Product overview
The manual band saw BROWN SN 420 IBP PEDRAZZOLI features main machine components in cast iron to reduce resonance and vibration during cutting operations. The machine is designed for metal cutting with adjustable bow position and a large circular support base for high perpendicularity accuracy.

FEATURES

• 2-speed three-phase (V 400 – 50 Hz; other voltages available on request)
• Vertical motor position to reduce rear footprint; transmission via worm drive gearbox in oil bath (ratio 1:40)
• Large circular support base with wide workpiece surface; rotates on a tempered ball track for smooth rotation and precise perpendicularity
• Adjustable bow position with eccentric bushing for 90° cuts and mechanical stops at 45° right and 45°/60° left
• Blade guides with widia (hard metal) plates and bearing supports on eccentric bushings
• Adjustable manual vice with rapid closing, handwheel and flat adjustable gib plate; positionable along the entire machine base
• Retractable and adjustable vice shoulders to reach maximum cutting capacity (420 x 190 mm at 90°) and ensure precise alignment
• Blade tightening device for constant and uniform blade tension
• Blade lubrication/cooling system with electric pump and two adjustable taps on the blade guides
• Control panel in an easily accessible position with ON/OFF switch, cutting speed selector (2 speeds), MANUAL/DYNAMIC cutting selector (for versions with Newton device), and emergency push button
• Blade start switch with "man present" guard and safety cover; low-voltage operation
• Hinged bow moved on a support with conical bearings

Advantages

• Widia blade guides for durable guidance
• Vice with quick approach, transversally positionable along the machine base; adjustable vice shoulders
• Loading & unloading conveyor (available on request)
• Digital display (available on request)
