milling radius without rotary table supplier
1. Build a fixture that will locate the aluminum on the rotary table so I can repeatedly use the same setup without indicating for each of the 4 corners on each piece and each of the pieces in the lot. The fixture will also hold the work piece about 1/4" above the table surface to keep it from being damaged during machining.
3. Bolt that fixture to the rotary table such that each piece to be cut will be located with the center-line of the corner radius right on top of the rotational center of the table.
7. Advance the table further left some to avoid taking too big of cut and drop the quill down so the end mill will cut the entire thickness of the 1/4" aluminum on each pass.
Imagine the table is free to move in the X direction (i.e. by removing the the handle drive plate). [like disconnecting the cross slide of a lathe for taper turning]
It is then possible to arrange a radius arm A (say 12" long) with a fixed pivot at one end attached to the mills body and a pivot at the other end fixed to the table.
Attach a third arm C to drive the table from arm B at a point 1/10 along its length (see diagram - not to scale) and now as the carriage moves in the Y direction the table will prescribe an arc that ten times the radius of arm A (i.e 10")
You say you have a rotary table. Use it. Make a setup similar to the photos in RichR"s post. Do conventional milling, which we would find in that last photo where the end mill rotates to the right, and the table would be rotated in a counter clockwise direction, so that the cutter and work are moving in opposite directions. For a plate 3/8 thick I suggest going with a four flute end mill. It will give a fine finish and have less chip load per tooth than a two flute.
I have used it in the vertical position to cut a 107 tooth gear which isn"t covered by any of the dividing head wheels I"ve got. I set up an excel spreadsheet with the angle required for each tooth which isn"t as easy as it sounds as the rotary table is calibrated in degrees/minutes/seconds rather than decimal degrees so it took a bit of figuring out how to do it.

The new CNC-PLUS series (CNC260P and CNC302P) offer unique features in terms of performance, reliability and precision for any application or requirement. Already the previous generations of this series have always been used on a wide range of vertical machining centres, thus enabling a fourth axis with minimal effort. With a completely redesigned and updated clamping system and a new design that takes better advantage of the standard pneumatic supply, numerous applications and requirements can be met and machined without the need for an additional hydraulic power unit.
The latest generation of the braking system can provide a clamping torque of up to 1550 Nm maximised by pneumatics – that is 2.4 times stronger than the previous models CNC260 or CNC302 (1430 Nm are achieved with an air supply of 5 bar, with a typical workshop supply of 6 bar even 1550 Nm are possible)! Both 4-axis rotary tables can be mounted vertically or horizontally to adapt to any application and significantly improve both the capacity and performance of your machining centre!
This is an accurate designed table for milling, boring and other machine tools. This table allows indexing, facing and other work to be carried out rapidly with extreme precision. Tiliting range 0-90 degrees fromread more...
After the operator enters milling instructions into a computer, the 3-axis CNC machine will automatically complete the task by using a tool to cut along three axes — X, Y, and Z, or left-to-right, front-to-back, and up-and-down. Both CNC milling and CNC turning fall under the umbrella of 3-axis machining. However, they function slightly differently.
When using a 3-axis CNC milling machine, the material block remains fixed in a vice or on a machine bed. Rotating drills or cutting tools are connected to a spindle and move along the X, Y, and Z axes, removing shavings to accurately form the final component. 3-axis CNC milling machines are excellent for producing most geometries and simple parts.
By contrast, in the CNC turning process, the workpiece is attached to a rotating spindle, and a lathe shapes the component. As the spindle holding the workpiece rotates, a center drill or cutting tool traces the component’s outer and inner perimeters or creates holes along the center axis. Compared to CNC milling machines, CNC lathe turning machines produce parts faster and offer cheaper per-unit costs, which is advantageous for high-volume production runs.
Like 3-axis CNC milling, the cutting tool only moves along three axes and doesn’t maintain continuous contact with the workpiece in indexed 5-axis CNC machining. However, the machining table and tool head can automatically swivel in two directions between operations. Indexed 5-axis machining is great for manufacturing housings, jigs, and fixtures. It falls somewhere between 3-axis CNC milling and continuous 5-axis CNC machining in terms of speed, precision, and the ability to handle complex geometries.
Turning mill CNC centers are practically identical to CNC turning machines, with one exception — they’re equipped with CNC milling equipment. The workpiece is attached to a spindle that can either rotate or remain stationary while cutting tools remove material from it. By combining the elements of CNC lathe machines with milling tools, mill-turning CNC centers offer high levels of accuracy and geometric versatility, making them great for creating parts with loose rotational symmetries, such as camshafts or centrifugal compressors.
Not only do these types of 5-axis CNC milling machines offer greater accuracy when machining deeper parts and hardened materials, but they also offer higher yields and faster machining speeds. However, 5-axis machining is more expensive due to the specialized equipment necessary and the need for expert workers.
The main difference between 3-axis and 5-axis milling machines is that the workpiece can be worked on from three axes with the former and five axes with the latter. Both are highly versatile, automated, and replicable production processes that will enable you to quickly and cost-effectively create accurate components. However, you may opt to use one over the other for a variety of reasons.
