Five-Face Millers For Large-Capacity Applications

The Hartford range of HSA five-face double-column vertical machining centres from Ward CNC is able to produce complex workpieces in a single setup. The machining centres feature W-axis (crossrail travel) and automatic head changing systems. Utilising either 4,000 or 5,000rev/min heads that have torque ratings of 750 and 500Nm respectively, three machines are available: HSA-4340-VW, -5340-VW and -6340-VW.

These have working table areas, respectively, of 4200mm, 5200mm and 6200mm (all by 2100mm) able to accommodate loads of 15,000, 16,000 and 17,000kg respectively. All three have a W-axis of 1100mm and ISO 50 spindle taper. The HAS-4340-VW has X-, Y- and Z-axis travels of 4050 x 3400 x 700mm (the Y- and Z-axis travel specifications are common to all three machines), a cutting feed rate of 1-8000mm/min and a rapid traverse in X of 12m/min.

Its rapid traverses in Y-, Z- and W-axis of 15,000, 12,000 and 3,000mm/min, respectively, are common to the HSA-5340-VW and HSA-6340-VW, which also have similar auto tool-changing capacities (32 as standard, 62 optional) and, likewise, spindle motors rated at 26/35kW. The HSA-5340-VW has an X-axis travel of 5050mm and an X-axis rapid traverse rate of 10m/min, plus a cutting feed of 1-6000mm/min. The HSA-6340-VW has an X-axis of 6050mm, a rapid traverse rate in X of 8000mm/min and a similar (1-6000mm/min) cutting feed rate.

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.
