FAHRION Heavy Duty HDC32C chuck ISO 7388-1 SK 50 AD projection length 70 mm

Application

For clamping tools with straight shanks without loss of concentricity or clamping force up to shank tolerance h10, for economic machining of individual and series parts with extremely high-precision machining results. HDC = heavy duty chuck, ideal for heavy-duty machining, roughing (TPC milling etc.) and finishing operations or machining high-strength or tough materials.

Execution

• High stability and radial rigidity thanks to reinforced chuck body on the HDC.
• Very high retention forces as the collet chuck fits completely in the chuck cone, the trapezoidal fine thread ensures optimum conversion of the tightening torques into clamping force.
• The ball bearing-mounted clamping nut prevents the collet chuck from twisting and reduces vibrations.
• Polished external and internal cone.
• With Balluff chip hole.
• Not compatible with the FAHRION CP clamping nut
  Use only in combination with FAHRION collet chucks.

Advantage

• System concentricity and repeat accuracy 3 µm at 3×D, when using a FAHRION precision collet chuck HP.
• Using the FAHRION wedge collet chuck creates a mechanical interlock on the Weldon surface of the tool, which completely and reliably prevents micro-creeping or the tool being pulled out.

Notes

The previous standard DIN 69871-1 was superseded by ISO 7388-1.

Delivery

1 piece precision collet chuck in accordance with ISO 7388-1 (DIN 69871), HDC Heavy Duty, without clamping nut.
