To the left is an 8" x 20" Elb hydraulic surface grinder
before rebuild.
To the right is a rear view of the same machine.
To the left the Elb is shown after disassembly has begun.
To the right disassembly of the major components is nearly complete. Most of
the electrics and all the hydraulics pictured here will be discarded.
Here the machine has been completely disassembled and stripped down to
just the castings.
The castings then go to our paint department where they will be sandblasted
to bare metal. They are then restored to new appearance utilizing a two-part epoxy paint
system.
Below is a shot of the finished electrical enclosure.
Engineering and drawings were provided by Fagor. The only other electrical components are
found in the pendant CNC control.
Above is a picture of the machine as
it is going back together after way grinding, hand scraping, painting and the machining of
mounting hardware for the ball screws in the X, Y & Z axis.
Pictured here is the fabrication of the
aluminum enclosure around the work area. It is made from angle and sheet aluminum screwed
together.
To the left is pictured the
finished enclosure with sliding Plexiglas doors.
To the right is a high precision 10 to 1 gear
reduction drive which attaches directly to the end of the longitudinal ball screw. This
enables the machine to perform creep feed grinding used in a slicing operation of
carbide and/or ceramic material with multiple diamond blades.
To the left can be seen our cast aluminum
box which houses the Gilmer pulleys and belt connecting the vertical ball screw and servo
motor. Directly above the ball screw adjacent to the servo motor is a bellows cover which
keeps dust and coolant off the ball screw as the spindle is raised.

Niagara Grinder installed at the customer's facility.
