Diamond Segment for Granite Cutting

250-3000mm

Industrial diamond segments engineered for granite blades. Designed to cut hard stones like granite, basalt, and sandstone, they are brazed to a blade core to produce smooth, straight kerfs. These segments deliver faster feed rates, longer service life, and chip-free edges, reducing rework and total costs. Their optimized geometry and metal bond control heat and prevent glazing, ensuring consistent thickness and clean finishes.

FAQs

Common Questions About Diamond Segment for Granite Cutting

How do I choose the segment bond for granite?

The choice of segment bond is critical for performance. A medium-hard metal bond is the best starting point for most common types of granite.
  • Start with medium-hard metal bond for common granite
  • Go harder for dense/abrasive granite; softer for brittle/polished types
  • Pair with steady wet cooling + balanced feed to keep diamonds cutting
Benefits:
  • Cleaner edges, fewer chips
  • Stable thickness across slabs

Which diamond grit works best for slab cutting?

Selecting the right diamond grit balances cutting speed with surface finish. For granite slab cutting, a medium-coarse grit is generally the most effective choice.
  • Medium-coarse grits (e.g., 30/40) = fast penetration + clean kerfs
  • Finer grits improve finish but slow feed; coarser grits risk chipping
  • Match grit to slab thickness + finish goals; ensure adequate coolant
Benefits:
  • Balanced speed/finish
  • Consistent efficiency through long runs

Why do edges chip, and how can I stop it?

Edge chipping is a preventable issue often caused by operational factors. By controlling key parameters, you can achieve clean, chip-free cuts consistently.
  • Common causes: glazed segments, excessive RPM, poor coolant
  • Use an “open” bond, keep RPM within limits, ensure wet cooling both faces
  • Stabilize feed, avoid sharp direction changes, check blade runout
Benefits:
  • Chip-free edges
  • More predictable, straighter kerfs

Wet vs dry cutting for granite segments?

For granite, wet cutting is overwhelmingly the recommended method as it enhances both performance and safety. Dry cutting should be reserved for very specific, limited situations.
  • Wet cutting is standard: cools bond, clears swarf, keeps diamonds sharp
  • Dry cutting raises heat/glazing—limit to short, light-pressure tasks
  • If dry: reduce RPM, shorten passes, add cooldown cycles
Benefits:
  • Higher feed + longer life
  • Safer, cleaner cuts

How do I set RPM and feed without overloading?

Finding the optimal RPM and feed rate is key to avoiding overload and maximizing tool life. Using the blade's line speed as a starting reference is a reliable method.
  • Use line speed: m/s ≈ π × blade diameter (m) × RPM / 60
  • Stay under marked max; ramp feed until segments run cool + kerf is straight
  • If heat/squeak: reduce RPM/feed, increase coolant, check tension/runout
Benefits:
  • Protects segment life
  • Maintains straight, clean kerfs

How can I extend segment life on granite?

Maximizing segment life involves a combination of correct operational practices and proper maintenance. The goal is always to ensure the diamonds are cutting efficiently rather than rubbing.
  • Ensure adequate wet cooling; avoid “rubbing not cutting”
  • Light dressing if glazing; prefer steady feed over peak pushes
  • Clean slurry to prevent re-cutting debris; verify flanges/traceability
Benefits:
  • Higher throughput
  • Longer tool life
