Many people have just returned from enjoyable holiday in the South West of England. But as well as being a major tourist attraction, this region also contains a healthy industry which provides a wide range of machining services.
The company set up in 1999 is a family-run business. It specializes in the machining of various precision parts.
Two years ago the company bought a new machining centre. ‘Much of our work involves machining different sizes of parts and producing large numbers of holes’, says the managing director. ‘This machine centre will help us become more efficient and reduce the level of skill required for certain key operations.’

Concrete is the name of artificial stone. The materials from which concrete is formed are sand, pieces of broken stone and cement mixed with water in suitable proportions. These materials are called ingredients of concrete. The sand and broken stone form the skeleton of concrete. Dry cement is an inert powder, but on the addition of water a chemical reaction takes place.
This causes the whole mix to set and harden forming a solid mix.
Water used in concrete mix is ordinary drinking water. It must be free from any impurities. The amount of water added influences the properties of concrete. Concrete products must be manufactured according with existing standards. Having chosen component materials builders must be well familiar with technology of concrete and use them in correct proportions.
