Obsolete Product Manufacture

End users are often faced with the problems of re-tooling old machines or manufacturing products from a bygone era. CSN provide a valuable service for major international cutting tool companies, machine suppliers, agents, distributors & end users by providing a manufacturing source for obsolete standard products or items which can no longer be procured from OEM sources which are no longer operating.

There is a national & international requirement for the supply of equipment that is no longer readily available from the original source. CSN have the capability to provide a solution to this problem by being able to produce from fully detailed drawings or reverse engineer from provided samples. It is the combination of being former employees of one of the world's leading special tool manufacturers & a manufacturing source for major international tooling suppliers for the last 30years.

The 'Selling On' of obsolete production lines to developing countries means that there is also need for a manufacturing source that is familiar with modern & old methodology, technology, machines & machining techniques. CSN has provided that source for several such projects on an international basis both for third party sources & directly to for the new manufacturer.

Such projects include major automotive engine production lines being relocated to the middle & Far East.

Reverse Engineering

Customers regularly request manufacture of products whereby they have a sample but no drawing. CSN have the capability to analyze, measure, draw & reproduce to an exacting standard. Such products as basic boring tools, milling  cutters, feed-out tools and auto-adjust hones have all been produced from a simple request of  'Can you make this, I'm sorry I don't have a drawing'.
