CNC Double Grinding Head Cylindrical Grinding Machine

Dual Grinding Wheel Configuration — Two wheels (A: Φ750x100x305, B: Φ750x75x305) are mounted on the same wheelstock, allowing different grinding operations to be completed in one setup without wheel changeovers — reducing cycle time on multi-diameter shafts.

Long-Shaft Capacity — Available in four grinding-length configurations (1000/1500/2000/3000mm) with center distances up to 3100mm, covering everything from short spindles to long rollers within one machine series.

Heavy-Duty Load Rating — Supports workpieces up to Φ500mm in diameter and 1000kg in weight, with a 540mm rotation diameter, suited to large industrial shafts and rollers.

High-Precision Servo Control — The worktable achieves 0.001mm drive resolution, while the transverse feed mechanism reaches 0.0001mm resolution with a 22Nm AC servo motor torque, ensuring stable, repeatable micron-level positioning.

Powerful, Stable Wheelstock — A 15kW spindle motor drives the wheel at up to 45m/s linear speed, with 400mm max movement, delivering consistent stock removal even on hardened, large-diameter workpieces.

Adjustable Taper Worktable — The worktable supports adjustable taper settings, enabling accurate taper and straight-shaft grinding on the same platform.

Proven Grinding Accuracy — Delivers roundness ≤0.003mm, cylindricity ≤0.008/1000mm, and surface roughness ≤Ra 0.32μm, meeting demanding finish-grade tolerances straight off the machine.

Zhejiang Quanshun Machine Tool Co., Ltd. specializes in CNC cylindrical grinding equipment engineered for heavy industrial applications. The MK-F50 double grinding head series combines a rigid machine bed, dual-wheel wheelstock, and high-resolution servo axes to help manufacturers reduce setup changeovers and improve grinding consistency on large, multi-diameter shafts. We offer configurable center distances, wheel sizes, and motor power to match specific workpiece requirements, backed by technical consultation, installation support, and after-sales service.

What does "double grinding head" mean on this machine?

The wheelstock carries two grinding wheels (A: Φ750x100x305, B: Φ750x75x305), allowing different grinding operations — such as different diameters or grinding stages — to be completed on the same setup without swapping wheels.

What is the maximum workpiece size and weight?

The machine grinds workpieces from Φ30mm to Φ500mm in diameter, with a rotation diameter of Φ540mm and a maximum workpiece weight of 1000kg.

What grinding lengths are available?

The MK-F50 series is available in four configurations with maximum grinding lengths of 1000mm, 1500mm, 2000mm, and 3000mm to match different shaft lengths.

What level of precision can this machine achieve?

The machine achieves roundness ≤0.003mm, cylindricity ≤0.008/1000mm, and surface roughness ≤Ra 0.32μm, with transverse feed resolution down to 0.0001mm.

Can the machine grind tapered workpieces?

Yes. The worktable features an adjustable taper type, allowing precise taper grinding in addition to straight cylindrical grinding.

Can specifications be customized?

Yes. Zhejiang Quanshun Machine Tool offers customization of center distance, wheel size, spindle motor power, and other parameters based on specific workpiece and production requirements.
