立式玻璃钻铣机的紧固装置，是一个非常重要的组成部分，它的质量将直接影响机床的正常使用中后期，一般适用于立式玻璃钻铣机的高新夹紧机构，加工精度高，工件上的收紧和放松状态一般可分为三类。工件通常处于匆忙状态，直到施加外力为止才被释放。
The fastening device of vertical glass drilling and milling machine is a very important part. Its quality will directly affect the normal use of the machine tool in the middle and later stages. It is generally suitable for the high-tech clamping mechanism of vertical glass drilling and milling machine with high machining precision. The tightening and loosening state on the workpiece can be generally divided into three categories. The workpiece is usually in a hurry and is not released until an external force is applied.
这种夹紧机构较常用于弹簧、液压释放，中间传动部分常用增力机构。这种夹紧机构的特点是能够在整个拧紧过程中可靠地保证夹紧力，而不会因断电等不可预见的情况而发生事故。

This clamping mechanism is often used for spring and hydraulic release, and the force increasing mechanism is commonly used in the middle transmission part. The characteristic of this clamping mechanism is that it can reliably ensure the clamping force in the whole tightening process without accidents due to unforeseen circumstances such as power failure.

工件往往处于松动状态，只有在外力增加时才会加大力度：这种夹紧机构经常使用一些力不太强的弹簧，当去掉夹紧力时，能更好地松开工件。它具有结构简单、调整方便等优点，是立式数控铣床的主要加工设备。但缺点是你一定一直保持动力，一旦你停电了，很容易引起事故。
The workpiece is often in a loose state, and the force will be increased only when the external force increases: this clamping mechanism often uses some springs with less force, which can better loosen the workpiece when the clamping force is removed. It has the advantages of simple structure and convenient adjustment. It is the main processing equipment of Vertical NC milling machine. But the disadvantage is that you must always keep driving. Once you lose power, it is easy to cause accidents.
无论是工件的紧固还是工件的释放都需要施加外力，在动力装置的传动机构和原材料的强化之间需要增加自锁机构。这种夹紧机构是一种更有用的夹紧机构。它适用于立式数控铣床加工高精度工件，但其缺点是设计结构相对复杂，不易广泛使用。
Whether the workpiece is fastened or released, external force needs to be applied, and a self-locking mechanism needs to be added between the transmission mechanism of the power device and the reinforcement of raw materials. This clamping mechanism is a more useful clamping mechanism. It is suitable for machining high-precision workpiece with Vertical NC milling machine, but its disadvantage is that the design structure is relatively complex and not easy to be widely used.
对立式玻璃钻铣机的紧固装置的知识，让我们来看看应该怎样选择夹紧点，选择合适的夹紧机构是立式数控铣床和加工效率起着重要的作用，所以在选择的过程中，用户要特别注意应尽可能用少的力量，发挥大的紧缩效应，避免工件出现滑动和旋转。另外，当你选择拧紧零件时，要确保你有足够的刚度，这样工件不会被变形损坏。
For the knowledge of the fastening device of the vertical glass drilling and milling machine, let's see how to select the clamping point. Selecting the appropriate clamping mechanism plays an important role in the vertical CNC milling machine and processing efficiency. Therefore, in the selection process, users should pay special attention to using less force as possible to give play to the large tightening effect and avoid the sliding and rotation of the workpiece. In addition, when you choose to tighten parts, make sure you have enough stiffness so that the workpiece will not be deformed and damaged.
