Having changed over the years, the names given to various parts of the lathe are still not completely standardised. No doubt when the government has finished organising every other aspect of our lives it will appoint a highly-paid commission to look into the matter and make "recommendations". If you would like to buy a book or CD to extend clausing 1500 lathe manual knowledge of lathes - and how to operate them - look here.

Illustrations clausing 1500 lathe manual the parts discussed can be found by following the various hyperlinks and clausing 1500 lathe manual at the bottom of this page. It may be that an Instruction Manual, an Illustrated Parts Book or informative sales Literature may be available for your lathe: It's still sometimes possible to see advertisements that refer to certain capabilities: The surfaces of the bed that are finely machined - and upon which the carriage and tailstock slide - are known as "ways".

Some beds have a gap near the headstock to allow extra-large diameters to be turned. Sometimes the gap is formed by the machined ways stopping short of the headstock, sometimes by a piece of bed that can be unbolted, removed--and lost. Some very large lathes have a " sliding bed " where the upper part, on which the carriage and tailstock sit, can be slid along a separate lower part s albert font mac and so make the gap correspondingly larger or smaller.

SADDLE The casting that fits onto the top of the bed and slides along it is known, almost universally, as the "Saddle" - a self-explanatory and very suitable term. APRON The clausing 1500 lathe manual, often flat and rectangular "plate" fastened to the front of the "Saddle" and hanging down in front of itm is known as the "Apron" and carries a selection of gears and controls that allow the carriage to be driven by hand or power up and down the bed. The mechanism inside can also engage the screwcutting feed and various powered tool feeds, should they be fitted.

The leadscrew, and sometimes a power shaft as well, are often arranged to pass through the apron and provide it with a drive for the various functions. The sophistication of the apron-mounted controls, and their ease of use, is a reliable indicator clausing 1500 lathe manual the quality of a lathe. Virtually all screw-cutting lathes have what is commonly-called a "half-nut" lever that closes down one and sometimes two halves of a split nut to grasp the leadscrew and provide a drive for screwcutting.

Apron design can be roughly divided into "single-wall" and "double-wall" types. The "single-wall" apron has just one thickness of metal and, protruding from it and unsupported on their outer ends are studs that carry gears. The "double-wall" apron is a much more robust structure, rather like a narrow, open-topped box with the gear-carrying studs fitted between the two walls - and hence rigidly supported at both ends.

This type of construction produces a very stiff structure - and one that is far less likely to deflect under heavy-duty work; another advantage is that the closed base of the "box" can be used to house an oil reservoir the lubricant ion which is either splashed around or, preferably, pumped to supply the spindles, gears and even, on some lathes, the sliding surfaces of the bed and cross slide as well.

Very early lathes had a simple T-shaped piece of metal against which the turner "rested" his tool clausing 1500 lathe manual turning being done by hand but when it became possible to move this "Rest" across the bed by a screw feed it became known, appropriately enough, as a "Slide-rest".

The earliest known example of a "Slide-rest" is illustrated in Mittelalterliche Hausbuch, clausing 1500 lathe manual German publication of about After the "Top Slide" became a more common fitting the term "Slide-rest" was not so frequently used - and the different functions of the two slides led to their specific names being more widely adopted. When two slides are provided or sometimes, on watchmaker's lathes, three the complete assembly is known as the "Compound" or "Compound Slide" or even "Compound Slide-rest".

Some makers have been known to label the "Top Slide" as the "Compound Rest" or even the "Compound Slide" - but as " to compound " means the 'joining of two or more' - clausing 1500 lathe manual 'one' - this use of the term in incorrect. Some American publications even makers' handbooks have been known to casually refer to this as the "Saddle" - but this incorrect.

The lathe Headstock used, at one time, to be called the "Fixed Headstock" or "Fixed Head", and the rotating shaft within it the "Mandrel". Today the mandrel is usually called the "Spindle", but this can cause confusion with the tailstock, where the sliding bar is known variously as the "ram", "barrel" - and "spindle".

The headstock is normally mounted rigidly to the bed exceptions exist in some production, Clausing 1500 lathe manual, automatic and "Swiss-auto" types and holds all the clausing 1500 lathe manual, including various kinds and combinations clausing 1500 lathe manual pulleys or gears, so that the spindle can be made to turn at different speeds.

