NEW: Probe Z-Nano for Tool Setting and Broken Tool Detection

Compact Tool Setting Probe, Precise and Economic – Blum-Novotest is introducing their new probe Z-Nano

Blum-Novotest, leading suppliers of innovative, high-quality measuring and testing technology are presenting their new probe Z-Nano. This extremely compact tool measuring system is used in CNC machining centres for automatic tool length measurement and breakage detection as well as for temperature compensation in one machine axis. The new Z-Nano is the further development of an approved system known under the identical name and available already for many years.

Mr. Weiland, Sales Engineer at Blum-Novotest, explains: “We are sure that we will have the same success with this new Z-Nano as we had with the previous version which is used and approved every day all over the world. With the further development of this system we could realize some improvements. One of these improvements is an exchangeable measuring surface which allows worn measuring surfaces to be replaced a new one. Another improvement is the additional adjustment possibility by a spheric disk which enables easy adjustment on the machine table.”

The principle of linear guide was brought to perfection by the engineers of Blum-Novotest. Instead of the previously used sliding guide the new Z-Nano is working with a ball guideway by which the measuring force could be reduced once more. The advantage is that now even smaller tools starting from diameter 0.1mm – depending on tool geometry and material – can be measured. Furthermore the probe in its standard version is impressive by its high repeatability of 0.5 µm 2σ. For special applications it is also available in ‚High Precision’ design with a guaranteed repeatability of 0.2 µm 2σ.

As all other tactile systems by Blum the Z-Nano is complying with protection class IP68 and is working with an optoelectronic measuring mechanism. During measuring the trigger signal is generated by shading of a miniature light barrier inside the probe. This guarantees an absolutely wear-free probe with constant reliability even after millions of operation cycles. The switching status is indicated via LED which allows easy control of operation.

There were many reasons for the success of the previous probe and these can be applied to the new design, e.g. the system identifies a broken tool which avoids further damage of the workpiece or machine tool. If the tap drill breaks during threading and the following tap has a collision the consequences are often essential damages on the machine and maybe on an expensive workpiece. With the new Z-Nano such errors will be eliminated.

The Z-Nano can be mounted in vertical as well as in horizontal orientations. Practically proven and optimized measuring cycles for all common control types are included in the delivery program. Especially for the production of large series a time-optimized software is available which enables fast tool breakage detection within 1-2 seconds. Accessories offered by Blum are different mounting sockets, e.g. with nozzle to clean the measuring surface and the tool. Also available is a mechanical chip protection, e.g. for horizontal mounting.

„The probe is delivered with a highly flexible connecting cable and 1.5m of steel mesh. If installation with cable is not possible, e.g. in machines with pallet changer, the probe is also available without cable and IR transmission” Weiland says.

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.
