ALMe Lathe

Introducing the ALMe

The ALMe, with its lower machine height, touch-screen interface and accessibility, ensures compliance with the ergnomic requirements of the users and offers a good overview and easy access to all tools. The touch-screen technology enables the operator to work in an intuitive and efficient way. Superior lens surface quality, precision and productivity are the much valued and given features of all types of DAC lathes and the ALMe does not disappoint.

Precision air bearing spindles and slides are the main pre-requisites for achieving superior surface quality for contact lenses and intra-ocular lenses.
The DAC compact tool holders and the latest in DAC software for managing multiple tool functions provide the best opportunity to make the most of the large tool plate on the ALMe, in order to produce highly individual, non-rotationally symmetric lens designs.

Whether you want to make less volume of polish-free, highly complex surfaces or high volumes of classic lens designs, the options for the ALMe offer you all of these possibilities.

The well known ALM with its higher granite is still available for those who want to have a matching look with their already existing machines in the lab.
