Mach 2010 To Feature Heidenhain's ITNC/TNC Systems

Heidenhain has announced it will attend Mach 2010, where it will display its ITNC/TNC range of systems. The high-end (up to 13 axes) ITNC 530 CNC analogue/digital system is suitable for producing accurate contours at high velocity - block-processing time is 0.5 milliseconds - and provides, for example, 3D-tool compensation. The ITNC 530 hardware option with two processors features the Windows XP operating system as a user interface, enabling the use of standard Windows applications.

Also on show will be the TNC 620, a versatile contouring control for multi-axis work. With workshop-orientated programmability using Heidenhain's conversational programming routines - or off-line programming - the TNC 620 is ideal for a range of applications, including either one-off or volume-production routines. For milling machines, the control offers free contour programming, cycles for complex contours and fast pre-setting with Heidenhain touch probes. For drilling and boring machines the system incorporates cycles for drilling, boring and spindle alignment as well as for linear and circular-point patterns.

Also designed for milling, drilling and boring routines, the TNC 320 is an entry-level analogue system ideal for retrofit applications. It has a TFT 15in (381mm) colour monitor that presents a clear overview of all relevant information for programming and operating, including program blocks, comments and error messages. More information is provided through graphic support during program entry, test run and actual machining. The selectable split-screen display shows the part-program blocks in one half of the screen and graphics or the status display in the other half.

During the course of the program, status displays offer information on tool position, current program, active cycles and co-ordinate transformations, for example. Heidenhain's Manualplus 620 CNC features application-orientated cycle programming to allow operators to rapidly create and edit programs on-screen. The system incorporates Smartturn technology, which incorporates form- and graphics-supported programming for complicated workpieces.

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.
