PURPOSE: A driving apparatus of a milling tool rest is provided to reduce field claims by comprising the same level accuracy of continuously processing in comparison with two shafts. CONSTITUTION: A driving apparatus(130) of a milling tool rest(100) comprises a body(31), a driving shaft(140), first and second bevel gears(151,152), spacers(161,162) for adjusting a position, a first bearing, and a second bearing(171,172). The body forms an appearance. The driving shaft is assembled in the body. The first and second bevel gears are engaged each other to rotate the driving shaft. The spacers for adjusting the position are assembled in the body to improve the engagement of the first bevel gear with the second bevel gear. The first and second bearings are placed in upper and lower parts of the driving shaft. The first bearing or second bearing is formed without a seal. |
