Double Sided Fine Grinding Machines

These Double Sided Fine Grinding Machines are specially designed and built to withstand extreme conditions within a production environment while requiring minimal maintenance. These units are available with fine grinding platens from 20" up to 55" in diameter, and are specially configured for each application. Depending upon the application, these machines utilize fixed abrasive diamond or CBN suspended in resin, metal, and vitrified bonds to grind a wide range of materials to very tight specifications.

precision finishing The LFG series of twin wheel grinding machines are driven by three, variable speed motors for maximum process control flexibility. All three rotating machine components, the sun gear, top plate, and bottom plate, are independently controlled. Process down pressure requirements are pneumatically regulated and continuously monitored by a load cell.

The machines are operated through a color graphical interface to a programmable controller. The custom designed software prompts the operator for specific operating parameters and stores up to 200 different lapping and polishing routines containing up to 8 different process steps which can be recalled for later use.

The work carriers are pin driven for smooth action while processing fragile parts. Plate and carrier speeds and acceleration are precisely controlled through AC frequency inverters for gentle machine cycle start and end steps.
