CNC Tube Laser Dynamic Balancing & Chuck Runout Calibration (120 RPM)

When cutting slender tubes (length ≥6m, aspect ratio >100) at high rotational speeds (100–140 RPM), centrifugal force induces severe tube whipping and resonance, producing jagged wavy cut edges. This guide details ISO G2.5 dynamic balancing procedures and dual-dial gauge coaxial calibration for ACTCNC pneumatic rotary chucks.

1. Chuck Runout & Geometric Alignment Tolerances

Measurement Point	Inspection Instrument	ACTCNC Factory Standard	Impact on Cutting Precision
Front Chuck Radial Runout	Micron Dial Test Indicator	≤ 0.025 mm	Eliminates wall thickness offset & hole roundness error
Rear Chuck Axial Coaxiality	Dual Laser Alignment Collimator	≤ 0.030 mm (Full Stroke)	Prevents pipe twisting and clamping tooth binding
Dynamic Follow-up Roller Height	Optical Height Gauge	±0.05 mm (Servo Synced)	Absorbs gravity sag on 12m heavy structural pipes

2. Dynamic Servo Acceleration Compensation (TubesT Integration)

By coupling machine rotational inertia parameters with CNC acceleration feed-forward algorithms, rotational jitter is suppressed by over 80%, enabling pristine square tube corner rounding at 1.5G acceleration.
