Slides

NB Corporation of America (Hanover Park, IL) released TOPBALL® slide products that self-align. The floating wiper seal makes unrestricted self-alignment possible. A floating load plate adjusts clearance, and tolerances are achieved by grinding the raceways and load plates. Applications include automation equipment, machinery, and optical and measuring instruments. They also are suited for new designs and are interchangeable for retrofitting. The slide products are available as total systems or as individual components such as slide bushings, housings, slide shafts, and supports in metric or inch.

Clutch-Brake

Nexen Group (Vadnais Heights, MN) introduced the Flange Mounted Clutch-Brake Enclosed (FMCBE) for any environment where cleanliness is a primary concern. A single, double-acting piston prevents simultaneous clutch and brake engagement. It features a nickel-plated finish to resist corrosion, and stainless steel, hex-head bolts with no exposed threads or sockets. All machined mating surfaces are sealed with O-rings to prevent ingress of fluids. The clutch-brake has no indentations, allowing easy cleaning and eliminating areas of possible build-up and contamination.

Variable Frequency Drive

American Control Electronics (South Beloit, IL) introduced the ACF Series of open chassis microprocessor-based variable frequency drives that offers the simplicity of a DC drive. ACF700 drives are designed for setup without any programming. The drives are equipped with user-adjustable trim pots to set Max/Min Speeds, Slip Comp, Boost, Torque Limit, Accel, and Decel/Injection Braking parameters. The 115V/230V single-phase input can provide single- or three-phase outputs of 115V or 230V for sub-fractional HP motors and gearmotors. An onboard microprocessor allows custom programming for a variety of OEM applications. Other features include 1/60 to 1 HP, carrier frequency of 1.6 or 16 kHz, adjustable base frequency, DC injection braking, and protection against overheating as a result of frequent overload.

Servomotors

Siemens Industry (Elk Grove Village, IL) offers Simotics 1FK7 Generation II servomotors with seven shaft heights, quick-connect power connectors, and 20- and 24-bit field-replaceable encoders. The series offers three inertia versions — standard, high-dynamic for rapid acceleration jobs, and high-inertia for maximum smooth running. The motors are designed for operation without external cooling; heat is dissipated through the motor surface. The encoders are mechanically and thermally decoupled from the motor, making them more resistant to vibration conditions on the machine. The servomotors provide cross-profiling for mounting, Drive-Cliq interface for field commissioning and unit recognition with the Siemens Sinamics S120 drive family, plain shaft or keyway design, and three IP ratings.

Linear Actuator

Midwest Motion Products (Howard Lake, MN) offers the Model MMP LA3-12V-5-A-SP- 100 linear actuator that utilizes an all-steel drive pinion while maintaining a 5:1 reduction ratio that allows the unit to maintain a 2"- per-second stroke speed. The stroke length for the design is 4" overall, but the same design is available with 2, 6, 8, 10, and 12" stroke lengths. The actuator features 8-mm-diameter clevis mounts on both ends, and built-in limit switches for both (full extend and full retract) ends of travel. The operating temperature rating range is from –26 °C to +65 °C. An acme screw drive allows for 517 pounds of static load.

Press Brake

The GOFORM portable electric press brake from Cincinnati Incorporated (Harrison, OH), is designed for parts up to 1/4" thick and less than 50 pounds. It features a large touchscreen control, PC-based 3D graphics, and bend simulation. The unit guides the operator though setup and part handling sequences. Additional features include 0.0002" ram repeatability, Dynamic Thickness Compensation (DTC), 6-axis backgage, quick-clamp system, and 22" gage depth.

Encoder Modules

Heidenhain (Schaumburg, IL) launched MRP 2000, 5000, and 8000 encoder modules that contain bearing sets not conventionally available that can be integrated with various encoder types. These angle encoder modules merge requirements for precision rotary axes used in metrology, calibration devices, automation technology, micro machining, and the semiconductor industry. The modules offer low starting torque and a constant continuous torque. Bearing loads up to 300 Newtons are possible while still maintaining the system accuracy. Incremental or absolute encoders can be used as required, with resolutions up to 29 bits.

Automated Measurement Cell

Hexagon Manufacturing Intelligence (North Kingstown, RI) announced the 360 Flexible Measurement Cell, an automated measurement work cell suited for automotive and aerospace structure applications including powertrain and closure panel fabrication. The cell is built on commercial-off-the-shelf (COTS) work cell systems integrated with the company’s measurement solutions. The cell combines external devices, products, processes, and systems in a COTS format to enable them to be easily customized. The cell is scalable, portable, and modular, and is offered in three configurations: in-line, near-line, or off-line. Solutions are scalable as required by specific part size and measurement tasks.
