Grupo Plasma Automation consists eight companies that specialise within the design and manufacture associated with fabrication automation. The collection produces a broad variety of plasma, laser and also water jet cutting machines. Founded in 1991, GPA has grown steadily over time and has built up a considerable and prestigious customer put faitth on; it has more as compared to 700 cutting systems installed at companies in Mexico on your own, and nowadays serves both domestic and international economies.
GPA’s latest CNC laser cutting machine was designed to provide sheet metal fabricators with an ultra-flexible precision slicing solution. Branded SPEED STRUCTURE, the machine is capable of cutting a wide variety of metals with different densities, as well as galvanised iron, aluminium, brass, stainless plus carbon steel. It is known for a work area of ONE PARTICULAR. 5 x 3 metres along with a maximum cutting speed associated with 120 metres per tiny, with 40 microns positioning accuracy. The system generates extremely smooth operation sometimes at high speeds.

To aid maximise performance and stability, GPA’s new cutting machine located entirely on industry-leading laser plus control technology. The laser source is often a 2 kW IPG Photonics’ solid-state ytterbium fibre process, with a wavelength regarding 1. 07 micrometres, as the cutting head is your Precitec LightCutter 2. 0 unit. This particular cutting head is renowned to its dynamic performance – this features automated motor-driven adjustment of the axial focus position, can handle acceleration rates as high as 3g, and covers a sizable focus position range with 23mm.

All cutting head positioning functions on the machine are controlled by a NUM Flexium+ 8 CNC procedure. According to Omar Sandoval, User and CEO of GPA, “We chose to companion with NUM mainly because of its open architecture CNC platform and NUM’s willingness to actively participate in joint development projects such as this. ”

All four equipment axes are driven by NUM high torque BPX servomotors manipulated by NUMDrive X electronic digital servo drives; the Y1 and Y2 gantry axes are pre-loaded with powerful 9. 8 Nm motors, while the X in addition to Z axes have small 2. 7 Nm as well as 1. 4 Nm magnetic generators, respectively. NUM’s Flexium Tool commissioning computer software allows the Y1/Y2 axes that they are tuned while the synchronisation is definitely active, which provides a very powerful means of maximising operation and precision.

The Z axis settings the vertical height of the laser cutting head over the sheet of metal that's being cut. By capitalising about the unique ‘Dynamic Operator’ (DO) perform in NUM’s Flexium program – which enables event-driven machine cycles for being integrated into the real-time CNC kernel – the user of the speed slice machine benefits from a good automated dynamic height deal with system that accommodates extremely fast cutting speeds. The system interprets data in the machine’s cutting head length sensor and uses it to before long adjust proportional-integral-derivative (PID) loop parameters inside Z axis servo. The height sensor is likewise employed to facilitate a automatic sheet detection workout: this determines the workpiece’s proportions, zero, and angular countered, further simplifying the machine’s operation.

Steven Schilling, Managing Director of NUM Corporation around Naperville, Illinois, points away, “We are delighted being collaborating with GPA in the development of this new machine. In addition to the real-time adaptive height control and sheet detection devices, the customised version of NUMcut software that individuals are providing features some sort of user library of materials cutting conditions. It is preloaded by GPA using the optimal laser power degrees, cutting speeds, etc.,being a function of material variety and thickness. The provision of this library will further enhance the machine’s.
