...article ] Manufacture: Drilling Produces holes in solid material with drill that rotates as it is fed into a stationary workpiece. Most common drilling machines are shown, but there are others such as deep hole, multispindle and gang drilling machines. Drilling machines can also be used for other operations such as centre drilling, reaming, boring and spot-facing. Cutting...

...article ] [Diagram showing the Cold Wall System] Hot wall system [Images to demonstrate 'Chemical Vapour deposition (CVD)' - see article ] Manufacture: A “high” temperature process. Cheaper, more suitable for mass-production than PVD (Physical vapour deposition), needing no special attachments, clamping or rotation. A batch process. Throughput depends on component...

...article] Manufacture: The basic Nitrotec process has two variations: Nitrotec C and Nitrotec S. Nitrotec C: components are carburised or carbonitrided before the nitriding sequence. Nitrotec S: component is mechanically polished after quenching, followed by the secondary oxidation stage. No organic sealant applied. Nitriding takes place in an ammonia/carrier gas...

...article ] Manufacture: The equipment used in shot peening is essentially the same as that used in shot blasting, except for certain auxiliary equipment made necessary by the more stringent controls imposed in shot peening. The essential elements of a shot peening equipment are a shot-propelling device, a shot-recycling arrangement and a work-handling conveyor. The methods...
