Repairing and Maintenance:-

  Maintenance, repair, and operations (MRO) or maintenance, repair, and overhaul involves fixing

  any sort of mechanical, plumbing or electrical device should it become out of order or broken (known as

  repair, unscheduled or casualty maintenance). It also includes performing routine actions which keep the

  device in working order (known as scheduled maintenance) or prevent trouble from arising (preventive maintenance). MRO may be defined as, "All

  actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function. The actions include the

  combination of all technical and corresponding administrative, managerial, and supervision actions."

  MRO operations can be categorised by whether the product remains the property of the customer, i.e. a service is being offered, or whether the

  product is bought by the reprocessing organisation and sold to any customer wishing to make the purchase (Guadette, 2002). In the former case it

  may be a backshop operation within a larger organization or smaller operation.

 Benefits of the Annual Maintenance Contract (AMC)

 In today‚Äôs competitive era, quality is a prime factor. Quality output from any machine depends on machine's repeat performance. To get repeat

 performance; machine maintenance is a key factor. Maintenance of machines with Computerized Numerical Controls requires special skills. Every

 organisation may not have specialized CNC maintenance team to take care of all variety of CNC machines. CNC machine manufacturers are the best

 people to support in maintaining these machines as total technology is available with them. In order to help our customers in getting the best

 throughput from the machine, we have introduced the concept of Annual Maintenance Contracts for the CNC controllers.
