Gantry surface grinder It is capable of performing mirror finishing and grinding, making it particularly well suited for precision machining in industries such as mold making, cutting tools, connector terminals, and semiconductors. Moreover, CNC‑controlled machines can simultaneously achieve high machining accuracy while processing curved surfaces—including cylindrical, external‑cylindrical, and arcuate forms—thereby enabling multifunctional capabilities comparable to those of gantry surface grinders.

　　A gantry-type surface grinder is also referred to as a surface grinding machine. Although it is relatively easy to operate, it can handle a wide variety of workpiece types and typically requires numerous fixtures to complete each operation. It delivers very high precision; when equipped with digital readout, accuracy can be maintained within ±0.001 mm. The machine is capable of machining flat surfaces, right angles, inclined planes, slots, circular arcs, step differences, and more. These operations can also be combined—for example, machining inclined slots, stepped inclined surfaces, or inclined circular arcs—as long as the features are continuous and through‑going. It offers high processing efficiency, excellent precision, and relatively low production costs.

　　The outstanding advantages of machining on a gantry surface grinder include:

　　1. High precision and stable quality of machined parts

　　 Gantry surface grinder It boasts both high positioning accuracy and excellent repeat positioning accuracy, making it relatively easy to ensure dimensional consistency across a batch of parts. Provided that the process design and program are properly formulated and carefully executed, the parts can achieve high machining precision, while also facilitating quality control throughout the manufacturing process.

　　II. High degree of automation, which can reduce the physical workload of operators.

　　The machining process on a gantry surface grinder is carried out automatically according to the input program; the operator need only perform initial tool setting, load and unload workpieces on the EDM machine, and change tools. During operation, the primary tasks are observing and monitoring the machine’s performance.

　　3. Dimensioning shall conform to the characteristics of grinding‑machine machining.

　　 Gantry surface grinder In CNC programming, the dimensions and positions of all points, lines, and surfaces are referenced to the program origin. Therefore, part drawings should directly specify coordinate dimensions, or, whenever possible, dimension annotations should be based on a common datum.

　　The control oil then actuates the main valve to change its direction. When the pilot valve remains in its initial position, replacing the solenoid directional valve with an electro‑hydraulic directional valve establishes a new method of directional control. The electro‑hydraulic directional valve comprises a pilot‑valve solenoid spool and a main‑valve hydraulic spool. In this system, the pilot valve switches the control oil circuit to effect the directional change. Since the flow direction of the control oil remains unchanged, the directional valve stays at its original position, the main oil circuit retains its original flow path, and the worktable can continue to advance without interruption.

　　 Gantry surface grinder It is compatible with the ideal control curve. The gantry-type surface grinder employs a hydraulic‑drive reversing system featuring electro‑hydraulic proportional valves, enabling smooth, impact‑free direction changes by actively reducing flow to lower speed. This intelligent, adaptive reversing system ensures optimal performance even under varying operating conditions. By providing precise, intelligent control over output displacement and velocity, it confers a high degree of controllability to the reversing process, thereby supporting an exceptionally broad range of applications.
