Technology news

The measuring technique based on the principals of laser scanners and diffraction for non contact and in-line measuring of diameters and cylindrical objects such as wire, enamelled wire and monofilaments, has been around for some time. So far however, usually firmly integrated or stationary systems are available. The new hand held portable diameter control unit LMD HO1B addresses this short coming. It is now possible to obtain accurate diameter checks within seconds at virtually any point on or off line with the LMD HO1B. The unit measures cylindrical objects in motion or at 0 speed ranging from 0.03mm to 1.30mm (0.00118" to 0.051") or 0.05mm to 1.8mm (0.00196" to 0.0708") (HO2B). Portable control from Klaus Jakob

A world first from DSE DSE is introducing the first new high voltage continuity tester covering the full surface of a rectangular wire. After introducing a new range of high voltage continuity (HVC) testers last year, DSE has now added a new type of HVC tester made for rectangular wire – HVC 360 PF Flexible – the first in the world. Because of the fast-growing demand for rectangular wire, DSE has now met its customers’ requests to deliver a test solution for rectangular wire. “We look forward to presenting this new solution which is based on the same successful technology we used in the HVC360 Flexible”, says Mr Knudsen, Product Manager at DSE. The HVC tester is a highly useable tool for adjusting the processes and surveying the production of enamelled wire.

This handy unit with its small dimensions can be utilised wherever small diameters need to be checked. It has proven to be quite useful specifically during the string up process, since the wire can be checked quickly and without effort, between the various drawing steps. This ensures mistakes can be caught early, which other- wise would have led to wire breaks or early die wear. Rapid wire checks before and after annealing will indicate tension re- spectively, stretching of the wire.

The new LMD HO1B addresses shortcomings m

Quick and easy diameter checks during the magnet wire production and after each coating process are also possible. The instrument comes equipped with a lithium battery, which provides extensive operating time and a very short recharging process.

New hardness tester from Zwick

Deutsche Edelstahlwerke in Stuttgart, Germany is a member of the Schmolz + Bickenbach AG group of companies which, with 150 years of experience, 11,000 employees and sales exceeding €4 billion, is the world’s largest producer, processor and distributor of special steel long products. The company offers customers a ‘one-stop-shop’ for heat treatment processes including plasma nitriding. Leading major German automotive sports car manufacturers rank amongst their list of clients, and Zwick has equipped the laboratory with all of its hardness testers – the most recent being the premier ZHU250 TOP Universal Hardness Tester. This machine has expanded the capability of the laboratory to carry out Rockwell, Vickers, and Brinell tests, and includes an innovative revolver system incorporating four indenters.
