Factories manufacturing heavy circular metal parts rely on grinding equipment that can hold tight geometric tolerances through endless high-volume shifts. Most standard grinders fall short when handling oversized, thick blanks: spindle deflection, vibration drift and inconsistent stock removal create batch-to-batch flatness and thickness inconsistencies that add costly secondary rework.
The high-precision surface grinding machine was engineered to solve these real-world production bottlenecks. Its extra-wide cast base and segmented multi-motor power layout cut down operating vibration drastically, while ultra-fine micro-feed tuning locks in repeatable planar accuracy. This unit balances aggressive heavy stock removal for rough grinding and controlled semi-finishing capabilities, all within a single machine footprint. It eliminates the need to move parts between separate rough and finish grinders, streamlining floor workflows and slashing overall operational costs for heavy manufacturing facilities.
Despite its focus on industrial throughput, the grinder maintains reliable surface finishing control, making it ideal for mid-to-high tolerance structural components where uniform flat mating surfaces are critical.
Standard Machining Accuracy Ratings
All tolerance readings below are recorded under continuous full-load operating conditions; final results will shift slightly based on workpiece material and dimensions:
- Parallelism deviation: 0.01 mm
- Flatness tolerance: 0.01 mm
- Cross-batch thickness variation: 0.02 mm
- Achievable surface roughness: Ra 0.8 μm
These consistent tolerance bands deliver perfectly uniform contact surfaces for heavy-duty bearing races, industrial flanges, construction machinery discs and other load-bearing circular parts. Reliable planar finishing directly extends the service life of assembled equipment by eliminating uneven pressure points during operation.
Full Technical Specs and Built-In Performance Advantages
Reinforced Spindle & Adjustable Grinding Head Travel
A robust Φ150mm main spindle shaft resists bending under deep cutting loads - a common flaw in smaller grinders tasked with thick metal workpieces. The grinding head offers 130mm of vertical travel, creating ample setup room for custom fixtures and parts with varying thickness profiles.
Its industry-leading 0.001mm minimum feed increment enables ultra-precise depth control during semi-finishing passes. Operators can dial back material removal rates for refined surface results without switching machines, condensing two-stage grinding workflows onto one unit.
Independent Multi-Motor Power Distribution
Three separate drive systems split power delivery to isolate vibration and prevent single-component burnout during nonstop production:
- Twin 30kW spindle motors: Deliver sustained high torque for fast stock removal on large, thick circular blanks, with zero risk of stalling under full cutting loads
- Dual 1.8kW feed motors: Drive smooth, steady linear movement for the grinding head, ensuring identical cutting depth across every workpiece in a run
- Single 0.9kW wheel dressing motor: Powers consistent, repeatable abrasive wheel truing to maintain sharp cutting edges and stable long-run accuracy
The machine's total installed power reaches 96kW, a clear indicator of its heavy-industry design. It is purpose-built for high-output factory production lines, not low-volume lab or prototype work.
Oversized Vibration-Dampening Frame
With overall dimensions of 7000 × 5000 × 2400 mm (L × W × H), this extra-large base evenly distributes the unit's weight and suppresses vibration far better than compact, lightweight frames. Vibration bleed directly ruins flatness consistency during multi-hour shifts; this reinforced build eliminates that issue entirely. The rigid construction also reduces wear on core spindle and feed assemblies, lowering long-term maintenance frequency and downtime.
Industrial Applications
This heavy-duty planar grinder is widely deployed at large bearing foundries, construction machinery component plants, heavy-duty truck parts manufacturers and general heavy metal fabrication facilities. It specializes in high-volume surface grinding for thick, large-diameter circular metal blanks, raising finished part pass rates and shortening end-to-end component processing lead times.
Frequently Asked Questions
Q1: What production environments is the SX150-12YL best suited for?
A: It is designed specifically for mass production of large, thick circular workpieces within heavy manufacturing verticals like bearing production and construction machinery component machining. It fully supports 24-hour uninterrupted grinding lines.
Q2: What production benefits does the 0.001mm micro-feed provide?
A: The ultra-fine feed adjustment lets operators complete precision semi-finishing passes on the same machine used for rough grinding. This removes extra handling steps and eliminates the cost of a dedicated secondary finishing grinder.
Q3: Why use multiple independent drive motors instead of one single power unit?
A: Separating spindle, feed and wheel dressing power sources contains vibration and distributes cutting load evenly. This design avoids motor overload during heavy grinding cycles, stabilizes machining accuracy, and cuts premature wear on individual drive components for a longer machine service life.
