Diamond Turning Machines | IL300

The IL300 is the leading ultra-precision diamond turning machine for high productivity, high flexibility optics manufacturing. It was designed to “drive productivity in ultra-precision technology” with consequently integrated submicron accuracy zero-point clamping systems, a stainless-steel enclosure and a high dynamic light weight construction for advanced dynamics. Applications cover standard diamond turning, free-form and micro structure generation as well as diamond turning of steel and infrared materials with ultrasonic assistance (ILSONIC).

Key Features

NanoGrip

Our NanoGrip zero-point clamping system interface allows for submicron repeatability in exchanging tools, sensors for in line metrology and work pieces with only a few seconds. It’s a fundamental feature for the leading-edge productivity of Innolite´s ultra-precision machines.
Individual pallets with four index positions for rotating at 90° angular steps are the exchangeable interface for the chucks mounted and aligned at the spindle (for work piece exchange) and at the Z-slide (for tool and sensor exchange).
Due to it´s robust design, turning operation of up to 5.000 rpm is supported on the spindle side. With a vacuum chuck adapter provided by Innolite, standard diamond turning functionality meets high productivity in next generation optical manufacturing.

Innolite - Ultra Precision Machine Tools - IL600

Key Features

Overdrive

The Innolite Overdrive is an ultra-high dynamic free-form and micro structure generator for diamond turning. It uniquely combines the advantages of slow slide and fast tool turning for advanced diamond untrue machining. Its linear motor driven hydrostatic slide with a moving mass of only 3 kg compares to the damping and the stiffness of a standard ultra-precision axis ensuring superb surface finish compared to an aerostatic fast tool servo. However, the dynamic reaction force during high dynamic motion is significantly lower and corresponding achievable dynamics are much higher compared to conventional slow tool turning. In terms of control system integration, the Overdrive can be programmed as a standard CNC axis as well as with the Innolite DirectDrive 2D or Direct Drive 3D.

Software for Generating Optics Manufcaturing Jobs | ILCAM

ILCAM is the programming platform for all Innolite diamond and center turning machines. It is designed to create high quality production jobs for advanced optics manufacturing, consisting of pre-machining data analysis, referencing routines, machining programs, measurement cycles for quality assurance and integrated quality documentation. It allows for conventional optics manufacturing, free-form and micro structure generation as well as for combined optical surfaces. Different from conventional CAD/CAM software the fully automated integration of optics characterization routines is of highest value during production. With its functional spectrum, ILCAM is a unique platform for ultra-precision machining.
