ABRASIVE NAUMKEAGS FOR SHOE MANUFACTURING AND REPAIR

In the shoe finishing stage, precision makes the difference between an average quality product and a piece of excellence.

Among the abrasive tools used on machinery for shoe factories, sole factories, heel manufacturers, orthopedic labs, and shoe repair shops, Naumkeags represent an excellent solution for sanding and finishing soles, heels, wedges, as well as resoling and custom orthopedic shoes and orthotics.

Why Does the Circular Shape of Naumkeags Make a Difference?

Naumkeags feature a distinctive circular design, engineered to fit perfectly onto the rotating shafts of finishing machines. This structure provides key operational advantages:

• Homogeneous and continuous processing: a 360° uniform rotation ensures constant material removal, preventing grooves or uneven surfaces.

• Maximum ergonomics on curves: the rounded shape easily follows the sinuous lines of the footwear, smoothly working on edges, arches, and heels.

• Uniform abrasive wear: the absence of sharp edges distributes wear evenly across the entire working surface, extending the tool life.

Main Applications: What Are Naumkeags Used For?

In technical detail, Naumkeags are specifically used for processing contoured, concave, and hard-to-reach areas during footwear manufacturing and repair:

• Sole Finishing: perfect for sanding, shaping, and finishing the inner arch and concave section of the sole.

• Preparation for carding and gluing: the rounded shape allows the removal of the surface layer even on shaped areas.

• Shoe repair and resoling: ssential in shoe repair shops for removing old worn layers, leveling newly applied half-soles, shaping top lifts, and preparing the bottom before gluing.

• Heel and edge finishing: allows precise shaping and finishing of contours prior to the final brushing and polishing stages.

• Orthopedic footwear processing: widely used for precise fine-shaping of custom insoles, arch supports, and orthotic lifts.

How to Choose the Correct Abrasive Grit Size

Choosing the right grit size depends on the type of material and the required aggressiveness of stock removal:

• Coarse Grit (60): ideal for roughing and fast material removal.

• Medium Grit (80 – 120): used for precision shaping, edge leveling, and preparing surfaces for gluing.

• Fine Grit (150 – 180 – 220): essential for a smooth final finish prior to dyeing or polishing.

Why Choose CTA Calflex Naumkeags?

Using premium quality abrasive grains ensures a consistent cut, prevents overheating of the workpiece, and extends the tool’s service life.
