Frequently Asked Questions (FAQs) – Buying Used Mechanical Presses

At S&G Press & Machinery, we specialize in buying and selling high-quality used mechanical presses and stamping equipment. Whether you're a first-time buyer or an experienced manufacturer, we understand the importance of choosing the right press for your production needs. Below are answers to some of the most common questions about purchasing a used mechanical press.

1. What should I consider when buying a used mechanical press?

• Tonnage Capacity: Ensure the press tonnage meets your stamping and forming requirements.
• Bed Size & Stroke Length: The press should accommodate your tooling and production needs.
• Frame Type: Choose from gap frame (C-frame), straight-side, or knuckle-joint presses.
• Press Condition & Maintenance History: Check for structural integrity, lubrication, and component wear.
• Under Power Inspection: Always verify that the press runs smoothly before purchasing.
• Control System & Safety Features: Look for modern controls like Wintriss, Link, or Toledo.
• Availability of Spare Parts: Ensure replacement parts are accessible to minimize downtime.

2. How do I determine the right press tonnage for my application?

Tonnage requirements depend on material thickness, type, and forming process. A basic calculation is:

Tonnage = (Perimeter × Material Thickness × Shear Strength) / 2,000

Application-Specific Recommendations:

• Blanking & Piercing: Requires robust tonnage to handle reverse forces.
• Deep Drawing: Needs slow ram speed and full tonnage throughout the stroke.
• Bending & Forming: Depends on material thickness and bend angle.

3. What is the difference between a reconditioned and a rebuilt press?

Feature	Reconditioned Press	Rebuilt Press
Scope of Work	Minor repairs & updates	Full disassembly & restoration
Parts Replaced	Bearings, seals, lubrication	Pneumatics, hydraulics, electrical, controls
Performance	Improved functionality	Restored to factory specifications
Cost	Lower investment	Higher investment, longer lifespan
