B50125 Vertical Slotting Machine: Precision Keyway & Internal Form Machining Redefined

Jul 24, 2025 Leave a message

Engineering Breakthroughs: Where Power Meets Precision

Designed for mega-component machining, the B50125 vertical slotter delivers industry-leading 1250mm ram stroke and 350KN maximum cutting force – solving critical challenges in energy, marine, and heavy machinery sectors. Its reinforced double-wall column (HT300 cast iron) absorbs vibration at 4.5g acceleration, enabling ±0.015mm accuracy on hardened steels up to HRC55.


5 Core Technological Advantages

1. Hydraulic Power System: Intelligent Force Control

Variable-Displacement Pump: Automatically adjusts oil flow (12~180 L/min) based on cutting resistance, reducing energy consumption by 30% vs. fixed pumps.

Dual-Cylinder Ram Drive: Eliminates slip during reverse stroke, maintaining 0.02mm/m straightness over full travel.

2. Rigidity-Optimized Structure

Pre-Tensioned Guideways: Turcite-B coated slides with forced lubrication, wear life >100,000 hours.

Rotary Table Options: Manual 1600mm Ø or CNC-indexing 2000mm Ø (±5 arc-sec repeatability).

3. Smart Operation Interface

Feature Benefit
Programmable Stroke Adjustment Change ram length in 0.1mm increments without mechanical stops
Collision Avoidance System Infrared sensors halt operation if tool deflection >0.3mm
Quick-Tool Clamping ISO 50 taper toolholders change in <45 seconds

4. Industry-Specific Tooling Kits

Turbine Keyway Package: Carbide-tipped tools for HRC47+ steam turbine rotors

Internal Gear Module: Helical guide for 8-module gear slotting

Deep Spline Adapter: 800mm extended rams for excavator drive shafts

5. Maintenance & Safety

Centralized Lubrication: Automatic greasing of 23 critical points every 2 hours.

Emergency Dual Brakes: Halts ram in 0.15 seconds during power failure (EN 693 certified).
