• MPE_E (Maximum Permissible Error for Length Measurement): Written as an equation, such as 1.4 + L/350 μm or 1.7 + 3L/1000 μm. “L” represents the measurement length in millimeters. As the length increases, the allowable error margin grows slightly. 
• MPE_P (Maximum Permissible Probing Error): The error threshold for a single point measurement, often sitting around 1.3 μm – 1.5 μm. 
• Repeatability: The machine’s consistency when measuring the exact same point multiple times, typically requiring a deviation of less than 1.0 μm. 

• X-Axis (Width): Standard sizes span 500 mm to 2,000 mm.
• Y-Axis (Length): Scales anywhere from 400 mm to 4,000+ mm.
• Z-Axis (Height): Vertically limits parts from 400 mm to 1,600 mm. 

• 3D Driving Speed: High-efficiency CNC machines feature drive speeds up to 400 mm/s to 693 mm/s.
• 3D Acceleration: Dictates how fast the probe moves between points, ranging from 700 mm/s² up to 2,309 mm/s².
• Workpiece Weight Capacity: Smaller shop-floor models hold up to 180 kg, while heavy-duty industrial gantries support over 5,000 kg. 

• Standard Temperature Range: Most accurate environments require a stable temperature between 16°C and 26°C.
• Thermal Variations: High-end models require a variance limit of less than 5°C per 24 hours, using built sensors on the axes to correct calculations in real time.

• Table Stage: Constructed out of high-grade Granite to provide structural rigidity, natural vibration damping, and low thermal expansion.
• Axis Construction: Built using Ceramic, Granite, or high-tensile Aluminum alloy to reduce moving weight while avoiding deformation.
• Bearings: High-precision machines completely isolate axis friction by utilizing Air Bearings across all three axes. 

• Touch-Trigger Probes: Capture discrete, single physical contact points.
• Analog Scanning Probes: Drags continuous physical contact across complex curves for complex geometric profiling.
• Non-Contact Sensor Options: Laser scanners, optical cameras, and white-light sensors for fast point-cloud generation on flexible or delicate materials
