Shrink-Fit Machine Accommodates ER Collets

Haimer USA’s shrink-fit machine, Power Clamp Sprint i4.0, is being marketed as an entry point into the Industrial Internet of Things (IIoT). The machine is engineered to provide both ergonomic operation and integrated cooling for all types of cutting tools (for example, solid carbide and high speed steel, or HSS) in a short time. A special holding fixture enables use of the machine with ER collets, expanding the Sprint i4.0’s use to Swiss-type and live tooling.
The system features software said to simplify usability, an intelligent cooling system with temperature control, and a durable 7" touchscreen display. Users can also customize the Sprint i4.0 with a laser scanner to read and set shrinking parameters automatically. These capabilities are said to eliminate variation between tool changes, resulting in repeatable uniformity in tooling setup and therefore consistent quality results.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
A reader recently asked about speed, feed rate and depth of cut when using small tools in steel.
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.
