To check the thread you may use a thread gauge or a workpiece with an internal thread
M30 x 1.0

If the thread is having the exact size, the thread cutting process may be terminated. Now
you may again shift the operating lever of the lead-screw nut in standstill. In this way, the
connection between the lead spindle and the bedslide is interrupted.

General working advice - coolant

Friction during the cutting process causes high temperatures at the cutting edge of the tool.
The tool should be cooled during the milling process. Cooling the tool with a suitable cooling
lubricant ensures better working results and a longer edge life of the cutting tool.
INFORMATION
Use a water-soluble and non-pollutant emulsion as a cooling agent. This can be acquired from
authorised distributors.
Make sure that the cooling agent is properly retrieved. Respect the environment when dispos-
ing of any lubricants and coolants. Follow the manufacturer's disposal instructions.
