KVD Series

The KVD Series vertical double-disc grinders are engineered for precision, productivity, and reliability across demanding industries such as automotive, bearings, home appliances, and communications. Equipped with advanced Electro-discharge truing (E-dt) technology, these machines deliver non-contact truing that maintains the integrity of metal-bonded diamond wheels while ensuring superior accuracy and surface quality. High-precision grinding is supported by large, angular thrust and ultra-precise roller bearings in the wheel spindle, while the slim column design allows for efficient, space-saving integration with automation and gauging systems.

Built to Deliver Precision & Flexibility

The KVD Series offers a full lineup of vertical double-disc surface grinders designed to deliver precision, flexibility, and productivity across industries such as automotive, bearings, aerospace, appliances, and more. From compact models like the KVD200 and KVD300WII, which excel in small-part grinding and difficult material applications, to mid-size machines like the KVD350 and KVD450II, which provide high-production capability with minimized thermal distortion, the series ensures efficient and reliable performance for a wide range of component sizes and materials.

For larger and heavier parts, the KVD580 and KVD760 deliver advanced features such as adjustable spindle rigidity, CNC-controlled wheel shaping, automatic height setting, and AE sensors for precision dressing—all while maintaining easy side-access wheel changes. Together, the KVD Series provides manufacturers with a scalable grinding solution, supported by advanced feed systems (through-feed, oscillation in-feed, rotary carrier, and swing arm types) to meet diverse application needs with accuracy, consistency, and automation readiness.
