1 Had machining of steel gades up to 65 HRC High-efficiency cabide cuttes with ulta-high pefomance in had machining applications

2 Title END MILLS FOR STEEL UP TO 65 HRC SOLID CARBIDE END MILLS Highly efficient machining of hadened steel gades - outstanding duability, high pecision POKOLM's new solid cabide milling cuttes fo use with mateials up to 65 HRC have set completely new standads in this cutting application. The entie poduct line of ball and angula adius cuttes is distinguished by exteme duability, high pecision, and outstanding quality of finish. In tems of design, the heavy-duty tools stand out by a cutting edge geomety specifically optimised to tackle had milling applications, ounded out by a coating of unequalled wea esistance. The specially designed, tangential shaft tansition confes supeio bending factue stength compaed with conventional models. Diametes fom.2 mm to 12. mm and woking depths of up to 2 x d ae finely gaduated to meet a boad vaiety of custome equiements.

15 Use epot FROM PRACTICE TO PRACTICE JOB DESCRIPTION: Running two factoies in the city of Siegen, the Fuchs Schaubenwek company is enowned fo its sophisticated poducts such as fomed pats, specialpupose bolts, high-tension bolts, and steel constuction bolts. The oots of the owne-opeated, long-going fim with about 2 employees go way back into the ealy 19th centuy. Just a few yeas ago, the company's own tool poduction was upgaded with an Okuma-made machining cente, type "Genos M46R". This is used to fabicate lines of punching and foming tools made of tempeed HSS steel fo the poduction segment. Having said that, the machining of mateial is fa fom a tivial task, confonting the cutting tool with a couple of vey ticky challenges. Theefoe, Fuchs discussed the concete poblem of excessive cate wea and poo duability of the cabide cuttes with POKOLM's technical field epesentative in chage. The aim was to find a full cabide cutte capable of fulfilling the stingent equiements imposed by the cutting of tempeed HSS steel, which could be capable of cutting a specific test specimen in a face-to-face compaison. A convenient test object was found in a debuing matix taken fom the poduction pocess of special-pupose bolts. The Ø 6 mm cylindical pat had a height of 35 mm. 3 units wee to be made. The assignment was to machine a bevel with contous poduced in the middle of the top suface. MACHINE MATERIAL PROGRAMMING SYSTEM Okuma Genos M46R , 58+2HRC OSP-P3M-R In a pactical test, two cabide ball cuttes with 2 flutes and 4 mm diamete wee put to a diect compaative test in an identical setting. The two systems consisted in a highquality cutte as used peviously by Fuchs, and a POKOLM cutte selected fom the new line of poducts fo up to 65 HRC, which was as optimised in tems of geomety, cabide metal, and coating. The test specimen befoe and afte the machining pocess EXAMPLE FROM PRACTICE: Seat: Hydaulic chuck SK4 Cooling: Ai, exteio V c [m/min] V f [mm/min] n(s) [min -1 ] D c f a p a e , Tool: Competito poduct POKOLM, up to 65 HRC Tool life: 9 min 21 min Component pats: 3 units 7 units RESULT: The esult couldn't be much moe obvious: The new POKOLM system could handle 7 pieces acoss a tool life of 21 min. Showing massive cate wea, the conventional model had eached the end of the line afte 9 minutes and 3 pieces. But the POKOLM cutte did not only ate best with a view to tool life but also to efficiency. Competito milling cutte POKOLM milling cutte 15
