During heat treatment, many features of machined components suffer distortion. If the position or dimensions of a groove are critical to the performance of a hardened component.
David Richards can offer a simple solution to this problem - Hard Grooving -
Based on the Top Notch system, David Richards supply grooving tools in a wide range of [...]
BORING - HARDENED STEEL
Internal Grinding is time consuming and expensive. For small bores David Richards provide a simple solution
Hard Boring
For bores down to 10 mm David Richards provide cost effective triangular cutting tool inserts with 3 PCBN edges in grades DR-50/450 and a range of boring bar tool holders to suit - steel shank boring [...]
What is POLYCRYSTALLINE DIAMOND?
Diamond is the hardest, most abrasive-resistant, material known to man. These properties make diamond an ideal cutting tool. Within the crystal structure, however, fracture planes, used by the diamond cutter to produce the gem diamond from the rough, can cause catastrophic breakage of the tool edge, when subjected to impact.
DR-PCD tools incorporate [...]
What is (PCBN) POLYCRYSTALLINE CUBIC BORON NITRIDE?
Diamond, cubic carbon, is the hardest, most abrasive resistant material known to man. It is therefore an ideal tool material. Unfortunately, in the presence of heat and iron, nickel or cobalt, diamond transforms to hexagonal form, graphite. This is why ferrous materials are not generally machined [...]
