FAQ Jun 2020

For section "Engineering Materials"
QUESTION
What should be taken into account when machining Beryllium and its alloys?
ANSWER
In machining Beryllium (Be) and its alloys, the fine Beryllium dust generated while cutting the material can be dangerous to health. It is essential to use machine tools equipped with appropriate chip collecting units.
Due to Beryllium’s high brittleness, the machined surface may be damaged during machining by microcracks and microflow. To avoid surface damage, the machining process should be under control - rigid workpiece clamping and eliminating vibrations are extremely important.
Beryllium bronze, which is also known as beryllium copper or BeCu, has good machinability. When machining this alloy, users should follow ISCAR's recommendations regarding the cutting data that relates to copper alloys.
QUESTION
What is Zamak and how to machine it?
ANSWER
Zamak, also referred to as ZAMAK, ZAMAC, or Zamac, is a group of zinc-based alloys. The principal alloying elements are aluminum, magnesium and copper. These alloys feature good machinability and their cutting usually does not cause difficulties. ISCAR's tools for the ISO N group of applications are recommended for machining Zamak.
For section "MULTI-MASTER"
QUESTION
Does ISCAR provide a key with adjustable tightening torque for MULTI-MASTER heads?
ANSWER
Yes. The MULTI-MASTER product range includes an assembled key, comprising an adjustable torque handle with a set of interchangeable wrenches and TORX-tipped bits, designed for secure and accurate tightening of MULTI-MASTER heads. This key is an optional product and should be ordered separately.

Jargon
"Black" and "white" cutting ceramics
Meaning
– a commonly used classification of ceramic cutting materials according to their color. Pure alumina-based cutting ceramics are "white," while mixed ceramics comprising a composition of alumina with titanium carbide are "black".


For section "Milling Slots and Grooves"
QUESTION
What is the difference between indexable slotting cutters and slitting cutters?
ANSWER
Originally, slotting cutters were intended for milling slots and grooves while slitting cutters were used for slitting or cutting-off. Each type of cutters featured different accuracy requirements, and slitting cutters were less precise. However, technological progress has significantly leveled out differences between slotting and slitting cutters in indexable milling.
