Broaching Unit Features Lightweight, Rigid Design
Eastec 2019: The redesigned Benz LinA 4.0 broaching unit is lighter and more rigid than its previous version.
The redesigned Benz LinA 4.0 broaching unit is lighter and more rigid than its previous version. It is said to be capable of as many as 1,500 strokes per minute. Fine-tunable and equipped with a standard gear ratio of 2-to-1, this unit minimizes or eliminates vibration, improving the life of the cutter, according to the company. Internal coolant can be provided through the plunger, while improved materials are said to protect against leaks.
Also available on the unit is the Benz i.com application to gather performance data.
A reader recently asked about speed, feed rate and depth of cut when using small tools in steel.
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.
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.
