Nettet30. jan. 2007 · hmm, funny, i just clearanced my mains last night. no line honing. no line boring. NO GODDAMN ACL BEARINGS!!! the motor had just under 10k miles on it. with all new OEM bearings to the specs on the block/crank, everything came out perfectly clearanced, right in the middle of honda's tolerances. In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder. Boring is used to achieve greater accuracy of the diameter of a hole, and can … Se mer The boring process can be executed on various machine tools, including (1) general-purpose or universal machines, such as lathes (/turning centers) or milling machines (/machining centers), and (2) machines designed to … Se mer For most lathe boring applications, tolerances greater than ±0.010 in (±0.25 mm) are easily held. Tolerances from there down to ±0.005 in (±0.13 mm) are usually held without especial difficulty or expense, even in deep holes. Tolerances between ±0.004 in … Se mer • Kalpakjian, Schmid (2001), Manufacturing Engineering and Technology, Upper Saddle River, NJ, USA: Prentice Hall • Todd, Robert H.; Allen, Dell K.