In turn, these attachments hold the workpiece that is going to be machined. The " fitting " formed on the end of the spindle is normally one of five types: This is a secure method, and allows high-speed reverse, but is very inconvenient on a general-purpose lathe. This is perfectly acceptable for smaller lathes, but unsatisfactory on larger industrial machines where, for reasons of production economy, the spindle may need to be reversed at high speed. Reversing a screwed-on chuck causes donna leon reichs erbe youtube to unscrew - with potentially disastrous results.

An ideal system for the rigid mounting of heavier chucks, it has now largely fallen into disuse. The fitting was available in various sizes starting at L00 L zero zero and worked up through L0, L1, L2, etc. All these succeeded in doing was to raise manufacturing costs by preventing the interchange of spindle-nose fringe season 2 episode 20 between machines and requiring firms to keep larger inventories of spares and numbers of duplicated fittings.

Some of these efforts included: Unbelievably, there appears never to have been a French standard - and we still await an official announcement of the rumoured Botswana-Standard Triple-cam with Over-locking Nose and Chinese-designed New Moon Slide-and-Snap-Approximately fittings. BACKGEAR As its name implies, "backgear" is a gear mounted at the back of the headstock although in practice it is often located in other positions that allows the chuck to rotate slowly with greatly-increased torque turning power.

At first, the ability to run a workpiece slowly might seem unnecessary, but a large-diameter casting, fastened to the faceplate and run at rpm about the slowest speed normally available on a lathe without backgear would have a linear speed at its outer edge beyond clausing 1500 lathe manual turning capacity of a clausing 1500 lathe manual lathe.

By engaging backgear, and so reducing the speed but increasing clausing 1500 lathe manual torque, even the largest faceplate-mounted jobs can be turned successfully. Screwcutting also requires slow speeds, typically between 25 and 50 rpm - especially if the operator is a beginner, or the job tricky.

A bottom speed in excess of those figures as usually found on most Far Eastern and European machines but not those built in the United Kingdom means that screwcutting jubiaba geronimo games especially internally, into blind holes - is, in effect, impossible.

These lathes are advertised as "screwcutting" but what that means in reality is just power feed along the bed. Even if you go to the trouble of making up a pulley system to reduce the spindle speeds you will find the torque needed to turn large diameters at low speeds causes the belts to slip. The only solution is a gear-driven low speed and so a proper small lathe, with a backgear fitted, not only becomes capable of cutting threads but can also tackle heavy-duty drilling, big-hole boring and large-diameter facing: Beginners are sometimes confused about how to engage backgear - especially if the lathe lacks a handbook - but with a little care anyone can work out how it should be done, at least on a conventional machine.

On the main spindle of the lathe, the one carrying the drive pulley, will be found a large gear, generally referred to as the "Bull Wheel". The Bull Wheel is attached to the pulley by a nut clausing 1500 lathe manual bolt, a spring-loaded pin, a pawl that presses into a gear on the pulley or some other clausing 1500 lathe manual and, if this fastening is undone - by clausing 1500 lathe manual the nut and pushing it towards the pulley, or by pulling the pin out - it should be found that the pulley will spin freely on the shaft.

By moving the "backgears" into position - they generally slide sideways, or are mounted on clausing 1500 lathe manual eccentric pin - the mechanism will come into operation. If the pulley will not spin on the shaft, or there seems to be no obvious way of disconnecting the Bull Wheel from the pulley, it may be that you are dealing with an "over-engineered" machine where some clever device has been introduced to make life "easy" for the operator.

Sometimes there will be a screw, flush with the surface of the drive pulley and beneath this a spring-loaded pin that pushes into the back face of the Bull Wheel. Quick-action "Sliding-cam" mechanisms are occasionally used as on the Drummond and Myford M Series lathes where a knob on the face of the Bull Wheel has to be pushed sideways, and so ride up a ramp, which action disengages the connecting pin automatically.

Some lathes, with enclosed headstocks like later Boxford models have a "single-lever" backgear; in this system moving the first part of the lever's movement disengages the connection whilst the next brings the backgear into mesh. LEADSCREW Originally termed a "master thread", or described as the "leading screw", but now always referred to as the "leadscrew", this is a long threaded rod normally found running along the front of the bed or, on some early examples running between the bed ways down the bed's centre line.

