Rotary press processing is a commonly used manufacturing method, with a principle somewhat similar to “pottery art”. It involves fixing a flat blank or pre-formed blank onto a rotating mandrel, applying pressure to the blank with a rotating wheel, and simultaneously advancing the wheel axially. Through one or multiple processing steps, various thin-walled hollow rotary body products are obtained. This process can achieve multiple processing techniques, such as stretching, compression, bending, etc. Common products include pressure vessels, vacuum pumps, lamp covers, kitchenware, etc., most of which are manufactured through rotary press processing.
Rotary press parts are products manufactured through rotary press processing, and are generally made of metal. The Stack Robotics three-dimensional laser cutting machine is particularly suitable for the irregular cutting (cutting circles, cutting holes, cutting arc-shaped shapes, etc.) of such rotary press parts, stamping parts, stretching parts.

Frequently Asked Questions
What is the maximum workpiece size your three-dimensional fiber laser cutting machine can handle for rotary press components?
Our Intouchray 3D system accommodates rotary press parts up to 2,500 mm in diameter and 6,000 mm in length, with a maximum workpiece weight of 1,200 kg, ensuring compatibility with large drum cylinders and anilox rollers.
What cutting tolerances can I expect on complex 3D geometries like helical gears or perforated screens?
Typical positional accuracy is ±0.03 mm over the entire working envelope, with a repeatability of ±0.01 mm, allowing precise cutting of intricate patterns such as 0.5 mm diameter holes in hardened steel sleeves.
How does the machine handle varying material thicknesses common in rotary press tooling?
The system automatically adjusts focal position and power, cutting mild steel from 0.5 mm to 25 mm and stainless steel up to 20 mm, with a maximum cutting speed of 120 m/min on thin-gauge sheet.
What is the estimated return on investment (ROI) for integrating this machine into an existing rotary press production line?
Based on field data, users typically achieve a payback period of 14 months, with a 40% reduction in secondary finishing operations and a 25% increase in overall throughput for complex part runs.
Can the machine cut both flat sheets and pre-formed rotary press cylinders without re-fixturing?
Yes, the 6-axis robotic arm and rotary tilt table allow seamless switching between flat blanks (up to 3,000 x 1,500 mm) and cylindrical parts up to 1,500 mm in circumference, with a changeover time under 90 seconds.
What are the maintenance intervals and operating costs for the fiber laser source in this application?
The IPG fiber laser source requires scheduled maintenance every 20,000 operating hours, with a typical cost of €0.85 per hour for consumables and electricity, and a laser diode lifespan exceeding 100,000 hours.
