The real shot of aisi4340 cnc steel parts:
Popular science knowledge:
4340 steel is a medium carbon, low alloy steel known for its
toughness and strength. AISI 4340 is also a nickel chromium
molybdenum steel. In the tensile range of 930-1080MPa, 4340 alloy
steel and temper are usually supplied. Pre-hardened and tempered
4340 steel can be further case hardened by flame or induction
hardening and nitriding. 4340 steel has good impact and impact
resistance as well as wear and abrasion resistance in the hardened
condition. AISI 4340 steel properties provide good ductility in the
annealed condition, allowing it to be bent or formed. Our 4340
alloy steel can also be melted and resistance welded, other alloy
steels are not hardenable to provide the required strength. It's an
excellent choice for highly stressful sections.
The performance of 4340 steel during CNC machining :
CNC machining is best done with 4340 alloy steel in the annealed or
normalized and tempered condition. It can be easily machined by all
conventional methods such as sawing, turning, drilling etc.
However, under high strength conditions of 200ksi and above, its
machinability is only 25% to 10% of that under annealed conditions.
What industries is 4340 steel cnc part usually used in?
AISI 4340 steel is used in most industrial sectors for applications
requiring higher tensile/yield strength than 4140 steel. Some
typical applications such as:
- aircraft landing gear
- car,
- oil and gas drilling,
- forging,
- cold and warm molding,
- machine building,
- Transmission systems such as power transmission gears and shafts.
- General engineering industry and structural applications such as:
heavy shafts, gears, axles, spindles, co

What is 4-axis CNC milling?
CNC machining has grown to become one of the most critical
manufacturing processes used on workshops around the world. Adding
computer control to a previously manual process allowed a leap
forward in the accuracy and precision of machined parts.
Furthermore, due to the increasingly complex requirements of
various industries, CNC machine tools have undergone several
evolutions to better meet the needs of customers. The evolution of
CNC machining technology has given rise to various forms and
variations of the technology. These include 3-axis, 4-axis and
5-axis CNC machines.As a leading provider of CNC machining
services, we often receive questions from our customers about how
these machines work. This article will focus on the working
principles, advantages and applications of 4-axis CNC machining.
4-axis CNC milling working principle:
4-axis CNC machining offers a significant upgrade over 3-axis
machining. It adds an additional degree of freedom through
rotational motion, making machining complex features possible and
more straightforward.
In 4-axis CNC machining, the tool moves freely on the X, Y, and Z
axes to machine the workpiece. However, the workpiece is not
stationary on the table like in 3-axis machining.
A 4-axis CNC machine can rotate a workpiece around the X-axis in a
plane called the A-axis. So as the tool moves along the workpiece
and the table turns it, you can cut along the contour of the
workpiece.
Advantages of 4-axis CNC milling:
Higher design complexity can be achieved. Because the table rotates
around the X-axis, 4-axis CNC machines can produce intricately
detailed parts. Additionally, the extra rotation makes it possible
to access and machine parts on other faces at odd angles to create
the final part. High precision and accuracy. 4-axis CNC machines
can access multiple faces of a workpiece without adjusting or
changing fixtures. As a result, parts made from it are highly
accurate and meet strict standards. Higher speed and lower
production cost. Most jobs done on a 4-axis CNC machine require
only one setup. As a result, work can proceed smoothly without
downtime or intervention to change fixtures and tools.
