POWER OPERATED 3 JAW CHUCKS - THROUGH BORE

Power Operated Hollow High Speed Chucks
are  designed  to  rotate  at  high  speeds  on  CNC lathes.  The  compact  construction  of  the  PHNC Chucks  offer  further  advantage  of  less  weight and  low  inertia  which  have  positive  influence  on the dynamic effect of CNC machine spindle. These chucks have a large through bore and are therefore suitable for bar work. The base jaws and top jaws weight are reduced in these chucks. This not only reduces  the  mass  but  also  lowers  the  centre  of gravity,  which  make  the  centrifugal  losses  low.

Chucks on CNC machines need to deliver high initial gripping force. We takes care of this in the design by making the chuck operate with a large drawbar pull. Consequently, the wedge is designed  to  have  large  contact  area  with  the base jaws

The weight of the body, base jaws and hard jaws are less, without the other essential criteria being sacrificed.

The chuck body is recessed to remove a large extent  of  material  to  reduce  the  weight.  (from sizes 250 mm to 500 mm)

The chuck body is forged steel. The guideways are hardened and ground.

The  wedge,  made  of  nickel  chrome  steel,  is  case
hardened  and  ground  on  all  the  working  surfaces.

The base jaws also made of nickel chrome steel, are case hardened and ground to match both the wedge and the body guideways.                                                  .

The base jaws are guided in the deep, wide, hardened slots in the body, which provide the ample bearing area necessary to withstand the forces resulting from high gripping action.            .

Provision  has  been  made  for  manual  lubrication  of the   sliding   surfaces   through   grease   nipples.

Serrations  are  ground  on  the  top  face  of  the  base jaws.   The   reversible   hard   jaws   have   ground serrations  on  the  bottom  to  match  the  base  jaws

The  various  radii  on  the  hard  jaws  in  conjunction with  the  serrations  are  designed  to  grip  a  wide range of diameters.

The   hardened   guideways   of   the   body,   nickel chrome  case  hardened  and  ground  base  jaws  and the  wedge  ensure  high  load  carrying  capacity  over a very long perio
