Auto parts CNC machining to maintain strict tolerance requirements skills
Mar 07, 2018

One of the tricks to keeping tight tolerances in CNC machining for auto parts is that the spindle warm-up to keep severe tolerances.Running a warm-up routine, which is standard for most CNC machining parts for auto parts, is a typical procedure that will only warm the spindle if it is considered to run some more strenuous work, which is good for applying grease to prevent bearing premature Wear will also seem crucial.

 

However, if we need to get the internal components to a stable operating temperature, we should expect thermal expansion. That's all right if you just want to keep tight tolerances on the Z axis, but that will have to go further if we want to combine the spindle preheating with the machine's movement on all axes. Allow auto parts CNC machining machines to run for 10-20 minutes, all parts moving to allow parts to reach the desired temperature, then also helps to reduce the impact of thermal expansion during milling.

 

Whenever it comes to CNC machining of automotive parts, care should be taken at the end of the warm-up period to ensure that all tools are accurately measured and then strict tolerances maintained.

The second of the tricks to keeping tight tolerances in CNC machining for auto parts is to pay attention to tool choices that keep tight tolerances.

 

Carefully choose our tools, and when we deal with these intolerable tolerances, it must adapt to tools. We need to ensure that we have specific tools for roughing and finishing that allow roughing tools to withstand wear and keep last-minute processes for finished tools, and then repeat the process to create precise parts.

 

Auto parts CNC machining to maintain strict tolerance requirements of the third is to strict compensation.

 

The compensation for our tools,it is not perfect for tool builders, and the tools they design are somewhat forgiving. And at this point, the first thing to do when setting a precise job is to be aware of the actual tool diameter that should be used. Exact tools should be used to verify the dimensions.
