Spring Manufacturing
Technology
4th, 5th & 6th November 2008
Including Accurate Spring Measurement and
Inspection & Quality Control
Springs
are the most highly stressed manufactured components operating in any mechanism.
As a consequence they are manufactured from the highest strength
engineering materials known to man.
They are critical components requiring a detailed knowledge and
appreciation of their manufacture on the part of all involved in the component
supply chain. This
course will provide that essential understanding in 3 days of the processes used
to make reliable springs.
WHY
~ processes are carried out
WHAT ~ the potential pitfalls, limitations and benefits are
HOW ~ the processes are carried out
WHEN ~ some processes are more appropriate than others
WHERE ~ the critical stages in the manufacturing process are
WHICH ~ order manufacturing processes should be undertaken
Who
Should Attend ~ This
course is most popular with Spring
Manufacturers.
Experienced staff will gain an understanding of the processes used and will
provide answers to those questions you always wanted to ask. New employees will
also profit from the course, but they should have been working with springs for
a few weeks or months to gain most benefit. Raw
Material Suppliers
will learn what should happen to their materials. End
Users
of springs will learn about how their springs ought to have been produced.
Note
:
Practical craft training in spring machine setting or operating is not offered
as part of the course.
