MARKING OF MASAM CUTTING TOOLS Marking for the material of the cutting tools for which material it is inteded is in accordance with the ISO standard at MASAM. Basic information before special cutting tool designin is machined material. When quoting the cutting tool, the customer will indicate the type of the material he wants to machine. The design of the tool begins with the choice of a suitable grade of solid carbide based on the material properties of individual carbides and machined material for each use. In addition, the most suitable coating and geometry of the cutting tools are designed...

Wide offer of standardized drills, as well as specialized drills according to the customer’s needs. With the standard types of drilling tools we offer various models of the tooltip. The number of steps and the relevant lengths and diameters of the step drill tool may vary up to the value Dmax, Lmax. The main advantage of the stepped drill, which is created on the basis of the customer specification are depicted in the pictures below. STANDARD APPLICATION 2. SPECIAL MONOLIT SOLID CARBIDE CUTTING TOOLS SPECIFIC APPLICATION With the standard application it is necessary to use several types of cutting...

MILLING Milling tools offered by our company enjoy great flexibility in shapes and types of shank solid carbide cutter. At each point, it is possible to illustrate the profiles of the milling tool. In case your requested tool profile is not listed in this catalogue, we are ready to process a tool design specially for you. D, D1, D2 ... .Dn: The individual diameters of the milling tools are designed according to the customer’s requirements based on the drawing documentation. The beginning of dimensioning from the tooltip with value D. Maximum tool diameter Dmax = 40 mm. 2.7 STEP REAMERS 2.9 CONICAL...

Above listed illustrations present some of the implemented projects. We create the form milling cutter specially for the customer according to his needs. It is possible to manufacture an angular cutter for a production of a lower cut or as a combined tool (creating a lower and upper cut on the workpiece) 12 2.

Tools can be designed as solid carbide, possibly with an additional insert depending on the tool application and its possible regrinding. 2.21 SHAPE TURNING TOOLS 2.19 DISC MILLING CUTTERS Shape turning tools, internal – on the left , externa – on the right MASAM’s product range includes also shape turning tools for specific customer requirements....

3 SPECIAL CUTTING TOOLS WITH CARBIDE INSERTS BROACHING TOOLS Broaching is productive machining method designed to produce precise circular and shape holes and slots, internal teeth or precise surfaces. This technology is mainly applied in serial and mass production when precision machining is required, especially for odd shapes. The broach tool contains three distinct sections: one for roughing, another for semi-finishing, and the final one for finishing. Accuracy of IT 6 and a surface roughness value Ra = 0.4 pm can be achieved. WHY BROACHING TOOLS MASAM • Reverse engineering used for design...

OUR OFFER OF THE PVD COATINGS: 1. TiN + AlTiN + Si – the coating consists of three layers, each component having specific properties. The use of the TiN layer prevents adhesion wear, which is used together with the AlTiN layer due to its high toughness and hardness. The last component of the coating is an extremely hard nanocomposite Si layer. The characteristic color of the coating is gold. Application of TiN + AlTiN + Si – This coating application can be seen with high alloyed steels with hardness above 60 HRC. Use of this combination is also suitable for machining of hardto-machine materials....

Our company also tests the suitability of individual coatings for a particular use. For maximum use of cutting tools and to ensure maximum longevity, it is necessary to determine the optimal solution also in terms of the coating used. Shown below, you can see testing of two coatings: TiN + AlTiN + CrAlSiN and TiSiN for a particular application in dry machining of carbon steel. Three contour machining strategies were compared. They were tested up to the determined wear criterion with roughness parameter Ra = 1.6 pm. Figure below also shows an example of a measured wear parameter that closely correlates...

We provide reports to our customers as a result of testing the durability of cutting tools after various specific modifications. On the picture below its shown an example of a report from regular qualitative analyzes of carbide materials. An example of the customer report from drilling can be illustrated by figure below, supplemented by images of a worn drill on the flank. As is generally known, tool wear occurs in three bands. In cooperation with our customers, we determine the end of the tool’s durability over the selected criterion. In this particular case, it was necessary to determine the...
