ER-Collet chuck BT 30 - 2/16 - 70 |ER 25Application: For mounting straight shank tools in collets. Delivery: With balanced clamping nut All holders are made of forged steel Specific, low warpage hardened Surface hardened HRC 58~60 Hardening depth 0,8mm~0,9mm Taper angle tolerance < AT 3 according to DIN 2080 Surface roughness Ra < 0,4 m Tensile strength in the core of min. 800 N mm after DIN All functional surfaces fine machined

In the tailstock of the lathe so that no friction between the workpiece and the tip occurs

Minimum internal diameter measurement capability of:

With 8mm stem diameter

bei Ø 6 – Ø 32 mm = h237

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance2

min-1) = 6000

it can be easily repaired at low cost

Measuring surfaces are precision ground for accuracy

For clamping nuts OZ-system

clamping depth = 41

The stylus has a predetermined breaking point at the very top

With coolant channels for optimal coolant at the cutting edge
