CNC machining is a key method of small and large part fabrication. Many industries rely on this type of machining because it produces extremely accurate and precise results. While there are tremendous benefits in purchasing a CNC machine, there are some key things to consider.
Things to Factor In
All types of CNC machining involve a financial investment and while much of the work is automated, there needs to be a certified operator onboard who performs a wide range of operations. Before making a purchase, a number of factors should be carefully analyzed to include:
- Cycle Time
- Parts Availability
- Cost Savings Potential with a Reduction of Staff
- Machine Tool Options
- Repair and Maintenance
- Rigidity Tighter Tolerances
- Trade in Value / Resell
Additional Options for Consideration
In addition to the above, CNC machining is typically sold with options installed. The goal is to choose the appropriate machine according to the type of work being conducted. Following are some of the common installed options but an individual will find the selection process easier by working with a trusted company such as Sirco Machinery.
- Control Related Options – These include things like program memory, macro programming, and tool life management
- Machine Tools – Keep in mind that in addition to the tools already installed, an individual can often add tools for CNC machining. Of the tools expected are a parts catcher, signal light, work light, barfeeder interface, conveyors, M-codes, tool breakage detector, coolant chip flush, scales, and auto-door, pneumatic, or servo.
- Options for Fixtures – As part of this are light curtains, M-codes, two-hand anti-tie down, part present detector, height of proposed fixture, PLC, and hydraulic or pneumatic clamping
Although CNC machining of various kinds can be purchased used as a means of saving money, this generally comes with challenges. For this reason, it is always recommended that individual buy machining new. Even though there is an upfront financial investment, it pays off in the long-run and eliminates risks.
Unlike used CNC machining that comes with virtually no support for maintenance and repair, the professionals with Sirco provide service that goes beyond the initial sale. For that reason, it makes more sense to purchase a new machine, one that will handle the type and volume of work but also CNC machining that offers necessary tools for the job.
