The WINSTAR SP forming grinder is the highest level model. It delivers short lead times and unmatched grinding precision required in all technology driven markets, including medical, semiconductor and electronics.

This future is realized in the WINSTAR SP (V-spec) which provides CCD camera based on board measurement for form shapes as well as an eco-friendly NC controlled ball screw / direct longitudinal table drive. Moreover, while achieving automatic measurement with a CCD camera and compensating processing, [WINSTAR SP(V-spec)] has pursued further high performance and high precision with its space-saving body with an innovative design combines the latest technologies, and supports the business solutions of our customers to make it truly worthy of its name, “SP = Small & Precision”.

V SPEC Vision Sensor: CCD camera measurement system ,The CCD camera and original software can measure shapes on the machine.There is no need to remove the workpiece, reducing processing time, and eliminating handling errors when measuring.

AMADA proprietary column type three plane independent structure: Its foundation is a T-bed with an elongated slide and column base. High static accuracy is assured through an independent moving column design that provides excellent operability. In addition, the V-V slideway is fully supported eliminating overhang and maintaining superior straightness accuracy.

Ultra-low vibration spindle motor achieves ultra mirror surface finish capability: The grinding spindle achieves ultra mirror surface finishes, through a class V1 ultra low vibration, oil cooled spindle motor, equipped with an extra oil bath cooling function as standard equipment which provides great thermal stability.
