Clamp Force Meter/Mandrels

 

Measures the drawbar’s clamping force inside VMC/CNC/HMC spindles to ensure optimal tool-holding performance.

Clamp Force Meter

Features:

  1. Digital or analog readouts

  2. Compatible with various spindle types (BT, HSK, ISO)

  3. Precision load cells for accurate force measurement

  4. Compact and portable design

  5. Calibration is available for traceability

Benefits:

  1. Detects weak or failing drawbars

  2. Prevents tool slippage and machining errors

  3. Reduces the risk of spindle damage and downtime

  4. Essential for preventive maintenance

Mandrels

Mandrels (also known as spindle test bars or taper mandrels) are used to check spindle alignment, runout, and performance under various conditions.

Features:

  1. Made from hardened, ground steel

  2. Tapered to exact standards (BT,  HSK, ISO, etc.)

  3. Available in standard and customized lengths

  4. High concentricity and minimal runout
