Prima Pulsed Nd:YAG Laser Drills Deeper Holes

Prima has announced the latest model of the Convergent Lasers CL-R pulsed Nd:YAG laser for drilling and cutting applications. 'This next-generation laser was designed to be an in-place replacement for the JK704 lasers used by Laserdyne Systems customers around the world,' according to Terry L VanderWert, president of Prima North America. 'It gives existing Laserdyne system users a replacement option for the JK704, while at the same time providing an upgrade opportunity for increasing the performance of their system,' he added.

Users of earlier model Laserdyne 780, 890 and 790 systems will be offered a turnkey retrofit package including complete on-site installation and startup assistance. The CL-R laser provides a wide range of process flexibility. It combines up to 50kW peak power with low divergence resonator optics to produce a high intensity laser spot for: drilling holes up to 75mm (3in) in length; drilling 3mm (0.12in) long holes at 10 holes/second on the fly; and cutting at 300mm (12in)/min or to 20mm (0.8in) in depth.

A long depth of focus enables deep holes to be drilled with reduced taper. Special pulse-shaping techniques can be used to improve the geometrical quality of holes drilled by single laser shots 'on the fly'. When retrofitted the CL-R will be compatible with existing beam delivery hardware and existing software programs, and will operate with existing chillers.

According to Laserdyne, retrofit applications have the potential for increased processing efficiency and lower operating cost, depending on the application, the system's condition and other factors. For example, longer life lamps are used in the CL-R laser, which have been reported by users of both lasers to lead to increased shot count before replacement. They also have a lower replacement cost. Laserdyne offers customer support via in-field installation, parts and service.

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.
