Intelligent version servo motor: totally power 68KW drive
Speed: 30 meters per minute, comprehensive speed of 12 meters per minute to 15 meters per minute (depending on the number of holes drilled);
1. C width (80~350) mm, Z width (120~350mm) can be freely transformed;
2. Small edge (8-20mm) and small edge ≤ 0.8 * (waist height -20);
3. Waist height (30-100) mm and waist height ≤ 0.95 * (bottom width - small edge -30);
4. Adjustable plate thickness t (1.0~3.5) mm;
Length and hole position accuracy ± 1mm
Here are some profiles for your reference:
Configuration requirements :
1.Material thickness :1.5-3.5 mm
