 Mid Cornwall Minerals          

Cutting and polishing service.

We can cut, slab  and  polish  to your specifications.

We no longer cut and polish specimens larger than about 150 mm mm square but we still offer the high quality service for all hand size specimens as we have always done.

Small items can sometimes be sent by post or courier, local collectors are always welcome to deliver and collect but  we do not offer a while you wait service especially while high speed  machinery is running.

Prices from as little as £25.00 per item for hand size specimens.

Our production machinery.

We are always being asked how we manage to produce such highly polished and flat specimens so we have added some pictures for interest.

This variable speed Engis 12" wet diamond flat lapper is the true workhorse of our operation, the various grades of diamond plates are held on to the master magnetic plate and are kept perfectly flat, small water jets around the hopper continuously feed water on to the diamond disc when working. High removal rates and the bonus of no contamination from the standard grit system is the reason for our preference for using this machine on specimens up to about 150 mm. 

Nearly all the final polishing is done using the lighter lapper shown below and is kept strictly for this operation, experimentation with polishing pads over the years has found that a rubber backed industrial non slip waterproof carpet is perfect for the job and being of industrial quality lasts for years. The 8" bumper rings which stop specimens hitting each other are nothing more than slices of heavy duty pvc  pipe.
