Insinööritoimisto Ismo Lindberg Oy manages also retrofit projects.
The retrofit project include the following basic operations:
Mechanical parts retrofit:
Machine complete dismounting, inspection of all parts and repairs of bad ones (body's and column's guideways grinding, bad screw-balls replacing);
New project for cinematic chains on each axis; Replacing of all bearings from speed bow and from main spindle with new one's type FAG and INA; Replacing of all sealing elements with new BUSAK+SHAMBAN types; Repairment/replacing of telescopic covers; Painting of machine on colour requested by consumer.
Hydraulic and lubrication units retrofit:
Replacing of all existing hydraulic and lubrication units, this being redesigned using ATOS, MARZZOCHI and MP FILTRI hydraulic and DROPSA lubrication devices;
New design for electrical installation:
Complete replacing of electrical devices with new ones type GE Power controls, TELEMECANIQUE and EUROGI being placed in a new electric cabinet; Performing the hard and soft projects for the machine's new electric installation;
Installing the new FANUC i-series CNC new FANUC digital drives and motors; NOTE: Other CNC, motors and amplifiers on customer requirement.
Installing new high-fiability measuring systems (HEIDENHAIN, ISKRA TELA);
Testing and putting in fuction:
Putting in function; Functioning, accuracy and geometrical precision tests; Test part machining according ISO 230 and NAS 979 standards; Instructions of customer's employees in order to operate the machine with the new CNC equipment; Suplying technical documentation in order to operate to machine after the retroffit process. NOTE: The above mentioned operations are not limitative. We can do other operations imposed by the technical condition of machine- tool and for ensuring all precision and fiability conditions guaranteed to the and-user.
