Experience and expertise
With a decade of experience in the machining business, and with comprehensive knowledge of material properties, we know how to handle even the most complex parts — no matter the medium.
From aerospace parts to high-tech electronic products, we’ve worked with companies all across the manufacturing spectrum.
5-axis machining is widely used in the automotive industry for the prototyping and production of car components.
These components include:
Although turnaround times may be a big concern for some aerospace companies, complexity is the main reason why the industry is so dependent on 5-axis CNC.
Aircraft components often have intricate geometries — frequently including curves and interior cuts — that would take a long time to machine on a 3-axis setup.
5-axis machining can be used on all manner of titanium and aluminum aerospace parts, including:
Titanium and stainless steel surgical tools are frequently fabricated with 5-axis machining. These parts must be made to a high level of precision and are often made in large quantities, which favors the increased efficiency of a 5-axis CNC machine.
Machined surgical tools include:
Large-scale 5-axis machine shops are frequently employed by governments for military projects, with 5-axis CNC suitable for the production of parts such as:
In the electronics industry, 5-axis machining can be used to make essential parts for consumer electronic devices such as digital cameras and laptops.
Electronics casings and enclosures are often machined from plastic or aluminum, and 5-axis CNC is especially useful for chassis of irregularly shaped devices such as SLR cameras.
5-axis machining can also be used to fabricate parts like heat sinks — especially those with irregular or densely populated fin patterns. The efficiency and deftness of 5-axis also makes it easy to fabricate heat sinks in large quantities.
5-axis CNC machining can be used to cut deep mold cavities with minimal tool chatter and maximum precision. This is because 5-axis provides much better tool access to the workpiece, which in turn allows shorter cutting tools to be used.
All of this makes 5-axis CNC an appealing alternative to EDM, which is a much slower moldmaking process than CNC machining.
5-axis machining is, as the name suggests, a form of CNC machining in which the cutting tool can move along five axes instead of the usual three.
So how does that work? Well, with a 3-axis CNC machine, the spindle moves up and down, side to side, back and forth. 5-axis machines, in addition to this 3-axis movement, have two further axes in play: either the table rocks side to side on two different axes or the spindle itself swivels on two axes.
Either of these methods (more on their differences later) allow the cutting tool to approach the workpiece from an infinitely greater number of angles, and this makes it possible to create highly complex shapes.
It also reduces the number of setups needed: machinists don’t have to manually turn the workpiece over, because the cutting tool can simply reach more places. And this makes the entire machining process much, much faster.
5-axis CNC machines can differ from one another in another important way. Some 5-axis machines use what is known as “simultaneous” 5-axis machining, while others employ a “3+2-axis” method.
Simultaneous (or continuous) 5-axis machining is a form of 5-axis machining in which the machine can continually adjust movement on all five axes without pause. Simultaneous 5-axis CNC can be very fast, since there are no breaks between passes of the cutting tool.
Another form of 5-axis machining is 3+2-axis, in which the machine can only move on the 4th and 5th axes (adjusting the angle of the cutting tool) when the cutting tool isn’t moving along the X, Y and Z axes. This form of 5-axis machining can be slower than simultaneous 5-axis CNC, but may result in more rigid parts and longer tool life.
5-axis CNC machines can have different configurations. All have spindles that travel along the X, Y and Z axes, but machines can add the two “extra” axes in different ways.
The most common types of 5-axis CNC machine are trunnion-style machines and swivel-rotate-style machines. Some machines combine features of both.
A trunnion-style CNC machine is a kind of CNC mill with a moving table. That means the angle of the workpiece attached to the table can be adjusted, allowing the cutting tool to hit the material from different angles.
Trunnion-style machines have an A-axis and C-axis, and their advantages include better undercut access, effective removal of heavy materials and a larger overall work volume.
A swivel-rotate-style CNC machine is a kind of CNC mill with a rotating spindle. Adding a B-axis and C-axis to the spindle allows the cutting tool to hit the material from different angles, but in a different manner to a trunnion machine.
Advantages of swivel-rotate-style 5-axis CNC machines include the ability to handle heavy parts, since the table remains stationary, and compatibility with much shorter cutting tools — effectively reducing chatter and increasing accuracy.
The axes, in terms of CNC machining, determine the number of directions that the cutting tool can move in when producing parts. There are the three-dimensional axes, and the 5-axis machine’s cutting tool can also rotate to approach the part from two directions, which serve as two additional axes.
Because of the flexibility offered by 5-axis machining, it should be used to create the most complex shapes and details in parts. The stability of the tool also provides a smoother and more consistent finish.
5-axis CNC machining is one of the most advanced manufacturing technologies available, so it can produce some of the tightest tolerances possible, even on complex and detailed parts.
