History of Hawema GmbH
1984 - 1993
Development of grinding units as so-called retrofitting sets for manual tool and cutter grinders by Hubert Haller. Using these special indexing units enabled retrofitting and modernizing of manual tool and cutter grinders and so backlash free re-sharpening of helically fluted tools.
It was a revolutionary matter in the tool and cutter grinding field at the time. About 1.200 of these units were sold worldwide in the before mentioned time period, also to many renowned companies. The ongoing developments resulted in the production of two and three axes machines.
From 1994 onwards started development and design of the first HAWEMAT five axes tool and cutter grinder (HAWEMAT 2000). This unique machine represented an extraordinary innovation for complete machining of cutting tools in the world market. Worldwide patents and patent applications as well as different awards underline all the advantages of such a new machine conception. The unique of this machine is the kinematic concept - the arrangement of the five axes: X- and Z- axes are designed as a so-called cross axes configuration. The B- axis (swivel range of 210°) is a rotary table double supported on the vibration resistant mineral compound machine base. The Y- axis for spindle infeed is assembled on the B- axis frame and the C- axis (work head stock) can rotate 360°. Cutting tools can be ground in narrowest area by using this axes configuration. Thanks to the possible very short axes travelling dead times can be reduced by the user increasing the productivity.
In March 2000 the HAWEMAT 3000 was introduced. This machine was based on the HAWEMAT 2000. A maximum amount of stiffness and rigidity was achieved by the double supporting of the grinding column (Y- and B- axis). So this machine is absolutely qualified for production of high precision tools. HAWEMA developed for these CNC machine tools automatic tool handling systems, integrated as a so-called Pick-Up Loader in the machine hood.
In the year 2002 the HAWEMAT 2001 five axes tool and cutter grinder was introduced into the market. This machine was based on the model HAWEMAT 2000 taking over the "double support" of the grinding column from the model 3000. The HAWEMAT 2001 is a five axes CNC machine for cost effective re-sharpening of cutting tools and production of high precision new ones. A fully accessible (from all sides) machine cabinet is based on a massive and rigid mineral compound machine bed offering the possibility of attaching automatic tool handling systems.
A further innovative step in this year was the creation of a strong collaboration with NUM as the supplier for the machine control and grinding software. NUM is offering worldwide dominating software for tool and cutter grinding and together with the new digital Axium Power control plus MBLE axes amplifiers the appropriate power drive technology for our machine tools. So we get the complete electric, electronic and software from one supplier for our machine tools.
Mid of 2005
The HAWEMAT 2000/5 ECO five axes CNC tool grinder was presented as the latest development in Hannover at the EMO 2005. This concept was created in order to offer an "uniqueness" for the re-sharpening market in price and power. The HAWEMAT 200/5 ECO is not a cheap "low cost product", rather an up to standard machine tool enabling also the production of small and smallest tools. All mechanical components, inclusive the "double support" of the grinding column, are according to the technical HAWEMAT 2001 standard.
