Height of neutral plane above Worktable : 20mm (0.79in)6. Roundness Limit of Error : Concentric Load 20kg (44.1 lb)(Departure from the least within 0.06 µm 0.0003µm/mmSquares circle at 6 rpm with height above worktable 0-50 u.p.r filter) (1.5 µin 0.3 µin/in)*7. Axial Error : 0.15µm (3.9 µin) maximum axial movement of worktable during one revolution. *These departures may be inwards and outwards C. VERTICAL STRAIGHTNESS UNIT 1. Measurement Length : 300 mm (11.8in),2. Accuracy of stop Measurement : 0.5mm (0.02in)3. Speed of Traverse (for set-up) : (1) Joystick slow speed0-3mm/s (0-0.12 in/s) for approx 70% of joystick travel. (2) Computer controlled <3 mm/sec variable.4. Straightness limit of Error : In the measuring plane: (Minimum zone straightness at 1µm over 300 mm (40µin 1mm/sec (0.04 in/sec) with over 11.8in) 8.0mm (0.3in) cut off low pass filter5. Positional Control Uncertainty : ±100µm (±0.004in) for one single move.6. Internal Capacity : 150mm (5.9in) For Straightness Limiting conditions, Maximum length of continuous Minimum diameter clearance Internal surface that can be assessed 115mm (4.5in) depth in bores larger thanØ25mm (Ø1in)7. For Roundness assessment Internal bore penetration : 150mm (5.9in), 115mm depth in bore of Ø25mm ***Internal penetration for other than ‘limiting condition’ depends on component geometry. D.
