However, if it is in prototype development, it is only a small part of the runtime, and for setting the time, it is the extra time that is irrelevant. And what’s the most relevant? The most relevant is the cost savings that the design provides.
Obviously, in a short period of time, both the precision of the machine and production machine, they are the same important, but in a short period of time, not important spindle power, speed, and the demand of the automatic tool change.
On light machines, we need to achieve precision. What kind of milling machine is considered too light? In general, we believe that the weight of any of the milling machines below 5,000 pounds is very light. If you want to achieve precision, you can implement it with a lightweight machine, but some of the necessary features must be remembered. Dynamic stiffness is one of the most important considerations.
The ability of a machine to resist external forces when moving is dynamic stiffness. What determines the degree of dynamic stiffness of a machine? Generally, it depends on a number of factors: speed, inertia, static stiffness, and damping, for example. For example, you can imagine a quarter of a diameter rod round head; At this point, imagine trying to push that blunt bar over an empty aluminum can. You can make some sounds in the process and crunch as you can get through the can. Now, we use the same aluminum can, place it on the fence post, then shoot it and shoot it with a 22-caliber bullet. At this point, you get a hole, and the hole is a clean, unreformed hole. We all know that the force is sometimes weaker than the static force, but it’s not the same as the dynamic force, and it gets very hard. The result of dynamic stiffness is cleaner cutting.
