Turning Tool Suits Semi-Finish to Medium Machining

Taegutec has launched the PC Positive Chipbreaker, designed for turning operations under a variety of cutting conditions, including the machining of steels, inconel, aluminium and cast iron. Part of the Taegutec T-Turn range, the new insert designation has been developed for the steady and continuous control of swarf to improve tool life and machining stability. The single-sided PC Chipbreaker insert is suitable for semi-finish to medium machining and can be applied to a variety of applications and materials.

The geometry of the new insert incorporates a slightly waved cutting edge, a dimple design for low cutting forces and a wide chip groove for smooth and consistent machining. These attributes enable the new grade to deliver improved tool-life performance when compared to competitor products for the machining range from 0.5 to 3mm depth of cut. Operating at feed rates from 0.1 to 0.3mm/rev when machining at speeds in excess of 200m/min, the PC Chipbreaker comfortably machines carbon steels, stainless steels, high tensile cast iron, aluminium, inconel and hardened steels.

Suitable for automotive, aerospace and general engineering applications, the PC Chipbreaker is available as a PVD, CVD or Cermet-coated grade for the demands of the various materials it is capable of machining. For the diverse turning requirements of the marketplace, Taegutec is introducing three options - the five, seven or 11 degree positive inserts. The widely used seven degree insert is available in seven different forms for the wide variety of tool holders currently in use in the marketplace. At present the five degree insert is available in the VBMT designation whilst the 11 degree inserts are available in CPMT and TPMT formats.

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.
