As the year comes to a close, the editors here at linearmotiontips.com (as, apparently, editors everywhere are prone to do) like to look back over the past year to see what our readers clicked on and read the most. As in years past, readers found our “back to basics” articles quite useful and so it’s […]

Linear motors find a home in CNC machines
For one manufacturer of CNC grinding machines, new high-performance linear motors replaced ball-screws and improved machine performance. It’s no secret that linear motors are highly effective motion devices. Linear motors can achieve high acceleration rates and long travel lengths with good thrust forces and extremely high positioning accuracies, while other drive mechanisms, such as belts, […]
Rediscovering ball splines for robust linear and rotary motion
Ball splines were once a staple for machine designers seeking an elegant way to integrate rotary and linear motion. Driven by pressures to speed their machines to market, many designers found it faster to implement prepackaged solutions in which rotary and linear motion shafts had already been integrated. By Charles Isaac • Thomson Industries Chris […]
New linear position detector series from Nidec
Nidec Machine Tool Corporation will launch the MPLS series, an inductive coupling principle-type linear position detector that determines a machine’s position and detects its feed digitally, on November 1st. Intended for compact machine tools, it uses a signal-detection method and integrates numbers of substrates to realize a simple structure that does not require scale wiring […]
A better control method for laser materials processing: Part 2 of 2
(This is the second article in a two-part series, the first of which can be found here.) Dr. Cliff Jolliffe Head of Automation Market Segment Physik Instrumente (PI) GmbH Modular controllers offer an easy and straightforward way to link a laser to multi-axis positioning systems. For instance, PI’s ACS Laser Control Module (LCM) introduces a […]
Linear and rotary motion components satisfy aerospace requirements
Linear guides, cam followers, and crossed-roller bearings can satisfy the demanding requirements for space-flight hardware. By IKO engineering staff | www.ikont.com As space activity shifts from governmental agencies to a growing industry driven by commercial entities and even startups, the types of spacecrafts and the missions they support are also expanding. This diversifying industry is […]
A better control method for laser materials processing: Part 1 of 2
New modular controllers offer flexible solutions for linking a laser to multi-axis positioning, making it easier for system integrators to design and build advanced systems for a new age of laser applications. Dr. Cliff Jolliffe Head of Automation Market Segment Physik Instrumente (PI) GmbH This is Part 1 of a 2-part series of articles on […]
Elevator stages feature 0.03 micron resolution
Optimal Engineering Systems, Inc. (OES) has released two new motorized elevator stages, the DAG20-120-01 and the DAG20-120-04. These high-resolution, compact, low-profile elevator stages feature high stability 120 x 120 mm tables and 20 mm of vertical travel. High precision ball bearing profile rails assure high parallelism and smooth motion throughout the raising and lowering of […]
igus offers custom toothed belt pulleys delivered in 48 hours
igus is expanding its 3D-print and online ordering offering to include custom format toothed belt pulleys. Toothed belt pulleys are a common component in many machines and are widely used in linear drives of printers, robots, and packaging machines. However, if an individual variant is required, developing a custom component can take days or even […]
