Fig. 93. A UNIVERSAL MILLING MACHINE FOR AUTOMATIC SCREW CUTTING AND OTHER OPERATIONS
A universal milling machine, see Fig. 93, is also a handy combination tool in that it can be used for drilling, cotter drilling, boring, profiling, key-seating, rack- and gear-cutting and other operations.
A buffing machine is made nearly like a grinder but leather, felt and rag wheels are used on the spindle and when either pumice-stone, crocus and rotten-stone is applied to them tool marks and scratches can be buffed out and the work polished when it is ready to be lacquered or nickle plated.

If you are buying new machines get them fitted with individual electric motors, as shown in Fig. 90, as this will save shafting, the time and cost of putting it up, the cost of belting, besides the time the machine is idle while the belt is broken and it is being laced again, the loss of power in transmission, when the machine is idle, etc., etc.; boiled down, these machines equipped with individual motors are the last word in modern shop practice and it is a good one for you to follow.

Whatever machines you order be sure to also order at the same time a full supply of tools to use with them for otherwise you may find when you have your machinery all set up and you think you are ready to start that you are minus the cutting tools and should this happen you will be in for another long delay.
