Boring bar holder - form E2 E2 - 25 x 25

Boring bar holder - form E2 E2 - 25 x 25Application: For internal machining with boring bars. 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

Clamping screw

With fi ne adjustment carriage to feed the slider finely

- Setting the rotary table zero point of 5-axis machining centres

Mirror polished surfaces

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

Only nominal size d can be clamped with sealing plug for internal cooling (applicable up to 21 bar) In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet

With high precision coolant you get improved

Zero-setting at any position

Individual serial numbers on each block

In this way

For mounting the coolant tubes in PSK toolholders

Extension rod >6mm
