DRAW-IN LONG NOSE COLLETS SW&B CLAMPING SURFACE DESIGNS

 

SMOOTH – STANDARD

  • Standard draw-in long nose collet

GROOVED

  • With additional grooves

CARBIDE COATING

  • Carbide coating possible for all shapes
  • Roughened surface
  • Higher clamping force
  • Repeated / afterward coating possible

EXTENDED CLAMPING LENGTH

  • Can be used for long workpieces with multiple grooves
  • Higher wrap around at the workpiece perimeter, therefore more force to clamp
  • More stable clamping for long workpieces

SHORTENED CLAMPING LENGTH

  • Application for workpieces whose geometry behind the clamping diameter shouldn’t be damaged
  • Used for short workpieces so the ejector can be lead closer to the clamping diameter

DRAW-IN LONG NOSE COLLETS SW&B SHAPES

SQUARE

  • Suitable for clamping square material

HEXAGON

  • Suitable for clamping hexagon material

SPECIAL PROFILES

  • Various profiles can be realized by ram EDM or wire EDM
  • Profiles can be adapted individually to the workpiece

SPECIAL CONTOURS

  • Complex contours can be realized by hard milling, hard turning and grinding
  • Already possible with smallest diameters from 0.2 mm

ECCENTRIC

  • Eccentric bore can be eroded individually according to application
  • Through hole or offset hole is possible

STEP BORES

  • Step bores are suitable for simultaneous clamping of several diameters of a workpiece
  • Very high precision as both step bores are ground in one step

INNER CONICAL

  • For gripping conical workpieces
  • The taper angle of the collet is precisely adapted to the workpiece

DRAW-IN LONG NOSE COLLETS SW&B CLAMPING S-SLOT DESIGNS

S-SLOT

  • High and constant clamping force
  • Clamping with virtually no clamping marks
  • Alternatively usable for profile material (corner clamping)
  • Prevents the entry of machining chips, as the collet closes almost completely
  • Easy to clean after use

L-SLOT

  • High and constant clamping force
  • Clamping with virtually no clamping marks
  • Alternatively usable for profile material (corner clamping)
  • Prevents the entry of machining chips, as the collet closes almost completely
  • Easy to clean after use
  • Ideal for clamping short clamping surfaces

W-SLOT

  • High and constant clamping force
  • Clamping with virtually no clamping marks
  • Alternatively usable for profile material (corner clamping)
  • Prevents the entry of machining chips, as the collet closes almost completely
  • Easy to clean after use

Z-SLOT

  • High and constant clamping force
  • Clamping with virtually no clamping marks
  • Alternatively usable for profile material (corner clamping)
  • Prevents the entry of machining chips, as the collet closes almost completely
  • Easy to clean after use

THIN SLOTTED

  • Clamping with virtually no clamping marks
  • Prevents the entry of machining chips, as the collet closes almost completely
  • Recommended for small bore sizes

DRAW-IN LONG NOSE COLLETS SW&B WEAR REDUCTION

CARBIDE INSERT

  • High wear resistance
  • Prevents pressure marks on the workpiece
  • Higher service life

BL COATING

  • Smooth surface
  • Fewer clamping marks on the material
  • Especially suitable for material with poor gliding properties
  • Prevents the welding of the material in the collet

PREMIUM BLUE COATING

  • Economical alternative to collets with carbide insert
  • High wear resistance
  • Can also be used for special shapes
  • Are completely coated on the functional surfaces like cone and shaft therefore more durable

DRAW-IN LONG NOSE COLLETS SW&B ADDITIONAL VERSIONS

INTERNAL STOP

  • Suitable for manual loading of the machine at a certain length
  • Prevents the displacement of the workpiece at high axial forces
  • Used to stabilize the workpiece when the clamping length is too short

INSERT AID

  • Is inserted in main spindle collets
  • Is mainly used for small diameters
  • Minimizes vibrations as the bar material is supported along its total length

BUSH

  • Is inserted in main spindle collets
  • An alternative to the insert aid
  • Is mainly used for medium to large diameters
  • Absorbs the vibrations of the bar material, supports it at the back and keeps it axially aligned

SUPPORTING BUSH

  • Is inserted in sub spindle collets
  • Minimizes vibrations as the bar material is supported along its total length and keeps it axially aligned
  • Ejection is made possible in a process-safe way

EJECTOR & INNER COOLING

  • Mechanical ejection of the workpieces
  • If required internal cooling of components can be integrated
  • For flushing the clamping surface
  • Simple change of the ejector within one collet type possible

UP VERSION

  • High precision

UUP VERSION

  • Highest precision

SEALED

  • Prevents the entry of machining chips
  • The whole slot area can be sealed
  • Resealing possible
  • Not usable with high pressure flushing in the machine
