The document discusses the optimization of honing wheel structures to enhance machining accuracy and reduce wear in various grinding processes, particularly in motorcycle engine valves. It presents a motorized grinding attachment designed to improve efficiency and save labor in valve lapping by automating the process. The attachment is compact, cost-effective, and capable of achieving high precision finishes while being compatible with different lathe setups.

1. Abstract

2. literature survey
Honing wheel structure is optimized to improve
machining accuracy and reduce the honing wheel
wear in plane honing by .Guo
(2002).
The important characteristics in honing cast iron
cylinder blocks and the influence in the internal
combustion engine performance was described
and discussed by Anderberg, (2013).
The design optimization of segmented grinding
wheel structure on high speed was reported by
Zhang
(2010)./ /

3. literature survey
 Kanthababu (2008) used Acoustic Emission
(AE) signals from the machining process and
found that it is one of the most promising
methods suitable for tool condition
monitoring. In his work, AE signals are
monitored during rough and finish honing of
cylinder liner using fresh and completely worn
out honing tools.

4. Problem Identification
• Until now days many workshop are still using
manually with is using man power to do
lapping or grinding valve, this process are
usually take long time to done some time it
takes several hour. I decide to make a
motorize grinding valve for motorcycle engine
to make it easier and save man power for
lapping or grinding valve so man power can be
use for doing other work while waiting lapping
process done

6. • This attachment is used on centre lathes.
• This whole arrangement is fixed on the carriage where the
component rests. /
• A grinding wheel is mounted on the spindle which is supported by
two bearings, and is rotated by a motor through ‘V’ rope in high
revolution. “
.”
• While we are introducing the rotating grind wheel inside the bore
of a job which is also rotating on the chuck, Material will be
removed according to the cut which we select.
• In turning, a single point tool removes the material, but in this
process, a grinding wheel is used to super finish the jobs, where
high accuracy is necessary.

7. WORKING

8. • The attachment is compact and rigid in size.
• Low cost
• Low operation
• High efficiency
• Maintenance is less.
• It can be used on any lathe by small change in centre heights.

9. • Grinding inside the bore in any size of body can
be done.
• As the feed is given automatic, 0.8 micron finish
may be achieved.
• By changing the grades of grinding wheels it
can be used to grind the carbon steel, Alloy
steel and stainless steel etc.
