AG-8Z 2"–12" Automatic Grooving Machine
AG-8Z is a new-generation compact automatic roll grooving machine for consistent grooving quality even under continuous high-load working conditions. It uses Gruv-X hydraulic technology with a dual-seal system that reduces oil leakage risk and helps maintain stable oil temperature during continuous operation. The roll groover supports efficient grooving at up to 32 RPM and can be controlled by either foot switch or remote control for flexible operation.

-
- The Gruv-X hydraulic system is designed for continuous high-load operation.
- A dual sealing structure helps reduce leakage risk, and under normal working conditions, hydraulic oil replacement can reach 2–3 years, reducing downtime and maintenance cost.
Heavy-Duty Hydraulic System -
- The adjustment screw includes a clear scale for direct groove depth control.
- It supports repeat positioning, helping reduce manual error and maintain consistent dimensions in batch production.
Visual Depth Adjustment -
- It uses a full physical button control system with direct response and strong anti-interference performance, suitable for industrial environments.
- An integrated pressure gauge allows real-time pressure monitoring during operation.
Physical Button Control System -
- High-strength drive and grooving rollers provide stable contact and reliable transmission.
- Groove formation remains consistent during continuous operation, supporting stable output quality.
High-Strength Grooving Structure -
Remote Control OperationThe grooving machine supports switching between wireless remote control and manual operation for flexible use in different working conditions.
-
- Compact structure with balanced weight distribution helps reduce vibration and movement during operation.
- Equipped with a telescopic handle and wheels for easy single-person transport and on-site movement.
Compact Structure & Mobility Design -
Core ComponentsKey electrical and hydraulic components use internationally recognized brands for stable performance. The system maintains reliable operation under high-frequency use and reduces failure and maintenance requirements.
-
- Includes hex keys, depth gauge, and other common tools for on-site adjustment.
- A non-slip top pad provides a temporary tool placement area for convenient access during operation.