The unit is arranged to slide along the bed and can be locked to it at any convenient point; the upper portion of the unit is fitted with what is variously called a "barrel", "spindle" "ram" or "shoot" that can be moved in and out of the main clausing 1500 lathe manual by hand, lever or screw feed and carries a "Dead Centre" that supports the other end of work held by various means clausing 1500 lathe manual the headstock.

Special centres, which rotate with the work, can be used in the tailstock ; these are known as "Rotating Centres" and should not be referred to as "live centres" - that term being reserved for the centre carried in the headstock spindle. Long ago centres were referred to by turners as "Poppets" - presumably from "pop it in" - and they carried their own with them, secured in cotton waste and jealously guarded in the top pocket of their overalls.

In a typical arrangement, illustrated herethe motor is fastened to an upright, hinged, cast-iron plate and fitted with a small pulley on its spindle. Because the rpm motor is driving a much larger pulley in a ratio of something like 5: On the same shaft as the very large pulley is a set of three smaller pulleys, arranged in the "reverse" clausing 1500 lathe manual from those on the lathe. If the middle pulley on the countershaft is made to drive the identically-sized pulley on the lathe spindle that too, of course, will turn at rpm.

The pulleys each side of it are normally arranged to halve and double that speed - hence the creation of a speed set covering a useful rpm, rpm and rpm. It is a simple matter to fit both a small and a large pulleys to the motor shaft, and two correspondingly larger pulleys on the countershaft, and so double the number of available speeds to six.

If a two-speed electric motor is used the range doubles again to 12 and, should the lathe designer have managed to squeeze a four-step pulley between the spindle bearings, a total of 16 would be available; with a backgear fitted the total would rise to thirty-two speeds that, typically, might start at 25 r. They are normally contained within a cover at the extreme left-hand side of the lathe - but many older lathes, built in times when manufacturers were not concerned with saving people from their own carelessness, left them exposed.

Called "changewheels" because of the necessity to change them every time a different thread, or rate of tool feed, was required, the expression goes back to the earliest time that gears were used for this purpose. The gear train is usually carried on a quadrant arm able to be adjusted by being swung on its mounting to allow the mesh of the topmost gear with the output gear on the spindle or tumble reverse mechanism to be set.

In Great Britain the arm is sometimes called the "Banjo" - although this expression should really be limited to those types with just one slot. Some manufacturers, to make life difficult for themselves and their customers, tried other systems as well. A drive through changewheels often incorporates a tumble-reverse mechanism by which means the drive to the leadscrew clausing 1500 lathe manual be instantly reversed - and clausing 1500 lathe manual the cutting tool made to move towards or away from the headstock at will.

In its "neutral" position it also allows the headstock spindle to rotate freely and quietly without having to drive the screwcutting changewheels and leadscrew.

I have a clausing variable speed lathe I want to run on a vfd. I have read many threads on here but haven't found one that's simular to what I am doingprobably is one just haven't found it. So instead of hijacking someone's thread I'm starting my own. The variable speed is completely hydrolic no electrical and the the brake lever is connected to a friction clutch that stops the spindle and the motor keeps turning. If I wire the vfd straight to the motor then wire the forward,stop,reverse switch to the vfd I can still use my hydrolic veriable speed control that's on the lathe and the brake lever without harming the clausing 1500 lathe manual right?

All the threads on here I've found have to do with variable speed and lever or foot brakes that are electric diffference being mine are not. Here are clausing 1500 lathe manual manual pages about the wiring harenessvariable speedand brake lever. Attached Thumbnails. Yes, you can do it exactly as you describe. That lathe is a very simple clausing 1500 lathe manual for a drive because of it's clutched and brake headstock. I ran one exactly like that at work for many years.

I suspect that once you have the VFD setup, you'll find that it's much more convenient to adjust speed with the VFD, than to mess with the hydraulic vari-belt system You'll also find that a VFD's dynamic braking operation and reversing is much smoother. Set the vari-belt to a fairly low range, and program the VFD to go to about hz, and you'll find you never lack low-end torque, or an upper end speed limitation. Join Date Jun Location Near: I have the same machine s. My intent is to do the same.

The drive is simple to remove from clausing 1500 lathe manual machine so one of my thoughts has been to remove the Reeves components and replace with fixed belts. However I like the idea of simply setting the drive as Dave says above. As to reverse just use the drive controls for reverse. The drive shouldn't Plug if the designers have their ducks in the proverbial row. Bookmarks Unternehmen capricorn movies Digg del.
