Dead center (the conical piece) mounted in the spindle of a lathe and being used to support a workpiece being driven by a carrier setup. A lathe center, often shortened to center, is a tool that has been ground to a point to accurately position a workpiece on an axis. They usually have an included angle of 60°, but in heavy machining ...
Spindle nose on a lathe headstock. The small female taper is a Morse taper to take a lathe center or a tool such as a twist drill. The large male taper takes a lathe chuck, which is retained by the large nut. A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool.
The wood rotates between the headstock of the lathe which includes the drive mechanism and the tailstock support, which only rotates if its center is 'live' or supported by a rotating holding device. The headstock end may use points or spurs which are driven into the wood. This type of turning is described as 'between centers.'
A tailstock, also known as a foot stock, [1] is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined.
A backplate with a female (self-releasing) taper may seat on the matching male taper of the tapered spindle nose (for lathe work) or of an adapter plate with the same nose, to be mounted on a table. This system improves the repeatability of the mounting concentricity down to a very small total indicated runout (TIR) value. Subtypes:
The introduction of CNC-controlled lathes has provided a practical, everyday solution via automated CSS Machining Process Monitoring and Control. By means of the machine's software and variable speed electric motors, the lathe can increase the RPM of the spindle as the cutter gets closer to the center of the part.
