Metal Milling Steel CNC Machining Service Custom CNC Metal Machining Stainless Steel Spare Part
In the realm of manufacturing, the CNC machining process, denoted by computer numerical control
machining, is a subtractive method that integrates computerized controls and machine tools.
Its fundamental principle involves the removal of layers from a solid material block.
The programming specifies the desired cuts in the metal, coordinating with the corresponding tools
and machinery to execute the machining task in an automated manner.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.

CNC Machining Applications
CNC milling, renowned for its efficiency, accuracy, and the elimination of manual labor, finds
widespread application across diverse industries. Machine shops, offering critical services for
prototypes and full production runs, play a pivotal role in the manufacturing process.
Notably, the electronics industry heavily relies on CNC machines to produce electronic enclosures
and circuit supports. In the commercial sector, CNC cutting heads contribute to the creation of
affordable parts, reducing production costs and saving time.
The oil and gas industry utilizes CNC machines for the production of various components like drill
bits, cylinders, pins, rods, and valves. Similarly, CNC milling tools are indispensable in the medical
industry for creating implants, surgical equipment, and medical devices.
Finally, the aerospace industry benefits significantly from CNC machined parts, utilizing this
technology for the production of complex, customized components essential for aerospace equipment.
Company Profile
FAQ's
1. What industries do you typically work in? Who are your typical customers?
Our expertise spans across a wide array of industries, making it challenging to pinpoint ones we
haven't engaged with! Our customer base includes heavy equipment manufacturers, general
commercial businesses, and companies in industrial, transportation, medical, and consumer
sectors, among others.
While our clientele is distributed globally, encompassing the United States, Europe, and beyond,
they share a common need for top-notch parts machined to precise specifications, delivered
punctually, and within budget.
2. What are your tolerances for machined parts?
For machined parts, our tolerances typically adhere to +.005”/- .005” local tolerances across most
metal geometries and +/- 0.010" for plastics. It's important to note that these tolerances may vary
for large parts, especially concerning flatness after heat treatment.
For an "As Milled" finish, a minimum surface finish of 125 is maintained for CNC parts.
Fabricated parts come with a 0.010” dimensional tolerance and a 1° angular tolerance.
Tapped holes not explicitly designated as features in the CAD model may be machined to the
diameters specified.
Additionally, no surface treatments, such as anodizing, bead blasting, iriditing, powder coating, etc.,
will be applied unless expressly paid for and acknowledged.
3. Can make design drawings for me?
Unfortunately, we don't offer an independent product design service. However, for all approved orders,
we provide a Design for Manufacturing review. This involves collaborating with our clients to enhance
their 2D and 3D drawings, ensuring better manufacturability, resolving design conflicts, and reducing
production costs. Learn more about preparing your CAD drawings for manufacturing.
4. How long does a quotation take?
Typically, we aim to respond to Requests for Quotation (RFQ) within a few days of receipt.
In the event of any delays, rest assured that we will promptly notify you of the situation.
