Adwantages
Envelope
Handles roll diameters 250–720 mm and lengths up to ≤2100 mm with modular bed widths 1.0 / 1.5 / 2.0 m, enabling phased capacity planning without platform change.
Precision & Geometry
Handwheel feed 1.333 mm per revolution with fine dial increments (~0.01 mm) delivers controlled layer removal, repeatable surface roughness, and reduced rework; defined drawing slope limits ≤14:100 (2 m) and ≤16:100 (1 m / 1.5 m) maintain uniform tension, improve straightness, and minimize deformation or taper defects.
Stability & Energy
External standalone hydraulic station isolates heat and vibration, enhancing system stability, extending component life, and simplifying maintenance; segmented motor architecture (grinding 4 kW, hydraulic 11 kW, roll drive 3 kW) reduces unnecessary peak load, lowers energy per finished piece, and simplifies fault isolation.
Productivity Timing
Engineered cycle speeds (polishing 68 s/m round trip, drawing 26 s/m, feed 17 s/m, return 9 s/m) balance surface quality with throughput and support accurate takt‑time planning.
Maintenance & Support
Accessible layouts, clear motion logic, simple mechanical adjustments, and a one‑year warranty reduce training time, downtime, and total cost of ownership.
