Transcript of CLT ver1.00

Mission

80% OPE (Overall Plant Efficiency).

90% OEE (Overall Equipment effectiveness).

100% in delivering the goods to costumers.

Work in accident free environment.

Develop Multi-skilled and flexible workers.

Higher confidence level among the employees

Work place cleans, neat and attractive.

Favourable change in the attitude of the operators.

Achieve goals by working as team.

Share knowledge and experience.

Strategic Goal

By implementing CLT (A maintenance tool) in the manufacturing industries.

To reduce manufacturing cost

To Improve the OEE (Overall Equipment Efficiency

To minimize the manufacturing losses (Downtime loss, Speed loss and Quality loss)

What is CLT ?

CLT is a basic medical science for machine in manufacturing. It is a simple tool to keep the manufacturing plant in a healthy state which can deliver at maximum efficiency.C: Cleaning – Eliminating dirt, dust, exposing all abnormalities, correcting minor flaws and establishing basic equipment condition.L: Lubricating – Reduce the Friction, Heat Generation, Overloading.T: Tightening - It only takes one loose bolt to start a chain of reaction of wear and vibration, as a machine vibrates slightly, other bolts work loose, vibration feeds on vibration, the equipment starts to rattle and shake, tiny cracks widen into gaping splits, parts become damaged and the result is major breakdown.

Introduction of CLT

Manufacturing Maintenance Operations Design Engineering

Plant and Site Management Project Engineering Engineering Inventory and Stores

In order to properly understand the impact of CLT, it is necessary to establish a definition. CLT (Cleaning/Lubricating/Tightening) is maintenance activities that are productive and implemented by all employees. CLT involves everyone in the organization from operators to senior management in equipment improvement. It encompasses all departments including:

Cost-Benefit Strategic Goals

Productivity 100-200% increases 50-100% increase in rates of operation.500% decrease in breakdowns Quality 100% decrease in defects.50% decrease in client claims Costs 50% decrease in labour costs. 30% decrease in maintenance costs 30% decrease in energy costs

Inventory 50% reduction on inventory levels.100% increase in inventory turns Safety Elimination of environmental and safety violations Morale 200% increase in suggestions Increased participation of employees in small group meetings

CLT Philosophy

Old Attitude“I operate, you fix.”“I fix, you design.”“I design, you operate.”

CLT Attitude“We are all responsiblefor our equipment.”

Management…Operators….Maintenance…Engineers…EVERYONE!

High Manufacturing Cost Phenomena

Machine

Machine breakdown

No Cleaning

•Rusting Occurs•Foundation Fixers loose•Misalignment•Vibration

•Generation of heat•Deformation of material property•High Friction•Extra load on Machine

•Misalignment•Vibration

No Lubrication

Availability lost•Machine Time Lost•Design parameters Lost•Speed Efficiency Lost

Process Efficiency Lost•Low production•Low Operators Confidence•Low OEE

Quality Lost •Loss of Raw Material•Loss of Manpower due to Rework•Low production•No customer Satisfaction on product quality & delivery

High Manufacturing Cost

No Tightening

Big Idea

Reducing the manufacturing cost by increasing the equipment efficiency

Getting operators involved in maintaining their own equipment and emphasizing proactive and preventive maintenance will lay a foundation for improved production (no breakdowns, stops and defects)

Operators need to develop ownership of their equipment, and become full partners with Maintenance so that they can perform as a tight-knit team to create maximum equipment effectiveness.

There are two components to this attack on waste — Asset care and CLT maintenance. These components denote the close collaboration between those who operate the machine and those who maintain the machine, both of which drive up availability while driving down costs.

How to Sustain CLT

Implementation of CLT

The implementation of CLT is necessary to increase the sense of ownership of equipment among the operators and developing their interest in work. The goal of increasing production can be achieved by active participation of operators. 10 step for implementation of CLT.

1. Announcement of CLT and top management commitment2. Outline a detailed master deployment plan 3. Classification and Responsibly of daily maintenance.4. Launch a formal training program for selected team5. Develop a CLT maintenance program for operators.6. Pilot Team building7. Identification of Tools & Cleaning Material required at different

station.8. Establish basic CLT policies and quantifiable goals9. Develop a preventive maintenance plan10. Follow ups and Continuous improvement
