& History Present time HISTORY The tool production in Hulin began in 1934. The firm was founded by Mr. Studeník who named the new company " First Moravian factory" for saws and tools". At first the company started producing hand saws, circular saw blades and was gradually enriching the production programme with cutters for wood cutting and other tools for wood working. In the 1960th the production assortment enriched with TCT circular saw blades, gang saw blades, planner knives, machine knives, metal cutting tools and saw bodies. In the years 1948-1992 the firm was a state-owned enterprise....

Bimetal - Material M42 special electron-beam weld DIN type 1.3247 hardness approx. 67-69 HRC HSS- flat wire M51 Blade back made of alloyed spring steel DIN type 1.3207 hardness 69 HRC with high tungsten and cobalt content Flexible: Body of band saw blade is manufactured from special alloyed spring steel. It is highly flexible with hardness of about 50 HRC. It is an ideal basis for long life-time and excellent cutting performance. Tough and Resistable Tooth tips made from HSS steel in M42 or M51 material version. The best bonding Both materials are undetachably welded together. All...

Tooth forms Only well-chosen tooth shape can effectively cut with low- vibration. Four basic types are available. Standard tooth Hook tooth 0° rake angle Positive rake angle N H Variable tooth with positive hook angle Variable tooth 0° rake angle Positive rake angle V-0 V - POS Specialisation: low vibration cutting structurals Specialisation: low vibration cutting solid material Specification: Positive rake angle 1,25 + 6 teeth/inch Specification: 0° rake angle variable tooth pitch of 3/4 to 10/14 Specification: Positive rake angle variable tooth pitch of 0,75/1,25 to 4/6 Product range:...

Corrcect tooth pitch » optimum performance For optimum cutting performance of Bi-Metal band saw blade it is essential to choose the right toothing for individual application. Choose either Standard tooth form with constant tooth pitch or Variable tooth form with unevenly spaced teeth. Combined toothing is recommended for cutting of problematic material with vibration reduction. Recommended toothing for cutting solid material Constant tooth pitch Cross section N= Standard tooth shape H= Hook tooth shape Variable tooth pitch Cross section V-POS= variable tooth shape with positive hook angle...

Instructions for right usage » band saw blades » Troubleshooting Breakage of band saw Blade guidance is too far from cutting piece or wrong set up. Blade guidance is worn-out. Radius arm is loose. Drive discs Drive discs of the band saw must be kept in good condition and properly balanced. Machine Band saw guidance and radius arm Control and set up the guidance of the band saw regularly. Control its guiding wear and if needed, replace it. Set up the guidance arm as close to the work piece as possible. Curved cut Worn-out drive disc. Discs are too small- try thinner band saws. Blade guidance...

1. It is necessary to pay the same attention to band saw blades as to other tools. Please check especially: - band saw back jamming - twisting and dulling of band saw 2. Keep the band saw in good technical condition. Please check especially: - if the fixing clamp and straightening mechanism are functional - if the hydraulic pressure, cooling fluid are sufficient and circular wheel are parall - if not so, it is absolutely needed to change or set up the mechanism. 3. Put the band saw on clean, chip- free circular wheels. Insert band saw between circular wheels, straighten band saw properly...
