Core Cutting Machine for Sample Preparation – CoreTrim 3000
Rock Mechanics Testing Equipment
Description
CoreTrim 3000 is a fully automatic core cutting machine used for rock sample preparation. It cuts cylindrical core samples in a controlled cutting process and is intended for laboratories working with routine core specimen preparation before testing.
During cutting, an integrated water spray is applied to limit dust. The cutting cycle runs automatically and returns the blade to the starting point (home position) at the end of the cycle.
CoreTrim 3000 is built around electronic control and a simple start procedure, so the operator loads the samples, starts the cycle, and the machine completes the cutting sequence automatically.
Main Features And Capabilities
CoreTrim 3000 combines fully automatic core cutting functions for rock sample preparation with the controls and operating features required for repeatable, production-style lab workflows. Key features and capabilities include:
- Automatic Electronic Control System: Runs the cutting sequence automatically with electronic control for consistent cycle execution.
- Core Diameter Range: Cuts cylindrical core samples from 1.50 to 3.94 in (38 to 100 mm).
- Multi-Sample Cutting Capacity: Processes up to 3 core samples per automatic cycle for 3.94 × 7.87 in (100 × 200 mm) specimens.
- Cutting Angle Accuracy: Provides cutting accuracy up to 0.1° for sample preparation requiring tight angle control.
- Automatic Water Spray Against Dust: Applies water during cutting to reduce dust and support a cleaner cutting process.
- Cycle Time: Completes a fully automatic cycle for 3 samples in approximately 120 s.
- Home Position Return: Returns the cutting blade automatically to the starting point (home position) at the end of the cycle.
How It Works
This core cutting machine follows a simple operating sequence for automatic core cutting during sample preparation:
- Load the core samples into position.
- Start the automatic cutting cycle.
- The machine performs cutting automatically, applying water spray to reduce dust during the process.
- At the end of the cycle, the blade returns automatically to home position.
Applications
CoreTrim 3000 is used for rock sample preparation where cylindrical core specimens must be cut before laboratory testing.
- Rock Mechanics Testing Laboratories
- Core Sample Preparation For Routine Testing
- Geological And Research Sample Preparation Workflows
