Operating as a subtractive manufacturing process, CNC machining involves the creation of parts by
removing material from a workpiece or workpiece stock. The machine's movement is governed by
preprogrammed software and codes, ensuring precise control over material removal.
This expansive process includes a diverse range of machinery, such as turning mills, lathes, grinders,
and plasma-cutting machines.
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. |

FAQ's
1. The cost of CNC machining a part depends on a range of factors, some of which are
listed below:
1. Material: The choice of material impacts costs, with some materials, like aluminum, being more
cost-effective to machine than others such as Inconel, due to considerations like tool wear and
cutting speeds.
2. Complexity: Parts with intricate features tend to be more expensive to machine.
The complexity of surface shapes, for example, directly influences machining costs.
3. Tolerances: Tighter dimensional tolerances increase the cost of CNC machining. It's crucial to
balance precision requirements with cost considerations to optimize overall expenses.
4. Surface Finish: Attaining mirror finishes necessitates specialized tools and machining strategies,
contributing to increased machining time and associated costs.
5. Quantity: The production volume plays a significant role in cost considerations. Low-volume
production tends to be more expensive per part, as initial setup and programming costs are
amortized over a smaller number of parts.
2. What are your tolerances for machined parts?
Our standards for machined parts encompass +.005”/- .005” local tolerances across most metal
geometries and +/- 0.010" for plastics. Notably, these tolerances may vary for larger parts,
particularly concerning flatness after heat treatment.
Achieving an "As Milled" finish for CNC parts necessitates a minimum surface finish of 125.
Fabricated parts adhere to a 0.010” dimensional tolerance and a 1° angular tolerance.
Tapped holes not explicitly marked as features in the CAD model may be machined according to
the specified diameters.
Importantly, surface treatments, including anodization, bead blasting, iriditing, powder coating, etc.,
will only be applied if explicitly paid for and acknowledged.
3. How quickly can I get my parts?
With complete 2D and 3D CAD models, we can manufacture quality parts in just two weeks.
However, for more complex parts with special features, additional time may be required.
