We are also using only high quality materials, to ensure that our gear system can stand tough against gear failure, wear and tear as well as lasting the longest from any coiling system on the market.

 

Quick Changeover For All Bonnell
Spring Types
The machine is intended to make fast changes on the spring outside diameter, spring height and spring turns. It is suitable for all wire thicknesses between 1.9 to 2.4 mm. The machine design allows to produce
springs with 4, 5, or 6 turns.

 

Spectacular Features x Automatic Lubrication
System
The automatic lubrication system ensures a periodic oiling of 20 points on the machine with the option to set the desired time frame for each lubrication through the touch screen display. The oil tank capacity for the
coiling section holds 3 liters. There is no more need for manual lubrication needed.
