Freeport 10" x 20" and light 12" x 24" automatic surface grinders |
| View a video on the Freeport double column surface grinders. Well produced and in English) This shows grinding on several different models of the double column machines. Work shown includes flat thin plates, bases, columns and tables of machining centers, V-bed lathes, boring mill sub-tables etc. Click on the icon below. |
