The newly developed auto-measure function on the E46LTWA Presetter introduces a feature that is unique on this type of machine.

When “auto-measure” is performed, the spindle rotates at a speed that is calculated based on the peripheral diameter of the tool to ensure the cutting edge is captured with the highest level of accuracy.

E46LTWA is equipped with the original camera as on the E46LA model but with the addition of a secondary high-resolution swivel camera (60X magnification with, in addition, 2X and 4X digital zoom capability) to allow and facilitate detailed inspection and geometry functions from both the side and top of the tool profile. This additional capability is particularly useful not only for CNC machinists but also benefits tool manufacturers to precisely measure linear and geometrical features of the tool profile.

In addition to this, as the highest point of each individual cutting edge is approached, the software calculates the deceleration and acceleration of the spindle to ensure absolutely precise measurement of each and every cutting edge is achieved. This is unlike other machines in the marketplace that use one constant rotational speed based on a set tool diameter, by instead linking the auto-measure function of the Presetter to the diameter of the tool being measured.

  • Machine structure in high quality structural steel to provide increased stiffness with higher accuracy and rigidity.

  • Featuring an automatic measure function with a 22” capacitive touch screen.

  • Solid granite column and base to guarantee maximum accuracy.

Main Frame & Construction

Machine structure in high quality structural steel to provide increased stiffness with higher accuracy and rigidity. Solid granite column and base (increased substantially in size over previous generation models) to guarantee maximum accuracy.

Spindle System

A wide variety of tools can be pre-set utilizing interchangeable spindle cartridges rather than adaptors. This reduces the number of interface connections delivering accuracy across all spindle types.


Featuring an automatic measure function with a 22” capacitive touch screen. The screen layout is split into two sections, half displaying images of the current tool and profile, and the other allowing access to the existing software functions.
