CNC Turning And Milling Products Metal Parts CNC Machined Stainless Steel Parts
We possess extensive CNC machining capabilities, crafting a diverse range of parts,
from straightforward "as machined" workholdings to intricate geometries.
Our manufacturing facilities are equipped with a variety of CNC mills and turning centers,
and upon request, we can utilize EDM and grinders.
Embracing precision, we provide tolerances as tight as 0.05 mm (0.0020 in), coupled with
swift lead times starting from just one business day.
Product Details
CNC machining materials are generally grouped into three primary categories: plastics, soft metals,
and hard metals. This classification includes materials such as aluminum, bronze, copper, ceramics,
plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.

POM | High stiffness, excellent thermal & electrical properties, relatively brittle |
CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design complexity,
the number and size of features, materials used, surface finish, and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production time and cost.
CNC Milling Tolerances | ||
Limits for nominal size | Plastics | Metals |
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
Over 6mm to 30mm | ±0.2mm | ±0.10mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 120mm to 400mm | ±0.5mm | ±0.20mm |
Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes, below 0.5mm on your technical drawing. |
Specialist industries
CNC milling, characterized by its efficiency, precision, and automation, is a transformative force
across various industries. Machine shops, serving as crucial entities in the manufacturing process,
provide essential services for prototypes and full production runs.
The electronics industry relies extensively on CNC machines for crafting components such as
electronic enclosures and circuit supports. In the commercial sector, CNC cutting heads play a key
role in producing cost-effective parts, streamlining production processes.
The oil and gas industry utilizes CNC machines for the fabrication of drill bits, cylinders, pins, rods,
valves, and more. The medical industry benefits from CNC milling in the production of diverse
components, including implants, surgical equipment, and medical devices. Lastly, the aerospace
industry demonstrates a constant demand for CNC machined parts, employing this technology to
create intricate, customized components vital for aerospace equipment.
Company Profile
FAQ's
1. What cosmetic standards do you guarantee?
Upholding stringent quality standards, our CNC machined parts undergo standard deburring
and edge-breaking procedures. Clear indications in technical drawings are required for any critical
edges that should be left sharp.
Surfaces are guaranteed to be defect-free, ensuring the absence of scratches, dents, stains,
blemishes, hanging marks, and minor imperfections. Critical surfaces (primary (a) side, as outlined
in technical drawings) will be meticulously free from mill steps and other marks.
On the secondary (b) side, minor hanging marks and up to 2 minor defects are considered within
acceptable limits. Additionally, a range of post-processing and finishing methods can be applied to
enhance surface roughness, visual aesthetics, and wear resistance for CNC machined parts.
2. How much does CNC machining cost?
The cost of CNC machining is determined by factors such as complexity, quantity, and lead time.
To obtain a precise cost estimate, we encourage you to submit a 3D CAD model, enabling us to
provide an interactive quote accompanied by design for manufacturability (DFM) feedback.
Our use of proprietary software and automated fixturing processes eliminates upfront non-recurring
engineering (NRE) costs, making CNC machining a cost-effective choice for quantities as low as 1
to 200 parts. While prices may be comparable or slightly higher than 3D printing, CNC machining
delivers superior material properties and surface finishes.
3. Do you offer Quick-Turn CNC Machining?
Indeed! Our Quick-Turn CNC Machining services provide fast lead times for parts, with many
available within 3-4 days. We also offer an expedite option, and our team is dedicated to working
closely with you to meet your most pressing deadlines.
4. What if I am not completely satisfied with the parts I receive?
We assure the quality of our materials and workmanship based on the terms specified in the initial
order and the information you provide. Disputes arising from subjective assessments will be handled
by our management, who will act in good faith to secure your complete satisfaction.
Our sustained success hinges on earning your confidence in our ability to consistently meet and
exceed reasonable expectations.
