LS-TRA-2 PLC-Controlled Semi-Enclosed Precision Sawing Station
LS-TRA-2 PLC-Controlled Semi-Enclosed Precision Sawing Station is a asphalt specimen preparation equipment for ASTM D5361 workflows. Engineered with HGW linear guides and a high-precision stepper motor feed (≤ 100mm/min), the LS-TRA-2 delivers sub-millimeter accuracy for both cylindrical (φ101.6/φ152.4mm) and large slab (up to 400x150mm) specimens. Integrated pneumatic clamping with pressure monitoring ensures operator safety and specimen stability during heavy-duty diamond cutting.
Intelligent PLC-Driven Feed Logic
The LS-TRA-2 utilizes a specialized industrial PLC and stepper motor drive to automate the cutting process. Technicians can set exact feed rates (0–100mm/min) tailored to specific mix stiffness, achieving a lateral swing-free operation on high-precision linear guides for superior specimen surface planarity.
Pneumatic Safety Guard System
Equipped with integrated pneumatic holders and real-time pressure monitoring, the system will not initiate the 1400 r/min diamond blade unless safe clamping pressure (0.6-0.8 MPa) is confirmed. Dual-button 'dead-man' start logic ensures hands are clear of the cutting zone at all times.
High-Capacity Symmetrical Cradle
The workstation features adjustable mounting blocks for diverse specimen geometries. It supports automated trimming of large-format slabs up to 400mm width and 150mm thickness, as well as rapid-clamping of φ101.6mm and φ152.4mm Superpave gyratory specimens.
