TOOLING


Without ultra-precision tooling, coiling micro wire sizes to extremely precise tolerances would not be possible. KineCoil manufactures and individually inspects its tooling to precision tolerance levels. Kinecoil is ISO 9001:2015 registered and follows strict quality procedures to ensure every piece of tooling functions properly for the customer.  KineCoil offers special natural diamond coiling point tooling to solve the challenge of deflection coiling stainless steel materials encountered when using standard carbide coiling points.

Arbors 

Arbor size is carefully chosen for individual coil configurations and varies with wire size, coil diameter, and material. An arbor that is too small will lead to a bent or kinked end as the coil is cut. Carefully selecting an arbor is a critical part of the coil manufacturing process and KineCoil engineers are well experienced in selecting the proper arbor size for your application.

Coiling Points 

Coiling point selection depends on wire size and wire material. A .003” wire coil will require a .003” coiling point; likewise, a .018” wire coil will require a .018” coiling point. Coiling points are available in both carbide and natural diamond materials. Carbide offers a superior surface finish to help wire easily slide through the tooling. Natural diamond offers superior wear resistance and is less prone to galling or sticking with the coiling material which is inherent with stainless steel and standard carbide tools.

Preliminary Wire Guides 

Preliminary wire guide size selection is not as critical to the forming process since these guides simply help steer the wire into the feed rolls.  For this reason, they are sized standard for the maximum wire size capacity of each machine and can be used for any wire size smaller than that.  Special wire shapes like flat wire may require special preliminary guides.

Final Wire Guides 

Final wire guides are critical to the deflection coiling process. As the coiling wire is pushed forward by the feed rolls it experiences a high compression column load making it highly prone to buckling. The upper and lower final guides are responsible for containing the wire while allowing it to travel easily through the feed rolls. Lower final guides are typically standard for a given wire size. Any .003” wire coil will require a .003” lower final guide; likewise, a .005” wire coil will require a .005” lower final guide. Upper final guides are standard for a range of wire size and coil diameters.

Cutters 

Cutter size is determined by wire size. Typically, cutters are double-ended so customers get two cutting tools in one. Standard cutters work for a range of coil diameters. Special cutters are available for large diameter coiling applications.

Feed Rolls 

Feed rolls are the first critical piece of tooling that contacts the wire under load. The upper and lower feed rolls pinch the wire with just enough force (without damaging the wire) to continuously push it through the final guides, coiling points, and pitch tool while the coiling process takes place. Standard MicroCoiler lower feed rolls come grooved for .0015" to .006" round wire and upper feed rolls are universal for all wire sizes. Smaller feed rolls are available for ultra-small wire applications below .002" wire diameter. Custom feed rolls are also available for shaped and flat wire applications.

Pitch Tools 

Pitch tools typically accommodate all coil sizes and wire sizes. Standard pitch tools can accommodate all round wire sizes for a given machine. Special pitch tools are available for flat and shaped wire applications.
