Precautions For Use
01
Installation and Commissioning Specifications
- Foundation and Levelness
The concrete foundation should be constructed according to the equipment model to ensure minimal levelness error. The height difference between the material rack and the machine tool table surface should be controlled within ±0.1 mm, and the center lines should be aligned to avoid cutting offset.
For heavy-duty gantry models, additional reinforcement of the foundation is required, and the bearing capacity should be more than 2.5 times the equipment’s self-weight.
- Electrical and Grounding
Connect to a three-phase power supply, equip with a separate leakage protection device, and ensure grounding resistance is no more than 0.1 Ω.
Check that the wiring of key components such as servo motors and hydraulic pumps is secure to avoid operational failures caused by loose connections.
- Initialization of Hydraulic and Cooling Systems
The hydraulic oil must be filtered before injection. Before the first operation, vent and pressure-test the system. The coolant must be circulated and filtered to ensure a stable flow rate.
02
Preparations Before Operation
- Safety Protection and Training
Operators must wear protective equipment such as cut-resistant gloves, goggles, and earplugs. Jewelry and loose clothing are strictly prohibited.
New equipment requires technical training from the manufacturer, including familiarization with safety devices such as emergency stop buttons and safety light curtains.
- Equipment Checklist
- Mechanical Components: Confirm the tension of the saw blade, the clearance of the guide block, and the wear condition of the tungsten steel clamping plate.
- Electrical System: Test the emergency stop function, protective door interlock (equipment automatically stops when the protective door is opened), and parameter storage function (more than 20 groups).
- Material Adaptation: Select the tooth profile of the saw blade based on material hardness, and adjust the linear speed and feed pressure.
03
Processing Process Control
- Workpiece Clamping and Positioning
The workpiece must be firmly fixed by hydraulic fixtures. For long and slender materials, feeding and receiving racks should be used for support to avoid vibration. When cutting multiple pieces, gaskets should be added to ensure uniform force distribution and prevent the saw blade from swaying.
When cutting at an angle, a laser alignment system should be used to calibrate the angle, with an error of no more than ±0.1°.
- Parameter Optimization and Monitoring
New saw blades require a running-in period: Adjust the feed rate of the first piece to 20% of the normal level, and restore it to normal for the fourth piece. This extends the saw blade’s service life by 20–50%.
Monitor the saw band’s operation in real time. If swing amplitude exceeds ±0.1 mm, or if abnormal noise or sparks occur, stop the machine immediately for inspection.
- Environmental Protection and Safety Compliance
The coolant must pass through multi-stage filtration (metal shavings recovery rate up to 98%). Direct discharge is prohibited. Oily wastewater must be treated in accordance with REACH regulations.
Protective fences should be set up in the cutting area, and non-operating personnel should maintain a safe distance of more than 1.5 meters.
04
Handling of Abnormal Situations
- Common Fault Troubleshooting
- Saw Blade Breakage: Check blade tension, guide block wear, or inclusions in the material. After replacing the blade, it must be re-run-in.
- Cutting Offset: Calibrate the spacing of the guide arms and the levelness of the worktable, and check workpiece clamping.
- Hydraulic Pressure Fluctuation: Clean the relief valve, check for seal leakage, and replace the hydraulic pump if necessary.
- Emergency Response Process
In case of fire or electrical failure, immediately cut off the main power supply, use a dry powder fire extinguisher, and do not use water.
When equipment malfunctions and requires repair, hang a "Do Not Close" sign and ensure repairs are handled by a certified electrician or manufacturer technician.
