CUT OFF High Speed Steel slitting Saws from HSS/Dmo5 and HSS/Emo5
Company GSP- High Tech saws s.r.o. produces HSS circular saw blades in diameters varying up to 720 mm in various designs. The tooth forms most used are HZ, BW, B, AW, A, VP and 'Chipbreaker' . Production is based on DIN standards 1836, 1837, 1838 and 1840, extended by the refined company GSP manufacturing standards. The delivery program consists of a range of standard sawblades which can be delivered from stock and a range of special sawblades to be produced to customer specifications.
The HSS sawblades are supplied as standard in high speed steel grade M2 = DIN 1.3343, but can also be delivered in cobalt-alloyed steel grades, such as M35 = DIN 1.3243 and S390 Powder Metallurgy Steel. These blades are specifically suited for use in manual, semi-automatic and fully-automatic sawing operations. All blades are hardened to 64/65 RC, triple tempered and press quenched. This manufacturing method produces the flattest and straightest saw blade in the world today. The HSS slitting sawblades can be supplied in among other things bright, steam-treated, flash-chrome, titanium nitride, titanium aluminium nitride, titanium carbon nitride or chrome nitride coated design.

Hot and Friction Saw Blades for Metal Cutting - GSP Zborovice
Hot and Friction Saw Blades up to 2500 mm diameter are tools of high efficiency made from well proven steel plates with a tensile strenght of 850 bis 950 N/mm2. Friction saw blades are used for cutting of steel tubes and profiles by low working temperature, it means by material temperature up to 250°C. They are made from chrom-vanadium steel marked (DIN 1.2235) and they are heat-treated to reach the optimum ratio of tenacity and hardness, which is suitable for cutting of material with high circumferential cutting speed. The cutting principal consists in melting of material in cut place caused by special kind of teeth.
GSP - High Tech Saws, s.r.o. can manufacture these tools with taper of hollow ground. Choice of flange diameter, number of teeth, central bore diameter, thickness, driving holes number and diameter is possible. Hot and friction slitting saw blades are used for cutting slabs - square billets - plates - tubes ? profiles. Hot saw blades are used to cut metals with a temperature in excess of 850°C. When sawing metals below a temperature of 250°C, friction saw blades are used. Both sawing methods are a friction cutting. The friction heat in the cutting gap ae produces temperatures which bring the material in a soft, almost plastic condition. In order to clear debris from the tooth gullet a copiuos or heavy flow of coolant (preferably under high pressure) is essential for efficient cutting .
The required cutting speed is Vc=100-140 m/sec. Depending on the material to be cut the feed reached is Vf=80-2000 mm/min. The tooth geometry and tooth pitch are determined by the section and quality (analysis) of the material to be cut and the sawing machine. Heat treatment of the saw blades of 1200-1250 N/mm² (up to 1000 mm diameter) or hardening of the teeth up to Rockwell C 58 (up to 2500 diameter) gives an increase in both blade life and in number of cuts between resharpening.

The TCT sawblades are produced and controlled to the strick GSP manufacturing standards. The delivery program consists of 2 main groups, one range of TCT for ferrous and non-ferrous materials. The standard program can be supplied from stock, while special sawblades are produced to customer specifications.

Segmental saw blades
The segmental circular sawblades consist of a CrV steel disc on to which hardened toothed segments are mounted and secured by rivets. This principle makes it possible to repair a segmental sawblade after tooth or segment breakage by simple replacing one or more segments. Our current capacity range for segmental slitting saw blades is 10" diameter thru 120" diameter. Within this range we produce special diameters and thicknesses that offer our customers the widest spectrum of products.
The most commonly used tooth forms are HZ and BW. They are produced and controlled to the GSP manufacturing standards whereby precise sizing and close tolerances are guaranteed. The segmental sawblades are supplied as standard in high speed steel grade M2 = DIN 1.3343, but can also be supplied in cobalt-alloyed steel, such as M35 = DIN 1.3243 and M42 = DIN 1.3247.The segmental sawblades can be delivered in bright, titanium nitride, titanium carbon nitride, titanium aluminium nitride or chrome nitride coated design.
Alpha Cutter - Alpha Shear blades
Alpha cutters - alpha shear blades are the cut-off knives for cutting profiles and tubes. The cutting effect of alpha cutters is achieved with combination of high pressure and high speed. Burrfree cut of highest precision is achieved and the cut profile is free of deformation. Very short cutting times enable using these alpha cutters shear blades not only in stationary machines, but also in production lines during continuous cutting. In standard modification Alpha Cutters - alpha shear blades are made with PVD coating to prolong their lifetime, decrease friction coefficient and to avoid cool surfacing. These tools aren?t standardized at all, that?s why they are always tailored. For making the offer sending the drawing or sample is enough.
