108 TPM-A Route to World-Class Performance

Table 5.5 Problem solving: vibration

Cause Remedy
1 Out of balance Correct or replace
2 Bent shafts Straighten or replace
3 Poor surface finish Rework surface
4 Loose nuts and bolts Tighten
5 Insecure clips Secure clips
6 Insufficient mountings Get extra added
7 Too rigid mountings Get softer ones
8 Slip stick Lubricate
9 Incorrect grade lubricant Clean and replace
10 Worn bearings Replace
11 Excessive speed above standard Reduce speed to standard
Some of the remedies will require a skilled maintenance fitter. Others can be carried
out by the operator with some training (items 4, 5, 8, 9 and 11).
Vibration is identified by sight, touch or noise increase.

of the importance of tackling adjustment is given by the percentage figures
based on hard experience shown in Table 5.7.
Set-up and adjustment are so important in the drive towards reduced
losses, better equipment effectiveness and ultimately world-class manufacture.
Shigeo Shingo, the guru of Single-Minute Exchange Die (SMED), states the
following in his book A Revolution in Manufacturing: the SMED System: 'Every
machine set-up can be reduced by 75%'.
What a challenge for Western companies! The SMED approach uses a
derivative of the Deming circle:
Focus Set-up video
Analyse Pareto, ergonomics
Develop Script, simulate, agree
Execute Train, measure, honour, empower
In the SMED system, success is subject to certain conditions:
e An attitude The team wants to score.
An empowerment The team has a budget.
An involvement Management is part of the team.
A commitment Management sets the target.
A philosophy Step-by-step improvement.
Moreover, the SMED approach suggests that there are characteristics common
to all set-ups:
Prepare, position, adjust, store away
Internal and external activities
From last good product to first good product
