Studer Adds Combitec Internal Cylindrical Grinding

Studer has announced that it has acquired Combitec as a subsidiary and can now offer the CT-450L, CT-960 and the S120 production grinding machines. The CT-450L CNC internal and universal cylindrical grinder for new users is the light version of the Combitec CT-450. With a range of applications, the CT-450L is suited to universal internal grinding applications, grinding collet chucks, and machining brittle and hard materials.

It features a linear spindle arrangement, use of either one or two spindles with speeds of 28000-60000rev/min, and cross-slide design. The CT-450 provides a range of expansion options, such as a C-axis for grinding all types of threads. The CT-960 internal, universal and radius grinder is a high-precision machine with a B-axis swivel to 91deg. A turret for up to four spindles allows efficient grinding of small to medium-sized workpieces, the company said.

In this particular design, the machine is suited for universal grinding tasks as well as grinding complex workpieces of brittle and hard materials like carbide, ceramics or sapphire. The stability and rigidity of the CT-960 also permit grinding die with radii, cones or path contours. The finished workpieces have polished surface quality. An optional CNC-controlled C-axis is available for grinding threads or non-circular shapes.

Sim-CT software helps with programming, set-up and simulation. The S120 production internal cylindrical grinding machine is a compact internal grinder for one or two independent grinding tasks. Optimally suited for an efficient machining of high-precision small parts, it is well established in large batch production. Typical applications are in the area of hydraulic components and increasingly in medical technology, for example, grinding ceramic balls for hip joints. Different handling systems can be integrated via the well-defined loading interface.

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.
