Design Features

  • Fast tool servo designed specifically for cutting toric lens profiles
  • 4000 microns of total travel
  • Compact drive technology
  • Non-proprietary, open programming syntax
  • High-performance in a cost-effective package
  • Reaction mass design minimizes vibration-induced errors on lens turning platform
  • Small size and low moving mass enable higher machine throughput

The TLG (Toric Lens Generator) is a single-axis, high-speed oscillating tool optimized for the production of toric lens profiles. Competitive oscillating tools are designed to manufacture multi-faceted lens profiles in metallic materials. As such they are over-designed for turning toric profiles in materials commonly used in the manufacturing of IOLs and contact lenses. This “excess” capability results in a system that is overpriced, oversized, and unnecessarily complex to program.

The Aerotech TLG was developed with the primary purpose of creating toric lens profiles in IOL and contact lens materials rotating at speeds of up to 6000 rpm. By limiting the application scope of the product, Aerotech is able to develop a smaller, less costly solution than competitive products. The TLG is equipped with an advanced reaction-mass design that virtually eliminates vibrational errors that would otherwise be introduced into the lens manufacturing platform, thus resulting in a high-quality lens surface finish. Furthermore, a tool micro-height adjuster allows for ±500 µm of adjustable range using a very-high-resolution adjusting mechanism that greatly reduces or eliminates tool centering errors resulting in reduced polishing time.

Open Programming Language

The TLG and its supporting drive technology are designed to work with Aerotech’s A3200 Automation platform, a scalable networked system capable of supporting up to 32 axes. The A3200 system is programmed directly in industry standard G-code or with AeroBasic™ commands that provide access to capabilities beyond standard machine-tool syntax. Tool paths are created using the standard toric “Z” height algorithm which is completely accessible to the user. The algorithm can be customized to support an aspheric base profile or non-orthogonal major and minor toric axes.

Compact Design

The TLG uses Aerotech’s Ndrive-FLS (Fast Linear Servo) drive technology. The linear power stage reduces following errors during the direction reversals of the tool resulting in submicron-level form errors. At 100 x 223 x 174 mm in size the Ndrive-FLS is significantly smaller than competitive drive products allowing it to be mounted inside the machine base, reducing the overall size of the machine.
