Gruvmaster RG-4X Pro: Structural Updates Based on the RG-4X
Based on long-term use of the RG-4X, Gruvmaster introduced a series of structural refinements that led to the RG-4X Pro.
These updates do not add new functions. Instead, they focus on improving stability, durability, and details that become more apparent during extended operation.
Compared with the RG-4X, the RG-4X Pro shows its main differences in the following areas.
1. Frame Upgrade with Integrated Storage Box
The RG-4X Pro replaces the original support legs with an integrated frame that includes a built-in storage box.
This structural change improves overall machine stability while also providing practical space for commonly used tools and accessories on site.
In daily operation, this layout helps keep the working area more organized and reduces unnecessary handling.
2. Larger Grooving Assembly
The grooving assembly on the RG-4X Pro has been enlarged.
The increased size helps maintain more stable load distribution during grooving, contributing to improved durability and more consistent control of pipe-end flaring.
This adjustment is intended for applications involving higher operating frequency and heavier working conditions.
3. Reinforced and Thickened Pipe Support
On the RG-4X Pro, the pipe support structure has been fully reinforced and thickened.
This makes it better suited for long-term, continuous heavy-duty use and helps maintain stable pipe support throughout the grooving process.
When handling longer or heavier pipes, this structural improvement is more noticeable in practical operation.
4. Upgraded Positioning Rollers to Reduce Pipe Movement
Pipe movement during grooving is a common factor affecting process stability.
The RG-4X Pro uses reinforced positioning rollers to more effectively limit pipe deviation during operation.
This update does not change the basic operating method, but it helps reduce pipe movement and makes the grooving process easier to control.
Conclusion
Compared with the RG-4X, the updates to the Gruvmaster RG-4X Pro are concentrated at the structural level:
a more stable frame design, a more durable grooving assembly, stronger pipe support, and more reliable positioning.
These changes do not alter the fundamental working principle of the roll grooving machine. Rather, they reflect targeted adjustments based on repeated, practical requirements identified during long-term use.
