QSZQ-1200/1400/1600

Dinosaw Bridge Cutting Machine: Accelerate Lead Times & Save $8,000 in Labor Per Project. For infrastructure markets in the Middle East, SE Asia, and Africa, efficiency is everything. The Dinosaw Bridge Stone Cutting Machine leverages a high-precision oil-immersed roller and linear guide transmission system to eliminate mechanical vibration during heavy-duty tasks. Featuring a 680mm maximum cutting height and Inovance servo motors, it boosts output by 15%, ensuring your projects stay ahead of schedule. This bridge cutter can cut granite, marble, sandstone, quartz, limestone, travertine, basalt, and engineered stone. It excels in producing tombstones, monuments, curbstones, dimensional slabs. Our integrated hydraulic lifting system ensures rock-solid blade stability and micrometer-level depth control, preventing blade deflection in blocks exceeding 500mm. This technical edge compresses a 300-day cycle into 260 days, saving approximately $8,000 in labor costs per project.

The QSZQ series is built for thick stone and monument work: 680 mm cutting height, oil-immersed guide transmission that stays smooth under heavy loads, and PLC cycles the operator sets once and walks away from.

Real Cutting Performance & Key Metrics

Max. Cutting Height

22–30 kW main motors and 850–950 mm lifting travel support thick-stone cutting up to 680 mm for monument blanks, curb stones and architectural components.

Automated Cutting Productivity

PLC automation, stable guide transmission and reduced operator intervention raise heavy-duty cycle productivity by about 15% over conventional bridge cutting.

Positioning & Division

Encoder-based division and infrared laser calibration position repeated cuts without manual measuring.

Oil-Immersed Guide Transmission

Thick cuts amplify vibration through the blade and bridge. The oil-immersed roller and linear-guide transmission keeps movement smooth under heavy load, protecting blade life, flatness and surface quality through long cutting cycles.

Hydraulic Lifting & Guide Columns

Hydraulic lifting and solid guide columns carry the blade smoothly through deep cuts, maintaining a flat cutting plane across thick monument and architectural blanks.

PLC Set-and-Walk-Away Control

Set the cutting dimensions and cycle once, then let the PLC complete repeated cuts without an operator standing at the machine. Long monument and thick-slab cycles continue while one operator supervises multiple tasks.
