The invention relates to a bearing platform used for a sputtering type coating machine, which comprises a first bearing tool and a hollow second bearing tool.
本发明涉及一种用于溅镀式镀膜机台的承载台，其包括：一第一载具及一中空的第二载具。
The second bearing tool is closely connected with the bottom of the first bearing tool and used for absorbing the heat transmitted by the bottom of the first bearing tool.
该第二载具与该第一载具的底部紧密结合，用于吸收该第一载具的底部传递的热量。
Continued to use of tool wear, spindle axial force will be increase, leading to bearing damage, but will also affect the accuracy and effectiveness of engraving.
