Our Pennsylvania facility contains multiple advanced vertical 5-axis machining centers capable of performing precision milling and machining of complex parts.
WHAT IS 5-AXIS MACHINING & MILLING?
Milling is the process of cutting and drilling material using a rotating cylindrical tool. This tool is held in a spindle and comes in a variety of sizes and forms. With 5-axis machining, there are two extra rotary axes defined by A, which rotates around the X axis, B, which rotates around the Y axis, and C, which rotates around the Z axis. The combination of additional axes depends on the machine and comes in variations, including AB, AC, or BC.
With 5-axis machining, the table or cutting tool can be tilted, creating the ability to avoid collision with the tool holder and allowing for better access to part geometry. This also ensures improved tool life and cycle time as it helps maintain cutting position and constant chip load. This type of machining offers a push toward single-setup machining, creating shorter lead times and increasing efficiency.
ADVANTAGES OF 5-AXIS VS. 3-AXIS MACHINING
While 3-axis machining has its benefits, it poses certain manufacturing limitations. The primary difference is that 5-axis machining introduces the element of rotation of the A and B axes, allowing for the quick production of more complex shapes with higher quality surface finishes. Other important 5-axis CNC machining benefits include:
- Shorter lead times. The enhanced capabilities of 5-axis machines result in decreased production times, which translate into shorter lead times for your production projects.
- Greater accuracy and tool life. 5-axis machining and milling offers a level of precision that 3-axis processes cannot replicate, which is crucial if your finished products must adhere to strict quality and performance specifications. 5-axis machining also eliminates the need to move the workpiece among multiple workstations, thereby reducing the risk of error.
- Use of shorter cutting tools. Producing high-quality 5-axis machined parts with the use of shorter cutters reduces vibration that frequently occurs when machining deep cavities with a 3-axis process. The use of a shorter cutting tool also allows for a higher cutting speed without putting excess pressure on the tool.
