Machine Base
Lynx crank and cam grinders line has been developed using sophisticated 3D modeling programs and FEM analysis in order to optimize the rigidity of the cast iron base and better dampen vibrations.

• Unique one piece of cast Iron base.
• Optimized design for best damping characteristic.
• Very high strength and rigidity.
• A system for thermoregulation of the base ensures maximum dimensional stability.

Wheelhead

• Lynx crank and cam grinders line features a motorized spindle with an integral direct drive. Direct drive guarantees a compact construction and improved dynamic rigidity.
• Fully automatic balancing system and vibration detector for best cutting condition of the grinding wheel, higher accuracy and quick changeover.
• Linear motor technology with direct drive of the X axis (reciprocating movement of the wheelhead) resulting in improved accuracy and higher rigidity of the hydrostatic drive train (no transmission errors and wear effects).
• Full digital drive technology and a high resolution glass scale guarantee excellent synchronization characteristics, fast and accurate positioning, and high dynamics for rapid wheelhead and table movement.
• Liquid cooled drives for best heat dissipation and zero contamination.
• Rolling guides for high rigidity even in the most severe applications.
• Linear encoder at the X axis resulting in min command increment of 0.1µ.

Grinding wheels

Based on type of grinding Linx 2000can be fitted with:
• Conventional grinding wheels peripheral speed up to 35m/s, ideal for the production of small batches.
• Sintered ceramic grinding wheels-speed up to 63m/s offering higher resistance to wear and providing high removal capacity suitable for large size batches.
• highly productive CBN (cubic Boron Nitride) grinding wheels-speed up to 120m/s-for maximum machining capacity , tighter tolerances and particularly suitable for series production.

Workhead

• Chatter free grinding produces a perfect surface quality. We have designed a motorized spindle to achieve this with a direct drive to the C-axis.
• Direct drive of the workpiece spindle guarantees a compact construction, improved accuracy, reliability and higher rigidity of the drive train (no transmission errors and wear effects).
• Full digital drive technology and a high resolution rotary encoder guarantee excellent synchronization characteristics and high dynamics.
• Liquid cooled drive for best heat dissipation and zero contamination.
• Rolling guides for high rigidity even in the most severe applications.
• Encoder at the C axis resulting in min command increment of 0,0001 deg.
• Spindles with manuals clamping, automatic clamping and automatic clamping by means of retractable jaws in order to satisfy any possible grinding need.

Tailstock

• Optimized dimensions and solidly bolted on the table for maximum rigidity.
• Slide mounted tailstock with 50mm stroke is able to accommodate complete workpiece families without the need to re-set.
• It features a hydraulic quill retraction by foot pedal for easy workpiece clamping.
• Rotating tailstock with rolling bearing, motorized tailstock and fixed tailstock for concave cams grinding are available.

Work-table

• Linear motor technology with direct drive of the Z axis resulting in high dynamics, improved accuracy, higher reliability and rigidity of the drive train (no transmission errors and wear effects).
• Full digital drive technology and a high resolution linear encoder guarantees excellent synchronization characteristics, fast and accurate positioning, and high dynamics.
• Min command increment of 0.1µ.
• Linear rolling guides ensure higt rigidity even in the most severe applications and prevent the "backlash" phenomenon typical of hydrostatic systems.

Optional Equipment

• Wide range of "follow down" hydraulic steady rests to accomodate shaft diameters from 20 to 125 mm.
• Marposs measuring device for "in-process" control of main bearings, crank pin diameters.
• A second Retractable wheelhead for grinding concave cams. It features direct drive motor which enables installation of grinding wheels with a diameters from 38 to 100 mm.
• A cartesian manipulator (gantry) enables automatic workpiece loading and unloading.
• A cooling and cooling-lubrication device.
