1、 Processing depth control: precise gripping mechanical pressure regulation hydraulic closed-loop system from micrometer to millimeter level: real-time feedback through pressure sensors (accuracy ± 0.5N/cm ²), recommended pressure for hard metals (such as stainless steel) is 15-25N/cm ², and soft metals (aluminum, copper) are controlled within 8-12 N/cm ².

Step by step pressure method: During the rough machining stage, progressive pressure is applied (such as increasing by 5N/cm ² every 30 seconds) to avoid instantaneous deformation of the material, especially suitable for thin plates with a thickness of less than 1mm.

Sand Belt/Drawing Wheel Selection Mesh Depth Correspondence Table: Sand Belt Mesh Theoretical Cutting Depth (μ m) Applicable Stage # 60- # 120 50-200 Rough Machining # 240- # 400 20-50 Semi Precision Machining # 600 ↑<10 Mirror Preparation Composite Wheel Layering Technology: Hard core wheels (steel base) are suitable for processing depths greater than 0.1mm, and soft wheels (polyurethane) are used for surface fine adjustment (depth<0.02mm).

Auxiliary process laser ranging calibration: Before processing, use an infrared thickness gauge to scan the plate, and automatically compensate for the Z-axis stroke of the equipment (compensation accuracy ± 0.01mm).

Multi pass strategy: When the depth is greater than 0.3mm, it is processed 3-4 times (reducing by 50% each time), which improves the efficiency by 20% compared to a single deep cutting and reduces sand belt loss.
