Consistently Precise Shaped Wire
Turks heads are used for the direct formation of round material to squares, rectangles and special shapes. A turks head machine operates on the rolling mill principle and imparts the same qualities to metal as a rolling mill does: superior surface finish, accurate size and shape, and improved grain structure of the metal. However, turks heads differ from rolling mills in the number and arrangement of rolls. A turks head utilizes two pairs of rolls, one pair is arranged horizontally, while the other is arranged vertically. The material is formed and shaped through the turks head by either a pulling device such as a capstan, or by driven rolls in power-driven models.
Each type of FENN turks head is designed to meet a particular requirement of precision wire or rod shaping. With the exception of power-driven models, all types require a pull-through power source such as a drawbench, bull block, double capstan, a shedding drum or a rolling mill. In both ferrous and nonferrous metal forming industries, turks heads are used as single units and in tandem on common stands for wire and rod shaping.
Size Control
The unique design and construction of interlocking slides permit infinite adjustment of the turks head rolls. FENN has engineered the highest possible bearing capacity using precision heavy-duty bearings based on the physical size of each turks head. Built with extreme accuracy by FENN’s highly skilled craftsman, FENN turks heads (when properly used) form sections to close tolerances.
Surface Finish
Although surface irregularities cause no particular difficulty, a higher quality entry stock will result in a better finished product. It is important to remove oxides and scale as the build up will cause the rolls to wear more rapidly. It is recommended that lime coatings be removed from wire prior to forming as it tends to build up on rolls and causes separation, tolerance changes, as well as bearing overload.
Various Materials
A variety of metallurgical types can be used with a FENN turks head. Contact us today to learn more about your specific application. A few examples of material types can include Steel, Copper, Platinum, Superconducting, Exotic Metals, and Precious Metals.
FENN manufactures a range of precision pull-through and power-driven turks heads with high bearing capacities at high speeds. Our design and manufacturing engineers ensure that our metal forming machines hold close uniform tolerances on shaped wire.
FENN can design and build customized turks head equipment that can act as standalone machinery or be integrated into an existing or new process.
Universal Models
Includes 2 axes of adjustment: up & down, and in & out. Any square or rectangle within the capacity of the turks head can be set up by merely adjusting the position of the rolls; easiest for set up of standard width and thickness.
Plain-Type Models
Includes 4 axes of adjustment, each roll moving independently. Plain models are best for producing special shapes, as rolls are set up directly in line with each other.
Combination Models
Includes 6 axes of adjustments. Can be used as either a U-type or P-type turks head. Provides the most flexibility in setting up the rolls.
To obtain high production speeds and hold tolerances within acceptable limits, certain operation rules must be followed. Proper application of the machine equipment is important. The turks head is not intended to be a substitute for a rolling mill, however it can be combined to accomplish certain applications. Particular fundamental rules are applicable to both machines where size control, surface finish, accessories or combination use is applied.
