Motion system on the basis of linear drive
- Maximum acceleration
- Wear-resistant, without conversion of rotational energy into linear form
- Maximum precision and quality, no backlashes even over time
The entire ARAMIS products range uses powerful drives based on synchronous collectorless linear motors of the company’s own design. The moving parts’ interaction is performed by the magnetic field. Such drive guarantees high precision, dynamics and speed of motion, makes backlashes impossible. Application of this technical solution in our machines allows to increase their productivity many times over, as well as to achieve high cutting precision, which does not deteriorate over the years of operation.
Comparison of motion systems
Comparative characterization Ball-and-screw unit |
Rack and pinion drive |
Linear motor |
|---|---|---|
| Prone to wear and loss of precision due to the large number of closely interacting parts. | Subject to wear and loss of precision due to high mechanical loads’ impact | No wear and tear. Electromagnetic interaction only |
| Presence of backlashes that affect precision | Backlashes that adversely affect precision | No backlashes |
| Loss of precision on long motion strokes | Loss of precision on long motion strokes | High precision on any kinds of motion strokes |
| Poor dynamics. The ball-and-screw does not provide high motion speeds. Operating at higher speeds results in significant additional wear. | Quite high motion dynamics. Operating at higher speeds results in significant additional wear. | High motion dynamics. More frequently, the cutting tool technologically impedes utilizing the drive dynamics fully. Working at higher speeds does not result in additional wear |
| Low reliability as a result of ball-and-screw unit design features | Low reliability as a result of highly dynamic mechanical interaction | High reliability due to the absence of parts prone to wear out |
