CNC machining, distinct from traditional machining, accomplishes the same metal cutting, drilling,
milling, boring, grinding, and other metal forming and removal functions, but with the key
difference of utilizing computer numerical control instead of manual operation by a skilled machinist.
Traditional machining involves a manual approach where a machinist operates the machine, removing
or forming metal based on specifications from designers and engineers.
This process employs various tools such as turn wheels, dials, switches, chucks, vices, and cutting
tools made of materials like hardened steel, carbide, and industrial diamond.
In CNC machining, the automated process is driven by code developed by programmers, ensuring
consistent precision from the first cut to subsequent repetitions. Commonly used in digital
manufacturing and occasionally in low-volume production, CNC machining allows for easy revisions
and alterations for modifications and diverse materials.
While traditional machining is still relevant, CNC machining has largely superseded it in
manufacturing, fabrication, and industrial production due to its enhanced precision and automation.
Product Details
Stainless steel is highly resistant to corrosion and rust, making it suitable for situations
where a part may be exposed to the elements for a long period of time.
Stainless steel is also fairly malleable and ductile.
| Common Stainless Steel Materials | |
| No. | Properties |
| Stainless steel 304/304L | The most common alloy and is known for its pristine surface finish. It has significantly higher corrosion and oxidation resistance. Typically used in the manufacture of sensor parts, shafts, machinery parts, medical parts, and more. |
| Stainless steel 316/316L | It is slightly higher levels of chromium and nickel that exhibits improved heat tolerance, resistance to creep and pitting, and excellent tensile strength. Typically used in the manufacture of sensor, chemical & pharmaceutical equipment parts, and more. |
| Stainless steel 303 | It is a non-magnetic, austenitic stainless steel with good resistance to mildly corrosive atmospheres, but significantly less than 304. Typically used in the manufacture of screw, gears, fittings, bushings, shaft, and more. |
| Stainless steel 420 | It is a martensitic stainless steel with good corrosion resistance as well as strength and hardness. It is capable of being heat treated to a hardness of HRC 51 minimum. Typically used in the manufacture of pivots, cams, pump shafts, surgical instrument parts, valve components, and more. |
| Stainless steel 440C | It is a martensitic stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58 - 60 HRC. Typically used in the manufacture of valve seats, piston, shaft, and more. |
| Stainless steel 430 | It is a non-hardenable ferritic stainless steel with excellent finish quality. It has good corrosion resistance with good formability and ductility. Typically used in the manufacture of fittings, flanges fasteners, piston, and more. |
| Stainless steel 430FR | It is a free-machining solenoid quality alloy, ideal for parts that require corrosion resistance and high electrical resistivity. It has excellent corrosion resistance in fresh water, gaseous, moderately acidic, and low chlorine environments. |
| Stainless steel 630 | It is commonly referred to as 17-4 and is a precipitation-hardening martensitic stainless steel that offers superior corrosion resistance. It is magnetic, readily welded. Typically used in the manufacture of sensor housing, valve, pump shaft, and more. |

Applications of Stainless Steel Parts
CNC turning services play a pivotal role in diverse industries, notably in transportation sectors
such as aerospace, automotive, mass transit, rail and locomotive, military, and trucking.
Within these sectors, CNC machines are employed for designing crucial transportation equipment,
including headnuts, gear blanks, bearing blocks, levers, axles, and rotors.
In the construction industry, CNC machines are utilized to create robust bolts and screws from
metals like stainless steel and aluminum, essential for heavy-duty applications.
Additionally, CNC turning services are integral to the production of various auto parts, including
engine components like cylinder heads, connecting rods, and camshafts, transmission parts such
as shafts and rings, as well as suspension components like sway bars, control arms, and tie rod
ends.
The aviation industry also heavily relies on CNC turned parts, utilizing them for the customization
and creation of probes, joint connectors, fasteners, and engine and aircraft components, often
opting for titanium due to its capability to withstand extreme temperatures.

FAQ's
1. What industries do you typically work in? Who are your typical customers?
It's hard to find an industry we haven't collaborated with! Our clientele represents diverse
sectors, including heavy equipment manufacturing, general commercial enterprises, and businesses
in industrial, transportation, medical, and consumer domains, among others.
Our customer base extends across the United States, Europe, and beyond. What unites them is a
shared requirement for precision-machined parts delivered on time and within budget constraints.
2. Can you ensure my designed component dimensions and tolerances are suitable for
production?
Count on our team of experienced professionals to provide robust "Design for Engineering" (DFM)
support, ensuring that your designed component dimensions and tolerances are suitable for
production.
We understand the need for quick turnarounds during the idea testing phase and are committed to
providing prompt quotes. For a detailed overview of the entire order progression, refer to our
production process page.
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?
In our standard shipping terms, we utilize Ex Works (EXW) for both rapid prototyping and regular
production orders. This means that once the goods depart our premises, the customer is responsible
for shipping, customs clearance, and all related fees.
Express shipments follow the Delivered Duty Unpaid (DDU) arrangement, where the client takes on
the responsibility of paying import duty upon the goods' arrival at the destination.
