Hardened-steel split bands
TRU-FIT split bands (Pat.5,085,535) manufactured by Valley Grinding are available in outside diameter sizes ranging from 3in to 12in. The patented locking device allows the split bands to be installed and removed without having to disassemble heavy shafts and gears saving valuable time.
Superfinished cutting edges reduce friction between bottom band and top slitter, resulting in less blade wear, extended run times, improved cut quality and reduction of dusting.
The use of through-hardened D-2 material improves wear resistance and impact strength for stronger and longer lasting parts. These bands come in single, double or multi cutting edges providing maximized slit positions per unit and are manufactured to customer specifications.
Top slitter blades
Manufactured in-house to precise specifications, Valley Grinding top slitter blades provide a perfect fit, extremely dependable performance and a variety of design options, including:
- Custom-made to OEM specifications and tolerances in order to match existing OEM machine specifications
- Custom holder shapes including custom angles (single or double bevel) or wide rims
- Multiple material types: 52-100, D-2, M-2, A11 to name a few
- Polished secondary angles to reduce roll flair in plastic films and minimize dusting and angel hair fibers
- Superfinished cutting edges
Shear slitting bottom bands
By using American Iron & Steel Institute certified steel, Valley Grinding shear slitting bottom bands eliminate chipping from impurities or gaps and provide consistent wear and run-time whether using a wrap or tangential slitting format.
Available in a variety of materials for all cutting requirements and budgets, Valley Grinding solid shear slitting bottom bands can be manufactured in both US and metric specifications.
Carbide inlay bottom bands
Valley Grinding manufactures carbide inlay bottom bands using pure virgin carbide inserts. These bands offer longer run times, better cut quality, improved surface finish and less wear on the top slitter blades. The perfect balance of cobalt and tungsten results in blades that are safe to run at any speed while maximizing wear resistance.
VG will custom manufacture in single or double cutting edges to meet individual geometric requirements.
Ceramic and tungsten carbide razor blades
Valley Grinding provides both solid ceramic and solid tungsten carbide razor blades in a variety of sizes and thicknesses to meet virtually any slitting need.
The smooth surface of ceramic razor blades provides superior lubricity and reduces friction by up to 24%, making them ideal for film converting or other adhesive applications.
Tungsten carbide blades feature the sharp cutting edges that resist nicking and last many times longer than regular steel blades.
Sheeter knives
Leading the industry in quality sheeter knife manufacturing, Valley Grinding can customize knife angles and materials to provide the cleanest cuts and longest run-time. They also maintain a large inventory of cross cut knives to ensure that product is available upon demand.
