 Welcome to this machine tool video, tilting the head on a manual mill. Commonly, vertical milling machines are used to machine surfaces that are parallel or perpendicular to the spindle. However, there are times in which angular features may need to be machined on your part. To accomplish this, the head of a vertical milling machine can be tilted from side to side or forward to back. In this video, we will be demonstrating how to tilt the head of a vertical milling machine side to side. Using the same wrench as loosening and tightening the drawbar, loosen the four bolts on the front of the spindle head. Do not remove them. Once the bolts are loose, rotate the bolt on the right side of the spindle head to tilt the head of the milling machine. Rotating the bolt counterclockwise will result in the head tilting clockwise. Conversely, rotating the bolt clockwise will result in the head tilting counterclockwise. If the head needs to be tilted beyond 30 degrees, the pin located on the left side of the spindle head will need to be pulled. Rotate the head to the desired angle using the angular scale located on the right side of the spindle head. This is a semi-precise measurement. To set the head of the milling machine more precise, a bevel protractor will be used. Set the bevel protractor to the desired angle and using the quill, line the quill up to the protractor. Once the spindle head is at the desired angle, snug the bolts on the front of the spindle head. Double check nothing moved and you are still at the desired angle. Tighten up the bolts. If tilting the head forward or back is required, loosen the three bolts on the right side of the ram. Do not remove them. Once the bolts are loose, rotate the bolt located at the top of the ram to tilt the head forward or back. In addition to cutting surfaces of your part parallel or perpendicular to the spindle head, the spindle head of the vertical milling machines can tilt to cut surfaces at desired angles. This concludes our machine tool video on tilting the head of a vertical milling machine.
