A Slotting machine is also eligible to introduce as shapper machine. The slotting machine is very much similar to a shaping machine in many ways, except that the ram which moves up and down in the vertical direction. Hence we can also call it vertical shaper. This machine is quite useful for making square shaped holes, keyways for fitting, cutting additional materials etc. Here cutting actions are performed in a vertical direction.
Basically, a slotting machine is used for performing
below tasks on huge and difficult to handle work items.
A lathe machine can be explained as the shaping tool that turns a part on a rotating shaft to accomplish various operations such as deformation Drilling, knurling, sandling, cutting etc.
With the help of this machine tool that are
made out of the workpiece to create objects with center axis.
Esskay Lathe machines and tools will tell you
about the lathe machine and the various operations which could be done with the
help of this machine.
Esskaymachines- parts of lathe machines

Operation of Lathe Machines
The lathe machines are excellent for application like shaping pottery. An excellent example is a Potter’s Wheel. Most acceptable provisioned for metal working lathes. These can also be taken into consideration for production of solids of rotation, screw threads, helices and plane surfaces. Fancy lathes are able to fabricate three dimensional solids with staggering complication. The workpiece is normally clasped by one or two holders. Where an individual is able to move that part horizontally to adjust working on the piece lengths. The few other holding techniques include clamping at the rotation of axis with help of collet or chuck, face plate, clamps etc.
1. Turning:-
Turning is the most usual sort of operation carried in almost every single lathe machine ever produced. Turning can be explained as the process of getting rid of the extra material form the workpiece to generate a cylindrical surface to the required length. The workpiece is placed right between the centre and spinned at the desired pace. The lathe machine then starts making a movement in the longitudinal direction in order to move towards the headstock along the perfect cut of depth. The surface finish is absolutely good.
2. Facing:-
It is a process of diminishing the total
length of the piece by putting it into the square which leads to the axis of
lathe. The process of decreasing a surface that is flat at the endpoint of the
workpiece. The chopping edge of the sharp toll could be considered as the
height same as of the workpiece centre.
3. The Chamfering Process:-
The Chamfering process can be defined or
explained as the obtaining of the bevelled surface at edge of a workpiece that
is cylindrical in geometry. The process is accomplished just when the shaft and
bolt ends. The Chamfering plays an excellent role to avert from the damages to
the very sharp edges and safeguard the process for the people operating the
lathe while engaged in other work. Chamfering on bolt plays a crucial role to
hold the screw (nut) fimly.
4. Knurling operation:-
The knurling operation is the process of
attaining a diamond structure on the workpiece in order for a little assistance
for grip it more perfectly. A proper or perfect grip is the main reason when
the surface is administered by hands only. This twisted task can only be done
with the knurling tool. This smart mechanism comprises of a station of
accustomed steel roller and is able to hold the toolpost much rigidly. The fact
is knurling is supposed to be done at an extremely low speed. It is
applicable/useful on the handles and ends of gauges. The feed varies completely
between 1 to 2 mm per coupe. At Least three to two cut is essential to furnish
with full potential.
5. Thread cutting:-
It is the significant process in which the lathe needs to acquire the steady spiral cut better known as threads. Whenever such threads or spiral cuts are created on the outer surface on the workpiece is known as outward thread cutting. The threads or spiral cuts are created in the inner surface on workpiece is known as internal thread cutting. This workpiece is revolving in and around 2 centres i.e. dead and live centres or the lathe. The smart mechanism is then advanced vertically to acquire the needed type of the thread. The tool when preceded from the right direction to the left direction one can get the left handed thread. Likewise whenever the progressed from left to right one can have the right handed thread. The movement of the carriage here is furnished with the lead screw. A couple of change in the gears moved the lead screw by moving around the handle which is the depth of cut can be administered.
6. Filling:-
This is said to be concluding procedure which
comes into the picture right after turning. It is carried on lathe to get rid
of burrs, sharp corners and the trail marks on workpiece while also in an
attempt to drag it to the size by eliminating even the smallest metal traces.
The entire process comprises of getting a flat single cut file through and over
the workpiece that revolves at a high pace. The pace is normally 2 times as
compared with turning.
7. Polishing:-
This work comes into action when the filing is
done in order to get the surface quality improvised workpiece. If the polishing
is done with the finest quality emery cloth right after filing is done successfully
delivers in extremely smooth and bright surface. The lathe runs at a rate of
1500 to 1800 rpms and oil is taken into consideration on the emery cloth.
8. Grooving:-
It is the task of eliminating the workpiece
diameter when it has a really tapering surface. And it could be done only with
the help of the grooving tool. A grooving tool is identical to the detachment
tool. It is quite normally done at the edge of a thread which falls adjacent to
the shoulder in order to leave a tiny border.
9. Spinning:-
It is the task of the creating a minute metal
sheet by turning the lathe machine at a higher pace and then pushing it against
a headstock axle. Reinforcement is needed from the tailstock edge.
