Preventive Maintenance Machine Tool Service Inc.
What is Preventive Maintenance? A schedule of planned maintenance actions aimed at preventing unscheduled equipment down time. It is traditionally based on elapsed calendar time or fixed unit count usage. o Predominantly time and/or usage based o Typical periodicities: Daily, weekly, monthly, quarterly, semiannually, annually, and bi-annually o Customizable conditions-based maintenance o Tracked using a computerized maintenance management system (CMMS)
Maximize Availability Why Preventive Maintenance? o Maximize equipment availability o Minimize downtime o Use technicians efficiently Minimize Cost o Improved equipment reliability o Breakdown prevention o Reduce unscheduled interrupted or postponed assignments
Why Change Coolant? As coolant is used in a machine it becomes contaminated by oils, dirt, metal chips and other foreign debris. This contamination can have adverse effects on the machine, such as: o Rusty parts, shortened sump life, excessive foaming, discoloration, excessive bacterial growth, problems holding part tolerances or dimensions, and shortened tool life Often Metal chips and fines from cutting and grinding processes consolidate in the coolant sump causing microbial growth on the bottoms of coolant tanks By changing your coolant on a periodic basis, you will remove contaminants from your machines thereby decreasing the breakdown of the machine, tools, and tanks that result from ineffective coolant Bacteria and rust build ups due to poor coolant management
What is Predictive Maintenance? A maintenance technique that uses data from equipment and other relevant tools. These data allow events and trends in performance and equipment settings to be monitored through advanced analysis techniques and failure behavior profile matching. Analysis of component performance data and other indicators enable the identification, give warning, and prioritize impending or imminent unscheduled failures in advance. Predictive maintenance is complementary to condition-based preventive maintenance.

What MTS does for You MTS will develop a tailored preventive/predictive maintenance plan for each machine based on the manufacturer s recommendations and the customer s needs MTS manages maintenance schedules with a computerized maintenance management system (CMMS) - MaitenancePro MTS will schedule maintenance with the customer to minimize machine down time and maximize customer efficiency MTS will make recommendations on observations made during the maintenance MTS will maintain historical records of all maintenance conducted and will provide those records to the customer MTS will eliminate stress by tracking schedules, conducting machine maintenance, and keeping all historical records
Customer Expectations Fluid acquisition and disposal is the responsibility of the customer (MTS will alert 30 days prior to conducting PM) Replacement oil filters and batteries are the responsibility of the customer (MTS will alert 30 days prior to conducting PM) Findings of PM inspections could indicate required corrections charged at MTS hourly rate (options provided for customer s decisions no additional charges will be applied without the customer s explicit consent)
