Planetary Gearbox

GAM (Mount Prospect, IL) offers the SPH inline planetary gearbox with helical gears for dynamic and cyclic applications, as well highspeed and continuous duty applications. It is available in six frame sizes with nominal torque ratings from 15 to 900 Nm. The face width of the gears provides more tooth contact and greater overall torque density. The gears are case-hardened, which imparts strength deeper into the gear. With several output configurations available, machine integration is simplified.

Clutches

U.S. Tsubaki Power Transmission, LLC (Wheeling, IL) announced Cam Clutch unidirectional/ mechanical clutches that lock the inner and outer races through the locking action of cams, transmitting torque in one direction of rotation while overrunning in the other. The cams are made of alloy steel, and the races are made of alloy steel with high surface hardness and core toughness. They are precision-ground to provide concentricity and surface finish for accurate cam rotation. For Free Info Visit http://info.hotims.com/55588-308

Electric Cylinder

SMAC (Carlsbad, CA) introduced the CBL50 electric cylinder designed to achieve peak force of 50N at 2 Amp current, and acceleration up to 40G. It features carriage-free design and built-in linear bearings. It is available with a vacuum and spring option for pick-and-place applications. With the optional IP65 and IP67 dustproof and waterproof feature, the cylinder is suited for applications such as food and beverage processing, packaging, and pharmaceutical industries. Stroke lengths of 10, 25, 50, and 100 mm will be available. The cylinder is offered with a choice of encoder resolutions, with 5-micron standard, and 1 and 0.1 micron optional. It is fully programmable in position, velocity, and force simultaneously. A patented “Soft-land” function ensures precise contact force. For Free Info Visit http://info.hotims.com/55588-305

Stages

Optimal Engineering Systems (Van Nuys, CA) released low-profile XYθ (theta) stages that move in an XY-plane and rotate around the center of the XY-plane. Available in 12 models in two precision grades, the stages have linear travels from ±2 by ±2 mm, up to ±30 by ±30 mm. The stages can rotate around the center of the XY plane up to ±6°. Four models have solid tables sized from 100 x 100 mm to 200 x 200 mm, and eight stages from 250 x 250 mm to 1500 x 1500 mm are hollow core (open frame) stages. Available in normal and precision grades, they have preloaded cross roller bearings, and typical normal repeated positioning accuracy is from ±1.75 μm to ±2.5 μm; typical precision repeated positioning accuracy is from ±0.7 μm to ±1.0 μm. Parallelism of the stages is as low as 30 μm, and the larger stages can handle dynamic loads to 600 kg. The stages can be ordered with linear encoders for closed loop operation, customized to meet specific requirements, and complete ready-to-run alignment systems.

Photo-Chemical Machining (PCM) of metals…faster & more cost effective than you’d think!

Photo-Chemical Machining (PCM) or photo-etching of metals is a mature process used to create very accurate metal components. This process emerged in the 1960s as an offshoot of the printed circuit board industry. PCM can produce highly complex parts with very fine details, quickly, accurately and economically. Photo etching is a cost effective alternative to stamping, punching, laser cutting, water jet cutting, or electrical discharge machining (EDM) of thin gauge precision parts.
