The impact of the thermal surroundings of CNC lathe centering machines

CNC lathe centering machine thermal surrounding environment, let Zhongcong intelligent equipment to give you a talk about it

CNC centering machine tool surrounding environment refers to the thermal environment formed by various layouts within the proximity of the machine tool. They include the following 3 aspects.

(1) Workshop microclimate: such as the distribution of temperature in the workshop (vertical, horizontal). When the alternation of day and night or climate and ventilation changes in the workshop temperature will produce slow changes.

(2) Workshop heat sources: such as solar radiation, heating equipment and high-power lighting radiation, etc., they are close to the CNC machine tool can be directly affected by a long time the whole or part of the machine tool temperature rise. Neighboring equipment in the operation of the heat generated by the radiation or air = flow way to affect the temperature rise of the machine tool.

(3) heat: the foundation has a better role in heat dissipation, especially precision CNC centering machine tool foundation should not be close to the underground heating pipeline, once the rupture leakage, it may become a difficult to find the cause of the heat source; open workshop will be a good "radiator", conducive to the workshop temperature equalization.

(4) constant temperature: workshop to take constant temperature facilities for precision centering machine tools to maintain accuracy and add I precision is very effective, but energy consumption is large.

Thermal influences inside the machine

(1) The structural heat source of the center-feeding CNC machine tool. Motor heat such as spindle motor, feed servo motor, cooling and lubrication pump motor, electronic control box can produce heat. These situations are permissible for the motor itself, but for the spindle, ball screws and other components have a significant adverse impact, measures should be taken to isolate. When the input power drive motor operation, in addition to a small portion (about 20% or so) into the motor heat, most of the movement will be converted into kinetic energy by the movement mechanism, such as spindle rotation, table movement, etc.; but inevitably, there is still a considerable portion of the movement process is converted into friction heat, such as bearings, guide rails, ballscrews and transmission boxes and other institutions heat.

(2) the process of cutting heat. Part of the kinetic energy of the cutting tool or workpiece in the cutting process consumed in the cutting power, a considerable portion of the deformation of the cutting energy and chip and tool friction between the heat, the formation of the tool, spindle and workpiece heat, and by a large number of chip heat conduction to the machine tool table fixtures and other components. They will directly affect the relative position between the tool and the workpiece.

(3) Cooling. Cooling is a countermeasure against the rise in temperature of the centering machine, such as motor cooling, spindle component cooling, and cooling of basic structural components. High-end machine tools are often equipped with refrigeration for the electronic control box, to be forced cooling.
