What is single spindle automatic lathe?
A single spindle automatic lathe is a modified form of turret lathe. These machines have an addition to a 6-station turret, a maximum of 4 cross slides. These cross slides are operated by disc cams.
What is automatic lathe machine?
In metalworking and woodworking, an automatic lathe is a lathe with an automatically controlled cutting process. Automatic lathes were first developed in the 1870s and were mechanically controlled.
How are automatic lathes classified?
Depending upon number of work spindles, automatic lathes are classified as: 1. Single Spindle Automatics. 2. Multi Spindle Automatics.
What are the advantages of automatic lathe?
Listed below are some of the key advantages of a sliding headstock automatic lathe:
- Accurate – Sliding headstock automatic lathes are known for their extreme accuracy and precision.
- Production – Sliding headstock automatic lathes can produce complete parts without much interference from a human operator.
What is the difference between automatic and semi automatic lathe?
The difference between automatic lathe and semi-automatic lathe is that the fully automatic lathe is controlled by computer, while the semi-automatic lathe is controlled by computer and manual.
What is the necessity of automatic lathes?
These simple but automatic lathes are used for producing short work pieces of simple form by using few cross feeding tools. In addition to parting some simple operations like short turning, facing, chamfering etc. are also done. Kinematic system and working principle of automatic lathes of common use.
What are the types of single spindle automatic lathes?
The types of single spindle automatic lathes
- Automatic cutting off machine.
- 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:
- Multiply cutting speed by 1000.
- Divide the product by the circumference of the workpiece/tool.
