page 33 Grinding an Angular Cutter with the End-Grinding Head
#2 Universal Cutter Grinder Machine, BROWN & SHARPE MFG. CO. PROVIDENCE, R. I., U. S. A.
page 33. END-GRINDING HEAD
Grinding the End Teeth of a Left-Hand. Spiral End Mill This operation is similar to the one in Fig. 7. In this case, however, the end mill is left-hand instead of right, and the ends of the teeth are being ground instead of re-cut. The above view has additional interest as it shows the under--
devise of the End-Grinding Head. The dog fastened to the side of the slide can be discerned, and the stops, adjustable along the T slot and which limit the motion of the slide, can be seen underneath. Adaptable as this head is, to a multitude of angular positions with the wheel, it is compact and staunch and develops practically no back lash in operation. The blade of the tooth rest is adjusted to the angle of the spiral teeth, in order to insure it a full contact with each tooth as the mill is rotated.

Care of the Machines
Did anyone think to save these old Things. Did they hate everything that built them into who they were?

Care of the Machines
As the life and efficiency of machines depend largely upon the amount of care taken of them, it is important that they should be kept clean and well oiled and that all repairs should be promptly attended to. In the following pages we offer some suggestions which, if carefully followed, will avoid annoyance and expense.
All worm gears and worms should be kept flooded with oil. We recommend an oil that is equal in all respects to the sample sent with the machine. As soon as the oil shows signs of becoming thick, it should be removed and new oil substituted. Suitable reservoirs for holding the oil are provided, having openings at 11 and 12,
The feed driving worm wheel at the left of the feed case may be oiled after lifting the cover 56, Fig. 3. The guiding ways of the cutter slide and the index worm and wheel should be kept clean and thoroughly oiled with a good machinery oil. Do not use the heavy oil except on the driving worm gears and worms. The cutter slide ways are oiled at 55,
Fig. 3 ;
the cutter slide feed screw and nut through the oil hole provided at 13, Fig. 3. Elevating Work Slide. In moving the work spindle slide when it is operated by power, be sure that all the clamps are loosened, and the hand elevating crank removed when one is used on shaft 21,
Adjustments. Careful attention is given to the adjustments of each machine before shipping and we caution against changing any of them except in case of wear or dismantling the machine. Instructions for adjusting end play of the cutter spindle, end play of cutter spindle worm, end play of feed screw, end play of index worm, and backlash between index worm and wheel are given on the instruction card sent with each machine.
