LBT1001 Multifunctional Concrete and Rock Core Sample Cutting and Grinding Integrated Machine

The core‑sample cutting and grinding all-in-one machine is an integrated specimen‑preparation device specifically designed for testing concrete, rock, and other construction materials. It combines cutting with dual‑grinding wheels for end‑face flattening in a single unit, enabling the entire process—from raw core samples to standard cylindrical test specimens (for compressive strength, flexural strength, and durability tests)—to be completed in one clamping operation, eliminating the need for secondary transfers and significantly enhancing efficiency while ensuring specimen accuracy.

LBT1001 Multifunctional Concrete and Rock Core Sample Cutting and Grinding Integrated Machine

Description

Product Introduction

The core‑sample cutting‑and‑grinding all‑in‑one machine is an integrated specimen‑preparation device specifically designed for testing concrete, rock, and other construction materials. It combines cutting with dual‑wheel end‑face grinding in a single unit, enabling you to produce standard cylindrical test specimens—from raw core samples to finished cylinders suitable for compressive strength, flexural strength, and durability tests—using just one clamping operation. This eliminates the need for secondary transfers, significantly boosting efficiency while ensuring high specimen accuracy. The machine features a fully enclosed design, low noise levels (<80 dB), and variable‑frequency speed control. Its main motor typically delivers 3–4 kW of power, providing ample drive during simultaneous dual‑blade cutting to prevent jamming or excessive blade wear. Recommended cutting‑blade peripheral speeds are 33–45 m/s, and the grinding power heads each deliver 1.1 kW at 2,800 rpm. Equipped with diamond cutting blades measuring Φ400 × 3.8 × 50 mm, it can process square blanks and cylindrical specimens up to 150 mm in diameter, making it ideal for standard concrete core samples and rock cores. Processing accuracy meets the following specifications: flatness tolerance within 50 mm is ±0.05 mm; surface finish (according to mechanical‑machining roughness standards) is Ra 3.2, satisfying national mechanical‑testing requirements. An automatic feed system allows adjustable feed rates (0.04–0.17 mm per stroke) and supports one‑button cutting settings, enabling unattended operation. Cooling is provided by tap water, effectively reducing dust and lowering temperatures while extending the service life of both the diamond blades and grinding wheels.
