FORMULA SYSTEM

After gained long-standing experience acquired in the design and realization collet chuck for C.N.C. lathes Unilock presents FORMULA SYSTEM in the following three models: 1) Thrust System FORMULA PUSH 2) Pull System FORMULA PULL 3) Expansion System FORMULA IN      


ADVANTAGES


THE FORMULA SYSTEM IS MADE UP FROM A FIXED “BASE” INTERFACED TO THE LATHE WITH ASA ISO COUPLING: The composition Formula of the “Italian Style” spindle has many variables Great adaptability and flexibility to specific needs of any mechanical machining On the “BASE” is developed the piece blocking system according to the machining procedure


FEATURES


FORMULA PUSH The collet remains stationary, coupled to the spindle clamping nut while the rear tapered cylinder advances for tightening. FORMULA PULL The collet couples directly with the spindle cone. FORMULA IN The collet remains stationary and the pin must be pushed inside the conical shape to make the collet expand radially.  •UNILOCK_SISTEMA_FORMULA_1


FORMULA PUSH – Thrust system


•UNILOCK_SISTEMA_SPINTA_SMSIn the thrust system FORMULA PUSH the collet remains stationary, coupled to the spindle clamping nut while the rear tapered cylinder advances for tightening. The collet is changed quickly by simply loosening the front clamping nut. The collet closes parallel to the bar, without interfering on its position. Main uses Applied to the lathe counter-spindle, tighten the piece without loading the spindle axis and do not trigger the alarm of the C.N.C. Suitable for bar and secondary machining, with excellent tightening repeatability. All ITALIAN STYLE models are COMPATIBLE  with DIN 6343 collets.


ADVANTAGES


  • Minimum clearance
  • Quick change clamping nut
  • Bar clamping with stationary collet
  • Does not mark the surface of the piece
  • Fewer machine downtimes
  • Machining tolerance lower than DIN tables
  • Range of machining:  -1.0 mm
  • Clamping of raw pieces (rolled, forged, castings)

FORMULA PULL – PULL system


In the pull system FORMULA PULL the collet couples directly with the spindle cone. Main uses Applied to the lathe main spindle it is suitable for bar machining. Moreover, thanks to the construction flexibility of the system, it allows easy specific solutions (drawn bars, rectified items, rolled items, pipes). The rubber coating of the collets does not allow shavings to pass inside the spindle. QUICK CHANGE” COLLETS The system allows a fast front removal of the collet. In this way, replacement or disassembly collet cleaning operations result easier and quicker, without dead times. All UNILOCK SMH collet-chucks  are COMPATIBLE with original HAINBUCH collets


ADVANTAGES


  • Strong clamping strength
  • Machining tolerance lower than DIN tables
  • Minimum weight and small  clearance
  • Range of machining:  -1.0 mm
  • Strength for a noteworthy decrease of the vibrations of the piece machined
  • Clamping of raw pieces (rolled, forged, cast elements)
  • Quick collet change.

FORMULA IN –  Expansion system


In the expansion system FORMULA IN the collet remains stationary. The pin is pushed inside the clamping collet to make expand radially. Strong clamping force, suitable for heavy duty machining on raw pieces. Great concentricity accuracy. Main uses Secondary machining of bored piece to complete the external machining on the counter-spindle. Applied to the main spindle, it blocks the raw pieces (castings) and bored pieces internally. Allows to load the piece with automatic systems (robots).


ADVANTAGES


  • Minimum clearance
  • Piece clamping with stationary collet radial clamping without pull-back effect
  • Does not mark the surface of the piece
  • Fewer machine downtimes
  • High repeatability accuracy
  • Machining tolerance lower than DIN tables
  • Range of machining: +0.5mm / +1.00 mm
  • Clamping of raw pieces (rolled, forged, castings) 01_FORMULA SYSTEM_in 01_Unilock_FORMULA SYSTEM_5
