Key Features
- Full Automation — Motorized cutting at adjustable speeds (0-300 mm/s) eliminates handwheel fatigue. Programmable parameters for high-throughput workflows.
- Wide Section Range — 0.5-100μm with five precision intervals covering diagnostic and research applications from ultra-thin to thick sections.
- Programmable Trimming — 0-500 μm trimming range with automatic specimen feed reduces manual prep time.
- Precision Specimen Control — ±8° XY-axis orientation with 360° rotation, 60mm (70mm is optional customization) vertical stroke, and 20mm (28mm is optional customization) horizontal feed.
- Dual-Mode Feed — 1250μm/s (click), 200μm/s (keep pressing) — single click or continuous press for flexible multi-operator workflows.
- Auto Retraction — 0-220μm/turn on or off specimen retraction protects sections and blade during return stroke.

FAQ
How fast is the automatic cutting?
The RD-355AT features adjustable cutting speed from 0 to 300 mm/s, allowing technicians to optimize for different specimen types and throughput requirements.
What is the difference between full-auto and semi-auto?
The RD-355AT is fully motorized — sectioning and trimming are controlled electronically with no handwheel operation needed. This eliminates operator fatigue and enables consistent speed across all sections.
What sample sizes are supported?
Standard embedding box samples up to Standard Embedding box Maximum 50*45mm, with a maximum section size of 50x70mm. Larger sample holders available through OEM customization.
