The Art and Science of Industrial Cutting

Cutting is one of the most fundamental operations in manufacturing. Whether you're producing automotive body panels, HVAC ductwork, electrical enclosures, or signage — the quality of the cut determines the quality of everything that follows. A poor cut means rework, waste, and customer complaints. A perfect cut means efficiency, precision, and competitive advantage.

At Grossmann, we've been engineering cutting solutions for decades. Our machines don't just cut — they cut with the precision, speed, and reliability that modern manufacturing demands.

Our Cutting Systems Portfolio

Plate and Sign Shears

Our Plate/Sign Shear is built for heavy-duty cutting of flat sheet material. Designed with a massive steel frame and precision-ground cutting blades, this machine handles:

  • Mild steel up to 20mm thickness
  • Stainless steel up to 12mm thickness
  • Aluminum up to 25mm thickness
  • Cutting widths from 1,000mm to 6,000mm

The blade gap is adjustable to 0.01mm precision, ensuring clean, burr-free cuts regardless of material type. The hydraulic system delivers consistent cutting force across the entire blade length — no more uneven cuts at the edges.

Blank Cutting Lines

For high-volume production, our Blank Cutting Line integrates decoiling, straightening, measuring, and cutting into a single automated system. Feed a coil of steel in one end, and precision-cut blanks come out the other — ready for stamping, bending, or welding.

Key specifications of our Blank Cutting Lines:

Parameter Specification
Material thickness 0.5mm to 8mm
Coil weight capacity Up to 25 tonnes
Cutting speed Up to 60 cuts per minute
Length accuracy +/- 0.1mm
Cutting width Up to 2,000mm

Hydraulic Presses

Complementing our cutting systems, our Hydraulic Presses handle forming, stamping, drawing, and embossing operations. Available in capacities from 50 tonnes to 500 tonnes, these presses feature servo-hydraulic drives for precise speed and force control throughout the entire stroke.

Engineering Excellence in Every Detail

What sets Grossmann cutting machines apart isn't just raw performance — it's the attention to detail in every aspect of the design:

  • Blade metallurgy — We use premium tool steel (DIN 1.2379 / AISI D2) for our cutting blades, heat-treated to 60-62 HRC for maximum edge retention. Each blade is precision-ground to a surface finish of Ra 0.4 micrometers
  • Frame rigidity — Our machine frames are stress-relieved after welding and precision-machined on large-format CNC boring mills. Zero flex means zero deviation in cut quality
  • Safety systems — Light curtains, two-hand controls, emergency stops, and hydraulic holding valves ensure operator safety. All machines comply with EN 13985 (guillotine shears) and the Machinery Directive 2006/42/EC
  • Automation readiness — Every machine includes interfaces for PLC integration, allowing seamless connection to upstream and downstream equipment

The Grossmann Advantage: Custom Engineering

No two factories are the same, and no two production challenges are identical. That's why a significant part of our business is custom machine building. Our engineering team works directly with customers to design and build machines tailored to their specific requirements.

Recent custom projects include:

  • A 4-meter wide plate shear with integrated CNC backgauge for an automotive supplier in Stuttgart
  • A dual-line blank cutting system with automated stacking for a white goods manufacturer in Turkey
  • A high-speed sandwich panel cutting line for a construction materials company in Nigeria

"Every machine we build carries our name. That's why we never compromise on engineering quality — whether it's a standard product or a one-of-a-kind custom solution."

Service and Support: We're There When You Need Us

A machine is only as good as the support behind it. Grossmann provides comprehensive after-sales service including spare parts supply (typically shipped within 24 hours for standard parts), remote diagnostics via secure VPN connections, on-site commissioning and training, and preventive maintenance programs.

Our spare parts inventory covers all machines we've built in the last 30 years. Even if your Grossmann machine is decades old, we can keep it running at peak performance.
