Emuge has expanded its line of FPC milling and drilling chucks to include Slim Line models that are designed to enhance five-axis machining productivity and versatility. Available in the 1/8" to 9/16" (2 to 14 mm) size range (FPC14), the slim design with tapered shape enables easier access to the work, especially in confined areas and for challenging angles, the company says.
The FPC is said to be the only chuck with a 1:16 worm gear, providing some three tons of traction force. The collet-cone assembly is designed to absorb virtually all vibration.
High transferable torque provides maximum process reliability, according to the company. Transferred torque on a tool shank diameter of 20 mm, for example, is 400 Nm. The 3×D tool length provides increased accuracy. Concentricity of ≤3 microns lengthens tool life and contributes to workpiece surface finish. The chuck is actuated with a mechanical drive using a hex wrench. The company says that the tool’s simple design enables tool changes in seconds.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
