Wide-belt sander SAG1000

stationaryelectricvariable-speed

Product summary
Combines the high-efficiency cold-state wide abrasive belt grinding process with the precision characteristics of conventional grinding-wheel machines for high-yield, high-precision surface processing.

• The SAG series is developed for high-efficiency precision surface grinding of five material categories: HARD, THIN, BRITTLE, SOFT, STICKY. Examples: ceramic substrates, silicon carbide, quartz, crystal, carbon-ceramic, semiconductor materials, titanium, zirconium, magnetic materials, etc.
• The SAG series delivers significantly higher yield than conventional grinding-wheel machines while maintaining comparable precision.
• Cold-state, low-stress grinding controls deformation and edge chipping to improve yield, increase throughput and reduce scrap. Achieves plane accuracy < 5µm and surface roughness < 0.4µm.

SAG series wide abrasive belt rotary table surface grinder

• High-precision wide abrasive belt head paired with a hydrostatic rotary table for efficient, high-precision cold-state grinding.
• Machine bed in HT300 casting, optimized by FEA and subjected to annealing/aging treatment for long-term stability.
• Hydrostatic rotary table with static stiffness 400 kg/µm — wear-free and stable.
• CP-grade heavy-duty linear guides and precision ball screws across the machine to ensure rotational and positioning accuracy.
• Proprietary operating software with ergonomic interface enabling high automation and minimal operator intervention.
• Quick abrasive belt replacement and fast switchover between belt types and grits for rapid production changeovers.

Hydrostatic Rotary Table
High rigidity, high precision and large load capacity; plane accuracy < 5µm to ensure consistent processing performance.

High-precision Wide Abrasive Belt Head
Equipped with a high-rigidity precision grinding spindle with runout within 1µm. Belt linear speed up to 60 m/s with variable speed control (VFD). Quick belt replacement and adjustment in under one minute for efficient, stable cold-state grinding.

In-process Measurement System
Optional high-precision laser in-process measurement integrated with proprietary algorithmic software and closed-loop control to enable automated operation with minimal human input.
