KRQ Honing Tool For Mid-Volume Production Runs

The KRQ honing tool from Sunnen is said to combine the precision performance of custom tools with the low cost and quick-change flexibility needed for mid-volume production runs. Using a standard collet connection, the KRQ tool requires no indicating for parallel or conical run-out, speeding set-up and job changeover. This enables job shops to inventory a range of tool sizes for efficient processing of short production runs, while its ability to work with Sunnen's controlled-force honing technology enables shops to obtain the ultra-precise bore-size control typically requiring custom tools.

The KRQ tool is designed for optimum performance with Sunnen's SV-1000 series vertical honing systems, but it can also be used with ML series horizontal machines for reductions in set-up time. It is available in diameters of 5.0-19mm, in size increments of 0.10mm. The KRQ mandrel works with diamond and CBN superabrasives and utilises long-lived carbide shoes. When used with the controlled-force feature of Sunnen's multi-feed honing technology, it enables shops to cut cycle times by as much as 50 per cent while lengthening abrasive life and obtaining finer control of surface-finish parameters. Controlled-force honing maintains a steady, free-cutting, self-dressing condition for maximum metal removal in the short cycle time. For longer bores, the BLRQ tool offers the same advantages.

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.
