Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.
Runout is one of the sneakier issues machinists and tool managers must deal with. It’s almost impossible to recognize in-process and difficult to diagnose after the fact. We identify potential sources.
Understanding and controlling runout is crucial for any machine shop looking to maintain competitive advantages in today's precision-driven manufacturing environment.
Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.
Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.
Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
After years of close observation and collaboration with manufacturing companies of all sizes, BIG DAISHOWA Seiki engineers have learned how the choice of tool holders affects production costs on the shop floor.
