Evocus Manual Grinding/Polishing Machine (GrindPol200/250/300 Series)
Single-plate metallographic grinding and polishing machines for pre-grinding, grinding and polishing of metallographic specimens.
Microprocessor-controlled variable speed, clockwise or anticlockwise rotation, integrated cooling and three wheel-size configurations.
Manual Grinding & Polishing
The GrindPol200 / 250 / 300 Series is a single-plate grinder polisher designed for pre-grinding, grinding and polishing metallographic specimens. Microprocessor speed adjustment provides a wide rotational-speed range for different specimen-preparation requirements.
The machine is designed for easy operation and reliable performance, making it suitable for metallographic specimen preparation in factories, research institutions and college laboratories.
Key Features
Single-Plate Design
A single grinding and polishing plate supports pre-grinding, grinding and polishing of metallographic specimens.
Microprocessor Speed Adjustment
Microprocessor-controlled speed adjustment provides variable rotational speed according to the selected GrindPol model.
Integrated Cooling System
The cooling system cools the specimen during pre-grinding to help prevent overheating and damage to the metallographic structure.
Bidirectional Rotation
The grinding and polishing wheel can operate clockwise or anticlockwise to support different preparation requirements.
Emergency Stop
An emergency-stop function is included across the GrindPol200, GrindPol250 and GrindPol300 models.
Three Wheel Sizes
Choose from Ø203 mm, Ø250 mm or Ø300 mm wheel diameters according to the selected model.
Three Models for Different Preparation Requirements
GrindPol200
Ø203 mm wheel with an adjustable rotational-speed range of 0–1400 r/min.
GrindPol250
Ø250 mm wheel with an adjustable rotational-speed range of 0–1000 r/min.
GrindPol300
Ø300 mm wheel with an adjustable rotational-speed range of 0–600 r/min.
During pre-grinding, the integrated cooling system helps cool the specimen to reduce overheating. This helps prevent heat-related damage to the metallographic structure during sample preparation.
