ABOUT OUR ORGANIZATI ON

Microfine Bushings Private Ltd., was incorporated in the year

1981 with the vision of establishing itself as a pioneer in precision

machining. Ours is an ISO 9001:2008 certified organization. We are

now an established source for precision machining of components

and subassemblies to Defense, Aerospace, and Automobile Indus-

tries. Since inception, we have been striving continuously to

achieve maximum customer satisfaction by delivering quality prod-

ucts & services through proper systems and processes.

Our Quality Policy**

Our Management Principles

• Put Customer satisfaction First and educate the same

ently high on our customer commitments. New and Repeat

enquiries and orders have increased from 75% to 90% ap-

proximately which proves our cost competitiveness and cus-

tomer satisfaction. We have Successfully Indigenized 5 Sub-

assemblies for Aerospace, 5 Sub-assemblies to defense in-

dustries.

About our Organization

We have synergized the vision of our country with that of ours

in making India a self sustained place for defense & Aero-

space products. We are one of the pioneers in indigenization

of such products and some of them are listed below.

Developed in the year 1997, Rammer chain assembly was our

first indigenized development. It is a part of the automatic load-

ing gear (ALG) mechanism which is responsible for loading the

ammunition into the barrel of the T-72 & T-90 battle tank. We

are successfully delivering them to defense till date.

OUR VISION ON INDIGENIZED DEVELOPMENT

RAMMER CHAIN ASSEMBL Y

Dream it! Do it!

Developed in the year 1986 for Indian Defense .Provides a spill

free joint for both pneumatic and hydraulic applications ranging

up to 1000 bar.

QUICK CONNECT-DISCONNECT SELF SEAL COUPLINGS

Developed for Indian defense in the year 1997, controls pre-

cisely elevation and traverse of the gun.

CONTROL PANEL ASSEMBLY

Dream it! Do it!

Developed in the year 2008. It is used for pneumatic services

to the liquid stages of Launch vehicles which has to separate

safely during lift off of the launch vehicle (Rocket). It is a mis-

sion critical assembly.

UMBILICAL CONNECTOR ASSEMBLY

Developed in the year 2004. It is a pyro device responsible for

solar panel deployment of the satellite.

CABLE CUTTER ASSEMBLY

Dream it! Do it!

Developed in the year 2012. It is used as part of the sighting

equipment of the rocket launcher responsible for precisely fixing

the target in elevation as well as in traverse.

CLICKER ASSEMBLY

Developed in the year 2012. One of the critical sub assem-

blies responsible for transmitting the power from the cylinders

to the crank shaft. It used in hi-torque UTD engines of battle

tanks & other military vehicles.

CONNECTING ROD ASSEM BLY

Dream it! Do it!

Developed in the year 2013. It acts as a pivot joint in gimbal

actuation during the last stage (PS4) of PSLV. It is a mission

critical assembly.

UNIVERSAL JOINT ASS EMBLY

Developed in the year 2014. Advance angle coupling forms a

part of fuel injection systems responsible for delivering the re-

quired amount of fuel to the hi-torque V-46 & V92S2 engines.

ADV ANCE ANGLE COUPLI NG ASSEMBLY

Dream it! Do it!

Developed in the year 2015. Toothed Rack Assembly forms a

part of fuel injection systems responsible for delivering the re-

quired amount of fuel to the hi-torque V-46 & V92S2 engines.

TOOTHED RACK ASSEMBL Y

Developed in the year 2016. Booster Assembly comes as part

of fuel regulating system and it is responsible for increasing the

pressure of the fuel by 2 bars.

BOOSTER PUMP ASSEMBL Y

Dream it! Do it!

Major sub-assembly used for PSO XL stage in Launch vehicle.

It is responsible for PS0 ignition of solid stage I

IGNITER HEAD END ASS EMBLY

It is a part of the electro-hydraulic actuator of the L40 stage of

the launch vehicle. The inner diameter of 90mm to the length of

200mm is controlled within 20microns

RESERVOIR SHELL

Dream it! Do it!

Momentum Wheel Assembly which is used in the inertial system

units is a satellite flywheel energy storage system.

MOMENTUM WHEEL ASSEM BLY

DIAPHRAGM

Made of Titanium alloy in which the curve radius and the sur-

face finish are very crucial parameters.
