What is aisi4340 steel?

Chinese brand 40CRNIMO round stick
For reference, corresponding steel number:
China GB steel number: 40CrNi2MoA, German DIN steel number 36CrNiMo4, German DIN material number 1.6511, French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American AISI/ASTM4340, American UNS standard G43400
Features:
It has high strength, toughness and outstanding hardenability and stability against overheating, but it has high sensitivity to white spots and tempering brittleness. Weldability is poor, before welding need to be preheated by high temperature, after welding need to eliminate stress, after tempering use.
Heat treatment:
(Quenching 850 degrees; Coolant: oil; Tempering temperature 600 degrees; Coolant: water, oil);
Steel annealing or high temperature tempering supply state Brinell hardness HBW is less than or equal to 269;
Purpose:
It is used for important tempering parts requiring good toughness, high strength, and large size, such as heavy machinery shaft with high load, turbine shaft with diameter greater than 250mm, helicopter rotor shaft, turbojet engine turboshaft, blade, high-load transmission parts, crankshaft fasteners. Gear, etc. It can also be used for rotor shaft and blade whose operating temperature exceeds 400℃. It can also be nitriding treatment, used to make important parts with special performance requirements, and can be used as ultra-high strength steel after low temperature tempering or isothermal quenching.

How CNC milling works

Like other machining processes, CNC milling begins with designers creating a digital part using CAD (Computer-aided Design) software. The file is then converted into “G-Code,” which can be recognized by a CNC mill.

CNC mills have a “worktable” and work holding device to keep a block of material — known as the “workpiece” — in place. The worktable may or may not move, depending on the style of the machine.

During the CNC milling process, the rapidly rotating cutting tool makes contact with the workpiece, cutting away material. The tool moves according to the G-Code instructions so that cuts are made in the right places until the part is finished. Some CNC mills use moving worktables to create a greater number of cutting angles.

CNC mills can cut through hard metals. This makes them more versatile than CNC routers, which are similar to 3-axis mills but less capable of penetrating hard materials.

CNC mills are different to CNC lathes or turning centers, where the workpiece rotates rather than the cutting tool.

Hi-Precision owns high precision 3-, 4- and 5-axis imported machines which allow us to achieve tight tolerances. We have also invested in a material tester, so that we can verify the materials we use and make sure they are the correct ones for each project. And we can quickly get measurement results from our automotive coordinate measuring machine (CMM).
