Extruded-Section Company Buys RSA Deburring System

A manufacturer of extruded sections has invested in measuring systems from Ascona and deburring systems from RSA. The main target was an improved control of the dimensional accuracy of extrusions during regular extrusion-moulding process. The Ascona measuring system enables measurement directly in production at the press, since the system is encased for protection against vibration and dirt. Most complex shapes of extrusions can be measured within seconds, with an accuracy of +/-10um.

The immediate correction of the extrusion-moulding process secures the production process and reduces the risk of pieces outside of determined tolerance. The RSA Rasamat system was developed for the deburring of aluminium extrusions and, in this way, superseded band processing. The deburring system offers the additional automation of the preparation of specimen and works with a surface brush that is equipped with segmented wire or nylon trimming, with double rotary motion.

The segmented trimming prevents the wire tips from bending and, as a result, all areas of the extrusion are properly deburred. The brush is guided by a planetary gear and, independent of the geometry of the extrusion, all edges are properly rounded off, free from secondary burr. No manual re-working is necessary. Depending on their size, the specimens can be manually or automatically fed to the deburring system. In combination with the Ascona system, it is possible to determine precise correction values for the extrusion-moulding process - independent of the degree of skill of the operator.

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.
