Difficulty: Easy
Correct Answer: True – the table can swivel horizontally and be fed at an angle
Explanation:
Introduction / Context:
A universal milling machine extends the capability of a plain (horizontal) mill by allowing the table to swivel in the horizontal plane. This is essential for cutting helical gears, spirals, and other angular features synchronized with table feed.
Given Data / Assumptions:
Concept / Approach:
Swiveling the table changes the feed direction relative to the cutter. When geared (with the dividing head) to the table feed, the work can be advanced axially as it rotates, generating a helix. This capability differentiates the universal mill from a plain mill, whose table is fixed parallel/perpendicular to the spindle.
Step-by-Step Solution:
Swivel the table to the required helix angle within machine limits.Engage feed at the set angle; optionally gear the dividing head to the feed screw for helices/gears.Perform milling with the desired angular relationship, impossible on a non-swiveling plain mill.
Verification / Alternative check:
Manufacturer manuals show swivel graduations and helical milling charts, confirming angled feed capability.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing universal with omniversal (which also tilts vertically); overlooking the need to realign after angular work.
Final Answer:
True – the table can swivel horizontally and be fed at an angle
