Curtis Launches Dual-Spindle Grinding Machine

Curtis Machine Tools has introduced a dual-spindle grinding machine, the Vector Twin. The model retains all the key features of the Vector, such as small footprint for more production per square metre of floor space and a fast and versatile integral loading system.

Configured for grinding a Diesel Fuel Injection Nozzle component, the Vector Twin exhibited on the Tecno Team stand at Grindtec will be fitted with a standard Curtis three-axis Cartesian automatic loading/unloading system and two-draw pallet system. The Vector Twin is designed for very high-volume production and allows two or more processes to be performed concurrently.

For example: loading while grinding or performing a post-machining process such as de-burring or gauging, unloading then re-loading while grinding. Within the overall cycle time for each workpiece, the machine will typically achieve a non-grinding time of 2sec. The Vector Twin's spindles are mounted in a rotating drum and are separated by a dividing plate that forms a seal between the clean and grinding areas.

At the end of each grinding cycle the drum rotates through 180deg to introduce the next workpiece to the grinding wheel. A magnetic breakaway joint included on the Vector Twin protects the vertical gripper slide of the loader in the event of a loading error. As with the standard Vector, components can be feed in various ways, such as robot, vibratory bowl feeder, hopper or pallet.

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.
