USED STANAT TA-400 6" X 6" 2-HIGH WEDGE ROLLING MILL

The Stanat TA-400 6" x 6" 2-High Rolling Mill is a heavy-duty, precision-built machine featuring a hydraulic wedge-style roll gap adjustment system, designed to maximize mill stiffness and minimize internal clearance.

Unlike traditional screwdown mills, this unit eliminates upper screwdowns entirely. The top roll assembly is fixed directly into the mill housing, while the bottom roll assembly is raised using a wedge mechanism, effectively taking up nearly all structural play within the mill. This design significantly improves rigidity, repeatability, and gauge control—making it particularly well-suited for precision rolling applications.

Hydraulic Wedge System – Important Note

This mill is designed with a hydraulic wedge adjustment system, however:
The hydraulic wedge assembly was not fully completed
All major components required to complete the system are included
Final assembly and control integration will be required to bring the wedge system into full operation

This presents an excellent opportunity for a buyer to complete and customize the system to their specific control and performance requirements.

Key Advantages of Wedge Adjustment Design
Exceptional rigidity by removing traditional screwdown backlash
Improved gauge consistency through bottom-up gap control
Reduced deflection under load due to tightened structural stack
Simplified mechanical interface with fewer wear components
Condition & Upgrade Potential

The mill is offered in as-is condition and currently does not include active electrical controls. It can be:
Placed into service with customer-supplied controls, or
Fully upgraded by IRM with modern drives, PLC/HMI controls, and hydraulic integration

Optional upgrades may include:
Complete hydraulic system integration for wedge control
Digital position feedback for roll gap
New electrical control panel and VFD system
Load cells and data acquisition
Roll regrinding or new roll sets
Updated guarding and safety systems
Overall

The Stanat TA-400 wedge-adjust design represents a more rigid alternative to traditional screwdown mills, making it an excellent candidate for precision rolling, R&D, or specialty production applications. With the hydraulic system components already in hand, this unit offers strong value for buyers looking to implement a high-stiffness rolling platform with customizable controls.
