Alignment System

PI (Physik Instrumente) L.P. (Auburn, MA) offers the F206.S six-axis Hexapod alignment system that provides 6D motion with 33-nanometer resolution and alignment software for optics and photonics components. The system includes a parallel kinematics controller/driver featuring vectorized motion and arbitrary pivot point capability. Due to reduced moving mass (only one common platform for all 6 actuators), the system can respond and settle quickly.

Rail System

Thomson (Wood Dale, IL) has introduced the 500 Series Profile rails with an optional ball spacer carriage that reduces carriage running noise by up to 6 dB. The rails' design optimizes the surface interfaces between steel and plastic transition areas along the ball bearing circulation path. Standard end seals provide contaminant protection, with optional lowdrag end seals for low push-force requirements. Optional 440B stainless carriages and rails provide corrosion-resistant operation for medical, electronic assembly, semiconductor, and food and beverage applications.

Screw-Driven Linear Actuator

Bishop-Wisecarver Corp. (Pittsburg, CA) has introduced the HepcoMotion® PSD80 Profile screw-driven linear actuator with Herculane® wheel technology. Housed on an aluminum beam and fitted with a stainless steel sealing band, the actuator uses Herculane wheels mounted to an adjustable carriage. Single or multiple carriages on a unit are possible and can handle loads to 500N. A stainless steel lead screw provides actuation with pitch ranges of 4, 15, 25, and 70 mm. The lead screw is available in right- and left-handed threads. The actuator is supplied as a closed or open format, depending on the application being subject to ingress of dirt. Where two units are used in parallel, a slave axis without the driving screw can be specified for both closed and open units. It also is available in a corrosion-resistant version, as well as a double-acting version for applications requiring symmetrical movement from opposing carriages.

Vibration Monitor

SKF Group (San Diego, CA) has introduced the Multilog Online System DMx, a multi-featured vibration monitor for conventional and hazardous environments. It can be directly installed within a hazardous area, removing or reducing cabling, cabinets, and isolation barriers. It combines protection and condition monitoring in a single device, making it suitable for gas turbines, motors, pumps, and compressors. Features include four dynamic input channels for vibration, axial thrust, and dynamic pressure, with two channels for speed/phase measurement. Multiple LEDs provide local indications of module, channel, alarm status, and diagnostic data. The device can be connected to plant control and information networks by common protocols.

Brushless Motor Drive

DSC sensorless brushless motor drives from Koford Engineering (Winchester, OH) provide a programmable sensorless control for operation for 12- to 32-volt applications, with current up to 10 amps and speed of up to 96,000 rpm with a 2-pole motor. The 240-Watt drives use a digital signal controller, which can be programmed to match a specific motor and load to allow starting even high-inertia loads without excessive current draw. Closed-loop parameters can be customized.

Grippers

DPGplus sealed two-finger parallel grippers from Schunk (Morrisville, NC) are available in sizes 240 and 300. A pneumatic drive with oval pistons and multitooth guides ensure the user precise gripping for production machine and assembly applications. The grippers handle rough or dirty workpieces, and are suited for loading and unloading in harsh environments such as grinding machines, lathes, and milling machines. They also are suitable for use in powder coating systems or under water.
