CNC machining, standing for Computer Numerical Control machining, is the automated removal
of material from raw stock guided by computer-generated instructions. This process is versatile,
compatible with materials ranging from expanded polyurethane foam to nickel superalloys.
Common applications for CNC machining include fabricating various components, crafting
ornamental furniture, and producing turbine blades. The cost of CNC machining is contingent
on factors such as required precision, surface quality, quantity, material selection, and the overall
complexity of the part.
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
Turning, a manufacturing process known for producing rotational, axi-symmetric parts, boasts the
capability to create components with intricate features such as holes, grooves, threads, tapers,
and contoured surfaces.
This method is particularly adept at fashioning limited-quantity items, notably custom-designed
shafts and fasteners used in prototypes. Moreover, turning serves as a valuable secondary process
to enhance or add features to parts manufactured through alternative methods.
Examples of products crafted through turning include camshafts, crankshafts, baseball bats, bowls,
cue sticks, signboards, musical instruments, as well as table and chair legs.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services encompass both milling (3-axis, 3+2-axis, and 5-axis) and turning
processes.
For 3/3+2-axis CNC milling, we can machine parts with dimensions up to 2000 x 1500 x 200 mm
(78.7 x 59.0 x 7.8 in.). In the case of 5-axis milling, the maximum part size is 650 x 650 x 300 mm
(25.5 x 25.5 x 11.8 in.).
When it comes to CNC turning, we can handle parts with a maximum diameter of 431 mm (17 in.)
and a length of 990 mm (39 in.). For smaller parts, we recommend a minimum size of around
10 x 10 x 10 mm (0.39 x 0.39 x 0.39 in.).
Additionally, feature dimensions should not fall below 0.5 mm. Please note that our platform is
limited to a maximum size of 1000 mm (39 in.) for parts. If you have requirements beyond this
limit, feel free to contact our sales team for specialized assistance.
2. How long does delivery time and quotation take?
The delivery time for parts is intricately tied to their complexity. Low-complexity parts usually have
a lead time of 2-3 days, while moderate complexity extends to 2-5 days.
High-complexity parts may necessitate a lead time ranging between 5 and 15 days.
Quoting time is also linked to design complexity, ranging from 1 business day or faster for simpler
designs to 3+ business days for more intricate ones.
If you have a design that requires assessment and quoting, do not hesitate to contact our team.
3. Do you offer Quick-Turn CNC Machining?
Yes, we specialize in Quick-Turn CNC Machining, ensuring swift lead times for parts, with many
ready in just 3-4 days. Our services include an expedite option, and our team works closely with
you to fulfill your most time-sensitive requirements.
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.
