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 70 mm.

DESIGNED TO ENSURE HIGH RIGIDITY AND ACCURACY
The new massive rigid cast-iron machine bed has been reinforced by 20% in comparison to the previous design. The roller guideways on the Z-axis and the “box type” guideways on the X and Y axes ensure high rigidity, speed and exceptional vibration dampening.

NEW BIGLIA SERVO-TURRET
Fast and rigid BIGLIA 15-station servo-turret. Live tooling on all positions. Up to 30 tools can be used together. The rotary tools are driven by a liquid cooled, synchronous built-in motor with 13 kW power and speed range of 6000 rpm. The rotary motion is transmitted by a built-in motor, lubricated and cooled by oil mist.

INTEGRAL MOTOR SPINDLESThe 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.

TOOL-SETTER
This device makes tool-setting simple, fast and accurate. The tool tip is brought into contact with the probe and the tool offset value is automatically stored into relevant table of the CNC control.
PARTS-EJECTOR
The sub-spindle is equipped with a parts-ejector featuring collet cleaning system and sensor to detect that the finished part has been ejected.
CNC AUTOMATIC TAILSTOCK
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.

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 armon the sub-spindle:- Pick-up of finished part- Unloading on to the primary parts conveyor- Collection of finished part on to the secondary parts

MANUAL GUIDE: QUICK AND EASY FOR PROGRAM RELIABILITY
The innovative MANUAL GUIDE software package provides operators with access to a very simple and user-friendly graphics interface, strong “editing” functions and offers a wide selection of machining cycles (turning, milling and drilling). This system allows the execution of even the most complex programs with ease of operation. The 3D simulation facilitates the checking of programmes before machining operations (option).
INTUITIVE AND EXTREMELY USER-FRIENDLY
The i-HMI is the new human-machine interface, 15” colour display with touch screen. The brand-new i-HMI system offers a high performance operating area where a simple touch allows the operator to gain access to all CNC functions: from work planning to BIGLIA customised pages, real time display of machining conditions and records of specific technical documentation.
DATA DISPLAY
Data displayed while machining includes: actual position of axes, machining feedrates, information on the spindle speed and current absorption, modal G-codes and machining cycle: all this on one screen page and in real time.

QUICK DATA VIEW
This option can be used with digital documentation in the appropriate folder. Tailstock set-up, BIGLIA customised tool life management, SBS tool load monitoring system, CSS spindle rpm variation – all in a simple and interactive mode.
SBS: TOOL LOAD MONITORING (Option) This system monitors the loading of the most heavily used tools such as cutting tools, roughening tools, drills or U-drills. It ensures safe automatic machining with limited operator presence (option).
CSS: SPINDLE RPM VARIATION (Option)
This option allows you to change the spindle rpm to eliminate resonance and vibration problems during embossing machining of parts.
USER-FRENDLY – EASY TO SET-UP Easy dialogue and set-up in connection with all the main machine features such as the parts-catcher with basculating arm, the B-axis tailstock and the tailstock to drill.
ANGULAR DISPLACEMENT For machines equipped with a sub-spindle this enables fast auto setting of the angular displacement for machining polygon bars.
NEW OPERATOR PANEL Using a simple touch, the new panel allows the operator to select, enable and disable all main functions during set-up operations.The green and red colours facilitate an immediate and fast reaction which results in reduced set-up times and cost saving.
