Moticont has released a new three-axis XYZ linear actuator, the XYZ-10. The X and Y axis of the actuator each has 0.97 in. (24.6 mm) of travel and the Z axis has a stroke of 0.500 in. (12.7 mm). The high-speed, high-acceleration, zero-cogging, brushless voice coil motors provide 6.3 lb (28.2 N) of force and […]
Gantry motion system for inspection, assembly, and 3D printing
Physik Instrumente’s (PI) new compact XY/XYZ gantry motion system provides overhead motion for industrial automation applications in assembly, pick-and-place, alignment, inspection, and custom 3D printer design. The A-351 compact gantry is designed and manufactured in the USA by PI’s air bearing & precision motion division in Hopkinton, MA. The A-351 gantry motion system is related […]
Part 2 – What is racking in gantry systems, and how can it be avoided?
In Part 1 of this post, we looked at various methods of driving the X axes in gantry systems and how the drive method can influence the gantry’s tendency to experience racking. Another factor that can cause racking in gantry systems is lack of mounting accuracy and parallelism between the two X axes. Racking is the common name […]
Stepper-, servo-based 400-mm hollow core motorized rotary stages from OES
OES (Optimal Engineering Systems, Inc.) has added two larger rotary stages to their AY110 Series of motorized rotary stages. The low-profile 400 mm AY110-400-01 (step motor driven) and AY110-400-02 (servo motor driven) rotary stages feature a 180 mm (7.087 in.) open aperture. The height of the stage is just 71 mm (2.795 in.). A precise […]
What is racking in gantry systems, and how can it be avoided? (Part 1)
Gantries differ from other types of multi-axis systems (such as Cartesian robots and XY tables) by using two base (X) axes in parallel, with a perpendicular (Y) axis connecting them. While this dual X-axis arrangement provides a wide, stable footprint and allows gantry systems to deliver high load capacity, long travel lengths, and good rigidity, […]
Review of linear actuation complemented by guide wheels
Linear bearings based on steel guide wheels often complement motor-based linear actuation in two challenging application types: Long-stroke linear-motion axes as those driven by belts, linear motors, or rack-and-pinion sets Linear systems in harsh environments subject to hot and humid conditions, abrasive materials, extreme loading, and corrosive chemicals. Recall that wheel-based linear guides are systems […]
New generation of linear motor stages from Yaskawa
The Drives & Motion Division of Yaskawa America, Inc. has added the Sigma Trac II series linear servo motor stages to the Sigma-7 servo family. Sigma Trac II combines a Yaskawa SGLF2 series linear motor with linear bearings, high-resolution absolute optical scale, cable management, and optional bellows to create a turnkey linear stage. Leveraging the […]
What types of motion can you create with multi-axis linear systems?
For many tasks, multi-axis linear systems — Cartesian robots, X-Y tables, and gantry systems — travel in straight lines to achieve quick point-to-point movements. But some applications, such as dispensing and cutting, require the system to follow a circular path or a complex shape that can’t be created by simple lines and arcs. Fortunately, modern […]
New compact, high-resolution two-axis gimbal mount from OES
The new, compact AU100-ER two-axis gimbal mount from OES (Optimal Engineering Systems, Inc.) features a full 360 degree continuous rotation of each axis. This compact two-axis gimbal mount handles loads to 10 kg (22 lb) and has a clearance of 300 x 300 mm, (11.8 x 11.8 in.) about the roll axis of the stage. […]
