8) to sliver and vane body blast;
9) according to drawing welding blade and sliver, ensure that cylindrical stays mill 0.7-0.8mm;
10) blast is carried out to cutter head, process of turning blue;
11) grinding center hole and trapezoidal thread;
12) grind off the unnecessary welding slag of blade and sliver place, and roughly grind cutting cone; Corase grind alloy blade relief angle stays 0.5-0.7mm surplus;
13) corase grind alloy blade cylindrical and sliver cylindrical stay mill amount 0.25-0.35mm; Further corase grind alloy blade relief angle stays 0.2mm surplus;
14) thick fine grinding alloy blade everywhere anterior angle to size;
15) adopt and align the method that reamer afterbody centre bore positions, make limited block be arranged on localization method between two adjacent alloy blades, then the cylindrical of outer mill Ф 19mmh6 and trapezoidal thread cylindrical are to figure paper size;
16) finish turning trapezoidal thread is to size;
17) refine alloy blade blade cylindrical and guide block cylindrical, reserve 0.1mm allowance;
18) fine grinding alloy blade blade cylindrical and inverted cone degree are to size further, and mill guide block cylindrical is to dimensional requirement;
19) refine alloy blade everywhere after angle sections relief angle to dimensional requirement;
20) grind cutting cone intersection point with oilstone and become R0.2-0.3mm.
This deep-hole alloy reamer adopts above-mentioned step successfully to achieve cutter one end to have alloy blade, and the other end has the procedure of processing of trapezoidal thread; Make use of the step of first milling sloping platform at rat holing, ensure that the dimensional accuracy of inclined hole; Each angle of alloy blade carries out corase grind repeatedly simultaneously, then the step of refining, and ensures the dimensional accuracy of alloy blade; This deep-hole alloy reamer adopts above-mentioned steps to not only increase production efficiency, greatly reduces the appearance of waste product, and shortens the cycle of production, improve the economic benefit of company.
