COMPRESSION SPRING MANUFACTURING: HOW SMALL SIZES MANUFACTURING LINE IS MADE.
Here we are in the heart of our factory’s production area. Here is located the manufacturing integrated line for small size compression springs and their relative quality control.
Let’s see together which units it is composed of and what are the features that guarantee high precision and reliability of the product.
Coiling: Simplex Rapid FX10
Simplex Rapid FX10 is a high-speed automatic coiling machine, equipped with a latest generation Multi-axis Numerical Control; suited for a specific production of compression springs, those with right-hand helix with even very complex variations in shape and pitch.
Performance and reliability
Performance and reliability of this machine are assured by the maximum simplification and the reduction of the number of mechanical parts, which therefore lead to less wear and inertia. The high-performance programming software, perfectly integrated with the hardware, allows direct control of all tools.
Among the most important features of the machine we can find:
- Motion Control Technology;
- High resolution digital transducers;
- Production control via video camera and backlight (SPC);
- Programming in microns;
- Extremely advanced and innovative software (SPG / SGP);
- Industrial PC with color touch screen;
- Integrated UPS unit.
Shot peening: Norblast TAP
The Norblast TAP automatic shot peening machine is equipped with adjustable shooting system in pressure / depression, ideal for mass treatment of small springs. All the operations of abrasive selection and recovery take place automatically through a suitably sized cycloning system: it conveys crushed grit and waste dust to the filter
The machine is equipped with a PLC panel for management of shot peening recipes management and scheduled maintenance activities.
Dimensional and surface measurements: Keyence VHX-7000 microscope
The Keyence VHX-700 is used to carry out dimensional and surface measurements. It is a 4K optical microscope, extremely easy to use even for beginner users: it allows the acquisition of images similar to those of a scanning electron microscope.
Vision and measurement
The microscope, equipped with a focus depth 20 times greater than traditional optical microscopes, is able to carry out 2D and 3D measurements: suitable both for dimensional checks and for analyzing roughness, contamination and other parameters with a single and effective instrument.
Lifespan test: Microstudio PMF-300
For fatigue tests, our laboratory is equipped with two Microstudio PMF-300 very useful for tests on small dimensions compression and traction springs.
These machines combine the characteristics of a high speed press with a brushless motor, allowing to perform the lifetime tests on 12 springs contemporary, with continuous verification of the integrity of each single piece by electrical contact.
