Both grinding spindles are “synchronous direct‐drive spindles” with 19 hp peak eachClick image to enlargeRollomatic’s ShapeSmart NP30 replaces the original NP3+ model of pinch/peel grinder.

Pinch grinding offers highest concentricity, particularly on long and thin parts. The rough and finish grinding are performed in one pass, reducing cycle time. The machine uses two different grinding wheels running on separate spindles and positioned on independently‐ controlled CNC linear slides.

Both the finish and the roughing station have a separate direct‐drive synchronous spindle motor which provides better stock removal, less induced heat, better surface finish and longer wheel life.

Its redesigned workhead offers higher stability while grinding large parts, and can be switched from 10  ̊ to 90  ̊ in a few minutes.

It acheives excellent mirror surface finishes and near‐zero TIR for drill margins with repeatable results with tight tolerances and for long‐batch production.

Both grinding stations are equipped with super‐abrasive wheels with different grit sizes. One wheel carries out the rough grinding, while the other wheel is for finish grinding. The grit sizes and bond compositions are carefully selected to optimize the surface finish and find the right balance between minimal wheel wear and best cycle time.

Both grinding spindles are “synchronous direct‐drive spindles” with 19 hp peak each. The most important feature of a synchronous motor is that it provides constant speed and the torque curve is highly efficient. The rotational force is not reduced with higher RPM’s. Synchronous motors always run at a speed equal to their synchronous speed, as opposed to asynchronous motors (induction motors) which always have a lag.

The ins and outs of thread milling

There are many elements to consider when threading a workpiece. When is a solid carbide thread mill better than an indexable? How does the workpiece material behavior impact thread milling? Understanding your program as well as diagnosing issues that arise are just as important. Luckily, thread milling can be better understood by asking five specific questions.
