eSX 400 5-Axis Lens Grinding Machine: 5-400 mm Optics
-
Overview
eSX 400 Overview
The eSX 400 lens grinding machine has 5 controllable axes: X, Y, Z, B & C with up to 5 axes of simultaneous movement. This configuration is comparable to the eSX 300, but features a larger work spindle (C-Axis), allowing optical manufacturers to grind optics 400mm in diameter (or as large as 450mm depending on geometry). The powerful Fagor 8065 CNC with user-friendly G Series software make the eSX 400 optical machining center an excellent choice for manufacturing spheres, aspheres, cylinders, freeforms and more.
Multiple advanced features on the eSX 400 help optical manufacturers achieve optimal results in terms of grinding efficiency, repeatability and surface quality after grinding:
- Better grinding: Stiff, heavy meehanite machine base to provide vibration dampening + spindle construction with high quality ceramic bearings
- Extensive part diameter range: Large work envelope with generous axes travels
- Faster set ups: Easy-to-use Graphical User Interface for precision optics with step-by-step process driven software (G Series)
- Full 5-axis machining standard: Capable of CAM driven manufacturing of off-axis, non-rotationally symmetric parts as well as coring operations
- High accuracy tool and work spindles: HSK 63 quick-change holders for less chatter
- Process consistency: Liquid cooled spindles
- Better process control: Direct drive spindles
- More cutting power: Integral high torque spindle motor
- Tooling flexibility: Accommodates a wide variety of tools, including ball tools
- Energy efficient: Servos turn off automatically
- Additional features available: Automatic tool and work piece probes, twin spindles, automatic tool changers, mist removal, and more
Maximize throughput of precision optics by implementing the capability of the eSX 400 into your manufacturing operations.
