The SFM is used to calculate the RPM of the spindle and workpiece. RPM is based on the material being cut, the material of the cutting tool and the diameter of the material being cut.

To garantes high precision for all tools during the machining process in the following examples we advise mounting them on Hydro Preziss hydro centric chucks.

When using the parting off tool, set the RPM to about 1/4 of the calculated value. When drilling, calculate the RPM based on the drill bit diameter, rather than the workpiece size.

PREZISS, as a specialist in polycrystalline cutting tools (PCD), is aware of all the features required for the manufacture of complex special cutting tools. PCD profile tools are essential components  for high performance and finish on double profiling machines, moulding machines, spindle moulders, covering all needs of profiling and moulding. Those are a technically advanced tool group that can be used effectively on materials used in the furniture industry as well as other industrial sectors where very hard and abrasive materials are used.

Common materials have a calculated value, called surface feet per minute or SFM, for the maximum speed that a tool can move through the material, without excessive wear or damage.

Extremly stable steel body construction that conferees the cutting tool a reliable performance in hard working conditions. Designed to achieve large profile depths combining teeth along the profile required according to customer specifications, the Preziss cutters have a 0,02 mm concentric accuracy for a super finishing. mounting the cutting tools in a Hydro sleeve gives the tool a good dumping protection for a long tool life.

When it is time to start cutting, turn the spindle speed to a low number and start the spindle. Slowly turn up the speed until the readout is close to the calculated RPM.

Setting the lathe to use the correct speed (spindle RPM) for the operation is important. Determining the correct RPM takes a combination of research, observation and common sense.

Note: Observation and common sense will also help determine the correct speed. For example, if the tool is chattering and making lots of noise, something is wrong. Stop, look at the cutting tool, recalculate the speeds, and ask Shop Staff for help if needed. If the formula calculates an extremely high RPM, perhaps your math isn't correct. If you have questions about the RPM, see Shop Staff for help.
