PRESI EVO 500 Fully Automatic Vertical Abrasive Cutting Machine

Overview

The PRESI EVO 500 is a high-capacity, fully automatic vertical abrasive cutting machine engineered for precision sample preparation in demanding metallurgical, materials science, and quality control laboratories. Designed around a rigid cast-iron frame and vertically oriented abrasive wheel architecture, it employs controlled torque delivery, real-time motor load monitoring, and adaptive feed-rate compensation to minimize thermal distortion, subsurface damage, and kerf width—critical parameters for subsequent metallographic analysis, SEM/EDS specimen preparation, or mechanical testing. Its vertical configuration enables stable handling of large-section specimens—including billets, weld joints, turbine blades, and composite laminates—while maintaining consistent linear blade velocity across varying wheel diameters via variable-frequency motor control. The system operates under ISO 12100–compliant safety architecture, integrating light curtains, interlocked hydraulic door actuation, and emergency stop redundancy suitable for both ISO/IEC 17025-accredited labs and regulated production environments.

Key Features

• 11 kW variable-frequency AC motor delivering constant torque across 1,000–4,500 rpm range; maintains optimal peripheral speed as blade diameter decreases due to wear.
• Motor-load-responsive feed control: automatically reduces preset feed rate by 50% upon overload detection, then incrementally restores +20% per stable cycle—ensuring continuous process integrity without operator intervention.
• Electrically actuated, counterbalanced safety door with position-sensing interlocks; opens/closes smoothly to reduce ergonomic strain during high-frequency specimen loading.
• Modular anodized aluminum worktable with removable stainless-steel top plate—designed for corrosion resistance and field-replaceability after extended abrasive exposure.
• Three operational modes: (a) Hand-guided assisted cutting with real-time spindle RPM and motor load visualization; (b) Fully automatic single/sequential cuts with pulse-cut modulation to suppress vibration-induced microcracking; (c) Password-protected programmable method execution from onboard database (100 slots).
• 15.6-inch industrial-grade TFT touchscreen with IP65-rated front panel; supports English, French, German, Spanish, and Chinese UI languages; stores full parameter sets including wheel type, coolant flow rate, dwell time, and post-cut rinse duration.

Sample Compatibility & Compliance

The EVO 500 accommodates specimens up to 500 mm in height and unrestricted width/depth when mounted on its front- and side-access platform design—facilitating overhead crane integration for heavy forgings or castings. It accepts standard ISO 5211-compliant abrasive wheels ranging from 250 mm to 500 mm in diameter, including diamond-impregnated, CBN, aluminum oxide, and silicon carbide variants—enabling optimized selection based on material hardness (e.g., WC-Co sintered carbides vs. austenitic stainless steels). All cutting protocols adhere to ASTM E3–22 (Standard Guide for Preparation of Metallographic Specimens) and ISO 14489 (Metallographic Sampling and Sectioning), with audit-trail-capable parameter logging aligned with GLP and GMP documentation requirements. CE marking confirms conformity with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.

Software & Data Management

The embedded control firmware supports traceable method management through hierarchical user access levels (Operator, Technician, Administrator), enforced via SHA-256 password encryption. Each executed cut logs timestamp, wheel ID (via optional RFID reader), motor current profile, feed rate history, and coolant pressure—exportable via USB 3.0 or Ethernet to LIMS-compatible CSV or XML formats. Optional software module “PRESI LabLink” enables remote method synchronization across multi-unit installations and integrates with electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11 for signature capture and audit trail retention. No cloud dependency: all data remains on-device unless explicitly exported.

Applications

• Preparation of cross-sections from aerospace nickel-based superalloys (Inconel 718, Waspaloy) and titanium alloys (Ti-6Al-4V) for grain structure analysis and phase quantification.
• Routine sectioning of welded joints in pipeline steels (X70, X80) per API RP 2X and ISO 15614-1 standards.
• High-precision slicing of ceramic matrix composites (CMCs) and silicon carbide substrates prior to FIB-SEM lamella extraction.
• Controlled segmentation of geological core samples containing pyrite or quartz veining, minimizing artifact generation during brittle-phase fracture.
• Production-line QA sampling of additive-manufactured parts (SLM, EBM) where layer boundary integrity must be preserved for OM/SEM evaluation.

FAQ

What safety certifications does the EVO 500 hold?
It carries CE marking per Machinery Directive 2006/42/EC and complies with EN ISO 12100:2010 (risk assessment), EN 60204-1:2018 (electrical safety), and EN 13218:2002 (abrasive wheel machinery requirements).
Can the EVO 500 integrate with existing laboratory informatics systems?
Yes—via Ethernet or USB, it exports structured cut logs compatible with major LIMS platforms and supports optional LabLink software for ELN synchronization and 21 CFR Part 11–compliant electronic signatures.
Is coolant system compatibility standardized?
The machine features dual independent coolant circuits (high-pressure spray + flood cooling) with adjustable flow control; compatible with water-soluble oils, synthetic coolants, and low-toxicity formulations meeting ISO 6743-7 specifications.
How is blade wear compensated during long-duration cuts?
The VFD continuously adjusts motor frequency to maintain constant peripheral velocity (m/s) regardless of wheel diameter reduction, while real-time torque feedback modulates feed rate to sustain optimal chip load and surface finish.
What maintenance intervals are recommended for routine operation?
Daily: coolant level and filtration check; weekly: guide rail lubrication and door seal inspection; biannual: spindle bearing preload verification and encoder calibration—documented in the included service manual compliant with ISO 13849-1 PL e performance level requirements.
