ER-Precision collet chuck BT 40 - 2/20 - 70 | ER 32Application: For mounting straight shank tools in 2 m collets. Advantage: Excellent concentricity in the system (chuck + collet + clamping nut) 3 m radial run out with a 2 m clamping nut, 6 m radial run out with a 5 m clamping nut Extremely strong holding force (increases the holding power by at least 60% compared to standard ER chuck) Plain clamping nut without grooves for high speed machining

E3= 20 pieces

For the inspection of machine tools according to ISO ­recommendation R230 or for testing the tool spindle

Upon switching on the display will read the actual absolute measuring position

The fine-adjustment allows the slider to be precisely positioned

quick and simple measuring of the clamping force of hydraulic chucks

Internal measurement jaws are rounded to provide accurate measurement of internal diameters

20mm for over 500mm/20" range

Spherical end anvil

Capacity = 1 - 10 (ER 16)

In this way the clamping ranges can be extended to smaller sizes

Accuracy: ±5 min
