Home > Multiple Spindle head deviceModel D-264; D-306; D-318
Feature:- This type of stone drilling machine spindle head is an adjustable 4 spindle head.
- This type of spindle head of tapping and drilling machine is suitable for Large distance requirement.
- JT taper chuck could be used in this type.
- High speed R.P.M. It is used for drilling function only, special working for wood material.
- D-315 is a reverse design of 4 spindle head, it can not be used on gear type machine.
- D-type adjustable multi-spindle is not capable of adjusting linear four-axis machining. For linear processing, please refer to the U-type.
- In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it such as chuck.
- A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles. These are called multispindle machines.
