It is a sliding unit on the bed-ways of the lathe bed.

It is situated on the right hand side of the lathe. It can be slide over the bed and clamped in any position on the bed by means of the clamping unit. The body of the tailstock is assembled to the base and has a corresponding longitudinal movement as to that of the base, along the bed.
It has a limited transverse movement as well, with respect to the base. Graduations are marked on the rear end of the base and a zero line is marked on the body. When both zero lines coincide the axis of the tailstock is in line with the axis of the headstock. The carriage is the part of the lathe which slides over the bed-ways between the headstock and the tail stock.
It provides various movements for the cutting tool manually as well as by power feed.

The carriage can be locked on the bed at any desired position by tightening the carriage lock-screw. The tool is provided with the following three movements by the carriage. Cross-feed — with the help of the cross-slide movement perpendicular to the axis of the work.
The bottom of the cross-slide has got a dovetail groove machined, which corresponds to the external dovetail machined on the saddle. The cross-slide is assembled to the saddle with the help of a tapered jib. The adjustment of the jib facilitates the required fit for the movement of the cross-slide on the saddle.
The cross-slide functions perpendicular to the lathe axis either by hand feed or by automatic feed. A left hand square or acme thread screw-rod fitted with a hand wheel helps in the manual movement of the cross-slide.
The automatic feeding is achieved through gearing. A graduated collar mounted on the screw-rod along with the hand wheel helps to set the fine, movements of the cross slide. The head of the bolts moves in the T slot groove on the top of the cross-slide. The swivel base is provided with a dovetail on its top surface and the top slide has a corresponding dovetail groove.
The assembly of the top slide to the swivel base is done by a tapered jib which can be adjusted to control the top slide movement. The sliding of the top slide on the swivel base is accomplished by the help of a screw-rod fitted with a hand wheel and a graduated collar.
Only manual operation is possible for the top slide. The top slide assists in feeding the tool to the work. In the majority of cases, the bed generally, a single iron casting. In larger machines, the bed may be in two or more sections, accurately assembled together.
Web bracings are often employed to increase the rigidity. For absorbing shock and vibration, the bed should be of considerable weight. A swarf or a combined swarf and a coolant tray are provided on the lathes. This may be an integral part with the lathe bed. This increases the rigidity of the bed.
The bed generally rests on cast iron or welded sheet metal legs of box section. This provides the necessary working height for the lathe. Very often the electrical switch gear unit and the coolant pump assembly are housed in the box section legs at the headstock end.Privacy Terms.

This is the first time I've had it disassembled and I found the factory had put a glob of grease near the bronze leadscrew nut yet there is a Gitz type oil hole cover for lubricating the leadscrew on the cross slide above the leadscrew.
My question is are the grease and oil combination the proper type of lubricant for the cross slide leadscrew or should I be using only the oil? Seems to me you would not want to mix the grease and oil, but then I'm not a lubricant expert. As for the problem with the sloppiness, the bronze nut was missing the set screw that adjusts the nut for the amount of play. I use a good grade of way oil as it has a tacky agent to help it leave a film of oil on the threads.

Traditionally, the parting tool needs to be moved into the workpiece using the lathe's cross-slide ; it moves in the X-axis. Although a milling machine is the optimal choice for the requisite drilling and milling, we experienced no problems performing the work on a drill press fitted with a cross-slide vice, which is recommended.

What is a Cross Slide?

Lathe Machine Parts
There are several ways the part could be located with the programmable gantry, but the simplest and most reliable is with a simple touch probe mounted on the machine's cross-slide table. Workhandling can make or break it; fast, flexible systems answer needs of near-net-shape turning. Dictionary browser? Full browser?Learn something new every day More Info A cross slide is a machine tool part that allows movement of a tool post or workpiece along two perpendicular planes during machining.
Cross slides fall into two categories: those that support tool bits such as lathe cross slides and workpiece supports used on milling machines and drill presses. A lathe cross slide serves as a mobile platform for a static tool bit when performing facing operations. The milling machine or drill press cross slide moves a workpiece across the axis of a revolving tool bit to effect cutting operations. Both types typically achieve their motion by means of two lead screw mechanisms which allow for a high degree of control and very precise advancement.
Precision machine tools such as lathes and milling machines rely on accurate introduction and advancement of their respective tool bits onto the face of the workpiece. The main difference between the two types of machine is the relationship between workpiece and tool bit. Lathes spin the workpiece in a precision chuck while the tool bit remains static in a tool post.
Machining is achieved by moving the tool bit against the workpiece to cut material away. Milling machines feature a revolving tool bit which is held static while the workpiece is advanced against it to remove material. Lathe cross slides are mounted on the saddle of the machine which straddles the bed of the lathe and traverses the length on the same axis as the rotating workpiece. The cross slide in turn offers a mounting platform for the tool post in which the tool bit is held.
When the saddle moves along the length of the bed, the slide and tool post move with it to make parallel cuts. When facing is necessary, the cross slide may be adjusted across the width of the lathe bed to cut the face of the workpiece. The cross slide may also be adjusted to move along the length of the saddle as well for additional fine adjustment. Milling machine and drill press cross slides afford the same level of fine advancement control as lathe slides. The major difference between the two however, is that the milling machine slide holds and advances the workpiece, and the tool bit rotates to make the cut.
This feature means that a milling machine cross slide will incorporate a specially designed vice that supports and immobilizes the workpiece. By turning the lead screw cranks, the workpiece is advanced to make contact with the tool bit to achieve the cut.Home What's new Latest activity Authors. Forums New posts Featured threads.

Most of my turning experience is on metal lathes. Manual and CNC. I've done some wood turning before and now have started some pens. It seems to me like a cross slide would be extremely useful for wood pens. I don't see any options to add one to a wood lathe though. I am looking hard at the Comet II lathe, but if there is an easy way to do it on another brand I am willing to consider. Dirtbmw20 Member. I think that lathe might have some problems with Damascus.

The other is a Atlas 12 inch commercial lathe compound that was for sale on this forum thanks Rick at a very reasonable price. The second problem is Atlas made a very short lower slide that offers very little support if for some reason you go past the slide as you most likely will and the tool catches the compound has had so much material removed and there is no support the compound snaps at the T slot.
Plus the compound is so narrow and the dovetails are a little shallow the compound often rocks during cutting. Some guys have removed the compound made a spacer and use there QCTH without it so there is no give.
Let's see if we cant fix that. This is good cast iron and cuts like butter. The casting will still be thicker in key areas because I will keep the tollerance tighter. Last edited: Apr 18, Dranreb Active User Registered.
Joined Sep 20, Messages I'll be watching this, as I do have a slotted cross slide that's much more rigid but a stiffer compound would be more useful to me. Well here we go milling out the main part getting ready for the dove tail. The dovetails are also cut to a ful depth the same as they are on the lower slide for greater contact area. The stock Atlas has a groove cut down the middle that does absolutly nothing but gathers chips and weakends the compound.
