The working principle of the cylindrical grinder tool magazine: pre-install the turning tool on the tool holder, and then press the tool holder on the radial position of the tool holder frame in turn. When the tool needs to be changed, the CNC system issues a command to drive the servo motor , The anti-backlash gear drives the large gear ring to rotate the corresponding angle, so that the corresponding tool rotates to the tool change position. At this time, the vertical tool post enters the tool change position, removes the tool holder, and returns to the cnc machining parts position to continue processing the next process. In general, the rotating movement of the grinding wheel of the cylindrical grinder does not require speed adjustment, and it can be driven by a three-phase asynchronous motor, and only one-way rotation is required. When the capacity is large, it can be started by Y-triangular depressurization. In order to ensure its processing accuracy, make it run smoothly, and ensure that the inertia of the worktable is small and no impact when the reciprocating movement of the worktable is reversed, hydraulic transmission is adopted to realize the reciprocating movement of the worktable and the grinding wheel. The box feeds horizontally.

Basic requirements for the use of cylindrical grinder equipment:

• 1. Numerical control equipment requires to avoid places with dampness, excessive dust and corrosive gas;
• 2. Avoid direct sunlight and other heat radiation, and keep precision numerical control equipment away from equipment with large vibrations, such as punches, forging equipment, etc.;
• 3. The operating temperature of the equipment should be controlled between 15 degrees and 35 degrees. The precision processing temperature should be controlled at about 20 degrees, and the temperature fluctuation should be strictly controlled;
• 4. In order to avoid the influence of large power fluctuations (greater than plus or minus 10) and possible instantaneous interference signals, the numerical control equipment generally adopts dedicated power supply (for example, it is separated from the low-voltage power distribution room for use by the cylindrical grinder), and a voltage stabilizing device is added And so on, can reduce the impact of power supply quality and electrical interference.

The appearance of the linear motor makes the servo motor + rolling screw drive device very embarrassing, because the linear motor can replace the servo motor + rolling screw to drive the linear three-axis. Introduction to cylindrical grinders Linear motors are generally used on cylindrical grinders. Generally, cylindrical grinders rarely use linear motors to drive linear three-axis, because the current linear motor-driven three-axis technology is still mature enough. Next, let the cylindrical grinder introduce the advantages and disadvantages of linear motor driven linear three-axis. Linear motors drive linear three-axis has the advantages of fast speed, high efficiency and rigidity. Cylindrical grinder introduction The speed of linear three-axis driven by linear motor is 2-3 times faster than the speed of servo motor + rolling screw driving linear three-axis. The feed speed of servo motor + rolling screw driving linear three-axis is generally 48m/min , And the linear motor drives the linear three-axis feed speed at 86m/min; because the servo motor + rolling screw is the transmission form, the rigidity is not as good as the linear motor.
