CNC machining, which stands for Computer Numerical Control machining, involves the automated
removal of material from raw stock based on computer-generated instructions.
This versatile process can be applied to nearly any material, ranging from expanded polyurethane
foam to nickel superalloys. Common applications of CNC machining include the fabrication of parts
for various industries, ornamental furniture, and the production of turbine blades.
The cost associated with CNC machining is heavily influenced by factors such as required precision,
surface quality, quantity, material composition, 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. |

Company Profile
FAQ's
1. What type of design files does We accept for quoting?
For precise and prompt quoting, we exclusively accept 3D CAD files in STL, STEP, or IGES formats.
For 2D drawings with reference dimensions, please submit them in PDF format. It's essential to
include comprehensive manufacturing information as part of your technical documentation.
Informal communication through Whatsapp, email, etc., will not be deemed acceptable for
manufacturing purposes.
2. How does compare to other suppliers on price?
While direct comparisons can be challenging, generally, We offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers
in North America and Europe.
3. What tolerances can achieve?
Determining tolerances involves various factors, and there isn't a universal set that applies to all
processes and materials. The final tolerances on your part depend on factors such as part size,
design geometry, the number and size of features, material properties, surface finish, and the
chosen manufacturing process.
Upon order confirmation, we conduct a Design for Manufacturing review, highlighting areas that
may need modification for improved manufacturability. It is beneficial if you can specify critical
tolerance areas in your design, allowing for potential modifications to reduce production time and
costs.
We provide general tolerance guidelines for CNC machining in metal and plastic, plastic injection
molding, CNC metals and plastic injection molding materials, metal 3D printing (+/- 0.5mm),
and the expected shrinkage rate of +/- 0.15% for vacuum casting. All manufacturing and
technical specifications must be clearly outlined in the 2D drawings for accurate adherence.
4. How can I ensure my design is confidential?
We can sign the NDA (Non-disclosure Agreement) with our customers before quoting or placing
an order.
