Milling Machine Applications
- Precision surfacing, drilling, and slotting for custom part prototyping and small-batch production.
- Versatile angled machining utilizing the articulating head, which can be tilted left or right to accommodate complex contours.
- Consistent downfeed boring utilizing the large chromed quill with .0015", .003", and .006" IPR rates.
- Reliable toolroom maintenance tasks where rigid dovetailed ways are necessary to prevent chatter.
Finding a jet 7-7-8 x 35-3-4 knee milling machine 690038 for sale guarantees your shop is equipped with a versatile, safety-conscious workhorse engineered for daily, rigorous manual machining.
