HLN
Coiling Lathes
The HLN series of coiling lathes are completely electric CNC-controlled machines designed for the manufacture of springs and augers. Designed and built entirely by Memoli, they are an effective and efficient solution capable of machining round, flat, square bars and tubes.
The design of our winding machines starts with the needs of each single Customer: we build machines specifically to achieve high final standards and optimise production costs.
Their strength is not only the final product: thanks to the ‘CNC Coiling Program TouchScreen’, which provides the possibility to save your own designs as repeatable programmes, operation is extremely easy and fast.

Frequently Asked Questions about HLN machines
HLN coiling lathes up to what wire can they machine?
The maximum wire that can be machined on HLN coiling lathes is 80 mm.
Do HLN coiling lathes have variable speed?
Yes, HLN coiling lathes have variable speed.
What is the maximum length of springs that can be made on HLN roll coil winder machine?
The maximum length is one of the essential elements to be defined when purchasing these machines; it is possible to get to machine springs with a maximum length of 6000 mm.
Can HLN coiling lathes handle several variable pitches within the same part?
Yes, thanks to the specially created numerical control, it is possible to vary the pitch of the spring.
Can HLN coiling lathes only process round bars?
HLN coiling lathes can also machine square and flat bar.
Is it possible to create augers?
HLN coiling lathes, through the special feeding system, can process flat bars for creating augers.
Is it possible to wind coils both left and right?
The direction of rotation of the machine is defined when the machine is purchased; it is possible to supply the machine with both directions of rotation.
