We will use a inch diameter insert ball mill for semi finishing and finishing. Rigidity First, we must consider how one might process a truck mirror cavity mold. The rigidity of the machining center is a key element to the milling process. For this particular example we will presume that we have a
Feb 20, 2012I have a job to do that requires machining a 2" diameter hemisphere into solid cast iron. these are molds to cast zinc balls. There are 36 parts and each part has 6 of these hemispheres in it. I realize that this is not the best machine for the job but the only cnc machine I have to do this job is a Hurco KMB1 mill.
2013 6 6 Indexable Ball Nose End Mill for Finishing The S shaped end pro le allows for an edge sharpness similar to solid ball nose end mills. Radius tolerance of 6m for high accuracy finish machining comparable to solid ball nose end mills. Holders are available in 3 styles, steel, carbide and screw in, to suit different applications.
Jun 01, 2013The strong insert utilizes a chipbreaker shape that enhances cutting performance in face milling, side milling, slotting, contouring and profiling operations, while ensuring cutter rigidity. Figure 4High precision indexable finish ball nose end mills for superior surface finish and tool life.
The most critical tolerance in such high speed shafts is the concentricity which is usually required within 0.013mm TIR. Ball Mill Fanshaft Journals Tolerances on Fanshaft and Ball Mill journals will be held to the following subject to datum references. Roundness Taper and Concentricity +/ 0.00075" (0.02mm).

2012 2 20 Machining a ball mold As in your concerns 2" ball mill in a full radios plunge will create a lot of tool pressure. Also would the time you had in making the cutter and grinding it really offset the time to cut it with a 3D tool path. Also I never mentioned it before but the tolerance on the hemisphere diameter is +.003 and zero and the
2009 11 1 I ordered an 1/8' 4 flute center cutting end mill and received one that is marked 1/8', For metric reamers it can be a whole different ball game. We had some 12mm carbide reamers made approx. 10" long. Reamers are not made to the tolerance given for a particular size but are made to produce holes of that particular size from the first
