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.
Cheater bars are appropriately named, especially when it comes to tightening tool holders. We see the common pipes that are often added to the end of wrenches to achieve more torque in customers’ shops all the time. And while these makeshift wrenches may make tightening or loosening holders easier, the damage they can cause is often overlooked.
When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.
Milling is a core operation in all kinds of manufacturing environments. Here are five different types of milling holders, each with their own strengths and weaknesses. We’re here to help you choose with a breakdown and tips for using each.
