Stainless Steel Compression Spring for the Automotive Industry
Stainless Steel Pollution Control Valve Spring
(click on thumbnail to enlarge) |
This Stainless Steel type 302 spring is used in a
pollution control system in the automotive industry. Rather than calibrate each valve the customer
requires a very tight tolerance for the spring.
Starting with the best available raw material, Maverick coils the
springs to a free length variation of less than +/- 0.004”, and a diameter
variation of less than +/- 0.002”. End
grinding is accomplished using CBN
grinding wheels. CBN
wheels wear very slowly and require no dressing, leading to infrequent and minimal
adjustments to the grinding process.
After grinding all springs are 100% sorted for spring rate and load at
installed length. At all points in the
process a strict Kanban system is maintained to keep tight control of
quality.
