B50125 Heavy-Duty Vertical Slotting Machine — Precision Keyways and Heavy Workpiece Machining

he B50125 vertical slotting machine is designed to bridge classic slotting capability with contemporary production demands. Built around a heavy cast-iron bed, the B50125 delivers high cutting force, precise micron-level table feeds and a large work envelope (Ø1400 mm table, up to 4,500 kg). It excels at precision keyways, deep internal cavities and complex internal contours for industries that process heavy, large workpieces.

Robustness, operator ergonomics and long-term reliability are at the core of the B50125’s design philosophy—ideal for repair shops and production lines that need a dependable slotter for tough materials and large geometries.

Key Technical Highlights
• Slotting envelope: 1250 mm maximum slotting length; slotting speed 4–30 m/min; return speed 7–35 m/min.
• Worktable: Ø1400 mm, max. loading 4,500 kg; longitudinal travel 1400 mm; cross travel 1120 mm; rapid travel 500 mm/min.
• Cutting capability: Max cutting force 24,500 N driven by a powerful 37 kW main motor.
• Precision feed: motorized/manual table feeds with micron-level adjustments; vertical and cross feed ranges offer fine control for repeatable keyway depths.
• Protection & maintenance: full-enclosure guards, automatic centralized lubrication and optional coolant systems for continuous safe operation.

Why B50125 Matters (Value Propositions)
• Heavy-duty power: 37 kW motor and 24.5 kN cutting force enable deep cuts and hard material removal without stall.
• Large-piece handling: Ø1400 mm table and 4.5 t capacity let you machine rings, flanges, gears and housings that many benchtop slotters cannot.
• Repeatable precision: fine feed ranges and precise return control produce accurate keyways and internal profiles across long production runs.
• Operator-centric: centralized controls, quick-clamp fixtures and clear dials reduce setup time and operator fatigue.
• Low total cost of ownership: robust castings, protective enclosures and automatic lubrication reduce downtime and maintenance costs.

Target Applications & Industries
• Gear and transmission manufacturers — precision keyways and spline seats.
• Heavy equipment & construction machinery — large shaft housings and bushing bores.
• Power generation & turbines — coupling flanges and internal seal grooves.
• Shipbuilding & marine components — rudder stocks, stern tube housings, large valve seats.
• Repair & refurbishment centers — remanufacture of worn keyways, reconditioning of large parts.

Practical Notes for Buyers
• Fixturing: for best accuracy on large rings, use multi-point supports and dedicated quick-clamp rigging.
• Material adaptability: with suitable high-performance tooling, B50125 handles cast iron, forged steels and many heat-resistant alloys.
• Optional upgrades: CNC indexing, hydraulic clamp tables, coolant filtration and heavy-duty tool posts are available to adapt the machine to production workflows.
