Product Specification

Machining centers produce products from bar stock using up to 12 axes of motion. Our multi-tasking machine tools create cost-efficient small parts in both large and small volumes. CAD/CAM capability - Many parts of the milling production process, from the creation of tooling to the finished output of our CNC machining centers, Versatility - The portfolio of CNC milling services includes components made of many CNC material types; including stainless steel, aluminum, titanium, brass, and other metals and plastics, to meet the specialized needs of customers, aerospace, automotive, medical, appliance, food/beverage and more.Main Standards for Automotive Steel Components: The steel materials used for automotive components in the automotive industry mainly involve carbon structural steel, alloy steel, free-cutting steel, spring steel, non-quenched and tempered steel, bearing steel, gear steel, cold heading steel, heat-resistant steel, etc. Non-quenched and tempered steel is named as such because it does not require quenching and tempering treatment to achieve mechanical properties equivalent to those obtained through quenching and tempering treatment. Its characteristic is that it can achieve mechanical performance equivalent to quenching and tempering treatment without undergoing the treatment. Non-quenched and tempered steel is used in the manufacture of engine connecting rods, crankshafts, front axles, universal joint forks, wheel hubs, and other components for commercial vehicles.


1. Component: It is the basic manufacturing unit of an automobile and cannot be disassembled. Examples include piston rings, pistons, valves, etc.

2. Assembly: It is a combination of two or more components that function as a single component. Examples include a connecting rod with a cover, paired bearing shells, cylinder heads with valve guides, etc. The name of the assembly is determined by its main component.

3. Subassembly: It is an assembly of several components or assemblies that cannot independently perform the function of a specific mechanism. Examples include transmission covers, radiator covers, automotive steering connectors, etc. They are sometimes referred to as "semi-finished assemblies."

Module: It is a combination of several components, assemblies, and subassemblies that are integrated to perform a specific function independently. Examples include engine modules, clutch assemblies, and transmission assemblies.

4. Body panels: These are components made by stamping and welding sheet metal, which cover the body of the vehicle. Examples include radiator grilles, fenders, etc.


Material: Steel 1045 Machined Parts

Cox Manufacturing has a reputation for machining quality parts from 1045 Steel. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.

Steel alloy 1045 is a versatile medium carbon alloy, ideal for parts that require strength and impact resistance. Due to its higher carbon content, it has higher tensile strength. 1045 has excellent ductility and toughness.1045 has a machining cost factor of 3.0 when compared to steel 12L14. It is not ideal for welding or forming due to its higher carbon content. 1045 responds to heat treatment extremely well, but it is not ideal for case hardening.

Product Packaging
