All machine operations are composed of a program, tools, and tooling. All three must be looked at before determining the fault. If a bored hole is chattering because of an overextended tool, do not expect the machine to correct the fault. Do not suspect machine accuracy if the vise bends the part. Do not claim hole mis-positioning if a center-drill is not used.  \nFind the Problem First  \nMany mechanics tear into things before they understand the problem, hoping that it will appear as they go. We know this as more than half of all warranty returned parts are in good working order. If the spindle doesn’t turn, remember that the spindle is connected to the gear box, which is connected to the spindle motor, which is driven by the spindle drive, which is connected to the I/O Board, which is driven by the MOCON, which is driven by the processor. The moral here is don’t replace the spindle drive if the belt is broken. Find the problem first; don’t just replace the easiest part to get to.  \nDon’t Tinker with the Machine  \nThere are hundreds of parameters, wires, switches, etc. , that you can change in this machine. Don’t start randomly changing parts and parameters. Remember, there is a good chance that if you change something, you will incorrectly install it or break something else in the process. Consider for a moment changing the processor’s board. First, you have to download all parameters, remove a dozen connectors, replace the board, reconnect and reload, and if you make one mistake or bend one tiny pin, it won’t work. You always need to consider the risk of accidentally damaging the machine anytime you work on it. It is cheap insurance to double-check a suspect part before physically changing it. The less work you do on the machine the better.  \nThis manual presents information for Horizontal machines, Lathes, and Vertical machines: Horiz is used to indicate Horizontal machines.  \nLathe is used to indicate Lathes.  \nVert is used to indicate Vertical machines.  \nVIBRATION  \nVibration is a subjective evaluation, which makes it difficult to determine, in mild cases, if there is an actual problem. In obvious cases, it is a matter of determining the source. Vibrations need to be distinguished from noise such as a bad bearing. Assuming that vibrations would be something that could be felt by putting your ha","cbCaicgziUoO1iC0","https://ap.wps.com/l/cbCaicgziUoO1iC0","pdf",58045195,417,"English","# GENERAL MACHINE T ROUBLESHOOTING\n## Before You Begin\n## Find the Problem First\n## Don’t Tinker with the Machine\n## VIBRATION","[{\"question\":\"What is the purpose and limitation of the Haas service manual information?\",\"answer\":\"The manual information is provided for reference and illustrative purposes for Haas machine owners.
