Many factors may go into the decision to invest in a presetter such as tool budget, accuracy needs or delivery time. We’ve put together a reference guide.
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.
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.
The BIG DAISHOWA SPHINX drill series includes more than 2,000 different drills under 3 mm in diameter as standard. With a range of 0.05 to 3 mm diameters.
The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the precision and tolerances of micromachining processes.
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.
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.
