BROWN SN 420 SA Semi-automatic saw

The semi-automatic band saw IBP PEDRAZZOLI BROWN SN 420 SA features all main machine components in cast iron. The very robust structure reduces resonance and vibrations during cutting cycle.

FEATURES

• 2 Speed Three-phase (V 400 – 50 Hz) other voltages upon request.
• Motor is in vertical position to reduce dimensions at rear, the transmission is made by means of a worm drive gearbox in oil bath (1:40 ratio).
• Large circular support base: it offers an ample surface to support piece during cutting cycle and allows to reach a high grade of precision in cutting perpendicularity. It rotates over a tempered ball track giving maximum smoothness during rotation.
• Adjustable bow position by means of a key on eccentric bushing for 90° cuts, by means of mechanical stops at 45° right & 45°-60° left.
• Blade guides: they drive the blade sliding by means of widia hard metal plaques with bearings on eccentric bushings.
• Hydraulic cylinder for adjustable vice motion. It can be positioned lengthwise along the entire machine base. Vice features: rapid closing, closing hand wheel, flat adjustable gib plate.
• Retractable and adjustable vice shoulders. Pushing back the retractable vice shoulder, it is possible to reach the maximum cutting capacity (420 x 190 mm, at 90°). The adjustable vice shoulder allows to obtain a precise alignment at all times.
• Blade tightening device: this is the best solution for a constant and uniform blade tension.
• Blade lubrication cooling system with electric pump and two adjustable taps placed on blade guides.
• Control panel located in an easily accessible position with ON/OFF switch, cutting speed selector (2 speeds), MANUAL/ DYNAMIC cutting selector (for machines with Newton device), emergency push button to cut off the power to the motor in case of emergency.
• Blade start switch with “man present” guard. This is for starting blade rotation during manual cutting cycle; it is guarded by a cover against accidental start-up. It works in low voltage.
• Drive pedal for semiautomatic cutting cycle.
• The hinged bow is moved on a support with conical bearings.
• Double emergency push button located in front of the machine frame for greater security in case of need.
• Electronic safety sensor to stop blade motion in case of slipping or breakage of the same.

CONTROL PANEL FOR SA-IDR SAWS

PLC control panel specifically developed for band saws by IBP PEDRAZZOLI: it can be programmed by the operator according to the machine use requirements.

• The machine can work in manual or semiautomatic mode. ON/OFF switch
• Digital display
• Programmable piece counter
• Blade rotation speed
• Lubrication mode selector
• Manual or semiautomatic cycle selection
• Advanced functions (vice opening/closing at the end of cutting – ON/ OFF blade rotation at the end of cutting – etc…)
• Ampere absorption display (for cutting speed control, blade wear, etc…) and instant blade speed.
• Semiautomatic cycle stop (pressing this key causes the bow to go up & the vice stays closed)
• Flow regulator, for adjustment of bow descent speed
