About Hydro Cutterheads

Hydro cutterheads are the long-time standard in precision tooling for high-performance moulders. Unlike conventional cutterheads that use mechanical clamping systems, hydro cutterheads utilize hydraulic pressure to uniformly secure knives along the cutterhead body. This advanced clamping method ensures concentricity, superior balance, and exceptional surface finishes at high feed speeds.

Ideal for applications that demand tight tolerances and premium surface quality, all at high speeds.—hydro cutterheads minimize vibration and significantly improve tool life. The even distribution of hydraulic pressure reduces stress on the knives, allowing for smoother operation and cleaner cuts, even with challenging profiles or hardwoods.

Another major advantage is ease of use. Knife changes are faster and more consistent, dramatically reducing setup time and the risk of human error. Operators benefit from a safer working environment, as the hydraulic system provides secure, reliable clamping without the need for manual torqueing or adjustment.

At Weinig Holz-Her, we offer a full range of hydro cutterheads tailored to your application and moulder specifications.

• Standard cutting angle 20°, or 12° for selected hardwoods that present tear-out problems.
• Maximum tolerance of concentricity (true running accuracy) 0.005mm (0.000197").
• Body of high-tensile steel.
• Hydraulic grease fitting and pressure release valve located on each side of hydro-head.
• Designed for use with 1/4", 5/16" or 3/8" thick knives with 16-60° corrugated back.
• Designed for WEINIG’s Axial Constant Setup System.
• Two-piece clamping sleeve ensures tolerance-free center clamping on spindles with or without keyways.
