For highly efficient processing, the wheel dressing, workpiece grinding, and inspection can be performed in one setup. The TECHSTER series of machines come in many different sizes to accommodate a wide range of workpiece sizes.

 

Features

Proprietary low-center-of-gravity frame for high accuracy grinding

  • The integrated high rigidity T-shaped bed, C-shaped column structure and crosswise overhangless structure ensure high straightness accuracy.*1
  • Integrated T-shaped bed
    Integrated T-shaped bed

Environmental-friendly non-hydraulic ECO machine*2

  • The fully supported V-V slide way table is driven by a ball screw to enable high accuracy grinding at both low and high speeds. The non-hydraulic design reduces CO2 emission by 80% resulting in low environmental impact.
  • Capability of grinding concave forms and tapered profiles
    Capability of grinding concave forms and tapered profiles

Machine design with both operability and safety

  • Easy programming is enabled by the computer-based NC operation panel*3 and availability of three enclosure types*4 assure both operability and safety for operators, which increases grinding efficiency.

Wide variety of applications for shorter setup and grinding time

  • For higher productivity, profile measuring is performed on the machine using a CCD camera*5 coupled to interactive software and a variety of available dressers.

Multi-form grinding capabilities

  • Capable of many unique grinding cycles including taper and crown grinding*6

Formed wheel dressing

  • Several optional dressers are available including a swiveling rotary dresser*5. The on-board digital vision system assures a high accuracy on the form profile.
