Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] refer to Figure 1 to Figure 5 , the present embodiment adopts the following technical scheme: improved gasket groove processing technology, which includes the following process steps: 1, rough milling: rough milling adopts a customized four-tooth cutter, and guarantees that the parts reserve 0.1-0.2mm margin during processing, Fast feed, large cuts (reduced machining time).

[0020] 2. Fine milling: The original single-tooth machining tool is used for fine milling, and the cutting-resistant PCBN cubic boron nitride blade is replaced.

[0021] The contrast of processing parameter of this specific embodiment:

[0022]

[0023] From the data analysis, it can be seen that the improved plan adopts the method of combining rough and fine mil...

Abstract

The invention discloses an improved machining process for gasket grooves and relates to the technical field of improvement of tools in sealing groove machining. The improved machining process includes the following process steps that 1, rough milling is conducted, a customized special tool with four teeth is adopted for rough milling, the effect that allowance of 0.1-0.2 mm is reserved for parts in machining is guaranteed, feed is quick, and cutting amount is large; and 2, finish milling is conducted, an original machining tool with one tooth is adopted for finish milling, and a blade of the original machining tool is replaced by a cutting-resistant blade, namely a polycrystalline cubic boron nitride (PCBN) blade. According to the improved scheme, the method that rough milling and finish milling are combined is adopted, and the customized homemade machining tool with the four teeth is adopted for rough milling, so that roughing feed and fly cutting are achieved; the cutting-resistant PCBN blade is adopted for finish milling on the basis of the original machining tool, so that cutting speed of the tool is increased.

Description

technical field [0001] The invention relates to the technical field of tool improvement in sealing groove processing, in particular to an improved gasket groove processing technology. Background technique [0002] Wellhead devices and Christmas tree equipment are mainly used in drilling and oil production equipment in the oil and gas industry. In order to prevent leakage when multiple parts are connected, RX and BX gasket rings are required, and the gasket rings are installed on the corresponding gaskets. slot, so its processing requirements are very high. The traditional processing method of machining the gasket groove is the ordinary V-shaped blade for rotary milling. The processing time of the ordinary V-shaped blade is very short. After processing four grooves, the blade needs to be replaced. After replacing the blade The adjustment of the middle diameter of the tank is inconvenient, the adjustment time is long, and the production efficiency is low. [0003] To sum up, ...
