Wells-Index builds a quality line of knee-type milling machines. With over 80 years of experience behind us, we can assure you that every mill we build is the best and is a U.S.A. manufactured product. A Wells-Index milling machine demands your consideration.

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute.

VoluMill toolpaths use smooth, flowing motion, eliminating sharp directional changes and variances in tool load. The constant material removal rates enable machine tools and cutting tools to operate under ideal milling conditions throughout, regardless of a part's shape or complexity. Customers are reporting as much as eight-times tool life.

Figure 8.3 Simplified calculation of the torque required to turn a mill. RI FULWLFDO VSHHG 3RZHU Figure 8.4 The effect of mill speed on the power drawn by a rotating mill. The liner profile and the stickiness of the pulp in the mill can have a significant effect on the actual critical velocity. Mills usually operate in the range 65 - 82% of

Index plate hole calculator. This is an online calculator to calculate what indexing plate to use and number of holes to skip for a given number of divisions. This calculator can be used for both rotary tables and indexing heads. The ratio below describes how many turns of the handle makes the table rotate one full revolution. For example, if

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K b LD 2.5 where k is a proportionality constant.

Wells-Index mills have a completely different milling head design than any other milling machine in the world. Most heads are based on a Bridgeport design and have been cloned by Taiwanese and Chinese manufacturers. The Wells-Index milling head is a much more robust and durable design for heavy cutting with most components such as the spindle

Computation of Example: The first step is to determine the mill rate: $312,000,000 / 1000 = $312,000 (example #1) $50,000 / $312,000 = 0.160 mills (example #2) The second step is to determine the residential property assessed value: $100,000 home x .115 = $11,500 (assessed value)

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters

The square face that cuts the positive a axis, has the parameters 1 a, b, c. Inverting these becomes 1/1, 1/, 1/ to give the Miller Index (100). The face on the back of the crystal that cuts the negative a axis has the parameters -1a, b, c. So its Miller Index is (00). Note how the negative intercept is indicated by putting a
