Another machine made by the same company is shown in Fig. 6. This is a good example of the class of machines which are commonly known as " slab millers." It is now generally conceded that the limiting factor of milling operations is determined by the strength and durability of the cutter. These are greatly extended by having a thoroughly rigid frame and a powerful driving train for the feed of the machine.
There is no class of milling that meets with failure so often as the apparently simple operation of slabbing. The immense stress imposed on the machine by the great width of cut that it is expected to take, invariably causes chattering to an alarming degree, —the great bug-bear of milling to the inexperienced operator. The only solution of the problem lies in the proper selection of cutters, the use of a fast feed, and a machine of ample proportions to stand the strain. The liberal proportions of the machine illustrated in Fig. 6 show careful consideration of all these factors on the part of the designer. |
