GEOID Software Reduces Tool Costs

Blohm Jung has announced that at the Schleifring Grinding Symposium 2009, it will present, under the expression GEOID, a new development for compensation of contour faults in dressing tools. The example shows the quick manufacture of a blanking punch on the Vario D. GEOID was developed in conjunction with the Georg Simon Ohm University in Nuremberg.

The software for compensation of uneven wear in dressing tools is a further development of the automatic diamond adjustment by Blohm Jung and is used in conjunction with the CNC PA37K profile dressing device and the table version PA130TM. Topography of the cutting edge of the dressing tool can be determined with accuracy using GEOID. The correction values calculated are fed directly into the dressing program and create a perfect contour on the grinding wheel.

The result is an increased service life for the dressing tool, reduced costs of tools and improved contour accuracy. For profile grinding, different dressing systems are available for the Vario range of profile grinders by Blohm Jung. According to requirements, profiled crushing units, fixed-profile diamonds or swivelling diamond wheels are mounted on the grinding table. The company said a highlight of the range is the CNC PA37K head-dressing unit.

The function 'CD Abrichten' (continuous dressing), or parallel dressing cuts machining times by up to 50 per cent. Blohm Jung will also show how the GEOID correction software determines the actual contour of the diamond via a measuring probe and then corrects the dressing program accordingly. Therefore GEOID compensates for the wear in individual diamonds and diamond wheels, increases the usability of the dressing tools, and reduces the costs of tools.

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.
