In 1880, brothers and colleagues Jacques and Pierre Curie discovered that putting pressure on certain materials created electricity. Taken from the Greek word for “squeeze” (piezein), piezoelectricity was born. Commonly known as the “piezo effect,” it also occurs when an electrical field is applied and changes the dimensions of materials. More than 100 years later, PI Ceramic (a division of PI Physik Instrumente) is a leader in the field of piezo ceramic components, including its newest line of mini transducers.

A broad line of standard shaft collars, rigid shaft couplings and problem-solving mechanical components plus the ability to fabricate special parts are available from Stafford Manufacturing Corp.

Aerotech’s XC4 PWM digital drive is a single-axis motor drive designed for brushless DC, brush DC, voice coil and stepper motors at up to 340 VDC operating voltage and 30 A peak current. All versions are compatible with the Automation 3200 motion platform utilizing the HyperWire motion bus.

The new EC-i 52XL 200W brushless servomotor from maxon is a powerhouse. When space is limited but high torque and dynamics are required, the maxon EC-i 52XL motor is a suitable motor choice.

To greatly simplify the implementation of liquid cooling with torque motors and ease the mounting into direct-drive machine applications, ETEL announces that its TMB+ torque motor can now be ordered with a closed cooling jacket pre-built around it.

JW Winco Inc. offers an expanded range of rod end bearings, including GN 648.1/GN 648.2 steel zinc-plated, tapped type or with threaded stem and GN 648.5/GN 648.6 stainless steel, tapped type or with threaded stem.

Investments in conventional deep-hole drilling machines can be very expensive. SOMEX, a member of the Suhner Group, offers custom deep-hole drilling solutions capable of drilling up to 12mm diameters and as deep as 100 times the diameter. These modules can be integrated directly into transfer machines, special-purpose machines or conventional machines such turning machines. The potential for cost savings is substantial.
