Do you know how to choose shoe factory's grinding machine?

1. Quiet Operation: Dual Control from Structure to Parameters

Noise control is a core indicator of equipment user-friendliness. High-quality models achieve quiet operation through three design aspects:

Motor and Fan Optimization: Prioritize brushless EC-TEC motors (e.g., Festool ETS EC 150), combined with large-diameter, low-speed fans (only 1400 rpm at an airspeed of 11 m/s), which can reduce noise to 68-70 dB—equivalent to the volume of normal conversation.

Shock Absorption Structure: A metal frame plus anti-vibration base can reduce vibration transmission. For better stability, it is recommended to choose household models weighing over 8 kg or industrial models over 60 kg.

Parameter Pitfalls to Avoid: Look for the label "noise ≤ 75 dB" and avoid models with a fan power < 1.1 kW, as such equipment often relies on high-frequency noise to gain suction.

2. Grinding Wheel Spindle Stability: Runout Determines Grinding Precision

Grinding wheel spindle runout directly affects the flatness of shoe soles. Key points to focus on when purchasing:

Core Configuration: Prioritize spindle bearings from brands like SKT and NSK. A double-bearing structure can control radial runout within 0.02-0.05 mm, avoiding grinding marks or dimensional deviations.

Balancing Technology: Industrial-grade models should be equipped with a dynamic balancing system, and a residual unbalance of G2.5 class is preferred. For household models, manual testing is feasible—when idling, use a dial indicator to check; a pointer fluctuation ≤ 0.01 mm is considered qualified.

Practical Inspection: After starting the machine, observe the operation of the grinding wheel. Models with no obvious vibration, no resonance of the machine body, and stable operation for 1 consecutive hour are more reliable.

3. Dust Suction Effect: Collaborative Design of Air Duct and Filtration

Efficient dust suction requires a closed loop of "suction power - filtration - collection":

Suction Parameters: A fan power ≥ 1.1 kW and an airspeed ≥ 11 m/s can capture grinding dust instantly.

Filtration System: Prioritize washable filters (e.g., OB-F720 model), combined with an independent dust suction hood and multi-stage air duct to prevent dust leakage.

Structural Details: Models with a cleaning roller installed behind the sanding frame and a dust suction port on the conveyor belt (e.g., special sanders for rubber sheets) can reduce secondary dust emission.
