Hydraulic-Driven Precision Grooving:

Mechanism: High-force hydraulic cylinder combined with a heavy-duty manual or electric hydraulic pump.

Function: Delivers smooth, progressive downward force on the upper grooving roll, cold-forming the pipe wall against the lower drive roll.

Benefit: Ensures uniform groove profiles and prevents pipe wall fracturing or deformation.

Standardised Groove Profile Control:

Mechanism: Precision depth adjustment gauge and micro-metric limit switch.

Function: Allows operators to pre-set the precise groove depth according to international piping standards (e.g., AWWA, ASTM).

Benefit: Guarantees consistency across hundreds of grooved joints, ensuring leak-free coupling fitment.

High-Torque Spindle Drive:

Mechanism: Low-RPM, high-torque industrial induction motor with a hardened steel gear reduction box.

Function: Drives the lower knurled shaft to rotate heavy steel pipes under high hydraulic pressure without slipping.

Benefit: Provides smooth rotation, reducing tool wear and ensuring concentric groove tracking.
