CDRG Threading Machine (Roll Threading Machine)
The CDRG Threading Machine is a solid and high-precision
rolling machine used for threading TMT rebars. It works using the Cold Rolling
Process, which forms continuous and accurate threads for bar-to-bar coupler
connections, increasing joint strength and reliability.
Key Features :
- Thread Type: ISO Metric / Unified / Custom as per client requirement
- Thread Angle: 75° / 60° (Standard for coupler systems)
- Threading Process: Cold Roll Threading, not cutting—preserves bar strength
- Roller Life: Long-lasting alloy rollers (up to 5000–6000 threads depending on use)
- Thread Length Capacity: Up to 100 mm (adjustable)
- Bar Size Capacity: 16 mm to 40 mm (depends on model)
- Motor Power: 5 HP – 3 Phase, 50 Hz
- Spindle Speed: Approx. 40–60 RPM
- Coolant System: Integrated for smooth operation and longer tool life
- Control Panel: With emergency stop and safety protections
- Mobility: Equipped with wheels for easy shifting on-site
Advantages :
- Preserves bar strength (no cutting involved)
- Fast threading in 20–30 seconds per bar
- Less maintenance required
- Compatible with IS 16172:2023 coupler standard
- Cost-effective for mass projects (high output)
