Automation
The traditional approach has been to build very light, open-truss-designed gantry robots, he added. “You’ve got two X tracks in parallel, then the beam that goes across them is an open truss, like the truss you’d fi nd in a steel building,”
he said. “From that design standpoint, the way you get speed and performance is to keep taking weight out—you want as light a weight as possible. We think we’ve got a better alterna- tive for the increased demands for higher throughput in the packing area.”

A Must For All Dual Contact Applications
Güdel takes a different design ap- proach, he said. “We built our gantry mechanisms with welded box-beam construction and steel tube, not an aluminum truss. Our philosophy is to build the mechanism as stiff as possible, with a rack-and-pinion drive instead of the belt drive, and take that stiff mecha- nism and push a tremendous amount of power into it through the motors and the gearboxes—that’s how we get speed.”
Do Your Tool Holders Fit Your Spindle?
Non Deformed Tool Holder
Tool Holder fit is critical to all milling applications. Just because a toolholder is engaged with the spindle does not mean it is making full taper contact. When the toolholder is not properly seated with the spindle, the toolholder is susceptible to variable cutting force variations, misalignment, and harmonics.
Expanded Tool Holder
When a retention knob is installed into the toolholder the small end of the toolholder taper can become expanded.
The High Torque Retention Knob is the only retention knob designed to prevent toolholder expansion. With High Torque Retention Knobs you can expect:

When the taper is expanded it makes contact with the spindle before becoming fully engaged with the spindle. This creates a gap at the gage line and allows the toolholder to move during engagement. Toolholder expansion also effects the position of the cutting tool.
The deformation of the taper is in the elastic zone of the material and cannot be seen by the eye, but can be checked using a taper inspection gage.
“The robot guys want the best ratio of usable work envelope to footprint—the smallest dead space around the base of the robot, and the biggest work envelope.”
The new generation of Trackmotion adds improved performance and reli- ability. The frame is now a closed, gus- seted weldment that delivers increased stiffness with a smaller footprint. The enclosed frame design also prevents debris buildup in the center of the track. The track’s improved stiffness means less defl ection over the travel length, with repeatability of ±0.02 mm, the ability to operate at higher speeds and accelera- tion of up to 180 m/min, while requiring less fl oor space.
“The previous generation was kind of brute force, they would lay down two C channels and weld a bunch of cross beams, like railroad ties, across them,” Campbell said. “You still see people offering this, which is big and heavy. If
