Effective Method of Choosing Correct Spring Clamp ER collet
October 09, 2019
ER spring chuck system has been widely used in machine tools all over the world due to its good scalability and accuracy.
As a daily tool, how to choose and install each component correctly is very important. However, whether you are a senior engineer or a novice, you may think more than once about the question, "Is the right chuck I use?"
Indeed, different sizes and forms of chucks often cause some problems when people use them. Under what circumstances can we know that the selected chucks are suitable? Today we will raise the position of "chucks" for you.
Spring chuck
First, how do you know the size of the ER blade you use?
It can be obtained by simply measuring the inner hole of the cutter head. For example, the measurement result in the figure above is 32mm, so this is an er32 cutter head.
We need to choose the corresponding spring chuck according to the different cutter heads.
It's the basic type of chuck. Choose high precision or low cost according to your needs.
I chose the second one, which has a small jump. Can my knife fit in?
ER32 chuck can hold 20MM tool handle, and my tool can just fit in.
With chucks, how to choose nuts?
High speed dynamic milling, so my second, low friction nut.
When we are ready, we need to set it according to the corresponding technical parameters.
With that, we can be ready to start working.
