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.

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.

LATHE MACHINE PRICE IN INDIA

LATHE MACHINE PRICE IN INDIA

Lathe Machine Manufactured across the globe comes with different price tags, some are at higher price and some are at lower price. So, does Lathe Machine at Higher Price is better than Lower Price Lathe Machine?

Answer to the question lies to the CUSTOMER'S KNOWLEDGE. There are many customers who have wonderful knowledge about the products which they look to buy and at the same time, there are TRADERS/DEALERS mostly care about the price tags Machines offered at genuine price leads to Better Buy and does retain the customer.
