Mid-sized manufacturing plants that produce multiple types of circular mechanical parts often run into a universal headache: standard fixed-spec grinders cannot flexibly match changing workpiece sizes, forcing frequent fixture rework and slowing down overall output. Many generic grinding models lock users into rigid feed speed gears, creating uneven surface texture when shifting between rough stock removal and light finishing work.
The LGM50Y power surface grinder addresses these common production constraints. Its core machining dimensions can be modified at the factory stage to match unique part specifications. The feed system delivers seamless speed transitions without discrete gear steps. Dual synchronized drive motors supply uniform cutting force for both stock reduction and light finishing cycles. Its 5-ton cast construction delivers reliable vibration suppression within a compact footprint.
This model avoids the narrow application range of ultra-precision small-part grinders and heavy-duty large-blank grinders. It serves facilities with daily batch changeovers, with fully configurable sizing parameters built to align with site-specific production workflows.
Machining Accuracy
All tolerance data below is collected under non-stop full-load grinding cycles; minor deviations may appear based on workpiece material hardness and geometry:
- Parallelism deviation: 0.01 mm
- Flatness tolerance: 0.01 mm
- Cross-batch thickness variation: 0.015 mm
- Achievable surface roughness: Ra 0.8 μm
This accuracy range fits mainstream mechanical components such as standard bearing rings, pump sealing discs and small equipment flanges. Uniform flat surfaces avoid uneven load distribution after assembly, cutting premature wear and extending the service life of finished mechanical assemblies.
Features and Advantages
Customizable Machining Range and Standard Abrasive Wheel Setup
A defining feature of this unit is its adjustable working range. Baseline factory dimensions cover mainstream medium circular blanks:
- Workpiece length span: 10-200 mm
- Processable blank thickness: 2-40 mm
The machine is fitted with a 500 mm diameter abrasive wheel. The calibrated contact surface balances stock removal efficiency and uniform surface texture for medium-thickness metal stock. Operators eliminate over-grinding defects common on grinders equipped with oversized abrasive wheels for thin, compact workpieces.
The grinding head provides 120 mm vertical travel. Sufficient vertical clearance enables rapid fixture replacement, minimizing downtime between separate production batches.
Smooth Variable Motion System and Calibrated Spindle
All motion axes adopt workshop-focused speed calibration for consistent daily operation:
1. Fixed spindle rotation speed at 1060 RPM: Tuned for carbon steel and alloy steel blanks, creating even grinding textures across the entire workpiece surface
2. Continuous-range feed movement from 2.7 to 13.4 m/min: No segmented speed gears. Staff can dial up or down material removal speed gradually, preventing the uneven surface marks caused by sudden speed jumps on gear-controlled grinders
3. Adjustable wheel dresser travel speed (0.5-1.5 m/min): Supports controlled wheel truing to keep abrasive edges sharp, maintaining steady dimensional accuracy through long production shifts
Twin Motor Drive and Space-Saving Rigid Body
Two 15kW grinding head motors operate in synchronized tandem to output balanced cutting torque. The dual-drive structure distributes operational vibration evenly across the cast base, preventing unilateral spindle deflection that compromises flatness consistency during multi-hour continuous runs.
Total machine weight reaches 5000 kg, with overall outer dimensions measured at 2400 × 2200 × 1600 mm. The compact rigid frame requires no specialized reinforced concrete foundation for installation on standard factory flooring, cutting project setup costs and lead times. The condensed outer profile allows direct integration into existing multi-process production lines or standalone finishing work cells.
Industrial Use Cases
This flexible planar grinding equipment is deployed at general bearing manufacturers, standard machinery component workshops, pump and valve component producers, and medium-scale precision metal fabrication job shops. It specializes in mixed-batch surface finishing for medium-diameter circular metal blanks, cutting batch changeover duration and lifting overall production efficiency for facilities handling multiple component variants.
Frequently Asked Questions
Q1: What benefits come with customizable dimensional parameters?
A: Core working dimensions including maximum workpiece length and thickness can be reconfigured during manufacturing to match your unique part sizes. You won't have to compromise your production flow to adapt to a one-size-fits-all standard grinder.
Q2: How does continuous-range feed movement outperform gear-fixed feed systems?
A: Operators can tweak material removal speed smoothly without hard gear shifts. This delivers more consistent surface finish and reduces scrap rates when switching between rough grinding and semi-finishing tasks.
