Description

Automatic Precision Grinder & Polisher GHEXA-GRP-EQP-AUT-009

The GHEXA-GRP-EQP-AUT-009 is a high-capacity, three-station automatic precision grinder and polisher featuring a large Φ380 mm disc, designed for superior flatness and efficient preparation of large or multiple samples. With stepless speed control (10–200 rpm), precise timing (up to 999 hours), robust angular contact bearing motor for extended service life, and quick-swap swing-arm disc replacement, it delivers exceptional planeness (<0.002 mm over 20×20 mm area) across a wide range of materials. Capable of handling specimens up to Φ142 mm diameter or rectangular samples with 142 mm diagonal, this machine is the ideal choice for high-throughput grinding and polishing in research institutions, universities, quality control labs, and production facilities working with metals, ceramics, glass, PCBs, optical crystals, refractories, and composites.

Key Applications & Uses

• High-throughput grinding and polishing of large metallographic samples, multiple mounted specimens, or oversized test pieces in quality control and production labs
• Preparation of flat, low-deformation surfaces on metals, alloys, ceramics, glass, refractories, composites, and optical materials (ZnS, Si, etc.) for microscopic and analytical evaluation
• Precision surface finishing of PCBs, electronic components, and optical elements requiring high planeness and minimal subsurface damage
• Batch processing of samples up to Φ142 mm diameter or 142 mm diagonal for microstructure analysis, hardness testing, coating evaluation, and failure investigation
• Supporting materials research, university teaching labs, semiconductor/optics R&D, pharma (implant ceramics/metals), biotech (biomaterial surfaces), and industrial manufacturing requiring consistent, large-area preparation
• Ideal for workflows needing long-duration low-speed polishing or extended unattended operation
