As an upgraded high-power centrifugal barrel finishing machine, it boosts power and capacity based on the 40A model. Driven by a high-power motor, its finishing efficiency is 30% higher than the basic version, with an expanded speed range up to 170 RPM-ideal for medium-batch efficient processing.
Equipped with four thickened pentagonal barrels (50L capacity each), it increases single-batch output while ensuring processing quality. Reinforced bearings at the barrel-turntable connection enhance load-bearing capacity, delivering stable, vibration-free and noise-free operation at high speeds.
The barrel features a thickened cold-rolled steel outer body (impact-resistant & deformation-proof) and a high-wear polyurethane inner liner-40% more wear-resistant than the 40A model, suitable for grinding high-hardness metal parts.
Fully enclosed leak-proof barrel assembly supports customized multi-compartment liners, enabling simultaneous processing of multiple small parts without mixing or collision. Perfect for medium-batch, multi-spec precision components.
Integrated intelligent speed control system allows stepless speed adjustment from rough grinding to fine polishing with one key, saving manual setup time significantly.

Overall Structure (Upgraded from 40A)
Reinforced design includes thickened upper cover, heavy-duty base, enhanced barrel turntable assembly, intelligent electrical cabinet, and large-capacity receiving trough-optimized for long-term continuous operation with extended service life.

• Upper Cover: Thickened steel structure with detachable ventilation baffles (easy cleaning/maintenance); double-reinforced protective sliding door with imported travel switch (higher sensitivity & safety).
• Heavy-Duty Base: Thickened channel steel welding with shock-absorbing rubber pads (reduces vibration/resonance/noise); thickened motor fixing plate with dual-screw adjustment (precise & stable belt tension control).
• Enhanced Barrel Turntable: Cast steel turntable (deformation-resistant & wear-proof); dual-motor worm reducer for barrel tilting (stronger power, faster unloading); stainless steel buckles + food-grade silicone gaskets (rust-proof, leak-proof).
• Intelligent Electrical Cabinet: IP54 dustproof & waterproof rating with built-in cooling fan; added speed display screen (real-time process monitoring).

Working Principle
Adopts "revolution + rotation" dual-power grinding. The 11KW high-power motor drives the cast steel turntable for high-speed revolution via pulleys. High-precision helical gears ensure efficient, low-noise transmission, driving four barrels for reverse high-speed rotation-generating stronger dual centrifugal force than the 40A model.
Workpieces and abrasives form a high-density grinding zone under centrifugal force, achieving all-round, dead-angle-free grinding. Rapidly completes chamfering, deburring, and fine polishing with higher efficiency and better surface finish than the basic version.

Equipped with imported intelligent inverter + PLC speed control module (speed accuracy ±1 RPM). Supports multi-stage speed presets-preprogram rough/medium/fine grinding parameters for semi-automatic operation, reducing manual intervention.

User-friendly control panel with emergency stop button, speed display, inching control, and mode switch-easy to operate even for beginners.

Upgraded multiple safety protections: two-way travel switch interlock, motor overload/overheat protection, voltage stabilization protection (automatic shutdown in abnormal conditions); barrel tilting limit protection (prevents mechanical failure from over-tilting).

Installation Requirements
1.Place on a level concrete floor (load-bearing ≥1000KG/㎡) with dedicated shock-absorbing rubber pads (ensure horizontal & stable operation).
2.Test motor winding insulation resistance with a 500V megohmmeter (≥0.5 MΩ; dry if unqualified to avoid leakage).
3.Connect to 380V three-phase industrial power (voltage stability: 380±10V); ensure turntable rotates clockwise (top view) with reliable grounding (ground resistance ≤4Ω).
4.Conduct 5-minute no-load test before use (check for abnormal noise/vibration).

Later Adjustment
1.Inspect motor belt wear/tension every 300 operating hours (adjust via dual-screw mechanism; replace worn belts promptly).
2.Tension barrel tilting chain via tension pulley (no need to move reducer bracket-easy operation).
3.Regularly tighten barrel positioning screws (ensure coaxiality & uniform grinding).

Operation Steps
1.Power on, select manual/automatic mode. In manual mode, adjust barrel to 10° forward tilt via inching switch, loosen stainless steel buckles, and remove the cover.
2.Pre-treat workpieces (degrease/derust); load workpieces and abrasives at 1:2.5 ratio (65%-70% of barrel capacity). Add special grinding agent and pure water (2-3cm above materials); fasten the cover tightly (ensure gasket compression).
3.In automatic mode: preset speed & time, then start. In manual mode: adjust speed directly. Shut down every 90 minutes for water change (prevents liner aging from high temperature).
4.After grinding, tilt the barrel via inching switch to discharge materials into the receiving trough (preliminary separation via graded filter).

Daily Maintenance
1.Lubricate all bearings with high-temperature wear-resistant calcium-based grease after 400 operating hours; clean bearings regularly (prevent dust/abrasive damage).
2.Clean barrel interior & receiving trough daily; dry the inner liner (avoid corrosion from residual grinding fluid); replace aged/damaged gaskets promptly.
3.Clean electrical cabinet weekly (remove dust, check terminals/fan); calibrate inverter/PLC parameters monthly (ensure precision).
4.For long-term storage: clean abrasives, dry the machine, rust-proof metal parts, and power off with dust protection.

Suitable for chamfering, deburring, and fine polishing of medium-high hardness metal parts (stainless steel, high-carbon steel, titanium alloy, aluminum alloy) in hardware, auto parts, aerospace, and precision mold industries.

Ideal for medium-batch, multi-spec precision special-shaped parts, shafts, and gears-supports simultaneous processing of multiple parts to significantly improve efficiency.
