Salient Features:

Attachment for CNC lathe, Easy to mount on VDI 30 or VDI 40 turret, Turned sphere heads are  lapped, Sphere to be lapped is held in machine spindle.

Specification:

Work piece accuracies:

Level of Development:

• Quality wise attachment can provide the output of form ( sphericity) less than 0.008mm and surface roughness value (Ra) less than 0.03 micro meter

Status of Commercialization:

• Ready for Technology Transfer

Major Raw materials Utilised:

• Generally cast Iron and for finishing process standard felt made of woolen material utilized. Process uses lapping paste with different grades.

Major Plant Equipment and Machines required:

• CNC lathe and Electric power to run its motor drive.

Techno economics:

• It is unique attachement for CNC lathe. There are no attachment manufacturers for CNC machines to produce finishing process on spherical parts. Attachment is economical. Form and surface finish achieved is in micrometer level.
