Sharkcutting 150mm M-288 Industrial Rotary Slitter Blade

Overview of the M-288 Precision Blade

Why Choose Sharkcutting for Your Slitting Needs

We prioritize high-tolerance manufacturing and reliable material selection so your production lines experience minimal downtime.

• • Extended Tool Life: High-grade alloys resist abrasive wear, keeping your edges sharper for longer production cycles.
  • Precision Edge Grinding: Mirror-finish bevels minimize dust, edge burrs, and material drag.
  • Tight Tolerances: Strict concentricity and flatness controls eliminate high-speed wobble.
  • Direct Manufacturer Supply: Consistent quality control, standard stock availability, and global dispatch.

Technical Specifications of the 150mm M-288 Blade

Standard Dimensions and Bore Configurations

We manufacture every 150mm circular slitter to maintain tight concentricity and dimensional stability under continuous operational loads.

Material Options: Tungsten Carbide, HSS, and D2/SKD-11

Selecting the correct alloy ensures maximum wear resistance and reduces blade changeover downtime. Consult our detailed slitter blade material guide to match specific core materials to your production requirements:

• • Tungsten Carbide (TC): Delivers superior hardness and ultra-long wear life. Ideal for highly abrasive substrates, films, and continuous high-speed runs.
  • High-Speed Steel (HSS / M2 / M35): Provides an optimal balance of toughness and edge retention. Performs exceptionally well in high-volume paper and general packaging conversion.
  • D2 / SKD-11 Tool Steel: High-carbon, high-chromium steel offering high compressive strength and dependable wear resistance for general industrial slitting.

Surface Treatments and Coatings for Extended Tool Life

To prevent material buildup, minimize friction, and extend runtime between sharpenings, we provide advanced edge and body finishes:

• • Titanium Nitride (TiN): Reduces friction and significantly increases surface hardness for abrasive slitting.
  • Titanium Aluminum Nitride (TiAlN): High thermal stability for dry, high-speed slitting where friction heat degrades standard tool steel edges.
  • Diamond-Like Carbon (DLC): Ultra-low friction coefficient designed to eliminate adhesive pickup and polymer buildup during film slitting.
  • Mirror Polish Finish: Ra < 0.2 µm edge finish to ensure clean, burr-free cuts and minimal dust generation.

Edge Geometries and Slitting Methods

Depending on your web material and machinery, we tailor the bevel profile and edge geometry to match specific slitting methods:

• • Shear Slitting: Configured primarily as a top shear slitter knife, the M-288 runs against a powered bottom anvil knife. Pairing our high-precision shear slitting knives with a dialed-in shear slitting top knife bevel angle eliminates edge burrs and dust generation on tough webs.
  • Razor Slitting: Ground to an ultra-thin, razor-sharp edge profile for clean penetration in thin films, foils, and multilayer laminates.
  • Crush / Score Slitting: Built with heavy-duty radiused bevels to crush-cut non-wovens and label stocks against hardened backup sleeves without micro-chipping.

Precision Tolerances and Hardness

Consistent slitter performance relies on extreme manufacturing tolerances. We grind every 150mm circular slitter knife to strict dimensional standards to ensure flawless runout control at high line speeds:

• • Surface Flatness: Held within ±0.002 mm (±0.00008") to prevent blade wobble and edge overlap variations.
  • Concentricity & Runout: Radial runout maintained under 0.005 mm for vibration-free operation on high-speed slitter-rewinders.
  • Hardness Ratings: Heat-treated to 62–64 HRC for high-speed steel and up to 89–92 HRA for solid tungsten carbide, delivering superior wear resistance and extended service intervals.

Industrial Applications for M-288 Blades

Flexible Packaging and Plastic Film Conversion

For continuous web slitters running flexible substrates, edge clean-cut quality determines roll unwind performance. Our M-288 rotary slitter knife 150mm OD configuration excels in continuous film processing lines and high-output packaging machine knives operations:

• • BOPP, PET, and PVC: Eliminates micro-tears and fringe stretching during high-speed rewinding.
  • Multilayer Barrier Films: Delivers precise score and shear cuts without delaminating sensitive food and medical barrier layers.
  • Stretch and Shrink Wraps: Prevents blade gumming and edge welding on low-density polyethylene (LDPE) and LLDPE.

Paper, Board, and Label Stock Processing

Dust and dull edges cause major downtime in paper slitting and label finishing. We grind our 150mm circular slitter knives to ultra-tight tolerances to ensure pristine, fiber-free separation:

• • Pressure-Sensitive and Label Stock: Shears cleanly through face stocks and adhesive coatings without blade buildup.
  • Coated and Thermal Paper: Minimizes abrasive wear when cutting clay-coated, silicone-treated, or specialty thermal grades.
  • Folding Cartons and Kraft Paper: Handles thick calipers while maintaining dimensional accuracy and edge sharpness.

Specialized Metal Foils and Non-Woven Materials

Converting abrasive or ultra-thin webs requires maximum edge retention and rigidity:

• • Battery and Metal Foils: Provides chip-free slitting on thin aluminum, copper, and lead foils used in electronics and energy storage.
  • Non-Woven Fabrics: Easily cuts spunbond, meltblown, and spunlace materials used in hygiene and medical filtration lines without frayed fibers.
  • Technical Laminates: Withstands continuous high-tension slitting of composite foils and reinforced backing materials.

Machine Compatibility and Customization

Direct OEM Interchangeability

Our slitter-rewinder blade M-288 tooling easily integrates across top global machinery brands:

• • Converting platforms: Direct replacement for major European, American, and Asian slitter-rewinder models.
  • Shaft systems: Engineered to fit standard pneumatic shafts, mechanical expanding arbors, and multi-knife blocks.
  • Shear and score assemblies: Full alignment with standard top blade holders and driven bottom counter-knives.

Custom Bore Sizes, Keyways, and Bevel Angles

Non-standard setups require exact tolerances to avoid blade flutter. Through our dedicated OEM and ODM customization services, we tailor every dimension of the 150mm circular slitter to match your arbor setup:

• • Arbor Bores: Standard circular bores, splined configurations, or precision ground IDs with micro-tolerances.
  • Drive Keyways: Single, dual, or custom pinholes engineered to prevent slippage during high-torque acceleration.
  • Bevel Profiles: Single-bevel, double-bevel, hollow-ground, or compound-angle profiles matched directly to your film, foil, or paper stock.
