Rushan Shuangxing Machine Tool Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of double disk grinding machine in China. With abundant experience, our factory offer high quality equipment made in China with competitive price. Welcome to contact us for customized service.
Factories manufacturing thick circular metal components often rely on single-sided grinding equipment. Each blank requires two separate clamping cycles to finish both faces, which adds extra labor steps and introduces avoidable dimensional errors in parallelism and thickness consistency. Thick, high-hardness steel workpieces also demand consistent high torque for efficient stock removal; lighter-duty grinders lose geometric precision after hours of nonstop operation.
This SX150-12YL double disk grinding machine streamlines the workflow by processing both workpiece surfaces in a single fixture setup, removing repeated re-clamping and alignment work. Separate dedicated motors power spindle rotation, grinding head travel and wheel dressing respectively, distributing cutting loads to limit vibration transfer that compromises flatness accuracy. Its full-system 96kW power rating covers all operational auxiliary drives alongside the core grinding motors, delivering steady performance for round-the-clock heavy steel blank processing.

1. Spindle Assembly and Precision Feed Control
A solid Φ150mm spindle shaft delivers rigid rotational support during heavy stock removal, resisting bending deflection when machining thick metal blanks. The grinding head provides 130mm of vertical travel, creating sufficient clearance to mount interchangeable fixtures for blanks with varying thickness profiles.
A minimum feed step of 0.001mm enables precise incremental adjustment of cutting depth. Operators can complete aggressive rough stock removal first, then fine-tune feed rates for semi-finishing passes without transferring workpieces to separate equipment.
2. Full-System Multi-Drive Power Layout
Three core motor groups handle primary grinding and adjustment movements. The listed 96kW total power accounts for all core drive motors plus integrated auxiliary hydraulic, cooling and control system power components, while the primary mechanical drive breakdown is as follows:
- Dual 30kW spindle motors: Supply matched torque for simultaneous stock removal across both grinding disks on thick carbon and alloy steel blanks
- Dual 1.8kW feed motors: Maintain uniform linear travel speed for the grinding head assembly, holding consistent cutting depth across all workpieces in a batch
- Single 0.9kW wheel trimming motor: Executes routine abrasive wheel dressing to preserve stable cutting edge geometry over extended production runs
Segmented motor layout separates cutting loads and heat generation sources, preventing individual drive overload during multi-shift operation. This reduces wear on core moving assemblies and cuts unplanned maintenance downtime for production lines.
Suitable Production Environments and Workpieces
This double disk grinding system fits heavy-duty manufacturing facilities focused on circular metal component production, including large-scale bearing foundries, construction machinery component workshops, heavy commercial vehicle part suppliers and general heavy metal fabrication plants.
It is engineered exclusively for mass two-sided planar grinding of thick, large-diameter circular blanks, simplifying end-to-end processing workflows and lifting finished component qualification rates for 24-hour continuous production schedules.
Frequently Asked Customer Questions
Q: What component types pair best with the SX150-12YL model?
A: This unit is built for heavy circular industrial workpieces, including large load-bearing bearing races, mechanical connecting flanges and construction machinery disc components that demand precise parallelism on both planar surfaces.
Q: Why separate spindle, feed and trimming functions onto independent drive motors?
A: Isolated drive systems split cutting vibration and thermal load away from the main spindle assembly. This design mitigates spindle tilt and heat-induced deformation common on single-power grinding equipment, sustaining stable geometric accuracy through full daily production shifts.
Q: Why is the total system power listed at 96kW when primary mechanical motors sum to less?
A: The 96kW figure reflects the complete installed system power rating, which includes all primary grinding motors plus auxiliary power loads for hydraulic circuits, cooling units, control cabinet hardware and dressing accessories that operate alongside the main drive assembly during full machine operation. The spindle, feed and trimming motors represent only the mechanical grinding drives within this full power budget.
