ER-Collet chuck HSK 63 - 3/26 - 130 | ER 40Application: 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

Heat-treated steel

Quick change adaptors without safety clutch can be interchanged

clamping depth 2 mm

- for easy determination of the reference point on CNC and conventional machines

Chrome vanadium steel main body

Collets sealed with seal for IC

M6 - M12 = 10

so the system is suitable for through-coolant feed

For measuring the groove diameter of shafts

Minimal length compensation on compression and expansion balances very small pitch differences between synchro spindle and tap

right angularity: 0

Wherever reduced interference contours are required
