Fahrion Präzision HSPF40 Operating Instructions

Operating Instructions
Manually Operated Chucks HSPF with Safety Key
1. Product features
 compact design (taking little space and with no projecting jaws as occurs with
conventional chucks)
 contamination and dirt ingress almost eliminated
 higher clamping force and improved concentricity holding work with collets as
compared with a 3 jaw chuck
 large clamping range Ø 1,0 up to 42,0 mm (HSPF40) resp. Ø 4,0 up to 60,0 mm
(HSPF60) with free bar passage
 low surface stresses due to large clamping surface area of the collet, therefore
reducing pressure marks and distortion of thin walled work pieces
 standard, emergency, multi-range and profiled collets eliminate the time taken to
exchange of chucks and/or jaws when changing from round to profiled material
 no problem using on machines with CE-mark

X 4. Function
By turning the pinion approx. 1.½ to 2 turns using the safety key the clamping nut is
X
axially drawn against the collet, till it clamps. The pinion can also be tightened with
an accumulator or a pneumatically operated screw driver. The max. tightening
torque must not exceed 80 Nm both at HSPF40 and HSPF60. Higher torque can
lead to the breakage of the pinion.
5. Clamping
Insert collet. Assemble closing nut onto chuck body and turn radially so as to locate
the key into the keyway. Pushing lightly engage the thread by turning the safety key
supplied. Load component and tighten fully taking care not to exceed the max.
tightening torque. Never use an old three jaw chuck wrench → Danger of accident!
