Key Components

Engineered for precision cutting with stable performance, clean edges, and intelligent control.

Integrated 5-Head Edge Processing

  • 5-head integrated configuration for complete edge processing in a single pass
  • Head 1: Bottom edge flat grinding
  • Head 2: High-power blade for 45° bevel cutting
  • Heads 3–4: Precision polishing of the 45° bevel edge
  • Head 5: 45° bevel grooving
  • Upper and lower synchronized belt feeding for firm clamping and stable transportation
  • Reduced material loss and consistent performance when processing large-format slabs
 
 

Pneumatic Clamping & Variable Speed Control

  • Pneumatic switch controls cylinder operation for beam clamping and release
  • Operates with 3 kg air pressure for stronger and more stable slab holding
  • Enhanced clamping performance to improve processing accuracy
  • Control panel with adjustable speed settings for easy operation
  • Smooth speed variation for stable and efficient processing performance

Superior Polishing Quality

Multiple polishing wheels work sequentially to remove grinding marks and improve surface smoothness. The final polishing stage produces a high-gloss finish that closely matches the original surface appearance of the stone or porcelain slab. This ensures premium-quality edges suitable for:

Kitchen countertops
Vanity tops
Stair treads
Window sills
Wall cladding panels
Furniture stone components
