The tailstock slides along the bedways and has a (generally) non-rotating spindle that is concentric with the main lathe spindle. The tailstock is generally used to support the end of long workpieces, or it can be fitted with a drill chuck to drilling and other holemaking operations.

The non-rotating tailstock spindle has a tapered hole that can be fitted with tooling such as live or dead centers, drill chucks or tapered tools. The spindle can be extended or retracted with the handwheel, or locked in place with the tailstock spindle lock. The tailstock spindle is typically graduated for rough positioning.

The lathe is a very versatile and important machine to know how to operate. This machine rotates a cylindrical object against a tool that the individual controls. The lathe is the forerunner of all machine tools. The work is held and rotated on its axis while the cutting tool is advanced along the line of a desired cut. The lathe is one of the most versatile machine tools used in industry. With suitable attachments, the lather may be used for turning, tapering, form turning, screw cutting, facing, dulling, boring, spinning, grinding, polishing operation. Cutting operations are performed with a cutting tool fed either parallel or at right angles to the axis of the work. The cutting tool may also be fed at an angle, relative to the axis of the work, for machining taper and angles. On a lathe, the tailstock does not rotate. Instead, the spindle that holds the stock rotates. Collets, centers, three jaw chucks, and other work-holding attachments can all be held in spindle. The tailstock can hold tools for drilling, threading, reaming, or cutting tapers. Additionally, it can support the end of the workpiece using a center and can be adjusted to adapt to different workpiece lengths.

It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined. A lathe center is mounted in the tailstock, and inserted against the sides of a hole in the center of the workpiece. A tailstock has a Dead Center, while a headstock has a Live Center. A Tailstock is particularly useful when the workpiece is relatively long and slender. Failing to use a tailstock can cause "chatter," where the workpiece bends excessively while being cut.

Usually, the entire tailstock is moved to the approximate position that it will be needed by manually sliding it along its ways. There, it is locked in place and the tool mounted to it is moved with a leadscrew to the exact position where it is needed. When a cutting tool such as a drill bit or reamer is used, the feed is done with this leadscrew. The extendible portion of the tailstock is called the barrel, and usually has a Morse taper mount in the end of it to secure the drill or reamer. If the work is heavy, the drill may be further secured from turning with a lathe dog as shown in the photo.

Riten Linear Compensating Live Centers represent the pinnacle of spring loaded live centers. The typical spring loaded live center has the rotating spindle sliding through the bearing assembly. The linear compensating live center has the entire bearing assembly (including the spindle) sliding inside the housing. Comparing a spring loaded live center to a linear compensating live center is like comparing the capacity and rigidity of a traditional live center to that of a heavy duty live tailstock.

Four sets of interechangeable, color coded die springs provide light, medium, heavy and extra heavy linear force. This self-contained model (shown) can be chucked and is especially suited for multi-function turning centers with sub-spindles and programmable tailstocks.

The automatic lubrication system adopts progressive distributor. According to the needs of different grease quantity of middle seat assembly, tailstock assembly and left and right crank pin assembly, the flow rate is 2:2:1. The total displacement is 3ml/min, the middle seat assembly is 1ml/min, the tailstock assembly is 1ml/min, the left and right crank pin assemblies are 0.5ml/min, and the lubrication is not uneven.

The assembly of the design so far consists of 5 main components: the heater block, the nozzle, the insulator, the filament sleeve and the mounting bracket. The heater block houses the resistor heating element and thermistor and also serves to clamp/hold the nozzle. The insulator thermally isolates the heater block from the extruder - it also keeps everything lined up. The mounting block holds everything securely against the extruder.

At this point I'm fairly satisfied with the print quality and speed. Other factors are now limiting the performance and I need to work on improving the frame design so that I can push the hot end to higher speeds without increasing vibration, etc. V0.6 will probably be reserved for improving integration with the extruder and refining some of the assembly/construction. be457b7860
