WhatsApp: +86 18838072829The most common way to fasten the arbor in the milling machine spindle is to use a draw bar. The bar threads into the taper shank of the arbor to draw the taper into the spindle and hold it in place. Arbors secured in this manner are removed by backing out the draw bar and tapping the end of the bar to loosen the taper.
WhatsApp: +86 18838072829Making a square broach to fit in the mill spindle might be a way to approach the square corners. A piece of 1/2" drill rod, for example, milled to a square shape on one end and then hardened could be used in the mill spindle as a broaching tool moving the spindle up and down by hand while feeding the X and Y axis in small increments.
WhatsApp: +86 18838072829Using a Chart to Find the Center of Holes on a Bolt Circle. Milling. A simple chart can save a lot of time in finding the center of holes on a bolt circle. Instead of setting up a rotary table or calculating the centers with trig, just multiply the diameter of the bolt circle by the constants on the chart for the XY offsets.
WhatsApp: +86 18838072829Sometimes the only solution is a larger, more rigid, more precise machine to do the job, and sometimes you can get it done by modifying the process and/or materials used.
