CNC machine tool efficiency is all about managing the components that must come together in proper alignment: the machine spindle, toolholder assembly and workspace.
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.
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.
There are three particularly sensitive areas of the tool holder assembly that can experience process-affecting wear and tear and cause a cycle to change.
This simple switch makes life much easier because it introduces more standardization to the shop floor, reduces the burden on operators, increases setup speed and dramatically reduces the chances of human error. All of which saves time and realizes return on investment – and each additional machine helps increase the rate of return.
Ansonia Manufacturing, the only machine shop in the town of Sonoma, California, discovered the EWN2-32ExER32 boring head and used it to complete a tricky hardware component job for a “live” glass art sculpture.
After researching presetters for eight years—including four trips to IMTS—CEO Ronda Peterson knew it was the time to invest in the next level of efficiency for her shop.
The first challenge to machinability – beyond simply working in titanium – for Colorado-based Cogitic Corporation was securing the cylinder in the universal machining center. It was also important to maintain access to the through-hole, which has an internal square key slot perpendicular to the stem hole.
Machining at higher speeds can save time and money, however, increasing the speed also means increasing the inherent risk in the situation. To maximize speed potential, a holistic approach that considers tool, holder, machine and operator is essential.
Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.
Accurate offsets and workpiece reference points are critical to effective setups and first-part accuracy. Taking a manual approach or attempting to verify these in the machine without the right measuring devices can be a delicate and time-consuming process.
