Band Saws – Technical Specifications and Innovations

SRR System (Permanent Magnet DC Motors with Inverter)

• Patented system combining DC motor with permanent magnets powered by 230V AC and inverter control.
• 60% noise reduction, lower heating, energy savings, robust mechanics with fewer gears.
• Brush replacement interval ~1500 hours (10x longer than typical).
• Cast iron pulleys allow spray lubricant use during cutting.
• Includes thermal and amperometric protections and electronic speed regulator to maintain constant speed and prevent overload.

Induction Motors

• Constant speed (~3000 rpm), maintenance-free, aluminum housing with heat dissipation fins.
• Available in single or dual-speed versions for intensive industrial use.

Band Saw Categories and Usage Recommendations

• Portable Band Saws: Lightweight, aluminum bow, high-performance motors with overload protection, Roentgen® M42 blades with cobalt for durability.
• Semi-Portable Band Saws: Aluminum or cast iron bases, induction or SRR motors, performance comparable to industrial saws.
• Stationary Industrial Band Saws: Heavy cast iron construction, blade tension ~210 N, cutting precision <0.03 mm/100 mm, designed for continuous industrial use.

Selection Guidelines

1. Choose portable/semi-portable models under 50 kg for mobility.
2. Select saw based on maximum cutting diameter and material; most support 60° angled cuts except TM101.
3. For intensive daily use (>2/3 hour), prefer induction motors; otherwise, SRR inverter motors are suitable.

Additional Features and Quality Assurance

• Powder-coated finishes, optimized base dimensions, precise blade lowering geometry.
• Integrated "Zero Dust" extraction system and compatibility with spray lubricants enhance safety and blade life.
• Quality packaging ensures optimal delivery condition.
