Machining center spindle BT40 and BT50 What is the difference?

Machining center spindle BT40 and BT50 What is the difference?

The spindle is an important part of the machining center, and the form of the spindle determines the speed and cutting force of a machining center. Commonly used machining spindle BT40 and BT50, many customers in the choice of BT40 spindle or BT50 spindle will hesitate, then what is the difference between the two?

Machining center spindle

Machining center with BT50, BT40, BT30 they have a common name called "tool handle", is the central link connecting the machining center spindle and the tool. The machining center has a large and small, can not be installed on a small machining center with a large tool, so at the time of design, the CNC machining center spindle is designed into three types in general, BT30,BT40,BT50, the size, length, taper between them are not the same. They are not interchangeable, that is, they are not universal. Suppose that the machine you are using is BT40, and after you buy the machining center of BT30, all the tools must be replaced.

Machining center BT50 and BT40 how to choose? The greater the shaft torque of the spindle of the machining center, the stronger the chip force will be, the larger the tool torque of the same material will be selected, the larger the cutting efficiency will be higher, and it is not easy to shake the knife. In this way, the machining accuracy will be guaranteed. A wider range of materials suitable for cutting. If the BT40 spindle processing BT50 process is selected, it will be like a calf pulling a big car, and the machining center will have a great vibration when it is used, so that the accuracy and life of the machining center will not be guaranteed. If the cutting force is large and the torque is required, the BT50 spindle should be selected.

Of course, the specific type of spindle selected by the machining center depends on the size of the cutting force requirements of the workpiece processed.
