Carbide Blades Cut Flanges and Rings Efficiently

The PTZ Ring Cutter, available from Saws UK, is a parting-off unit said to deliver around 60 per cent savings in material and cut up to four times faster than conventional methods. Using the latest chip breaking carbide blades, originally designed for high speed billet cut off machines, kerf wastage is said to be reduced from 20 to 3mm. Available on a 12-week lead time from the machine manufacturer, the sawing unit with pick-and-place clamping system can be retrofitted to an existing vertical lathe or supplied as a turnkey package.

The saw head rotates simultaneously with the lathe spindle to give a good surface finish whilst the workpiece is held securely by the patented clamping system. Examples of cutting times are available to assist companies with costing: for example, ring from steel 18Cr Ni Mo 7-6, 1,060mm diameter with 65mm wall resulted in a parting-off time of 20 minutes.

Optional extras can be supplied with the kit such as drill, boring and tapping heads that can be used prior to parting off together with a deburring station to finish off the rings as they are removed by a pick and place unit. Currently two machines are being installed in Nuremberg - one with 1,000mm capacity and the other with 2,000mm capacity to produce a predicted one million rings per annum.

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.