10. Forming:-
It can be explained as the task of transforming
a convex, concave or of any asymmetrical structure.
11. Drilling:-
Drilling is the process of creating a hole
that is of a cylindrical shape in the wall. It can be done with the help of a
rotating rotating mechanism. The rotating part of the slicer better known as
the drilling drill. During this procedure the workpiece us moving in and around
a faceplate, or a chuck and the drill is held against the drill holder of the
tailstock and the chuck of the drill chuck. The material is pulled out and is
impacted by the motion on the tailstock axle. This technique is accepted widely
for the drilling shaped workpiece.
12. Reaming:-
Reaming is the process which could be
explained as the task of finalizing and classifying a hole which already has
been bored or drilled. The mechanism is known as reamer which comes fitted with
multiple plate cutting fringes. The reamer is held up against a tailstock axle,
directly or through the drill chuck and is uphold at a fixed destination while
the work is revolved at a very slow pace.
13. Boring:-
Double head boring lathe machine
Boring is the task of expanding of the hole which has been drilled already, forged, puched. However it cannot result into a hole. Boring is identical to the exterior turning task which can be carried out in a lathe. In this procedure the workpiece is rotated in a faceplate or chuck and the mechanism are fixed into the work. It comprises of a boring bar that just has one single point cutting mechanism which expands the hole. It also rectifies the cylindrical-ness of a hole. This technique is adopted for boring tiny sized jobs only. The only thing is that the pace of the process is slow.
14. Tapping:-
Tapping is explained as the procedure of
slicing the threads of small diameter threads that are at the interior while
taking into consideration a multi-cutting mechanisms better known as the tap. A
lather the object is upheld on a faceplate or on a chuck and whirled at a very
slow pace. A tap of the needed expanse is upheld against the axle.
Conclusion
Above mentioned are some of the terms needed to be acknowledged before understanding what is a lathe machine operations and how it works. So far Esskay lathe machines and tools the well named Lathe machine manufacturer have covered all the important operations that are accomplished with the lathe machine.
The lathe machine is a kind of machine where in work item is rotated on the axis to do the operations like cutting, turning, drilling, boring etc.
Lathe Machine Cutting
Tools
Maximum times, single point cutting tools are used for general work, and multi point cutting tool is used for special operation only. Lathe machine cutting tools are further categorized as per the method of using tool and feed mechanism

A) As per the method
of using tool
1. Turning Tool
Under the category of
turning tool, cutting tools are further classified as
Rough Turning Tool – The main function of the rough turning tool is to shed the maximum chunk of unwanted material of work piece with in the minimum time span.
2 Finish Turning Tool- the main function of the finishing tool is to add finishing touch to the work piece once the major chunk is removed by the rough turning tool. This tool works with precision.
2. Chamfering Tool
Chamfering tool is used to finish the edges of the work item to prevent the breakage from the uneven edges.
3. Shoulder Turning Tool
When your work item has different diameters and
cutting tools used to machine the all diameter by moving from one to another
diameter it is called shoulder and hence the tool is called should turning
tool.
4 . Thread Cutting Tool
Thread cutting is one of the most important operations of the lathe machine. Thread cutting tools are further classified as external and internal thread cutting tools. Principle of both thread cutting tools is the same and there is different of tool and location of the work item.
5. Facing Tool
Facing tool of lathe machine is used to flat
the surface of the work item and also used to limit the work in the required
length. In the facing operation, the tool is adjusted in a perpendicular
position to the axis of the work item. It is also a kind of finishing tool.
The length of the facing tool ranges from 125 mm, 140, 170, 200 to 240 mm.
6. Grooving Tool
Grooving is done on the work item to make it fit for the grinding operation without touching shoulders and it makes the nuts to move smoothly.
7. Forming Tool
Forming tools are further classified as simple forming tools and flat dovetail forming tool. The purpose of forming tool is to impart the predefined shape to the work item.
8. Boring Tool
The basic purpose of the boring tool is to bore the hole in work item in the required depth and diameter. The boring tool is affixed the boring bar and boring operation is performed.
9. Counter boring Tool
Counter boring tool in the lathe machinery performs the
operation of expanding the original hole bored. It is basically done to provide
space to bolts, studs etc. The counter boring operation can be performed by an ordinary
boring tool.
10. Under cutting Tool
Under cutting tool is
similar to the grooving tool. In this also clearance angle is provided on all
sides of the tool.
B). As per feed
Mechanism
1. Right-Hand Tool
A right-hand tool is used to feed on
tailstock to the headstock while performing operations like turning, cutting,
etc. A right-hand tool is located on its left-hand end.
2. Left-Hand Tool
A left-hand tool is used to feed on the head stock to the tail stock ie left side of lathe bed to the right side.
3. Round Nose Tool
This is turning toll and can be fed either from the left side of lathe bed or from the right side to the left side of the lathe bed.
