According to the directory, positioning accuracy is typically ±0.001 to ±0.01 mm for linear axes, depending on feedback resolution and mechanical stiffness. This is based on ISO 230-2 test code. Always verify the actual accuracy for the specific model with the manufacturer.
Drive types include ball screw, linear motor, piezoelectric, and pneumatic systems. The selection depends on accuracy, speed, and load requirements. For example, piezoelectric drives offer high resolution but limited travel, while ball screws provide a balance of accuracy and load capacity.
Feedback systems include rotary encoders, linear scales, and laser interferometers. Closed-loop control is typical. Laser interferometers provide the highest accuracy but are more expensive. The choice depends on the required precision and budget.
The operating temperature range is 10–40 °C, humidity 5–95% non-condensing, vibration ≤0.5 g (5–500 Hz), and atmospheric pressure 86–106 kPa. Outside these ranges, lubricant degradation, thermal expansion, condensation, resonance, or reduced air pressure can cause loss of accuracy or failure. Verify the specific limits with the manufacturer.
