Convex blades

by LUTZ BLADES

We have the hang of it

Convex blades with outward curved cutting edge are another specialty of LUTZ BLADES. The contour of the cutting edge in the shape of an arc is applied to the first as well as the millionth blade in a predictable and repeatable manner, thus ensuring consistently high quality.

Our experts will be happy to advise you so that you can quickly find your optimum combination of geometry, material, coating and hardness. We have prepared this form so that you can be forwarded directly to the right contact person. Four quick steps are all it takes - and you are in the best hands.

The wide range of materials

for our blades

Our product portfolio offers you blades in thicknesses between 0.06 - 3.0 mm and with final hardnesses between 40 - 85 HRc. You also have a wide choice in our material program:

  • Carbon steel
  • Rust-resistant, hardened steel
  • (HSS) High-performance High-speed Steel
  • Ceramic
  • Austenite
  • Bimetal
  • Carbide

The versatile coating program
for our blades

TiN (Titan-Nitrid)

Standard hard material with high wear resistance and relatively high coefficient of friction (against reference material steel approx. 0.4 to 0.7), usually gold-colored, safe application range up to approx. 300 °C.

TiC (Titan-Carbit)

Has lower wear resistance than TiN with significantly lower coefficient of friction (against reference material steel approx. 0.3 to 0.5), usually anthracite colored.

TiCN (Titan-Carbonit)

Intermediate coating material between the high wear resistance of TiN and the low coefficient of friction of TiC, relative position between TiN and TiC depending on the ratio of C and N, usually anthracite color.

TiAlN (Titan-Aluminium-Nitrid)

Has greater oxidation resistance than TiN with comparable coefficient of friction, usually anthracite blue.

ZrN (Zirkon-Nitrid)

With a wear resistance similar to TiN, but denser structure (morphology) than TiN and thus greater resistance to pitting under appropriate load, usually steel colored.

DLC (Diamond-like Carbon)

Has high wear resistance with low coefficient of friction (approx. 0.1 against reference material steel); susceptible to impact loads and high temperatures (between 100 and 300 °C depending on structure).

(PTFE) (Poly-Tetra-Fluor-Ethylen) – Teflon®

Teflon® non-stick coating (PTFE); due to the very low surface tension, practically no foreign bodies stick to the cutting edge, resistant to acids and alkalis; significantly reduced frictional resistance; the very low static friction allows jerk-free cutting (therefore very suitable for the medical sector); low wear resistance; not suitable for contact with sodium and at temperatures above 250 °C.

Color varnish

Applied over the entire surface, serves as a sorting aid for different material thicknesses and as corrosion protection.

Blueing / Blackening

Applied over the entire surface, light corrosion and starch protection, also serves as a distinguishing aid.

Customized quality
The LUTZ BLADES Rapid Prototyping
