Low thermal displacement bed
Brings ingenuity to the bed shape and rib layout, and minimizes strain caused by room temperature, etc.
Heat isolation cover
Using CAE analysis, we have achieved a GL4i coolant route that is not easily affected by heat. By adding an isolation cover, a layer of air is created between the bed and the coolant route, which reduces the amount of heat that is transferred to the bed.
Wheel spindle with improved heat-release properties
The GL4i wheelhead’s heat release property reduces the temperature elevation of the bearing oil. The installation of an air type wheel spindle bearing lubricant fan reduces the temperature elevation of the bearing oil.
