CNC-controlled three-axis parallel roll collar hole pattern machining method

Abstract

The invention discloses a CNC-controlled three-axis parallel roll collar hole pattern machining method. A roll collar to be machined and a diamond grinding wheel with the standard radius are installedon a grinding machine, a grinding program is edited according to a hole pattern to be machined, parameters are input, a machining stroke is generated through CNC, and the diamond grinding wheel grinds the roll collar according to the machining stroke. The grinding steps comprise coarse grinding, pre-fine grinding, fine grinding and smoothing, after grinding, a WENTAST full-automatic measuring system is used for measuring parameters such as the groove distance and the groove depth of the roll collar, and the next grinding step is selected according to the measuring result until the hole pattern meets the requirement. According to the method, the diamond grinding wheel with the standard radius can be adopted for grinding different hole patterns, the diamond grinding wheel does not need to be specially customized and formed for grinding the roll collar with the optimized hole pattern, the special-shaped hole pattern which cannot be machined by the formed grinding wheel can be ground, on-schedule production of wires with the non-common specification can be guaranteed, the stock of the formed diamond grinding wheel is reduced, the production cost is reduced, and technical support is provided for wire production.

Description

technical field [0001] The invention relates to a roller ring pass processing method, in particular to a CNC-controlled three-axis parallel roller ring pass processing method. Background technique [0002] There are hundreds of passes in the finishing mill and reducing and sizing mill in the wire rod factory. The pass of the carbide roll ring is generally processed by grinding with a diamond shaped grinding wheel on a special roll ring grinder. Each roll ring pass It needs to be ground with a shaped diamond grinding wheel corresponding to the pass type. With this grinding method to process the pass type, the wire factory usually needs to use one for the other, so the inventory of the formed diamond grinding wheel needs to be at least twice the number of pass types, and the inventory is large. , The inventory management of formed diamond grinding wheels also consumes a lot of manpower, especially for more than 20 kinds of infrequently used pass types such as finishing mills a...

[0002] There are hundreds of passes in the finishing mill and reducing and sizing mill in the wire rod factory. The pass of the carbide roll ring is generally processed by grinding with a diamond shaped grinding wheel on a special roll ring grinder. Each roll ring pass It needs to be ground with a shaped diamond grinding wheel corresponding to the pass type. With this grinding method to process the pass type, the wire factory usually needs to use one for the other, so the inventory of the formed diamond grinding wheel needs to be at least twice the number of pass types, and the inventory is large. , The inventory management of formed diamond grinding wheels also consumes a lot of manpower, especially for more than 20 kinds of infrequently used pass types such as finishing mills and reducing sizing roll rings. Spare diamond forming grinding wheel. After receiving the order for wire rods with special specifications, it is necessary to customize the forming diamond grinding wheel. The custom cycle is long, which affects the delivery of the wire rod order contract. For M1R type special-shaped pass and carbide roller rings that require chamfering, it cannot be used.
