Appliaction of CNC Parts
CNC turning machines excel in precision craftsmanship, fabricating a wide spectrum of parts
with diverse complexities.
Among these are shafts and axles, pivotal components in industries such as automotive and
aerospace.
The precision extends to the production of bushings and bearings, crucial for reducing friction
and ensuring smooth rotational movement in mechanical assemblies.
CNC turning further facilitates the creation of connectors, fittings, and fasteners like screws and nuts,
serving applications in plumbing, hydraulic systems, and across various industries.
The technology is also applied in the manufacturing of valves and valve components, contributing to
fluid control systems. Additionally, CNC turning is instrumental in crafting tooling components,
including inserts, toolholders, and bodies, enhancing efficiency and accuracy in machining operations.
In the automotive sector, CNC turning is harnessed for producing engine components, pulleys,
brackets, and specialized parts.
Company Profile
FAQ's
1. What's the general surface texture of CNC milled and turned parts?
The surface texture of machined milled parts is commonly around 3.2μm (or 1.6μm for more
recent machines). In the case of turned parts, a finer surface finish is achieved, reaching a
roughness of 0.8μm.
Notably, this enhanced surface texture in turning is accomplished without the necessity of adjusting
machining speeds.
2. The cost of CNC machining a part is contingent on various factors, including:
1. Material: The choice of material impacts costs, with some materials, like aluminum, being more
cost-effective to machine than others such as Inconel, due to considerations like tool wear and
cutting speeds.
2. Complexity: Parts with intricate features tend to be more expensive to machine. The complexity
of surface shapes, for example, directly influences machining costs.
3. Tolerances: Tighter dimensional tolerances increase the cost of CNC machining. It's crucial to
balance precision requirements with cost considerations to optimize overall expenses.
4. Surface Finish: Attaining mirror finishes necessitates specialized tools and machining strategies,
contributing to increased machining time and associated costs.
5. Quantity: The production volume plays a significant role in cost considerations.
Low-volume production tends to be more expensive per part, as initial setup and programming
costs are amortized over a smaller number of parts.
3. Can passivate my parts?
Passivation is a surface treatment that modifies the chemistry of specific metals. Our services
include passivation for purposes such as corrosion protection, increased durability, and enhanced
cosmetic appearance.
4. What are you shipping terms?
Our standard shipping terms, applicable to both rapid prototyping and regular production orders,
are Ex Works (EXW). Under these terms, the customer assumes responsibility for shipping, customs
clearance, and all associated fees once the goods have left our premises.
For express shipments, we follow the Delivered Duty Unpaid (DDU) model, placing the onus on the
client to pay import duty upon the goods reaching their destination.
