When selecting oil to coat a granite base, the core principles are “protection firs, no damage, easy cleaning.” Selection must consider the base’s purpose (precision measurement/ordinary tooling) and transportation environment (humid/dry), focusing on avoiding corrosion, residuees affecting subsequent use. Specific selection methods and recommendations are as follows: I. Core Oil Selection Standards (Must Read) II….

The core of oiling is “thin, uniform, no omissions, no residue.” It is essential to form an effective protective film while avoiding thick application that causes sticking, residual contamination, or affecting subsequent installation and use. The specific steps and details are as follows, applicable to all recommended oils (specialized protective oil, industrial white oil, emergency…

High-Precision CMM WorktableWhy Premium Precision Granite (Jinan Qing) is the First ChoiceExtremely long-term dimensionay, virtually permanent deformation resistanceNatural granite has undergone natural aging over hundreds of millions of years, completely releasing internal stresses. Unlike cast iron or steel, it does not cr, deform, or age over time, perfectly matching the high-precision reference requirements of CMMs.Extremely…
