2. MATERIALS USED FOR PRODUCTION OF TOOLS

Symbol Name Description

HSS High-speed steel Standard material for general purpose cutting tools

Material with high heat resistance, cobalt content
HSSE High-speed steel allows to increase the hardening temperature and
(HSCo5)
improves the stability of cutting edges.

This homogeneously structured material for tools,
obtained with the use of powder metallurgy, has
High-speed powder
HSSE-PM the high-hardness and high-temperature resistance
steel
properties, which ensure that the tools made with
it are characterized by high stability of cutting edges.
The homogeneously structured material for tools,
obtained with the use of powder metallurgy from the
Micrograin cemented tungsten carbide, features high abrasion resistance
VHM
carbide and hardness. In comparison with the high-speed
steel it is more brittle and usually used with the
PVD coatings

3. PVD COATINGS USED FOR TOOLS

High performance properties of the HL coating have been achieved by application of the advanced
nanocomposite structure. TiAlN layer, with its high hardness and temperature resistance, provides a stable,
resistant to abrasion base of the coating. The top WC/C layer consists of tungsten carbide nanocrystallites
surrounded by a carbon ply features excellent tribological properties. Hard WC separations provide abrasion
resistance, while maintaining excellent the sliding properties of carbon. By combining advantages of two
layers, the HL coating is ideal for processing of a wide variety of materials, it improves chips evacuation,
reduces cutting forces and protects cutting edges from the impact of high temperatures. The HL-coated
tools can work with the minimum quantity of lubrication (MQL). The coating is designed for processing 11
materials from the Groups P, M, K, N, S.
