The workpiece material is Q345D, is the whole hard alloy reamer diameter 18 6 blade laevorotatory right edge reamer, now found out the hole hinge inside there is always a circle cut, when processing the machining allowance for unilateral 0.2mm, reamer speed 120r/s, feed rate is 45mm/min, the cooling liquid is emulsion, which can master under the guidance, the argument is correct. It's better to give a machining parameter, s and F, thank you. The tool is added to several beds, beating about 1 wires.
Do you use G81 or G85 or G01 feed?
Spindle runout of less than 0.003, the diameter of the cutter size, internal cooling. Excuse me, where is the reason?.
The tool flank surface is not smooth enough, the inverted cone angle is not correct, and the cooling is not enough.
I need to use this knife to do the work. The material is QT450-10. When the tool is made, the first step is to process and reheat the required hardness without welding the blade, then weld the blade and reprocess.
You should use the 40Cr to do the carrier, alloy blades. Actually come up with these heat treatments to sweat! How 40CR heat treatment can do directly tools?If you do the words, and it. Hardness is based on the condition of your knife, and 32-38HRC shouldn't be a big problem
What drill and reamer are used to process an empty diameter of 8mmH7?
You can refer to the relevant mechanical processing manual, should have an introduction, I think it should be 7.8 of the drill, 8 of the reamer
Why are the dimensions of the reamer larger than the size of the hole?
The reamer is fine cutting tools a certain size of the hole, the hole in finishing before must leave the finishing allowance, so the hole than the knife which small dumplings,What this says is positive solution. What you ask is very mechanical.
If you want to drill out 20 of the hole with a reamer, what size drill should you use first?
The reamer used for machining is of good quality and it is recommended that the drilled hole be 19.9. Usually, the allowance for the reamer is 0.1-0.2mm. As to how large the drill is, it depends on how large the hole you drill out of. You can try using the 19.5 bit. A rotary tool with one or more cutter teeth for removing thin metal on the surface of a machined hole; a rotary finishing tool having a straight or spiral blade; used for reaming or trimming.A rotary tool with one or more cutter teeth for removing thin metal on the surface of a machined hole; a rotary finishing tool having a straight or spiral blade; used for reaming or trimming. The structure of the reamer is mostly composed of the working part and the shank part. The main part of the work is cutting and calibration functions, the calibration Department has inverted taper diameter. The shank is used for clamping by the clamp and has a straight handle and a taper handle.
In mechanical engineering materials, what are the materials of the reamer?
There are white steel reamer, carbide knife, as well as surface coating. The reamer also breaks the moving reamer and the machine reamer.
What a few general tolerances reamer level holes to machining, such as phi 10H7, the high precision hole boring
1. mechanical processing, general IT7 and IT8 reaming can be used as the end of the process.2. the boring can eliminate the machining deviation of the front process to a certain extent.The 3. reamer is a sizing tool, and the final bore diameter is mainly determined by the cutter.4. cutter diameter is adjustable, adjustable aperture is by the skills of staff to ensure the.5. reamer is a multi edge cutter, it has higher machining stability, higher work efficiency, easier to obtain good surface effect of workpiece.6. do not take measures, larger hole boring cutter to shock.7. boring is not suitable for the processing of smaller diameter holes.
