What is another defect of the kneecap? That is the difficulty of managing chips and coolants. Usually, do you know what the fpc6 operation usually has? It is generally limited to cleaning the surface, drilling a hole pattern, or cutting into a size contour that allows it to operate even on a small chip brush. Eventually, most of the stock turns into a chip that is usually fpc1; We have to cut a hard piece of metal and we need to cut a shape, which is the same as Michelangelo’s sculpture from a piece of marble. At this point, chips and coolants will fly around. If the frame is mounted on a bridge knee, it is very difficult to stop.
In fpc1, bed mill is more common. This is compared to the knee movement when the whole head is moved, and if there is an obvious Z movement, it is relatively cheap. Comparing with the goose feather movement, the stiffness of the machine frame needs to be moved to the head design, while good motion range is also allowed. The strength of the high knee motion is eliminated by a moving head of bed design, and a larger range is allowed, not just movement.
We interviewed a lot of mechanics when fpc1 was designed by us. For example, in many beds below 10,000 pounds, they have a computer-controlled z-axis movement on the entire head and the manual z-axis movement on a feather pen. Manual feather pen operation is very similar to drill bed. Most users tell us that quill (the hardest location) is taken back by them, and it’s locked up, but it’s never been moved. Since the use of manual feather pens seems to be unusual, we don’t think it’s necessary and have made a decision to stop providing the extra z-axis. This decision is very useful, its detailed design result is very inspiring: now, the machined surface becomes less, rack and pinion also have no, the head of the division.
