Way Systems
The way system is the part of the machine tool that holds linear motion on track in each axis. There are two basic types:
- Box ways, or “hardened ground ways.” This is the conventional approach. A box-shaped stationary way mates with a slide. A thin film of oil is pumped between them to keep the slide moving.
- Linear guides. Many newer machining centers use this system. A linear bearing rolls along a guideway. This guideway is usually profiled in some way to help the bearing grip it.
Most machining centers designed for HSM use linear guides. The choice offers
strengths and tradeoffs.
A third approach used by non-standard machines might be described as virtual ways.
