Safe clamping during high-performance milling

HB Mill Chuck

Strong clamping, easy handling and optimum radial run-out – this is how the new mill chuck convinces users. MAPAL produces the location bore with a tolerance in the single-digit µm range. This is more precise than in the past. As a result, the tool has a significantly reduced radial play, the radial run-out is considerably better.

A spring element in the connection compensates for the large tolerance on the HB clamping surface of the tool. This is how it produces the defined form fit between tool and connection. Coolant channels parallel to the axis in the clamping range also ensure an improved coolant supply.

Due to the two-part clamping element, handling the Mill Chuck is extremely easy. It reduces the tightening torque while maintaining the same clamping force. Users can safely clamp the tool in the connection by hand.

In detail:

The picture shows the optimum coolant supply for the HB surface chuck Mill Chuck from MAPAL.

Optimum coolant supply

  • Decentralised coolant supply channels
  • Use of standard tools without internal cooling
  • Tool life improved thanks to optimal cooling

In the illustration of the HB Mill Chuck surface clamping chuck from MAPAL, the picture focuses on process-safe tool clamping.

Process-reliable tool clamping

  • High clamping force thanks to two-part clamping element
  • Maximum tightening torque 50 Nm (with diameter of 32)
  • Process-reliable clamping through self-locking

The picture illustrates how the HB surface clamping chuck Mill Chuck from MAPAL ensures a defined milling cutter positioning.
