Company Profile
Advantages of CNC Machining
CNC milling and turning are highly precise and repeatable processes
that can achieve tight tolerances
ranging from +/-0.001″ to 0.005″, depending on specific requirements.
CNC machines can be programmed to operate reliably 24/7, making them ideal for on-demand part
production.
CNC machining services are especially valuable for creating custom CNC parts, whether it's for replacing
legacy components or delivering specialized upgrades to customers.
Additionally, CNC machining can efficiently scale from producing one-off parts to runs exceeding 10,000
units.
Turnaround times for CNC machined parts can be remarkably short, often as quick as one day, and with
shipping and delivery, deadlines can be met within a week.
Another significant advantage of CNC technology lies in the mechanical properties it can achieve.
Unlike processes like injection molding or additive manufacturing, which may thermally transform
materials, CNC machining preserves all the desirable mechanical properties of the chosen metal or plastic
by removing material from the bulk.
CNC milling and turning can work with over 50 industrial-grade materials, including aluminum, brass,
bronze, titanium, stainless steel, PEEK, ABS, and zinc. The primary requirement for CNC machining is
that the material has sufficient hardness to be fixtured and cut effectively.
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.
