Glossary

It is not always possible to avoid specialist terminology – particularly when it comes to technically complex topics like mechanical engineering. The following, alphabetically sorted glossary offers quick assistance if there is a term you do not understand.

DAkkS

The German National Accreditation Body (Deutsche Akkreditierungsstelle, DAkkS) is a private sector organization that carries out the role of the national accreditation body for the Federal Republic of Germany.Our calibration laboratory is certified according to DAkkS

Granite

Granite is a magma-like plutonic rock (plutonite). It contains quartz and feldspar as well as dark (mafic) minerals, primarily glimmer. The chemical and mineralogical composition of granite corresponds to the volcanic rhyolite.

Granitmessplatten

Granitmessplatten werden aus dunklem Naturhartgestein hergestellt. Sie dienen in der Werkstatt, im Messraum oder im Labor als Basis für Montage- und Kontrollarbeiten. Die Genauigkeit der Oberfläche von Messplatten aus Granit wird nach DIN 876 definiert. Granitmessplatten können auch mit Gewindebuchsen zum Befestigen von Werkstücken sowie mit Stahl- und T-Nut-Schienen zur Befestigung und Führung von Reitstöcken und dergleichen ausgestattet werden. Sie können sowohl einzeln als auch als Set mit Untergestell aus Profilstahl oder mit einem Schrankunterbau aus stabilem Stahlblech geliefert werden. PLANOLITH bietet Granitmessplatten in den kurzfristig lieferbaren Standardgrößen von 250 x 250 mm bis 2000 x 1000 mm. Außerdem kann jedes Zwischenmaß sowie Größen über 2000 x 1000 mm bis zu einem Stückgewicht von 30 t geliefert werden.

Lapping

Lapping is an exciting mechanical, potentially also manually conducted manufacturing process to smooth surfaces. Lapping uses a mix of lap powder and water or oil. In contrast to polishing, in which the abrasive grain is embedded, work is conducted with loose grains. As a result, even with relatively coarse grains, it is possible to achieve high surface qualities because of the limited amount of material.

Linear guide

A linear guide is a guide equipped with rolling elements or slide bearings. A type of construction often applied in such a machine element is the draw-back of the rolling elements (recirculation).

PLANO-CERAMICS

A composite material, developed by PLANOLITH and patented, from natural hard stone and ceramic which, through a special adhesive technology, is permanently and workably attached. The material has a high level of hardness and service life as well as a limited roughness and does not absorb any water.

Plutonite

Granite in its diverse manifestations and compositions, formed millions of years ago under the Earth’s crust, where magma slowly solidified. The magma was located under the Earth’s surface at a depth of over 2 kilometers. For this reason, granite is considered an alkaline abyssal rock. Its technical term is “PLUTONIC ROCK”.
