SKIVING MACHINES
Skiving is the operation of Reduction of the edge thickness of a leather by removing a layer from the flesh side, so that it can be folded upon itself without thickening.
https://en.wikipedia.org/wiki/Skiving_(leathercraft)
The Skiving Machine reduces the thickness of the leather on the parts that constitute the shoe upper in accordance to the requirements of the shoe model. The bevel or “bevelling” edge is made by cup-shaped knives that rotate at high speed and with preset inclination. The operation can be hand-operating or by templates. Traditional or computerized versions are available.

Technical data
Electro-splindle of the knife with automatic axial compensation, assembled on pre-loaded guides on ball screws. Knife positioning with micrometric precision. Automatic knife positioning after sharpening. Manual knife counter-sharpening device.
Programmable sharpening and dressing according to the metres of processed work to have less wear out of the knife and grindstone. Foot lifter knee switch. Skiving parameters displayed and electronically adjustable. Skiving width: max 20 mm. with standard foot. Feeding of the leather in continuous or adjustable by pedal. Storing of 1000 different kinds of skiving (100 sequences made of 10 different skiving) that can be easily recalled. The stored parameters can be modified at any time. Sequence program to skive work pieces with different skiving. Lighted Graphic TFT (Thin Film Transistor) display able to show both graphically and numerically all the chosen or stored parameters.Feeding of the material by brushless servo motor, adjustable speed from 0 to 80 cm/sec. Waste exhauster with wide container and micro-filter incorporated.
On the traditional machines the adjustments to perform skivings are every time carried out by the operator and require a considerable loss of time and mistakes can be made when adjustments have to be repeated. On the contrary SC VISION, controlled by a computerized system, can store the fundamental data or programs (width, angle and thickness; feeding speed of the piece that is performed etc…..) concerning 1000 different kinds of skivings.
