The document summarizes the main parts of a lathe machine. It lists 15 key components: the headstock, spindle, chuck, tool post, compound rest, cross slide, carriage, ways, tailstock quill, tailstock assembly, bed, lead screw, feed rod, longitudinal and transverse feed control, and split nut. The carriage, ways, and apron are involved in moving cutting tools into the workpiece. The headstock, spindle, chuck, and tailstock quill are used to hold and rotate the material being machined.

machine

4. A lathe machine is composed by:

5. 1. HEADSTOCK: IT MOUNTED IN A FIXED POSITION ON THE INNER WAYS IN THE
MACHINE.
2. SPINDLE: IT IS LOCATED IN THE HEAD AND ALLOWS TO WORK WITH GREAT
VALUES.
3. CHUCK: 3-JAW OR 4 JAWS (INDEPENDENT) TO HOLD THE PART BEING
MACHINED.
4. TOOL POST: IT TO MOUNT TOOL HOLDERS IN WHICH THE CUTTING BITS ARE
CLAMPED.
5. COMPOUND REST: IT MOUNTED TO THE CROSS SLIDE, IT PIVOTS AROUND THE
TOOL POST.
6. CROSS SLIDE: IT USES A HANDWHEEL TO FEED TOOLS INTO THE WORKPIECE.
7. CARRIAGE: IT MOVES ON THE OUTER WAYS. USED FOR MOUNTING AND
MOVING MOST THE CUTTING TOOLS.
8. WAYS: IT IS A GUIDE THAT IS ON THE INSIDE AND OUTSIDE OF THE MACHINE.

6. 9. TAILSTOCK QUILL: IT KEEPS THE CENTER OF THE LATHE.
10. TAILSTOCK ASSEMBLY: IT CAN SLIDE AND ADAPTS TO ANY POSITION OF THE
WORKPIECE.
11. BED: IT PROVIDES A HEAVY RIGID FRAME ON WHICH ALL THE MAIN
COMPONENTS ARE MOUNTED.
12. LEAD SCREW: IT FOR CUTTING THREADS.
13. FEED ROD: IT SERVES TO ADVANCE OR CARRIAGE RETURN BY A CLUTCH.
14. LONGITUDINAL & TRANSVERSE FEED CONTROL: IT CONTROLS THE MOVEMENT
OF THE CARRIAGE USING LEVERS.
15. SPLIT NUT: IT IS USED TO ACTUATE AND MOVE THE CARRIAGE WITHOUT USING
A CLUTCH.
16. APRON: IT HAS THE MECHANISM AND CONTROLS FOR MOVING THE CARRIAGE
AND CROSS SLIDE.
