Machine components and motion directions
There are many forms of CNC turning centers… Universal slant bed Chucker slant bed Twin spindle horizontal Single spindle vertical Twin spindle vertical Mill/turn machines Gang type Sliding headstock Here is a list of machine types that we provide introductions to. Again, (using the presentation links slide) you may want to show only the style of machine that you know students will be working with. In all cases… X will be the diameter controlling axis Z will be the length controlling axis

This is the last slide in a series that helps you introduce the most basic components (headstock, chuck, tailstock, and turret). Universal style slant bed turning center Home Lesson topics

That’s why it’s called a “universal” style
A universal slant bed turning center can perform all types of turning applications: Chucker work Shaft work Bar work This slide helps you explain why this machine type is called a universal style. Universal style slant bed turning center Home Lesson topics

- + Z Axis Universal style slant bed turning center Home Lesson topics
The next series of slides is an animation that helps you illustrate the Z axis. After that, we show the X axis. Universal style slant bed turning center Home Lesson topics

Z Axis - + Universal style slant bed turning center Home Lesson topics

- + Z Axis Universal style slant bed turning center
Z is the length controlling axis Z Axis - + Universal style slant bed turning center Home Lesson topics

X Axis - + Universal style slant bed turning center Home Lesson topics

- + X Axis Universal style slant bed turning center
X is the diameter controlling axis Universal style slant bed turning center Home Lesson topics

- + X is DIAMETER X3.0 X Axis Universal style slant bed turning center
If you want to turn a 3.0 inch diameter… X Axis 3.000 - Also be sure to point out that, for most turning centers, the X axis specifies the diameter of the workpiece being machined. X3.0 X3.0 will be the commanding word Universal style slant bed turning center Home Lesson topics

- + X is DIAMETER X3.0 Once again:
X Axis Once again: X is always the diameter-controlling axis Z is always the length controlling axis 3.000 - Also: X+: always gets bigger in diameter Z+: always away from the spindle Upcoming slides help you illustrate all other popular forms of CNC turning centers. Point out that they all share two things in common. X always controls diameter – Z always control workpiece length. And X plus is always getting bigger in diameter – Z plus is the direction away from the spindle face. X3.0 Universal style slant bed turning center Home Lesson topics

Headstock Chuck Turret NO Tailstock!
Same basic components, but… Headstock Chuck Turret NO Tailstock! We do the same things for chucker style, twin spindle horizontal style, single spindle vertical style, and all other styles of CNC turning centers. First we introduce the main components - and then we introduce the axes (including polarity). Chucker style slant bed turning center Home Lesson topics

A chucker-style turning center cannot perform shaft work!
X Axis - + X is still the diameter controlling axis… …Z is still the length controlling axis Z Axis - + Z travel is usually quite short Graphic for chucker style slant bed turning center. A chucker-style turning center cannot perform shaft work! Chucker style slant bed turning center Home Lesson topics
