BV210 “Standard” model

Product catalog summary

Overview: The BV series of CNC vertical lathes by BIGLIA are designed for cost-effective chuck machining with integrated automation. These machines are built on BIGLIA's tradition of horizontal CNC lathes and are equipped to handle automatic loading and unloading of parts, making them suitable for unmanned operations.

Main Features:

Rigidity and Stability: The machines feature robust mechanical parts, including the structure, guideways, ballscrews, spindles, and turret, ensuring high chip removal rates. They are available with ASA 6” (BV210) and ASA 8” (BV315) spindles, accommodating various chuck sizes and pallet systems.
Productivity: Fast indexing servo turret and high acceleration of axes and spindles reduce idle times, enhancing performance. The well-proportioned machining area facilitates quick tooling-up operations and efficient chip removal.
Accuracy: Thermal stabilization of heat sources, spindle, and turret, along with linear scales, maximizes machining accuracy.
Environment-Friendly and Cost-Saving: Grease-lubricated guideways reduce coolant contamination and disposal costs.

Versions:

BV210/315: Standard machine.
BV210M/315M: Equipped with live tools and C-axis.
BV210Y/315Y: Equipped with live tools, C-axis, and Y-axis.

Technical Specifications:

Spindle: High torque and power at low range, with a combination of ball and roll bearings for powerful cutting and high accuracy.
Turret: Fast indexing with a 3-ring Hirth coupling for maximum rigidity. Equipped with live tools for milling, boring, and tapping operations.
Axes: X-axis stroke of 275 mm, Y-axis stroke of +75/-75 mm, and Z-axis stroke of 370 mm. Rapid traverse speeds of 48 m/min for X-axis and 36 m/min for Z-axis.
Cooling System: 180-liter tank capacity with a pump pressure of 4.5 bar.
Dimensions and Weight: Machine weight ranges from 5600 kg to 6000 kg, with dimensions of 4400 x 2095 x 2675 mm.

Automation and Control: The machines are equipped with a Mitsubishi MELDAS 65S-L CNC unit, featuring an automation interface for increased productivity and management. A cutting load monitoring system is available for safe automatic machining.

Conclusion: The BV series offers a range of solutions for flexible automation and efficient production management, with options for linking machines and customizing loading/unloading operations to meet specific machining requirements.

The vertical moving spindleperforms both machining and automatic loading/unloading of parts. This solution allows a simple two-axis CNC-lathe tobecome an automatic machineto carry out unmanned machining operations.For loading and unloading ofparts, the standard BV confi- guration comprises a chain with location prisms for blanksand a simple conveyor forfinished parts. The loading sta-tion is equipped with a sprung platform to compensate anyirregularity of the blanks.Air blowers and cleaningdevices are provided to elimi-nate the swarf. >
