Thanks to its optimised design, we reduce wear on key components.

WT
Highlights

Faithfull to the cross slide classic concept, yet guaranteeing top results

We have managed to maintain the classic advantages of cross slide machines, without sacrificing quality, thanks to the attention to every design detail:

  • Minimised footprint
  • Stationary parts (no unnecessary movements)
WT
Highlights

Efficiency starts before the part is even put on the machine

The WT is very easy to operate and to change references, saving time and minimising human error:

  • Self-calibrating gauge
  • Mobile tailstock
  • Quick connection outlets
  • Intuitive software and large screen
  • Ergonomics: Integrated platforms for operator safety and good access to the work area
WT
Highlights

Experts in grinding different materials

  • Grinding of all types of coatings (HVOF, chrome, etc.)
  • Innovative system for conditioning vitrified diamond wheels

Control software
Highlights
MDM: Automatic in- and post-process gauge

Prior to machining

  • Measures the oversized material on the part to ensure it is machinable

  • Ensures that the part was assembled properly and the machining program is free of dimensional errors

The data it outputs

  • Automatic metrological reports with dimensional and geometrical measurements
  • Roundness, radial run-out, cylindricity, concentricity, coaxility, diameters, discontinuous diameters etc.
  • Scanning for slender parts and back-and-forth machining 

How the data is displayed

  • You will be able to evaluate the behavior of the process thanks to continuous 3D visualizations
WT
01

Measures and certifies in/post-process, saving machining time and avoiding scrap

02

Dimensional tolerances are guaranteed from the first part in IT3 up to diameter 80 mm and IT2 from 80 mm onwards

03

Fully integrated into DoGrind+ for easy operation and handling of the meter

Technology
For heavy duty grinding, every detail matters
Wt technology
Grinding spindle heads

Mounted on proven ultra precision bearings, grease packed for life, and pre-load calculated for the maximum running accuracy and optimum stiffness under the heaviest operating conditions.

Machine structure
