The Topsfield Town Library can trace its origins back to Topsfield’s first library, the Topsfield Library Society founded in 1794 (Panella 2). Formed by eighty residents who paid twenty shillings each towards the purchase of books, the first 68 volumes were purchased and kept in a bookcase. The bookcase was kept at the home of the current librarian, usually the pastor of the church or a physician. Books were circulated the last Monday of every month. This bookcase and its original volumes are on display in the periodical room of the Topsfield Town Library today.

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.

GSP - High Tech Saws, s.r.o., resident in Zborovice, is a traditional cutting tools (slitting saw) producer. The beginnings of the manufacture date back to the year 1948 when the Pilana company established its branch there and started producing metal cutting circular saw blades from the very beginning. All produced tools were delivered under the name PILANA until 1992, SCHULER PILANA until 1999 and are now known as GSP- High Tech Saws.

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.

Circular saws in both high speed and super high speed steel suitable for goldsmith's cutting and machining purposes. The saw blades are all hollow ground (with hub) and the entire range is executed with tooth pitches finer than 1 millimetre.

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.

Circular saws in both high speed and super high steel suitable for cutting tubes sized ø 10 mm - ø 325 mm, with wall thickness ranging 2 mm - 10 mm, in both standard steels and high alloy steels (stainless). The saw blade range is ø 63 mm, ø 68 mm and ø 75 mm. Blade thicknesses are 1,2 mm, 1,6 mm and 2,0 mm and the tooth form is "Bw".

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 tungsten carbide tipped sawblade (TCT) consists of a CrV steel disc to which carbide tips are brazed. Company GSP produces TCT sawblades in diameters from 150 to 2000 mm in various designs. 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.

HM carbide tipped circular saws suitable for cutting-off pipes, profiles and solids in light alloys (aluminium etc.) The toothing presents a pre-cutter and a finishing tooth, with a positive angle (12?) for solids cutting and a negative angle (16?) for pipes and profiles cutting. Available with a 32 mm central bore and 2/11/63 pinholes. On request we can manufacture the blades with central bores of 25,4 - 30 - 40 and 50 mm.

The Topsfield Town Library serves a vibrant community of more than 6,000 residents.  The Library is a community center that hosts art displays, author visits, workshops, and frequent children’s story times.

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 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.

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.
