Other common tasks like how to cut tapers and how to turn an eccentric using an independent 4-jaw chuck are covered. Special segments on accessories include use of the steady rest, follower rest, live center, center drills and doing milling jobs on the lathe using either the vertical milling table or the more versatile vertical milling column.

The basics of using the threading attachment are also covered. You are also reminded at the appropriate times of proper safety procedures so you will learn to work safely. The video features helpful inset photos, screen-in-screen views and titles to help explain the more complicated aspects of some of the jobs. An initial menu screen allows you to watch the segments in any order you choose. By the time you are done watching this video even a person who has never used a lathe before will have the knowledge and confidence to chuck up a piece of metal and start making chips.

Though the Sherline Model lathe is used in all the examples, the techniques used here could be applied to any other Sherline lathe or, for that matter, any other brand of lathe. The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.

A special washer locates in on center in the spindle hole. It is held in place in the 1 Morse taper with the drawbolt.

Tommy Bars— Round steel bars used to tighten and loosen chucks and other spindle accessories. Y-axis Locking Screw— A thumbscrew on the side of the base that keeps the saddle from moving in and out when tightened. X-axis Locking Screw— A screw that goes through the barrel lock on the front of the saddle to lock the table in place during machining operations where movement is not required or desired. Backlash Locks— The lock works like tightening two nuts against each other on a threaded shaft to reduce play in the threads.

Backlash is the pause in travel when changing direction of rotation of any threaded crew. When you stop and change directions, the screw turns a slight amount while the thread picks up the other side and begins to move the nut in the other direction.

In essence, it is the amount you can turn the handwheel in the reverse direction before movement occurs on an axis.. An adjustment is provided on the X- and Y-axes to reduce the leadscrew backlash. You adjust to a known or acceptable amount using the locks and then remove it from the machining operation by always approaching your cut from the same direction with the backlash already eliminated before the cut begins. Alignment Key— A precision ground key that fits in a slot in the column saddle to keep the headstock aligned straight up and down.

Removing this key and rotating the headstock allows bevels to be cut at any angle. An approximate angle scale is laser engraved into the saddle for reference. Headstock Spacer Block— Moves the headstock 1. It is optional on series mills, standard on series mills and not needed on series mills because the ram can be used to adjust this distance. V-belt— A Kevlar-reinforced Urethane belt that drives the spindle through the pulleys. Rotary Column Attachment— This function allows the vertical column to be rotated from side to side to do angled milling or drilling.

They are laser engraved with 50 marks inch or marks metric and numbers for reference. Adjustable zero handwheels allow you to stop at any given point, loosen a knurled wheel in the center of the handwheel and rotate the laser engraved collar back to the zero mark before starting the next cut without moving the position of the handwheel. This means each time you are starting from zero rather than from a random number, making your depth and cut calculations easier.

This eventually means less mistakes. Digital readouts incorporate an electronic box with a screen that reads out numbers rather than looking at the graduations on the handwheels to determine movement. This helps eliminate a common source of errors. Any Sherline lathe or mill can be ordered fitted with DRO or it can be added later. Also incorporated in the readout is a sensor and RPM indicator for the spindle to eliminate guesswork regarding spindle speed.

Any Sherline machine can be ordered ready for the application of CNC or as a complete CNC system with steppers, controller, computer, software and everything. CNC can also be fitted at a later date to any Sherline lathe or mill. End Mills— They look like drill bits but are sharpened on the sides as well as the ends. Held in an end mill holder, they are used to cut slots, pockets or surfaces. End mills can have two, three or four flutes spiral cuts in the sides.

The part is moved under the cutter which puts a nice, flat surface on the part. Mill Vise— A small vise that is clamped to the mill table and holds parts for milling. It is different from the more common drill press vise in that it tightens with a pull-down function that helps hold the part down as well as in to counter the forces of milling.

It is also accurately machined so it can be aligned in the machine for accurate cuts. Hold-down Set— A series of adjustable clamps that are used to hold parts to the mill table for milling. They can be used on large or uneven parts like castings. Boring Head— Rotated in the headstock, the boring head holds a sharpened tool that rotates off center to scribe a circle. It is lowered into the bore of a hole to enlarge the hole to a given size.

A fine adjustment on the boring head allows the cutter to be moved out a little at a time to enlarge the circle of the cut. It is used when a very accurate hole is needed, like on the cylinder of an engine or when a large drill of the needed size is not available or practical. With the boring head you can make accurate holes up to 1. Chucks— A 3-jaw or 4-jaw chuck threads onto the spindle nose to hold your work, a drill chuck is used on the tailstock to center drill your part.
