Laser Cutting Machine—DF3015
Complete machine welding and machining
1.1. The machine tool is made of steel plate welded together and annealed to relieve stress, which can greatly improve the stability, durability and precision of the machine tool.
2.2. The flatness and straightness of the bed after finishing are guaranteed to be W0.05mm, and the flatness and straightness of the crossbeam are guaranteed to be ^0.03mm.
Beam characteristics
1. The design of the crossbeam adopts honeycomb structure, which is high strength, high rigidity and light weight, ensuring the superior dynamic effect of the crossbeam.
2. The design employs steel plates with high rigidity for riveting and welding. After one-piece molding, the components undergo rough machining, followed by secondary heat treatment and precision finishing. This process ensures the overall rigidity and machining accuracy of the crossbeam, guaranteeing that it will not deform during normal high-speed operation of the machine tool.
Bed heat treatment
1. Adopting the standard of segmented and intermittent annealing, the annealing time is up to 12 hours, and when the temperature is raised to 540°C, it is kept for 4 hours. The standard of industrial machine tool annealing is strictly followed to ensure the bed body is not deformed, the stress is removed, and the product is durable.

Equipment assembly process
1. Use a high-precision level to adjust the machine tool's level to within 0.1mm accuracy.
2. Use a collimator to adjust the flatness and straightness of the bed and crossbeam guide rails to within W0.05mm tolerance; adjust the flatness and straightness of the bed and crossbeam racks to within W0.02mm tolerance.
3. Use specialized instruments to adjust the bed frame and crossbeam to a 90° angle, ensuring the error is within W0.03mm.
