Gantry Type Surface Grinding Machine MCW5316A×35

Key Advantages of the MCW5316A×35 Portal Grinding Machine

• Rigidity and Vibration Resistance of the Structure
  The machine features a portal-type layout with a closed structure made of high-quality cast iron. The wide cross-section of the crossrail, the large distance between the guideways, and the minimal distance from the spindle axis to the Z-axis guideways ensure maximum stability during heavy-duty grinding.

• Advanced Technology
  Both grinding heads (horizontal and vertical) are equipped with combined hydrostatic and hydrodynamic plain bearings. This guarantees the highest rotational accuracy, complete elimination of mechanical wear, long service life, low starting power, and excellent vibration resistance—all of which are critical for grinding precision guideways.

• Intelligent Lubrication System
  The spindle lubrication system is equipped with an independent hydraulic unit featuring a hydraulic accumulator. In the event of a pressure drop or oil shortage, the system immediately triggers an alarm and stops the spindle, while the accumulator provides an emergency oil supply to prevent bearing damage. Additionally, the system continuously monitors oil temperature to maintain machining accuracy.

• High-Precision Motion Kinematics
  The Y, V, Z, and W axes are driven by high-performance servo motors via precision ball screws. The transmissions are pre-tensioned and utilize a "fixed screw, rotating nut" design, which minimizes axial runout. Heavy-duty roller linear guideways with multiple carriages are used to ensure maximum smoothness of travel.

• Automated and Precise Table Control
  The longitudinal movement of the table (X-axis) is actuated by a double-rod hydraulic cylinder. The table position is tracked by a high-precision encoder, allowing the system to automatically and highly accurately reverse the table at preset distances, thereby eliminating manual adjustment errors.

• Reliable Diagnostic and Safety System
  The control system, based on a Siemens Programmable Logic Controller (PLC) and a touch panel, continuously monitors the machine's condition. Upon detecting insufficient lubrication, clogged oil lines, or a pressure drop, the machine automatically stops and displays a clear error message, preventing catastrophic failures.

• Efficient Coolant Supply and Filtration System
  The coolant supply system is equipped with a high-pressure pump, a magnetic separator, and a baffle system in the tank. This ensures the thorough filtration of the coolant from abrasive particles and maintains a stable temperature regime in the cutting zone, which directly impacts the surface finish (Ra < 0.63 μm) and the geometric accuracy of the workpiece.
