Renishaw To Demonstrate Products At Westec 2010

At Westec 2010, Renishaw will display products that increase machine-tool automation and process control, as well as a wireless device for assessing the performance of machines before metal cutting. The company will introduce new touch-probe systems that use its frequency-hopping spread spectrum (FHSS) probe signal radio-transmission technology to allow automated job set-up and in-process measurement on all sizes of CNC machine tools.

The ultra-compact RMP40 touch probe is suited to multi-axis and mill-turn applications, while its variant, the RLP40 touch probe, is designed for more hostile turning environments. Also on show at Westec will be the successor to Renishaw's QC10 ballbar system, which has been adopted worldwide for the assessment of machine-tool positioning and servo-control performance.

The QC20-W ballbar is a new design featuring a Renishaw-developed linear sensor and Bluetooth wireless technology, which also allows testing in three orthogonal planes through a single reference point. A single, simple hardware set-up means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy.

Renishaw's Resolute absolute optical-encoder system gives a resolution of just 1nm at 100m per second for linear encoder and angle-encoder applications, yet still offers excellent dirt immunity. Absolute position is acquired immediately at system switch-on, so the exact orientation of axis and motor commutation angle are known without the need for a reference (datum) return. Large set-up tolerances enable easy installation and reliability, while low jitter and SDE (sub-divisional error) meet the demands of high precision stages.

Visitors to Westec will also be able to see additions to the Toniic range of incremental optical linear and rotary encoders, including 1 and 2nm resolutions, a dual-output encoder interface and compatibility with Renishaw's Dual Signal Interface (DSi) for high accuracy angle encoding.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
