PTI NAS of Belarus performs reconstructive and general maintenance of vacuum, press-forging, induction, casting equipment, heat-treatment furnaces, metal-cutting machines, electron-beam welding equipment

We offer the following types of work

• complete disassembly of all units and mechanisms
• check of the units and parts with lists of defects and cost estimates
• replacement or restoration of deteriorated units and worn parts
• precise adjustment, alignment and balancing of units and mechanisms
• general maintenance of basic elements with the recovery of their primary parameters that have been lost in the operation process
• bringing mating members and units in accordance with technical conditions
• adjusting and setting of automatic mechanisms and control devices
• transmission maintenance
• renewal of the outer appearance equipment with the recovery of lost titles and marks
• delivery/acceptance of the equipment according to all specified technical conditions

The services for modernization of the outdated equipment by replacing electron and electric parts to new and modern ones are possible. They allow to obtain the machine with advanced capabilities at a low investment

As a result of modernization, depending on its type, the customer gets the machine in the following state

• a machine is equipped with NC system with modern technological options
• outdated worn transmissions are replaced into new ones with improved characteristics
• outdated measuring systems (linear- and rotary displacement transducer) are replaced into the new ones with high accuracy and reliability
•  electric equipment of the machine is fully replaced into the advanced, small-scale, cost effective, quick-operating equipment with high reliability level
• automation program is set up; it allows to use all additional advantages
• the equipment is checked,  debugged, tested and put in commission, including the treatment of the initial batch and customer’s personnel training
• technological capabilities are limited only by the machine design
• there is an unlimited memory capacity for monitoring programs
• the data connection of the machines with PC and their  networking are possible
• advanced modes and types of the treatment are available

Specialists of PTI NAS of Belarus perform the whole range of repair, maintenance and modernization of induction equipment

Works include

• equipment diagnostics with drawing up a defect detection report
• calculation of the cost of repair or modernization
• performance of work on the territory of the PTI or on the territory of the Customer
• testing and starting up the equipment after work

In the course of modernization of the equipment at the request of the Customer work can be performed to replace the power supply by installing it with modern economical semiconductor converters on a thyristor or transistor basis. During modernization can be carried out replacement of

• CNC control systems based on modern industrial controllers
• control systems
• operator panels
• inductors
• cooling stations
