Automatic Cutting of Forged Rings | RINGSAW

USA | Industrial and Aerospace

Project Overview

Client: Leading U.S.-based company specializing in forged rings for industrial and aerospace applications

Year: 2024

Technology: RINGSAW | Dual vertical cutting unit system with rotating arm and spindle

Location: USA

 

Industry: Industrial and Aerospace

The Challenge

A well-established American forging company needed to automate the high-precision cutting of
forged rings, with the following objectives:

  • Minimize material waste
  • Increase productivity without compromising quality
  • Cut sub-rings to exact dimensions, ready for further machining
  • Fully eliminate operator intervention during the cutting cycle

The customer was working with thin-walled rings and tight tolerances, intended for critical sectors such as aerospace and energy.

The Solution

Friggi supplied the RINGSAW system, custom-engineered to meet these specific requirements.
The machine is equipped with:

  • A rotating arm for automatic loading of the raw ring and unloading of finished sub-rings
  • A rotating spindle to securely lock the ring during the cycle
  • Two high-speed bandsaws, cutting simultaneously from both sides
  • A fully automatic process, with no manual repositioning required
  • Minimal tool kerf, just 3 mm per cut

Processed dimensions:

  • Outer Ø: 1610 mm
  • Inner Ø: 1470 mm
  • Ring thickness: 20 mm

Productivity & Efficiency

  • 2 rings cut every 30 minutes → 4 rings/hour
  • 32 rings per 8-hour shift
  • The system allows the recovery of up to 4 additional rings per shift, thanks to optimized cycles and reduced waste

The Results

The implementation of the RINGSAW system was delivered:

  • Continuous and stable production with repeatable quality
  • Significant material savings and reduced tooling costs
  • Elimination of operator risk, thanks to full automation
  • ROI in less than 12 months, due to increased productivity and process efficiency

The client successfully integrated the RINGSAW into their production flow, gaining a system
capable of handling high volumes with precision, safety, and consistency
