Each alignment plane has offset and angular components, so there are actually four alignment parameters to be measured and corrected. They are horizontal angularity (HA), horizontal offset (HO), vertical angularity (VA), and vertical offset …
I decided to convert this horizontal milling machine into a vertical milling machine. I wanted more room between the table and the cutter so I made an exten...
Hence, milling which might take minutes to accomplish in a SPEX mill could take hours in an attritor or days in a horizontal ball mill. All of these processing routes, however, have very low energy conversion efficiency, in that only a small fraction of the milling energy expended effects microstructural change contributing to the MA process.
Use the Lateral Alignment level to make sure that the alignment tool is approximately horizontal width-wise. See Figures 27 and 28. Vertical Alignment Bubble Level (Original design only) Lateral Alignment Laser Level (Original design shown) Location for Digital Inclinometer (Preferred Method) Magnetic Attachments (3)
Establish vertical and horizontal centerline of mill and pinion shaft against the effects of this, we recommend that the trunnion bearing sole plate be crowned so as to be higher at the center line of the mill. This is done by using a higher shim at the center than at the ends and tightening the foundation bolts of both ends. Ball Mill Sole Plate
Radial or Rotational turret alignment inspection checks. Most CNC lathe turrets have a tool post slot that is milled into them at every station for grooving or turning tools. This slot should be parallel to the axis (usually X) in the cutting position. If there is not any slots, you will need to use a coaxial indicator to sweep the bore.
The step by step procedure of rim and face alignment method is explained below : Measuring and documenting as-found misalignment conditions . Documenting is done on above diagram.To obtain a complete set of as-found readings, perform the steps below: Rotate the dial indicators to 12:00. Set the face dial indicator to zero.

X movement being square to Y movement isn't as critical on a horizontal mill as it is on a vertical, because you can only cut in one direction on a horizontal. 'It may not always be the best policy to do what is best technically, but those responsible for policy can never form a right judgement without knowledge of what is right technically' - 'Dutch' Kindelberger
Use of angle plates – head horizontal – vertical mode. Extending the area for vertical milling – 2. But if the angle plate is the other way round, the distance in the y direction is much smaller but the space from the cutter downwards is greater. 448 vert milling horiz mode 2. Fig. Extending the milling area 2 448.
alignment target, be it zero or some desired value to compensate for thermal growth. In most cases a quick glance at the table will tell whether coupling misalignment is allowable or not. As an example, a machine with a short flexible coupling running at 1800 .
I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling …

Pictured is a great example from our article on a successful manufacturer that is so productive with their Horizontal Mills they only need 2 1/2 machinists–it's a family business. They load and unload the tombstone (which is the big upright chunk of cast iron the parts are held to while machining) while the machine is busy cutting new parts on a tombstone in the machine.
Feb, 2019. Evolved by addopting a TH3 coating on 4-flute ball end mill for high hardened steel processing. On high-hardened steel processing, to achieve even longer tool life. Highly efficient cutting with 4 flutes. Special edge shape in tip area improves cutting performance. TH3 Coating provides long tool life even on hardened steels.

mills and ball mills for use in the mining and cement industries. By current stan-dards, girth gears can be as large as 14 meters (46 feet) in diameter, 1.1 meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on the mill structure to pro-
