Abstract
A special machining tool is characterized in that the tool comprises a tool handle, a tool bar and a tool bit and is installed on numerical control machine tools. The tool adopts the BT50 tool handle system and the tool bit adopts the high-performance cutting material W6Mo5Cr4V2, thus the tool can machine the key grooves into finished products with twice operation. The tool has extremely high machining efficiency and precision.
Description
Technical field the present invention relates to mechanical manufacturing field, relates to a kind of mechanically special machining tool concretely.
Background technology adopt rational cutter structure and select for use suitable high-efficiency and precision cutter can improve greatly machine-building productivity ratio, improve the quality of products, reduce production costs, greatly machine building industry influence.We find to be difficult to guarantee with universal cutter the depth of parallelism requirement of its center keyway 0.025mm when making 870,000 KW and above high power turbine generator bearing case with the Toshiba Corp cooperation.We have got in touch that now each does the well-known manufacturer of cutter: SANDVIK, Mitsubishi, Sumitomo, Toshiba, Dai Jie, Hitachi, KYOCERA greatly in the world, all none is used for processing the dedicated tool of this keyway for KENNAMETAL, ISCAR for this reason, therefore early stage can only be with the mode of artificial reconditioning, need in this way to spend the plenty of time, and the reconditioning surface accuracy is not fine.For this reason we required precision has designed a kind of dedicated tool according to keyway specially.Can be with dedicated tool once with the keyway completion of processing, and the depth of parallelism satisfies the 0.025mm requirement.
Summary of the invention the purpose of this invention is to provide a kind of cutting tool special for processing that can process high power turbine generator bearing case symmetrical centre keyway.
The object of the present invention is achieved like this: according to the width of keyway own
We determine that the width of cutter is
So only need two cuttves just can be with the keyway processed finished products.
Cutter adopts BT50 handle of a knife system, can be directly installed on the Digit Control Machine Tool; The cutter material is selected W6Mo5Cr4V2 for use, to improve cutting ability.
A kind of process tool of processing large steam turbine generator bearing case center keyway, this cutter are specially adapted to the keyway that symmetry processing both sides have very high degree of precision to require.Can be with this cutter with both sides keyway time processing finished product, and avoided the inefficiency and the reconditioning surface accuracy deficiency of artificial reconditioning, belong to the machining specialized tool.
The present invention has broken through existing traditional thinking and structure, with one disposable with the keyway processed finished products dedicated tool, and satisfies the high required precision of keyway itself, shorten process time, working (machining) efficiency is high, and working (machining) efficiency has improved 300%, has reduced human cost and manufacturing cost.

The specific embodiment is in Fig. 1 and the described cutting tool special for processing structural representation of Fig. 2 sketch, and cutting tool special for processing is made up of handle of a knife 1, knife bar 2 and cutter head 3; Cutter adopts BT50 handle of a knife 1 system, is directly installed on the Digit Control Machine Tool; Cutter head 3 adopts high-performance cutting material W6Mo5Cr4V2, and only need two cuttves can be with the keyway processed finished products with this cutter like this, and working (machining) efficiency and precision are high.According to the width of keyway own
We determine that the width of cutter is
So only need two cuttves just can be with the keyway processed finished products.
Cutter adopts BT50 handle of a knife system, can be directly installed on the Digit Control Machine Tool; The cutter material is selected W6Mo5Cr4V2 for use, to improve cutting ability.
The present invention has broken through existing traditional thinking and structure, with one dedicated tool has been solved the difficult problem in the process, and shortens process time, and working (machining) efficiency is high, and working (machining) efficiency has improved 300%, has reduced human cost and manufacturing cost.
Claims (2)
1. mechanically special machining tool is characterized in that: form cutter by handle of a knife, knife bar and cutter head; Cutter is installed on the Digit Control Machine Tool.
2. mechanically special machining tool according to claim 1 is characterized in that: cutter head adopts high-performance cutting material W6Mo5Cr4V2, and only need two cuttves can be with the keyway processed finished products with this cutter like this, and working (machining) efficiency and precision are high.According to the width 114.3 of keyway own
0 + 0.13, we determine that the width of cutter is 65
-0.1 0, so only need two cuttves just can be with the keyway processed finished products.
