Special processing - Import export

The 6, 8 and 10fold Befort magnifiers have been THE magnifiers for precise reading for 30 years. All measuring magnifiers have metal engraved scales. The measuring plates are manufactured and surfacetreated individually using a special process. This timeconsuming precise manufacturing guarantees parallaxfree reading when the magnifier is directly positioned on the object to be measured.

Special processing methods are used to produce what is known as exfoliated graphite or expandable graphite from natural mineral graphite. It has the unique property of abruptly expanding by many times its volume when it is exposed to heat. At Georg H. Luh, we have extensive know-how in this product field and offer the right products for a wide variety of applications with numerous different grades and variants.

Tried and trusted standard types, or individually produced special solutions: No matter what you require – we have the right grade for any application. High quality and individually produced. Brush grades describe the exact composition and the quality of our carbon brushes. With a wide range of formulations and properties, we ensure that the correct carbon brushes are supplied, even for the most special customer requirements. Thanks to special reworking processes such as impregnation, we can alter and improve the properties of MACK brush grades. For example, we can provide increased strength, improved slide characteristics, or lower spark production. MACK carbon brushes are divided into five grade categories: Carbon graphite grades Our graphite carbon grades consist of different types of graphite. In the process, mineral components provide a weak abrasive effect. At low speed and low sparking they are able to grind off slight carbon deposits on the collector. The...
