Workhead
The work head spindle is made of nickel chrome EN-24 hardened and ground. It runs in gunmetal bush bearings. The drive to the workhead spindle which has MT-3, is by a step ‘V’ pulley. The speed obtained through this pulley can be reduced by another bigger size pulley provided in the workhead housing. The workhead is built for grinding operation both with stationary centre and revolving spindle. Oil holes are provided for lubrication.
Wheelhead
The rigid wheelhead spindle is made of nickel chrome steel EN-24 hardened and ground. It runs in white metal adjustable type bush bearings. The drive to the wheelhead is transmitted by two V-belts. Automatic wheelhead traverse in cross direction is on precision hand-scrapped ‘V’ and flat guide ways, and is hydro-mechanical type. The spindle is tapered (5o) at the front to receive the wheel flange. Oil holes are provided for lubrication of the bearing surfaces. Rapid approach is available in U-127 series and it is up to 40 mm.
Tailstock
The tailstock travels smoothly all along the length of table right upto the workhead.Â
Hydraulic/Electrical System
All standard equipments are used in both system.
Swivel Table
Table is arranged to swivel for taper grinding. For fine connections to be applied by the screw adjustment.
nternal Grinding Attachment
The hinged type Internal Grinding Attachment with its independent motor is conveniently located on the wheelhead. It has fast grinding action and it can be quickly swung into a grinding position. The work piece can be externally and internally ground in one setting. Taper hole can be ground by swivelling either workhead or table.
There are so many standard and special accessories that can be added to the machine as perÂ
