Rotary knives and circular knives

Materials: rubber, leather, paper, isolation materials and plastics, non-ferrous metals and steel
Application: efficient cutting operation
Machine: processing machines
Characteristic:

  • usually manufactured from the following kinds of steel:
    • industrial knives made from DIN 1.3343 (HSS-Dmo5)
    • industrial knives made from DIN 1.3243 (HSS-Co5)
    • industrial knives made from DIN 1.2379 (K 110)
    • industrial knives made from DIN 1.2067 (100 Cr6)
    • industrial knives made from DIN 1.2080 (X210Cr12)
    • industrial knives made from DIN 1.4034 (X40Cr13)
    • industrial knives made from DIN 1.4112 (X90CrVMo18)
  • according to their various purpose of using our circular knives are heat-treated to hardness 56 - 64 HRC
  • in standard modification our circular knives are manufactured without surface treatment; some of our rotary knives can be treated with PVD coatings (e.g. TIN, TICN or TIALN) or with teflon
  • our circular knives are manufactured from diameter 20 mm to 600 mm
  • if these rotary knives are used in grocery (e.g. production of tinned vegetables or circular knives for cutting of deep-frozen products like fish, circular knives for meat etc.) such circular knives are manufactured from stainless steel
  • Since these industrial knives are manufactured only on request it is very important to specify the following data in client´s inquiries or orders:
    • diameter of the circular knife
    • thickness of the circular knife
    • central bore diameter of circular knife
    • driving pin holes diameter, number and pitch of the circular knife
    • kind of material which should be used for body of the circular knife
    • cutting edge variant of the circular knife
    • cutting geometry of the circular knife
    • cutting edge length of the circular knife
    • kind of cut material by the circular knife
  • The cutting edge industrial knife is not interrupted in the standard modification. It can be equipped with teeth similar to the teeth used on HSS circular saw blades for metal cutting or with quite specific tooth forms. Circular knives without teeth but circular knives with grooves, or circular knives with ripples on the cutting edge can be manufactured too.
  • Cutting edges of these industrial knives vary depending on the kind of material cut by the industrial knife. The following tabele shows the particular variants of edges we produce on our industrial knives.

In the product range of GSP - High Tech Saws, s.r.o. are also high-efficient cutting industrial knives manufactured on request which are generally known as circular knives. These rotary knives are used not only for cutting rubber, leather, paper, isolation materials and plastics, but also non-ferrous metals and steel. Cutting edges of these industrial knives are various according to the kind of cut material.

 

Following survey shows particular variants.

In the product range of GSP - High Tech Saws, s.r.o. are also high-efficient cutting tools manufactured on request which are generally known as circular knives. Circular knives in HSS-DMo5, HSS-Co 5%, K110, K190 PM and S 390 PM Steels are used not only for cutting rubber, leather, paper, isolation materials and plastics, cutting thin walled tubes, hoses, but also non-ferrous metals and steel.

Cutting edges of circular knives are various according to the kind of cut material. Applications of rotary knives are on semi and fully automatic machines. Our range spans from ø 20 mm through to ø 600 mm and the standard execution of all circular knives is HP-GRIND finish but readily available in our P.V.D. (Physical Vapour Deposition) coatings too. Company GSP manufactures also the highest quality food and meet processing rotary knives in the industry from 3" to 20" in diameter. 

We manufacture with the latest CNC grinding equipment to achieve up to 3 times longer knife life. We currently have a manufacturing capacity of 1" diameter thru 72" diameter, in various thicknesses. Raw material is available in M2, M42, D2 and A2 tool steels and can be provided to a wide range of hardnesses.

From a simple single bevel to a complex compound double bevel, GSP's superior craftsmanship guarantees an exactness unmatched in the industry. CIRCULAR KNIVES are made for many differing applications and industries, the following drawings give an idea of the forms available in the range 1? to 16? (25 to 400 mm) diameter.

Typical Industries include:

  • Circular knives for Automotive
  • Circular knives for Converting
