High-precision constant-temperature lathe

Abstract

The utility model relates to high accuracy constant temperature lathe, including the organism, the processing cabin in the organism is provided with lathe main part, be equipped with the liquid cooling servo motor for driving main shaft or screw rod and with the nut that screw rod constitutes screw rod cooperation on the lathe main part, be provided with refrigerating system on the organism, the refrigerating system at least includes the cold liquid pipeline of circulating flow, the liquid cooling servo motor and nut are respectively set up first heat exchange flow channel and second heat exchange flow channel, first heat exchange flow channel and second heat exchange flow channel are connected in series on the cold liquid pipeline, the liquid cooling servo motor and nut are respectively connected in series or parallel connection on the refrigerating system through first heat exchange flow channel or second heat exchange flow channel, this lathe connects liquid cooling servo motor and nut mechanical structure on the refrigerating system, reduces the temperature of mechanical structure through the refrigerating system, reduces the thermal expansion deformation of mechanical structure, can promote the precision of processing.
