SYJ-140 High-Speed Diamond Cut-off Saw with Adjustable Speed, Vise, and Three 100mm Diameter Cutting Blades
The SYJ-140 is engineered for efficient rough cutting of a variety of hard and brittle materials including crystals, ceramics, quartz glass, printed circuit boards, rock and mineral samples, as well as metallographic specimens. It is well suited for use in academic, research, and industrial laboratories where precise material sectioning is required.
This high-speed cut-off saw features a stepless speed regulation mechanism that allows the operator to adjust the saw blade’s rotational speed between 650 and 2500 rpm to match the specific cutting requirements of different materials. The machine operates quietly with minimal environmental pollution and includes a built-in cooling water system that recirculates coolant internally to conserve water usage.
Key Features
- Stepless speed regulation from 650 to 2500 rpm for optimized cutting performance.
- Capable of straight and angled cuts with manual feed control for fast cutting speed.
- Includes a vise for secure sample holding during cutting operations.
- Equipped with three types of 100mm diameter cutting blades: electroplated diamond, silicon carbide, and corundum.
- Compact and corrosion-resistant design with low noise and easy cleaning.
- Internal cooling water system prevents water leakage and reduces consumption.
- Suitable for cutting samples up to 25mm thick and 40mm wide.

Typical Applications
The SYJ-140 is ideal for cutting and sectioning hard materials such as crystals, ceramics, quartz glass, printed circuit boards, rock and mineral samples, and metallographic specimens. It is widely used in university laboratories, research institutes, and industrial quality control for sample preparation and material analysis.
Configuration & Operating Notes
Standard accessories include a vise for sample clamping, one saw blade clamping pad, two electroplated diamond saw blades, ten silicon carbide saw blades, ten corundum saw blades, and 100g of cutting coolant powder. Optional geological thin-section cutting fixtures can be ordered separately to enhance precision cutting capabilities.
The machine requires a stable, vibration-free environment free from corrosive gases. Proper grounding of the power supply is essential for safe operation. Cutting speed is manually controlled by pushing the sample forward against the rotating blade. Non-standard fixture pads can be custom designed to meet specific user requirements.
