NC machining tool and workpiece clamping [Dec 01,2016]
NC machining tool and workpiece clamping
CNC machining in the clamping tool, need to handle, arbor, card sets, and other parts of Latin clean, then put the tool to install ATC knife or knife tower adjacent to the attention of the cutter diameter or length of the existence of interference, the input tool compensation is the correct value, and ensure the installation position and the requirements of the program the same position. Cutting tool installation, in order to meet the processing requirements to reduce the length of the knife, the knife side of the suspension, the general control in diameter (height) of the (1.5-3) times. Face contour turning, turning, turning point and forming need to ensure that the workpiece rotary center high, artificially adjusted as necessary. End milling cutter, milling cutter, reamer cutter after installation, need to check the radial runout and end beat (through observation tool runout), artificial adjustment according to the actual processing situation. CNC machining is a precise and rigorous processing method, so the tool of the card and adjustment must be carefully completed.

CNC machining should be strictly in accordance with the provisions of the positioning of the workpiece, as far as possible to make the positioning reference and design basis, the processing surface as far as possible using the same positioning reference. Rough machining and positioning of the benchmark should be given priority to choose not to process or processing margin relatively small flat surface, and can only use once, precision machining positioning reference is processed surface. Installation fixture in the machine table, we must first wipe the datum, and according to the requirements of alignment, fixed. Before clamping the workpiece, the positioning surface, the clamping surface, the iron and the clamp can be positioned, and the clamp surface can be cleaned without burr. After the tool and the work piece is completed, the card is carefully checked again. After that, the machining operation is confirmed.
