The Decoiler starts as and when the Coiling Machine
required wire. As soon as sufficient wire in the form of Loop is available, the decoiling
stops, only to start again as required. This intermittent operation is performed
automatically with use of proximity switches and solid-state control panel.
In case the wire gets entangled or cannot be fed for any reason, the Decoiler and
coiling machine motors cutoff automatically, preventing the wire from breaking.
Available in two different versions with different Grinding
Cycles
Crush Grinding and Down Feed Grinding
Model SEG-1 and SEG-3 with Crush Grinding Cycle as the springs in these wire
ranges can be easily ground with this process
Model SEG-12 with an option of Crush Grinding or Down Feed Grinding as with
bigger wire size springs can be ground better with Down Feed cycle and it gives high
production rate with minimum handling of the springs

Crush Grinding:
In this process, distance
between the two grinding wheels is set to the required spring length. Springs are fed
through the loading plate between the grinding wheels. As the desired length is attained,
springs fall through a chute to the bottom from where they may be collected. The removal
of extra material is possible by single pass as well as by multiple pass
Down Feed Grinding:
In this process, the top
wheel has a down feed arrangement. After the springs are loaded and fed between the
grinding wheels, the Down Feed cycle starts. As the cycle proceeds, grinding pressure on
the wheels rises, which increases the current of the spindle motor till it reaches the
preset upper limit. At this point, Down Feed stops and grinding continues in Spark Out.
During Spark Out, current begins to drop gradually, down to the preset lower limit. Then
Down Feed starts again. This cycle continues till the desired spring length is reached.
The setting of cycle is done with the help of scale, dogs and electrical limit switches.
The Down Feed and the loading plate drive are both infinitely variable to suit individual
springs.
