  • Automatic screw cutting machine.
  • Swiss type automatic lathe machine.

What is a lathe spindle?

Lathe spindles are used for machine-cutting of workpieces. They can also be referred to as workpiece spindles, as the workpiece is clamped via the chuck of the lathe spindle. The rotating workpiece is machined by the tool attached to the driven machine axis.

How are single spindle automats classified?

Single spindle automats: they machine single component at a time includes common machines such as automatic cutting off machines, swiss type automatic screw machine, etc. Multi spindle automats: they have 2 to 8 spindles. The spindles are arranged in a carrier, which is periodically indexed from position to position.

What are the two main purposes of the lathe spindle?

What are the two main purposes of the lathe spindle? To hold and rotate the workpiece during machining. You just studied 9 terms!

What is the formula for rpm on a lathe?

The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).

How is spindle rpm calculated?

To calculate spindle speed:

  1. Multiply cutting speed by 1000.
  2. Divide the product by the circumference of the workpiece/tool.
