It is fully operational from Head Stock Front Levers. Machine Video is available at http://www.youtube.com/watch?v=8l6465yRlQ4  
• Head Stock Gears: There is high difference in the making of the head stock as there are number of gears are linked to each other in All Geared Lathe which is not in the Semi geared lathe. All the gears are induction hardened in the Head Stock whereas it may or may not be hardened gears in the Head Stock of Semi Geared Lathe.

These are the few differences in both the machine and at the same time there is a difference in the Lathe Machine Price as well. Due to the major difference in the making of the machine, there lies difference in the price
 as well. A buyer need to have a look at the above mentioned difference before they buy the machine for their industry. So depending upon the requirement, a buyer can chose the machine to buy.

Lathe Centers

Centers

Centers are useful in holding the work in a lathe between centers. The shank of a
center has Morse taper on it and the face is conical in shape. There are two types of centers
namely
(i) Live center
(ii) Dead center

Holding Work Piece Between the Centers

The live center is fitted on the headstock spindle and rotates with the work. The
center fitted on the tail stock spindle is called dead center. It is useful in supporting the other
end of the work. Centers are made of high carbon steel and hardened and then tempered.
So the tip of the centers are wear resistant. Different types of centers are available according
to the shape of the work and the operation to be performed. They are Ordinary center, Tipped center, Revolving center. Lathe Machine Manufacturer Preet Lathe Udyog offers Dead Center/Ordinary Center as standard accessories along with the Lathe Machine and other centers as optional.

Leadscrew

LEADSCREW APPLICATION

The LeadScrew is a long threaded shaft used as master screw. It is brought into operation during thread cutting to move the carriage to a calculated distance.

The LeadScrew is held by two bearings on the face of the bed. A gear is attached to the lead screw and it is called as gear on LeadScrew. A half nut lever is provided in the apron to engage half nuts with the LeadScrew.

LeadScrew & Half Nut

LeadScrew is used to move the carriage towards and away from the headstock during thread cutting. The direction of carriage movement depends upon the direction of rotation of the LeadScrew.When the LeadScrew is kept stationary, the half nuts are engaged with the LeadScrew to keep the carriage locked at the required position. Lathe Machine Manufacturers manufactures Lathe Machines  with LeadScrew which helps the operator during Thread Cutting, which is the main and the only work which can be obtained for LeadScrew. Preet Lathe Manufactures machines either 4 TPI or 2 TPI and if required they customize as well.

LATHE MACHINE MANUFACTURER

MANDREL USAGE FOR 

LATHE MACHINE MANUFACTURER

A previously drilled or bored workpiece is held on a mandrel to be driven in a lathe
and machined. There are centre holes provided on both faces of the mandrel. The live centre
and the dead centre fit into the centre holes. A carrier is attached at the left side of the
mandrel. The mandrel gets the drive either through a catch plate or a driving plate. The
workpiece rotates along with the mandrel. 

There are several types of mandrels and they are:

1. Plain mandrel 

2. Collar mandrel
3. Step mandrel 

4. Cone mandrel
5. Gang mandrel 

6. Expansion mandrel

A good Lathe Machine Manufacturer uses it to check the accuracy from Chuck to the Center, which is done by the usage of the Dial Gauge, it is in Microns. Preet Lathe Udyog makes sure, it is properly checked to attain the best accuracy

Conventional Lathe

LATHE MACHINE BASIC

Bed is mounted on the legs of the lathe which are bolted to the floor. It forms the base
of the machine. It is made of cast iron and its top surface is machined accurately and
precisely. Headstock of the lathe is located at the extreme left of the bed and the tailstock at
the right extreme. Carriage is positioned in between the headstock and tailstock and slides
on the bed guideways.

Lathe Machine Parts

The top of the bed has flat or ‘V’ shaped guideways. The tailstock and the carriage
slides on these guideways. Inverted ‘V’ shaped guideways are useful in better guide and
accurate alignment of saddle and tailstock. The metal burrs resulting from turning operation
automatically fall through. Flat bed guideways can be found in older machine tools. It is
useful in heavy machines handling large workpieces. But then the accuracy is not high. It is the Lathe Machine Manufacturer who should possess this knowledge to help hos client for the right machine.

Apron Mechanism

Apron Mechanism

Apron is attached to the carriage and hangs over the front side of the lathe bed. It is
useful in providing power and hand feed to both carriage and cross-slide. It is also used to
provide power feed to the carriage during thread cutting through two half nuts.

