The cutting angles are adjustable through the machine’s control interface, allowing you to optimize the blade position for various materials.
The working table features a flat surface with vacuum zones or clamp systems to secure your materials during cutting operations. It’s designed to withstand vibration while maintaining dimensional stability.
The Science Behind Oscillating Motion
While the term “oscillation” might sound complex, it simply describes the blade’s repetitive back-and-forth motion that occurs at precise frequencies. When you examine the oscillating mechanics, you’ll notice that the blade moves through a controlled stroke length while maintaining consistent speed and force throughout each cycle.
| Parameter | Effect | Application |
