Máquina de ranhuras

Pipe slotting machines cut slots or grooves into round, square and rectangular tube so panels, shelves and cross-bars assemble without welding — the standard process behind shop-fitting racks, supermarket shelving, HVAC frames, school furniture and display systems. Slot size, speed and feed rate are set through the CNC system, and the operator can customize the required pattern per job.
The CTK-KC600 pipe slotting machine
The CTK-KC600 is a rotary-knife slotting machine built for continuous production. Published specifications:

Saw blade diameterφ140–600 mm
Max. tooth pitch18 mm
Max. saw blade thickness8 mm
Tube shapesRound, square, rectangular

Where slotting fits in your process
A typical tube fabrication line runs: tube cutting (laser or cold saw) → bending → slotting → welding or mechanical assembly → powder coating. Slotting after bending guarantees the slots line up with the bent geometry — which is why furniture and racking manufacturers slot the tube after forming.
Slotting vs. laser cutting for slots

Slotting machine — lower cost per part at high volumes, fast cycle times, ideal for repeating slot patterns on long tubes.
Fiber laser tube cutter — better for complex patterns, variable slot spacing, or combining cutting and slotting in one setup (see our laser tube cutting guide).

If you cut and slot the same tube on separate machines, a tube laser cutter with a rotary attachment can often replace both processes.
How to choose a slotting machine

Tube size range — match the clamping range to your largest tube section.
Slot width and pitch — blade diameter and tooth pitch determine the minimum slot.
Material and wall thickness — thicker walls need a stiffer frame and more power.
Volume — manual loading suits short runs; automatic feeding pays back quickly on batch work.
