reach twice the diameter. Offered in a variety of length, neck and corner radius options, the T-Carb range is coated with Ti-NAMITE-X for high thermal barrier protection, says SGS. This proprietary coating is applied using the HiPIMS (High Power Impulse Magnetron Sputter) coating process for increased hardness and better resistance to abrasion wear. The coating is said to provide superior adhesion, which is critical in high performance applications that encounter extreme levels of mechanical stress. With a dense, more uniform coating structure, it is claimed that Ti-NAMITE-X permits improved performance at elevated temperatures. MACH 2014 - Birmingham NEC, 7-11 April