APRON in LATHE MACHINE

Power is transmitted from the spindle to the lead-screw and feed rod through the
spindle gear and tumbler gear arrangement. A worm is mounted on the feed rod by a sliding
key. The worm meshes with a worm gear on whose axis another gear G1 is attached. Gear
G1 is attached to a small gear G2 by a bracket as shown in the diagram. Gear G4 is
positioned to be in mesh with the rack gear always. Another gear G3 is mounted on the same
axis of gear G4. The carriage hand-wheel meant for longitudinal feed is attached to the gear
G5 on the same axis. The gears G3 and G5 are always in mesh. The gear G6 is attached to
the cross slide screw.

The feed selection lever can be kept in neutral, up and down positions to obtain the
following movements.
1. Hand feed and power feed to the carriage
2. Hand feed and power feed to the cross slide

All Geared Lathe

ALL GEARED LATHE

 

All Geared Lathe are one of the most easily operable machines in Lathe Machine Industry. Usually it comes with Full Norton or Quick Change Gear Box. The reason it is easily operable because & majorly some job requires extra speed or RPM then these machines are there to deliver it. Also, if the job requires really Low RPM then again this machine offers the same.

Preet Lathe offers All Geared Lathe with 18 Different Spindle Speeds, which helps the machine operator to change the Speed of the Spindle according to the requirement of the Job which can be either less RPM or High RPM. Preet Lathe machine is offered lowest RPM - 10 & Highest RPM - 2000 & in-between there are total 18 different speeds which can be set accordingly with just a flick of the Lever Handles. With the addition Norton Gear box it becomes it easy to cut the Thread rather than changing gears from the rear side of the machine which utilizes time & effort. Lathe Machine is offered with Flame Hardened Bed with Turcite Fitting which is optional however this does increases the life of the machine thus retaining accuracy.

All Geared Lathe Vs Cone Pulley Lathe

All Geared Lathe Machine

Lathe which is equipped with All Geared Headstock  is easy to operate as there is no manual slip of Belt from one step to any other. All Geared Lathe have three or more than three shafts mounted within & it is shown in the picture below.

All Geared Lathe Headstock View

 The gears are equipped to obtain different speeds, which can be more than 18 spindle speeds. The middle shaft has got three gears D,E & F as a single unit, thus will rotate at similar speed. The spline shaft also have three gears mounted as A,B & C on it. The three gears can made to slide with the help of the lever mounted in front of the Headstock as shown below.


All Geared Lathe - Preet Lathe Series

This movement enables the Gear A to contact with the Gear D or with other gears. This sliding movement on the either of the shafts with the help of the levers, different gears get in touch with each other & these gears are connected to the main Spindle. So, with the rotation of the Electric Motor Pulley, these gears are also in drive and rotates the spindle, producing different RPM. All Speed Changes are done with the series of levers on the front of the Headstock & are like shifting gears in a Car.

Cone Pulley or V Belt Drive Lathe Machine

The V Belt Lathe Machine or famously known as Conventional Lathe Machine in Batala or Cone Pulley Lathe Machine is one of the oldest form of the Lathe Machines, in which the different speeds are obtained with the help of the belt arranged on the four different steps of the cone pulley. A step Cone Pulley is attached with the Head Stock Spindle.

Cone Pulley Presentation

 The Conventional Lathe Machine or Cone Pulley Lathe has four steps as in the above picture (A,B,C,D) & on the other side there is another pulley which also have four steps (E,F,G,H) which is placed parallel to the Spindle Cone Pulley. Both the Pulleys are connected with the Belt and the V Belt is connected to the Electric Motor. The Belt can be arranged between the steps A&H, B&G, C&F & D&F manually, thus the required speed is attained. The Spindle speed will be maximum when the belt is arranged between A & H while the minimum speed will be attained when the belt is arranged between D & E. In this kind of Lathe, Operator have to slip the Belt from one step to another manually.

All Geared Lathe Headstock

Headstock Composition

All Geared Lathe Machine are manufactured with the usage of the most advanced technology as it contains the minor to the major accuracy work, which is not possible without the EXPERTISE of the Expert Lathe Machine Manufacturer. 

HEADSTOCK EXPLODED VIEW

All Geared Lathe

A Headstock contain numbers of gears so that different speeds or RPM can be obtained. It is very important to use the right material for the Gears & the Shafts and not to forget Headstock Spindle. Carbonized Material is regarded as the best material for these gears & so as for the Shafts. The headstock is made of robust material as due to cutting forces involved, which can disturb the performance as these forces can reduce the quality of the finished workpiece.

The Spindle is hollow, so that long pieces or bars can be extended to the work area. The Main Spindle runs in Bearings and is fitted with some means of attaching work-holding devices such as Dog Chucks or Three Jaw Chucks. This end of the spindle usually also has an included Morse Taper, to allow the insertion of Dead Centers or Live Centers or Tapers. All Geared Head use a gear box driven by a dedicated electric motor & it allows the Machine Operator to run it on different speeds by changing the Lever Positions given series.
