This is why it’s important to consider thermal growth for older machines

MTDCNC brings you an educational segment on thermal growth and why it’s important to consider if you’ve got old machines without a spindle chiller. Joining Rowan Easter-Robinson, Steve Rigby from HSM Components talks about thermal growth on his old HURCO machine and how he achieves such great tolerances for precise engine blocks. Large castings can expand when heated because of the amount of time spindles run for, and this can affect tolerances. Watch the video to know how Steve ensures effective roughing and surface finishes on his HURCO machine.
