The SUNTECHMACH CG-2X is an electric motor-driven groove cutting machine for cutting a groove on the pipe end (rather than rolling a groove) of 2" to 12" O.D. pipe with 6mm-35mm wall thickness, in all materials. It uses hydraulic fixing with manual blade feeding and a cut blade for precise grooving. The motor's built-in high-performance gear reduction system enables a compact, low-noise design, while the combination of the hydraulic feeding pump and a high-quality cutting blade guarantees premium grooves and optimal efficiency. An 8"-32" size is also optional.
THE PROBLEM
HOW WE SOLVED IT
Roll grooving is unsuitable for some thick/hard pipe
Cut grooving removes material for a precise groove on 6mm-35mm wall
Heavy pipe must be held firmly during grooving
Hydraulic fixing clamps the pipe securely
Groove depth must be accurate and repeatable
Manual blade feeding with stop nut for depth control
Job-site work is noisy
Built-in gear reduction for a compact, low-noise design
High-volume fabrication
Designed for heavy volume on job site and in-house workshop fabrication
Key Features
Cut Grooving — Cuts a groove on the pipe end instead of rolling it.
2"-12" Capacity — DN50-DN300 (Ø60-325mm), wall 6mm-35mm, all materials.
Cut the pipe square and square the end; remove burrs; grind weld bead/scale 6"/150mm back.
Support the pipe on pipe stands; 3m+ pipe needs at least two stands.
Turn the feeding hand wheel anticlockwise to lift the cut blade to top position.
Turn the pump relief valve to OPEN, locate the pipe on the drive roller and CLOSE the valve.
Press the pump lever 3-5 full strokes to secure the pipe with the pinch rollers.
Switch ON and confirm the pipe does not walk off; adjust stands if needed.
Feed the cut blade clockwise; 1/4 turn per pipe revolution ≈ 0.375mm (0.015") cut depth.
Keep lubricating the blade with cutting fluid to cool it — do not overfeed.
When the required depth is reached, tighten the stop nut and let the pipe turn 2 more revolutions.
Lift the blade, open the relief valve, remove the pipe and check with a groove tape.
Common Faults & Solutions
Common faults
Reasons
Solutions
Groove diameter wrong
Wrong cut blade / locating collar for pipe size
Fit the correct cut blade and locating collar
Pipe walks off the drive roller
Pipe not level / stands misaligned
Level the pipe and offset the stands 1°-2°
Blade wears quickly
Insufficient cutting fluid / overfeeding
Keep lubricating; reduce feed rate
Groove bottom rough / uneven
Overfeeding / blunt blade
Reduce feed; replace the cut blade
Blade hits pipe on loading
Blade not in top position
Always lift the blade to top position before loading
