PORTABLE MINILATHE

PORTABLE MINILATHE

• It is that of all the machines employed by the mechanic to aid he in his work

• The lathe holds the honor of having been the first machine tool. From it all other machine tools have been developed as they are.

LITERATURE SURVEY

PORTABLE MINILATHE

• Length of the bed• Width of the lathe bed• Height of centers over the bed• Distance between centers• Swing diameter over the bed• Over the carriage• Max diameter of all through spindle• Power of the motor• Modes of drives• No. of spindle speed• Lead screw details• Weight and floor space required

Specification Of Conventional Lathe

PORTABLE MINILATHE

• Types of Lathes• Speed lathe • Engine lathe• Bench lathe• Tool room lathe• Semi automatic lathe• Automatic lathe

Types Of Lathes

PORTABLE MINILATHE

• Producing cylindrical jobs• Turning • Taper turning• Drilling • Boring • Knurling• Screw thread cutting• Reaming

Functions Of Conventional Lathe

PORTABLE MINILATHE

• Lathe is known as the mother machine tool• It is one of the most widely used machine

tools in all parts of the world. • An engine lathe is the most basic and simplest

form of the engine lathe• Engine lathe derives it’s name from the early

lathes, which obtained their power from engines

INTRODUCTION

PORTABLE MINILATHE

• Bulky • Placed at a fixed place• Maintenance• Huge space required• High initial cost

Conventional Lathes

PORTABLE MINILATHE

• Concept The portable mini lathe is a simplest wood

turning machine having simple constructional parts which favors less effort to operate.

PORTABLE MINI LATHE

PORTABLE MINILATHE

• Need The conventional lathe machines are suffering

from its bulkiness to carry it to preferred workspace. We need to admit the workshop for even light operations like internal design parts, modification etc. The PORTABLE MINI LATHE is specially designed for carpenters to carry light operation within his workspace. The operator can carry the machine itself anywhere as he porting his tools.

PORTABLE MINI LATHE

PORTABLE MINILATHE

• Portability• Lathe performance within the workspace• Lathe operations with the tool available the

carpenter• Feasibility multiple operations• Machining of light metals• Economic

OBJECTIVES

PORTABLE MINILATHE

PROJECT MODELThe main parts incorporate the PORTABLE MINI LATHE are,•Headstock (Hand drill)•Wooden bed•Head stock carrier•Hand drill support•Wooden tailstock

PORTABLE MINILATHE

The main parts incorporate the PORTABLE MINI LATHE are,

•Tailstock guide way•Stud•Clamp•Hinge•Screws •Bolts•Washer•Chisel

PORTABLE MINILATHE

• Portable mini lathe uses hand drill as headstock

• It can be driven by minimum power

• Three wooden clamp is used to fix the drill

• It is light and compact to assemble and disassemble

HEADSTOCK

PORTABLE MINILATHE

SPECIFICATIONS• Type – portable• Net weight of the drilling machine – 1.4 kg• Speed at no load – 22oorpm• Power – 450W

PORTABLE MINILATHE

• Jack enables to facilitate minimum pitch to adjust the height

• Can fix easily• Rigid support

SCISSOR JACK

PORTABLE MINILATHE

• It made up of combination of wooden block and steel ball bearing

• The dead centre made up of aluminum

TAILSTOCK

PORTABLE MINILATHE

Dimension

• Foundation 150x120x18mm

• Wooden block65x65x125mm

PORTABLE MINILATHE

LATHE-BED

• Mini lathe uses a wooden bed which interns reduce the weight as compared to metal

• Slot provided ensures to and fro motion of tailstock

PORTABLE MINILATHE

Dimension

• Lathe bed- 2(550x320x18)• Slot - R8x350

PORTABLE MINILATHE

GUIDE WAY• Guide way which guides

the tailstock to and fro movement accurately

• It is made up of stainless steel C-members, that is obtained by cut out one side of square member.

PORTABLE MINILATHE

Dimension

• Length-450mm• Width -20mm• Height-12mm

PORTABLE MINILATHE

• Metal/ wood cutting; metal and the wood as required dimension were cut with the cutter and the jig saw at the mechanical workshop.

WORKSHOP FACILITY USED

PORTABLE MINILATHE

WORKSHOP FACILITY USED• Drilling; holes are drilled on the metal as well as the

wood at the lathe workshop with the radial drilling machine and the hand drill

PORTABLE MINILATHE

WORKSHOP FACILITY USED

• Grinding; cut structural members were grind at the mechanical workshop.

PORTABLE MINILATHE

Welding; the structural members were welded together to build the stand and plates were welded to the scissor jack to get it fixed on the bed. The tailstock centre was welded the ball bearing then the clamp

WORKSHOP FACILITY USED

PORTABLE MINILATHE

WORKSHOP FACILITY USED• Fitting; the tailstock centre produced by grinding and

filing the aluminum rod of diameter 15mm.

PORTABLE MINILATHE

WORKSHOP FACILITY USED• Carpentry ; shaping the wood and cut the slot on the lathe bed is done at the carpentry

PORTABLE MINILATHE

ASSEMBLY

• Mobility• Perform every operations , considering with

conventional lathe• Simple and compact• Easy to handle• No need extra manpower• Very cheap• Less power consumption• Fixed anywhere

ADVANTAGES

• Difficult to perform large workpiece• Skilled labours required• Vibration problem

DISADVANTAGES

• Perform operations on wood and aluminium• Power available is limited

LIMITATIONS

• Perform operations such as,1. Turning 2. Grinding3. Cutting4. Polishing• Applicable in carpentry workshop.

APPLICATIONS

• Portability• Lathe performance within the workspace• Operations with tools available the carpenter• Economy• Feasibility of multiple operations 1.Turning 2.Grinding 3.cutting 4.polishing
