2 TEHNIAL ATÁLOGO TÉNIO ATALOGUE SIERRAS METAL-UTTING IRULARES IRULAR PARA METALES SAW BLADES Three generatins We are specialists in the prductin f cutting tls fr the metallurgical and car industries. Since 192 and fr three generatins we have wrked with the same innvative spirit and an identical cmmitment t creating the finest cutting slutins at all times. At Jem we have an exceptinal understanding and admiratin fr the mechanics, heat transfer and chemistry f irn and ther metals. Tday Industrias Metalurgicas Jem S.A. is a majr internatinal cmpany and a market leader. We exprt t five cntinents and cntinue t wrk as hard as we did at the start, s that yu, ur custmers, will always find us yur mst reliable chice. creating cutting slutins

In rder t imprve and surpass the results f a cutting prcess with cnstant pitch adjustment, Jem has decided t incrprate an irregularity int the cntrlled, set pitch adjustment, cmbining this with machines where feeds are cnstant and revlutins are adjustable. The main advantages f this system are as fllws: > It reduces the vibratins, nise and heat caused by all cutting prcesses. > It enables the user t increase the feeds f the machine, saving time and mney with every cut. > It bsts perfrmance and prductivity. > It slves prblems caused by uneven cutting thickness. > Imprved perfrmance in cuts with rectangular tube angles.
