Diamond wire cutting machine is a precision cutting equipment that uses diamond wire as a cutting tool, mainly used for processing various hard materials.
Diamond wire cutting machine achieves grinding and cutting of hard and brittle materials through high-speed reciprocating or unidirectional cyclic motion of diamond wire, combined with precision mechanical control. The basic principle of diamond wire cutting machine: Diamond wire cutting machine uses diamond wire as the cutting tool, and uses high-speed moving diamond wire to cut materials. The core principles include:
Grinding and cutting mechanism:
The high-speed rotating winding drum drives the diamond wire (usually with a diameter of 0.125-0.42mm and a tolerance of ± 0.02-0.03mm) to perform reciprocating motion, forming a cutting trajectory.
The tension wheel (spring or pneumatic) works in conjunction with the guide wheel to ensure stable tension of the diamond wire, with a cutting accuracy of Ra ≤ 1.6 μ m and a flat surface without broken edges.
Material adaptability:
Can cut conductive and non-conductive materials (with a hardness lower than diamond wire), including monocrystalline silicon, silicon carbide, sapphire, ceramics, glass, rocks, jade, etc.
Suitable for non-destructive cutting of high hardness, high-value, and fragile materials such as magnesium oxide crystals and honeycomb ceramics.
Daily operation standards:
Installation calibration: Before use, it is necessary to calibrate the levelness of the workbench (error ≤ 0.01mm) and the tension of the diamond wire.
Cutting parameters: Adjust the line speed (choose low speed for hard materials) and feed rate (0.1-5mm/min) according to the material hardness.
Maintenance and upkeep:
Regular inspection: Check the wear of the tensioning wheel every 50 hours and replace diamond wires with excessive diameter tolerance.
Cleaning and lubrication: Clean the workbench residue daily and add lubricating grease to the guide wheel bearings.
Troubleshooting
Rough cutting surface: Check whether the diamond wire is worn or the tension is insufficient, adjust the tension to the recommended value (such as 10N).
Wire breakage: Reduce wire speed or feed rate to avoid local overload caused by sudden changes in material hardness.
