1. Relationship between machine speed and cutter diameter

– parameters

After work position of gear lever (used for selection of gearbox speed) should be

changed. For example if machine worked with 200 rpm speed, it should be switched to

400rpm.

The above rate on ordinary quality steel <500N/mm2, such as S185, S235JR,

S275JO and use a sharp tool.

For steel <700N/mm2 like E295, S355N,C45, speed should be reduced by about

35%.

2. Guidelines for grading diameters of twist drills when drilling
holes.

Drilling holes of a diameters greater than 18mm should be carried out by preliminary

drilling where a diameter of a first hole should be 0,7 of a final hole diameter.

For example: When drilling a 23mm diameter hole it is recommended to initially drill it using a

drill bit of 16mm in diameter and to increase a size of a tool gradually to reach a diameter of

the desired hole.
