This 630mm cylinder head straightedge ruler is a professional precision measuring tool, specially designed for detecting the flatness and warpage of engine cylinder heads, engine blocks, and other mechanical planes. With a standard length of 630mm, high-precision machining, and durable material, it can quickly and accurately measure plane deviations, helping mechanics and maintenance personnel complete engine overhaul and repair work efficiently. It is an essential tool for auto repair shops, engine maintenance workshops, and professional mechanics, complying with international certification standards and suitable for global sales.\u003c\/div\u003e\n\u003ch2 style=\"text-align:left\" class=\"heading-2 ace-line old-record-id-Hxx1fLqu9dYrHBcRlXtcHnmxnMf\" align=\"left\"\u003eProduct Overview\u003c\/h2\u003e\n\u003cdiv style=\"text-align:left\" class=\"ace-line ace-line old-record-id-WyyWfaCGpdULv3ch4V9cdBGLnNh\" align=\"left\"\u003eThe 630mm cylinder plane gauge straightedge is a core tool for engine maintenance, mainly used to detect the flatness of cylinder heads and engine blocks after disassembly or wear. Its 630mm length is perfectly compatible with most engine models, covering the main measuring range of cylinder heads and blocks. The tool adopts high-precision steel material and professional machining technology, ensuring stable measurement accuracy and long service life. It can effectively detect tiny plane warpage, avoid engine oil leakage, cylinder pressure loss and other problems caused by uneven planes, and improve the quality and efficiency of maintenance work.\u003c\/div\u003e\n\u003ch2 style=\"text-align:left\" class=\"heading-2 ace-line old-record-id-U7csfExSadWICDc138ScTVwinTh\" align=\"left\"\u003eCore Features\u003c\/h2\u003e\n\u003cul class=\"list-bullet1\"\u003e\n\u003cli style=\"text-align:left\" class=\"ace-line ace-line old-record-id-UqeEfDtJpdlDG8cU1r2ctIcpnEg\" align=\"left\"\u003e\u003cdiv\u003e\n\u003cstrong\u003eStandard 630mm Length\u003c\/strong\u003e: Fixed length of 630mm, perfectly matching the measuring needs of most engine cylinder heads and engine blocks, covering the key plane area, no need to splice measurement, more accurate and efficient.\u003c\/div\u003e\u003c\/li\u003e\n\u003cli style=\"text-align:left\" class=\"ace-line ace-line old-record-id-EMIQfNAWMdzCuBcRfGycRQeknSh\" align=\"left\"\u003e\u003cdiv\u003e\n\u003cstrong\u003eHigh Precision Machining\u003c\/strong\u003e: The ruler surface is processed by high-precision CNC machine tools, with extremely high flatness and straightness, ensuring measurement accuracy.
