Application
The MLY·150 Hydraulic Roller Grinding and Hydraulic Fluting machine is a special-purpose equipment designed for polishing and fluting large-scale flour mill grinding rolls. The Hydraulic Fluting machine is widely used in flour milling plants for reconditioning and surface processing of roller mill rolls to ensure stable grinding performance and extended service life.
The Hydraulic Fluting machine of a machine bed, worktable, front cover, hydraulic system, electrical system, headstock, grinding unit, polishing system, and cooling system, all integrated into a compact and optimized structure.
Features
Compact and optimized design with stable performance, easy operation, and convenient maintenance.
Hydraulic-driven worktable ensures smooth movement, low noise, fast return speed, and high production efficiency.
Independent indexing and grinding transmission systems simplify the structure, ensure accurate indexing, and allow easy adjustment and reliable operation. Grinding speed is adjustable via a dedicated motor reducer system.
Hydraulic system adopts a plate-type connection structure, reducing piping, simplifying disassembly, and minimizing leakage risk.
Key systems including hydraulic unit, electrical system, and grinding motor are integrated within the machine body, saving space, improving sealing performance, and enhancing overall appearance.
Worktable reciprocation, indexing, tool lifting, and guideway lubrication are all hydraulically controlled, improving automation level, reducing labor intensity, and enhancing fluting and polishing quality.
Overall machine design is highly functional, easy to operate and maintain, with a streamlined and aesthetically pleasing appearance.
