Hydraulic wire drawing machine is mainly used for grinding rollers of flour mills, feed mills, oil mills and wineries, grinding and wire drawing of crushing rollers of crushers. After a period of wear and tear of the crushing roller, the teeth will be blunt. In order to restore the openness of the roller surface, it mast be polished or finely turned with a lathe before wire drawing. It is necessary special equipment for grease processing enterprises.

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
ccAccessible layouts, clear motion logic, simple mechanical adjustments, and a one‑year warranty reduce training time, downtime, and total cost of ownership.
