FAQ's of Arsenal Bulgaria FU-251 Universal Milling Machine:
Q: How do I operate the Arsenal Bulgaria FU-251 for universal milling tasks?
A: Operation of the FU-251 is fully manual. Set the desired speed and feed using the 12-speed and 12-feed gears, securely clamp your workpiece on the 1250 x 250 mm table, select the appropriate spindle (horizontal or vertical), and adjust the table position using X, Y, and Z handwheels for precise machining.
Q: What types of milling processes can the FU-251 handle?
A: The FU-251 supports various milling processes such as face milling, end milling, slotting, drilling, and angular cutting, due to its universal spindle arrangement and wide travel capabilities on all axes. This versatility makes it suitable for both production and repair operations.
Q: When should I use the horizontal versus the vertical spindle on this machine?
A: Use the horizontal spindle for operations requiring greater rigidity or when working with large or heavy cutters, such as slab and side milling. Switch to the vertical spindle for precise contouring, drilling, or when using end mills and other vertical cutters.
Q: Where is the optimal placement for the FU-251 in a workshop?
A: Position the milling machine on a stable, level floor with at least 2250 x 1750 mm of free space to accommodate its footprint. Ensure sufficient clearance for table movements and operator access. Its centralized lubrication system and fitted coolant make it suitable for industrial environments.
Q: What are the main benefits of using the Arsenal Bulgaria FU-251?
A: Key benefits include universal operation (supporting both horizontal and vertical milling), robust build for heavy-duty work, flexibility from multiple speeds and feeds, and extended service life due to centralized lubrication and an integrated coolant system. These features make it dependable for demanding applications.
Q: How does the centralized lubrication and coolant system contribute to machine longevity?
A: The centralized lubrication system ensures key sliding and rotating components are consistently lubricated, reducing wear and maintenance. The fitted coolant system helps disperse heat during intensive milling, maintaining dimensional accuracy and protecting both tools and workpieces for long-term productivity.
