From Hydraulic to Servo: The Evolution of the Punch Press
For years, hydraulic punch press machines were the main choice for metal work. They were strong and reliable but had some big downsides:
- High energy consumption
- Frequent maintenance due to fluid systems
- Inconsistent precision at high speeds
- Environmental concerns from hydraulic fluids
Servo-electric CNC punch press machines are a big step up. ACCURL’s electro servo tech brings together top-notch engineering and energy saving. This gives makers the edge they need today.
What Makes the ACCURL Electro Servo Punch Press Different?
ACCURL is known for its top-notch sheet metal machines. Their electro servo turret punch press shows their engineering skill. Here are some key features that make it stand out.
1. Next-Gen Servo Drive System
ACCURL’s innovation is in its REXROTH servo drive system. It replaces old hydraulic systems with a direct motor drive. This brings:
- Unmatched accuracy: Positioning accuracy of ±0.10 mm
- Energy savings: Uses only 50–60% of hydraulic machines’ power
- Low noise levels: Perfect for places where noise is a problem
- Instant torque: More responsive than hydraulic systems
2. Flexible Turret Design
The ACCURL punch press has various turret setups:
- 32 stations with 2 auto-indexing stations
- 36 stations with flexible index options
- Up to 42 stations with 4 auto-indexing heads
The turret design makes tool changes quick, job setups flexible, and lasts long. It works with standard punch press tooling brands like Wilson, Mate, and Trumpf.
3. Integrated Forming and Tapping
ACCURL’s electro servo system lets you do forming like:
- Louvers
- Embossing
- Tapping
- Countersinking
This means you don’t need extra steps, saving time and making production better. It also has variable dwell control for cleaner, more precise forms.
4. Stable O-Type Frame Construction
The O-type frame is better than C-frames for rigidity and less deflection. This means:
- Better tool alignment
- Greater punching precision
- Longer machine lifespan
The machine’s frame is made from thick, high-grade steel. This stops it from twisting or bending during punching.
5. Smart Sheet Handling System
With features like:
- Brush tables to reduce noise and prevent scratching
- Ball transfer tables for easy sheet movement
- Work chutes for automatic parts removal
- Optional stacking and sorting systems
ACCURL enhances productivity and keeps operations smooth and ergonomic.

Advantages Over Hydraulic Punch Press Machines
✅ Energy Efficiency
Servo motors only use power when needed, resulting in massive energy savings compared to hydraulic models, which often run continuously.
✅ Lower Maintenance
With no oil, filters, or pumps, maintenance is minimal. This translates to lower operating costs and higher machine uptime.
✅ Superior Precision
The ACCURL CNC punch press ensures consistent high-speed accuracy, making it ideal for industries that require tight tolerances.
✅ Environmentally Friendly
No hydraulic oil means no risk of leaks, spills, or contamination — a major plus for companies pursuing sustainability initiatives.
Applications Across Industries
The ACCURL Electro Servo CNC Punch Press Machine is ideal for a variety of industries:
- Automotive – Precision body panels, brackets, and components
- HVAC – Air ducts, grilles, and vent components
- Electrical enclosures – Cabinets, junction boxes, control panels
- Furniture – Frames, drawers, and shelving units
- Construction – Metal panels, brackets, and supports
Its flexibility allows it to process mild steel, stainless steel, aluminum, and galvanized steel effortlessly.
