1. loaded movable parts;
2. motors;
3. pumps;
4. reservoirs of oil and coolants.
In addition the machine as a whole or its separate parts take up heat from the environment of the shop, solar heat, heat from heaters, etc heat varies at different times of day and year. To reduce the influence of temperature deformations of Mrs should:
1. before performing the precision work you must bring Mrs a stationary temperature regime. This can be done either through the operation of the machine at idle (within 2 – 3 hours) or by execution at the beginning of the change inaccurate work;
2. it is rational on the machine sources of heat or use of insulation (for example, by using thermal screens);
3. to use refrigeration devices to MDM, stabilizing temperature;
4. rationally designing individual parts of the machine;
5. in particularly important cases to process in temperature-controlled workshops.
