CoreTrim 3000 – Core Cutting Machine
Description
CoreTrim 3000 is a fully automatic core cutting machine for rock sample preparation. It cuts cylindrical core samples in a controlled cycle and is built for laboratories that trim core as routine work rather than occasionally.
The operator loads the samples and starts the cycle; the machine cuts, sprays water through the cut to hold the dust down, and returns the blade to its home position at the end. Because the sequence is under electronic control rather than under the operator's hand, the same cut comes out the same way on the first sample of the morning and the last one of the day, which is what keeps specimen length and squareness consistent across a batch.

CoreTrim 3000 Main Features and Capabilities
The features below are the ones that decide throughput and how much attention the machine needs while it runs.
Automatic control
An electronic control system runs the cutting sequence from start to finish, so the cycle is executed the same way every time.
Core diameter range
Cuts cylindrical core samples from 1.50 to 3.94 in (38 to 100 mm).
Three per cycle
Processes up to three core samples in one automatic cycle for 3.94 × 7.87 in (100 × 200 mm) specimens.
Cutting angle accuracy
Holds cutting accuracy to 0.1°, which is what matters when the cut face has to be square to the core axis.
Water spray
Water is applied automatically during cutting to reduce dust and keep the cut clean.
Home position return
The blade returns automatically to the starting point at the end of the cycle, ready for the next load.
How the CoreTrim 3000 Works
The operating sequence is short, and only the first step needs the operator.
Step 1
Load the core samples into position.
Step 2
Start the automatic cutting cycle.
Step 3
The machine cuts automatically, applying water spray to reduce dust as it goes.
Step 4
At the end of the cycle the blade returns automatically to home position.
A full cycle on three specimens takes about 120 seconds, so an operator can prepare the next set of cores while the machine works through the current one.
CoreTrim 3000 Applications
The machine is used wherever cylindrical core has to be cut to length before a test, and the volume is high enough that cutting by hand becomes the slow step.
Rock mechanics laboratories
Preparing core specimens for strength and deformation testing.
Routine core preparation
Day to day trimming of core to a set length for repeat testing.
Geological and research work
Sample preparation workflows where a consistent cut matters more than speed alone.
CoreTrim 3000 Technical Specifications
Check the core diameter range against the sizes you drill, and the supply against your laboratory: the machine is built for 220 V AC at 50 to 60 Hz.

Where the cutting is occasional and by hand, the rock core cutter and masonry saw covers the same step; once the core is cut to length, the NG-CoreGrind 2000 takes the ends down flat and parallel.
