Renishaw Releases Lathe-Inspection Touch Probes

Renishaw's RLP40 and OLP40 lathe-inspection touch probes offer a choice of signal-transmission technologies, radio or optical. This makes part set-up and inspection on turning centres accurate, simple and reliable. Measuring just 40mm in diameter and 58.3mm long, the probes provide uni-directional repeatability of 1um and can be used to reduce set-up times, scrap and fixture costs, while improving process control.

Both designs are hardened and sealed to IPX8 to withstand the extreme environments typical of lathes and turning centres. A proven eyelid-protection system prevents entry of swarf and chips that could damage probe internals. The RLP40's frequency-hopping spread spectrum (FHSS) radio transmission pairs with the standard Renishaw Radio Machine Interface (RMI) and utilises the 2.4GHz frequency band.

The probe and its interface continually hop from one transmission channel to another, delivering unrivalled signal robustness and flexibility through frequency switching. Radio transmission allows continuous communication between the touch probe and the interface, even when line-of-sight is lost. The OLP40 uses modulated optical transmission for high resistance to light interference, and its 360-degree transmission systems allow the probe to operate in any orientation.

It also works with Renishaw's legacy transmission systems, while two touch-probes can be used on one turning centre when the OMI-2T interface unit is used. A wide range of shanks is available, including parallel and tapered designs, for maximum flexibility when mounting the probes in a lathe or turning-centre turret.

RMP40M and OMP40M transmission-only modules are also available to allow the use of Renishaw's LP2 range of touch probes and accessories in order to reach part features that would otherwise be inaccessible. Renishaw's range of tool-setting probes, inspection probes and probe software satisfies a range of machine-tool probing applications, from setting of tools and workpieces to process control and on-machine verification.

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.
