Question: 1 / 400

What is the primary purpose of a lathe?

To drill holes in a workpiece

To remove material from a workpiece to create cylindrical shapes

The primary purpose of a lathe is to remove material from a workpiece to create cylindrical shapes. This machine is specifically designed to rotate the workpiece against cutting tools, allowing for precise shaping and finishing of materials such as metal, wood, or plastic. When a workpiece is mounted on the spindle of the lathe and rotated, various tools can engage the material, leading to processes like turning, tapering, and threading. This capability to create symmetrical products around a central axis is fundamental to many machining operations, making the lathe a vital tool in both manufacturing and repair shops.

While drilling holes and grinding surfaces are important machining operations, they generally require different types of equipment optimized for those tasks. A lathe focuses on the dynamic removal of material through rotation, which is essential for achieving the desired cylindrical profiles.
