Advantages of CNC Machining
CNC milling and turning processes offer a multitude of advantages.
They are characterized by high precision and repeatability, capable of achieving tight tolerances
ranging from +/-0.001" to 0.005", depending on specific requirements.
CNC machines can be programmed to operate continuously, 24 hours a day, 7 days a week, making
them an excellent choice for on-demand part production.
Utilizing standard tooling, CNC machining services are particularly valuable for creating custom,
one-off parts. This versatility makes it ideal for replacing legacy components or providing specialized
upgrades to customers.
Moreover, CNC machining can be scaled for single-part production to large runs exceeding 10,000
units. Depending on factors like the quantity, size, and complexity of the parts, CNC machined
components can have remarkably short turnaround times, with some produced in as little as one day.
When accounting for shipping and delivery, even tight deadlines can often be met within a week.
Another significant advantage of CNC technology lies in the mechanical properties it can achieve.
Unlike processes such as injection molding or additive manufacturing, which may alter the material
through thermal transformation, CNC machining maintains all the desirable mechanical properties
of the chosen metal or plastic.
CNC milling and turning can work with over 50 industrial-grade materials, including aluminum,
brass, bronze, titanium, stainless steel, PEEK, ABS, and zinc. The only prerequisite for CNC
machining is that the material has sufficient hardness to be securely fixtured and machined.
Challenges of CNC Machining
While CNC machining offers high-performance capabilities, there are certain challenges to consider.
Geometric complexity can impact costs, making simple and chunky parts more cost-effective for
CNC milling and turning processes.
Design limitations may arise due to tool access, with the level of complexity depending on the
number of machine axes employed. In essence, more axes allow for the creation of more intricate
features.
Another challenge is the initial cost of CNC machining. Setting up and programming CNC mills and
lathes requires the expertise of trained professionals. However, this setup cost can be fixed and
become more economical when used for multiple parts.
Cost savings can also be achieved by minimizing the need for part repositioning. For multi-faceted
geometries, machining at 5-axis or higher can sometimes be more cost-effective as it eliminates
the manual repositioning step.
Additionally, the wire EDM machining method may be relatively slow and expensive compared to
other processes. It is also limited to electrically conductive materials, which can reduce the range
of applicable materials.
