1 TOOLS NEWS PVD coated Cermet grade for steel B194H Produces excellent surface finishes.

2 PVD coated Cermet grade for steel PVD coated Cermet grade for steel has excellent flank wear and fracture resistance. Due to the improved adhesion strength of the smooth substrate surface, 3025 gives excellent surface finishes, ideal for mass production of small parts. Ti-compound PVD coating provides excellent wear and welding resistance. Substrate surface provides excellent adhesion strength for the coating layer. Substrate with superior fracture and thermal shock resistance. High quality finishes at low speeds produces better surface finishes at low cutting speeds than competitors PVD cermet grades Conventional 200mm <Cutting condition> Work piece : S25C volution : n=398 min.-1 (Outer: vc=250 m/min.) Depth of cut : ap=1.5 mm Feed : f=0.15 mm/rev. Wet cutting 1 a: Inventory maintained.

3 Breaker system for steel cutting (Negative inserts) Application Tolerance Chipbreaker Features Cross Section M M M M M FH First recommendation for finishing carbon steel, 3 alloy steel and stainless steel Double sided chipbreaker. Stable chip control even at small depths of cut. FY First recommendation for finishing mild steel 3 Double sided chipbreaker. Effectively controls adhesive chips. Suitable for mild steel finishing. First recommendation for light cutting of carbon 4 and alloy steel Stable chip control in the light cutting range. The curved edge allows smooth chip discharge. SY First recommendation for light cutting of mild 4 Double sided chipbreaker. Effectively controls adhesive chips. Suitable for light cutting. First recommendation for medium cutting of carbon 5 and alloy steel Suitable for medium to light cutting. Breaker geometry suitable for copying and back turning. Cutting edge geometry for an optimum balance of sharpness and fracture resistance.

Corner strength is maintained to prevent abnormal fracturing. 5 Positive Insert First recommendation for light cutting of carbon and alloy steel Excellent cutting edge sharpness due to the large rake angle. Prevents chip welding of the insert to ensure good surface finishes. Optimised breaker realises a wide range of chip control. 5 Positive Insert First recommendation for medium cutting of carbon and alloy steel The flat land produces excellent wear resistance and superior fracture resistance. The wide pocket reduces vibration and chip jamming and also prevents increases in cutting resistance even at high depths of cut. 5 Positive Insert Carbon Steel Alloy Steel f (mm/rev) ap (mm) ap (mm) ap (mm) Carbon Steel Alloy Steel f (mm/rev) Carbon Steel Alloy Steel f (mm/rev) Nose Flank Nose Flank Nose 0.1 Flank 0.1 2
