Servo Upside down Special Machine When machining parts, cutting the workpiece is an indispensable process, and grooving on the workpiece is also common. The efficiency of cutting and grooving is inseparable from the rigidity of the machine tool. The rigidity of the spindle of the machine tool and the rigidity of the tool tower are the main reasons that affect the vibration of the workpiece. The cutting method in cutting and grooving is also critical.

Let's split the cutting method to see how to improve the efficiency of cutting and grooving workpiece processing.

1, Servo Upside down Special Machine Cutting: the common method of car grooving. The common methods of grooving on the workpiece surface are the outside grooving, the inside grooving and the end grooving. The choice of groove cutter. Generally use high-speed steel groove tool groove.

2, the groove method, the turning accuracy is not high and the width of the narrow rectangular groove, you can use the knife width equal to the width of the groove groove knife, using the direct entry method once out.

3. Rectangular grooves with higher turning accuracy are generally divided into two turns. Turning wide grooves can be cut by multiple direct drive method, and leave a certain finishing margin on both sides of the grooves, and then fine turning to size according to the depth and width of the grooves.

4, turning smaller circular grooves, generally with forming tool turning; Turning large circular grooves can be turned with both hands and checked and trimmed with a template. Turning smaller trapezoidal slots is generally completed with forming tools; Turning the larger trapezoidal groove is usually done by turning the straight groove first, and then using the trapezoidal knife straight into the method or the left and right cutting method.

5, rectangular slot inspection and measurement. Grooves with low accuracy requirements are generally measured with steel straightedge and calipers. The grooves with higher accuracy requirements can be checked and measured with micrometers, templates, plug gauges and vernier calipers.

6, cut off to use a cutting knife, the shape of the cutting knife is similar to the car slot knife, but because of the narrow head and spoon, it is easy to break. Cutting knife has high-speed steel cutting knife, carbide cutting knife, elastic cutting knife, reverse cutting knife and other types.

7, reasonably increase the feed speed, but to ensure that it does not cause excessive vibration and tool wear under the premise of ensuring the processing quality. According to the workpiece material and cutting conditions, the test cutting experiment is carried out to find the appropriate feed speed range to improve the processing efficiency.

8, by optimizing cutting parameters, such as cutting speed, feed rate, cutting depth, coolant use, etc., to improve processing efficiency. Reasonable selection of the combination of cutting speed and feed rate can achieve good machining results.

9, in the program writing, as far as possible to reduce the empty walking time, that is, to reduce the machine tool on the processing path of the non-cutting movement time. Optimize the cutting path and tool trajectory, so that the moving distance of the tool in the machining process is shorter, reduce the idle travel time, and improve the processing efficiency.
