A CNC lathe machine is the Computer Numerical Controlled (CNC) version of a more conventional lathe. With this type of lathe, operations are controlled by a computer using values input by a trained operator. The biggest advantage in using a CNC lathe is that small and large parts can be fabricated to extreme precision and accuracy as demanded by many industries.
As expected, there is a financial investment in owning one of these machines so when it comes time to shop around for a CNC lathe for sale it is important to conduct research. In addition to finding a lathe that is affordable, an individual should choose a well-known brand and make the purchase through a reputable company that provides a warranty as well as repair and maintenance services as needed.
Choosing the Appropriate Machine
When looking at a CNC lathe for sale, it is important to make the right choice according to the jobs performed. Examples of things to consider include:
- Automation and Integrations
- Compatibility with existing CAD/CAM programs
- Cycle Time
- Fixtures
- Flexibility and Versatility
- Machine Horsepower
- Tool Capacity
- Type of Machine Control
- Type of Tool Holders
- Working Envelope Size
Additional Considerations
Also part of looking for a CNC lathe for sale are other considerations beyond the type of job. For instance, unless absolutely needed, a full forth axis rotary table should not be purchased. Sometimes people buy this type of lathe simply because they were swayed by the salesperson. However, with a full forth rotary axis table, clamping is done on a smooth.
As a result, there is simply no tooth engagement for additional strength such as tooth coupling. In addition, to get the unlimited indexing angle capability, tolerance is tight. Unfortunately, this equates to higher risk of damage or alignment if the machine crashes.
If someone is looking for a CNC lathe for sale with an HSK spindle and tooling, it is imperative to fully understand capabilities, as well as risks. Historically, a significant number of manufacturers have experienced problems with this particular tooling design. Because these lathes are more rigid, they hold tighter tolerances due to greater surface area contact on both taper and face.
The bottom line – as part of the process of buying a CNC lathe for sale, the right machine needs to be purchased and from a company like Sirco Machinery that can provide the guidance and insight required.
