Custom Service CNC Machining 316 Stainless Steel CNC Turning Lathe Part
CNC machining, short for computer numerical control machining, represents a subtractive
manufacturing method that relies on the coordination of computerized controls and machine tools.
This process involves the removal of layers from a solid material block, with programming guiding
the desired cuts in the metal. The corresponding tools and machinery then execute the machining
task in an automated fashion.
Product Details
The turning process predominantly employs metals as its primary materials.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
Nonetheless, this versatile process can also be applied to machine plastic components and work
with an array of other materials, including ceramics, composites, thermoplastics, and thermosets.
The Most Popular Materials | |

Stainless Steel 304 | Good strength-to-weight ratio, excellent machinability, low hardness |
Brass C360 | Excellent mechanical properties, resistant to corrosion & acid, relatively difficult to machine |
ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
Nylon (PA6 & PA66) | Excellent mechanical properties, high toughness, poor moisture resistance |
POM (Delrin) | 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.
CNC Turning 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. |

FAQ's
1. How much do CNC machining materials cost?
The multitude of materials available for CNC machining introduces a range of costs, influenced by
the unique properties and characteristics of each material. In the realm of metal parts, Aluminum
6061 is a standout for its economical pricing.
If cost efficiency is a priority, ABS takes the lead as the most budget-friendly option.
Importantly, the ease of machining is a key factor impacting costs. Stainless steel, known for its
hardness in comparison to aluminum, presents higher machining complexities, contributing to an
overall increase in costs.
