Over the last few years, Union Tool says, the demand for extended life of molds and dies has led to the supply of new technologies that meets the machining needs of cutting high hardness and/or abrasive alloys with accuracy, extended tool life and cost-efficient programs.
Over a year ago Union Tool launched the HGB/HGLB ball nose series, which is said to have met these goals. More recently, the company release a four-flute, long neck radius end mill series, HGLRS 4000, for a corner radius option.
Like HGB/HGLB, Union Tool’s enhanced carbide material, HMG coating and altered geometries enable HGLRS 4000 to meet the challenges of milling alloys over 60 HRC. The carbide material and coating work to reduce tool wear along with new rake angle geometries that hold up to the heat and necessary cutting force.
According to Union Tool, case studies have found when using the HGLRS series for finishing, surface roughness (Ra) became smoother, and wall accuracy (Rz) in vertical direction improved
The initial launch offers 72 models in diameters ranging from Φ1 to φ6, with various corner radius and length options.
