Four spindle lines covering every machining application — from 10,000 RPM coupling spindles for standard VMC work, to 80,000 RPM ultra-high-speed units for PCB and dental, to 75 kW heavy-duty DGZX spindles for titanium and aerospace. All supplied, installed, and supported across India by Built Forge India.
Ultra-high-speed spindle line for PCB drilling, dental milling, graphite electrode machining, and precision optical work. Available in four diameter classes.
Heavy-duty spindle series for high metal-removal machining in titanium, Inconel, hardened steel, and large aluminium structures. HSK-A63 and HSK-A100 interfaces.
Direct-drive turning spindle for CNC lathes and Swiss-type machines. C-axis capable for turn-mill applications. GZC series handles Swiss bar work from 12–32 mm diameter.
Built Forge India supplies four Haozhi spindle lines: Coupling Spindles (BBT30/40/50, 10,000–24,000 RPM) for standard VMC and HMC applications; High Speed Cutting Spindles (Ø62–120 mm, up to 80,000 RPM) for PCB, dental, optical, graphite, and medical machining; DGZX High Performance Spindles (Ø150–280 mm, 22–75 kW, HSK-A63/A100) for aerospace and heavy-duty machining; and Motorized Turning Spindles (A2-4 to A2-8, 5.5–30 kW, 3,000–6,000 RPM) for CNC lathes.
Haozhi high-speed cutting spindles use P4-grade angular contact bearings, oil-air lubrication, and integrated temperature sensors feeding thermal displacement compensation. These features keep spindle runout below 1 µm and maintain accuracy across long production runs even at 80,000 RPM. The Ø62 model produces 2.5 kW at 80,000 RPM — enough for PCB drilling, dental milling, and graphite electrode machining.
Haozhi coupling spindles are compatible with Fanuc, Siemens, and Mitsubishi CNC controllers. The spindles use standard analog or digital speed command interfaces and include integrated encoder feedback, making them straightforward to integrate into existing machining center control architectures. Confirm your controller and drive system when enquiring so we can advise on the correct cable and parameter configuration.
The DGZX series is Haozhi's heavy-duty machining spindle line for high-metal-removal applications — titanium, Inconel, hardened steel, and large aluminium structures. With HSK-A63 or HSK-A100 interfaces and up to 75 kW (DGZX-28010), these spindles handle cutting forces that would cause vibration or deflection in standard coupling spindles. Choose DGZX when your application involves heavy cuts, hard materials, or large-diameter cutters on horizontal or vertical machining centers.
Yes. Built Forge India provides technical datasheets, parameter setup guidance, and after-sales support for all Haozhi spindle lines we supply.
