Product Introduction

WULI WB-MF Series 70Bar CNC VFD High-Pressure Coolant System | Spindle Center Through TSC | For Neat Oil

WULI WB-MF Series High-Pressure Spindle Center Through Coolant System (70 Bar / 1000 PSI)

【Engineered for Neat Oil / Straight Oil】70 Bar Industrial High Pressure ✕ Air-Cooled Temp Control ✕ 7.5HP Smart VFD Energy Saving ✕ 7" Touchscreen HMI

The WULI WB-MF Series High-Pressure Coolant System (WB-2030MF & WB-2040MF) is custom-engineered specifically for neat oil (straight oil) machining environments. Powered by a 100% Taiwan-made, low-vibration ceramic plunger pump and an integrated air-cooled heat dissipation system, it consistently delivers up to 70 Bar (1000 PSI) of high-pressure flow. Its proprietary non-return thermal management design prevents oil heat accumulation during recirculating, solving critical 24/7 continuous production challenges like chip clogging, thermal tool damage, and workpiece distortion.

Key Engineering Advantages

Smart VFD Energy Savings: Dynamically adjusts motor speed by tool orifice, cutting power consumption by up to 76%.
Air-Cooled Temp Control: Purpose-built active cooling for neat oil reduces chiller loads and operational costs.
Non-Return Heat Suppression: Prevents oil overheating during idle cycles to maintain coolant viscosity and machining accuracy.
Clean Tool Change System: Automatic pressure relief and drip-free design protect spindle indexing and workshop cleanliness.
7-Inch Smart HMI: Supports multi-channel M-codes, dry-run protection, and automated filter clog alerts.
Precision Ceramic Pump: Taiwan-made ceramic plunger pump delivers ultra-smooth, low-noise operation (under 80 dB).

VFD Energy ROI Analysis (Up to 76% Energy Savings)

Conventional fixed-speed systems run at 100% full load regardless of tool nozzle diameter, constantly dumping excess energy into the oil as heat. The WB-MF VFD System modulates pump speed on-demand to slash shop-floor electricity costs:

Machining Scenario / Nozzle Specs	Fixed-Speed Model	WULI Smart VFD Model	Power Savings
Low Flow Demand (8 L/min \| Single Ø2mm Nozzle)	6.1 HP (Est. US$2,202 / year)	1.4 HP (Est. US$527 / year)	Save 76%
Medium Flow Demand (17 L/min \| Dual Ø2mm Nozzles)	6.1 HP (Est. US$2,202 / year)	2.8 HP (Est. US$1,005 / year)	Save Over 54%

* Calculation Basis: Estimated based on 10 operating hours/day, 30 days/month, 360 days/year at US$0.133 per kWh. Actual power savings vary depending on workpiece material, nozzle orifice, and site conditions.

Quantifiable Production Benefits

Tight Dimensional Accuracy: Dual-action thermal management (air cooling + non-return circulation) eliminates spindle growth and workpiece thermal expansion.
Extended Tool Life: 70 Bar targeted fluid delivery breaks through the vapor barrier directly at the cutting zone, reducing micro-chipping and thermal shock on carbide inserts.
High-Speed Deep Hole Evacuation: Instantly flushes stringy chips out of deep cavities, preventing tool re-cutting and enabling reliable unmanned lights-out manufacturing.
