B620

The new B620 represents the “state of the art” of multifunction turning centers. The modular concept and the high versatile options provide a wide spectrum of machining possibilities ranging from universal turning to complete machining of complex parts thanks to the CNC automatic tailstock, second spindle, rotary tools, spindle C-axis and Y-axis. The B620 is available in five versions with bar capacity of 51 or 80 mm.

Bar capacity

At the heart of the new BMX51/70 turret is a powerful integrated motor in the tool disc, thermally cooled and stabilized for maximum efficiency.
The motion is transmitted directly, with no kinematic chain: the motor is directly coupled to the tool holder.
The result? A simpler, more compact, high-performance system.
Main advantages:
- Drastically reduced vibrations
- No power loss or mechanical play
- Less heat generation
The final benefit is tangible: better finishes, greater rigidity and removal capacity, with quieter and more stable operation even during the toughest processes.

Turret with Integrated Motor: Power and Precision at the Core

B620

The new liquid cooled integral motor spindles are driven by high-torque motors with unequalled power.
They allow higher spindle speed.
Also, the combination of the roller and ball bearings, plus the high torque and constant horsepower range, allow powerful cutting as well as exceptional finish and roundness accuracy.

Integral Motor Spindle

ASA -5

ASA -6

ASA -8

The tailstock body is operated by a servo motor and baIlscrew (B-axis).
This solution improves operating flexibility since position and thrust are CNC-controlled.
It can also be used to perform simultaneously both drilling and turning

CNC Automatic Tailstock

B620

Complete machining in one set-up, spindle synchronisation sub-spindle load monitoring when the workpiece is transferred from the main to the sub-spindle.
Simultaneous machining Thanks to this option, two tools can work simultaneously on both spindles.
Cycle time is drastically reduced.

SUB-Spindle with C-Axis:

Prepared to accept automation

Interface for bar loader

Interface for gantry loader for automatic loading

ROTARY TOOLS, C-AXIS, Y-AXIS AND SUB-SPINDLE:

Complete machining in one set-up

Flat milling in repeated cuts

Irregular slot milling (roughness-finishing)

Key-way milling

Thread milling

Drilling and milling grid holes

POLYGON TURNING

This optional feature allows to turn polygons and threads provided the suitable driven tools are used.
The gear hobbing tool allows machining of gears.

PARTS-CATCHER

Two styles of automatic parts-catcher systems are available on the B620:

1) The common parts-catcher arm system with parts bucket that allows the unloading of finished parts on to a parts conveyor. (unloading from the main and the sub-spindle)
2) The new parts-catcher arm system that takes the finished part from the sub-spindle and unloads it directly on to a secondary parts conveyor (unloading through the sub-spindlle only).

Unloading sequence of the parts-catcher arm on the sub-spindle:
– Pick-up of finished part
– Unloading on to the primary parts conveyor
– Collection of finished part on to the secondary parts conveyor
