【How to detect the inclination error when the chute moves?】

Answer: When the chute moves, the inclination error is detected. Place the level on the dovetail guide rail of the chute close to the tool rest and perpendicular to the guide rail of the bed (i.e. the travel direction of the chute). Move the chute, record the reading every 250mm (or 500mm, or less than this value), and detect it on the whole travel of the chute. The maximum algebraic difference between the readings of the level on the 1000mm stroke and the whole stroke is the inclination error. The inclination error is expressed in terms of slope or angle.

【How should the tilt error be detected when the worktable moves?】

Answer: For the detection of inclination error when workbenches such as cylindrical grinder, thread grinder, broach grinder, gantry planer and gantry milling machine move, a level should be placed in the center of the worktable and perpendicular to the moving direction of the worktable (if the grinder is inclined, the level should be placed on a special pad). Move the worktable, record the readings every 250mm (or 500mm, or less than this value), and record at least three readings for the short bed on the whole stroke of the worktable. The maximum algebraic difference between the readings of the level on the 1000mm stroke and all the strokes is the tilt error when the worktable moves.

【How to detect the inclination error when the beam moves?】

Answer: To detect the inclination error when the beam moves, a level is placed parallel to the beam at the center of the beam guide rail. Move the beam, record the readings every 500mm (or less than 500mm), and record at least 3 readings on the whole travel of the beam. When testing on the whole stroke of the beam, the two vertical tool holders (or milling heads) shall be moved to the symmetrical position on the beam. The moving direction of the beam can only be from bottom to top, not back and forth. This method is usually used to detect the inclination error of the beam when it moves, such as
