Q: What's the difference between the reamer and the milling cutter? They all look the same: Depends on what you use, the milling cutter is broken, you can grind the reamer can not,

Q: Diameter 4.2, depth 12, roughness 0.8, tolerance 0.02., cutting, each edge 0.02. material is stainless steel. Carbide reamers are used, with a 45 degree reamer at the beginning and a crack at the tip! Then change to 30 degrees, the middle of the place or collapse! Either the size is too bad! In the gloom!: 1, use the oil hinge, do not use cutting fluid. 2, down feed, slow down, to be uniform, rhythmic, it is best to play automatic. 3, can not be intermittent, speed slow, 4, reamer material to see if you can change the soft point, as long as the processing can move like.

Q: In the lathe, with a floating reamer machining material for cast iron, diameter of 55mm hole, leaving margin 0.1mm, lathe speed is appropriate!!: Reaming is actually the lower the speed, the better, but to balance with efficiency. So, according to the actual choice of 30-120

Q: What a few general tolerances reamer level holes to machining, such as phi 10H7, the high precision hole boring: General machine reamer is only guaranteed diameter tolerances, boring can ensure the cylindricity and position tolerance. 10H7 is generally used as a positioning pin hole hole, usually has the position degree, then recommend the use of CNC machine milling cutter.

Q: Hit a circle, beating is 2-3 wire, reaming 16 holes should be little problem. 20-30 spare margins are left, and the reamer is new. But why does this problem arise? Ask the teacher for help!!!: With the stone cutter head repairing

Q: The sale of these spiral reamer (punch) is illegal? Crime?12 blade spiral reamer, right helix 2-3 degreesFront diameter 5.45 to 5.5 mm, rear diameter 5.40 to 5.5 mm, middle diameter 5.75 mm, line depth 0.1mm or so: The sale of these spiral reamer (punch) is not illegal or criminal.The spiral reamer (punch) is just ordinary industrial tools, not control apparatus. Of course, if the sale of the spiral reamer, no business license, fake and shoddy products, unknown source or origin, is illegal, but it is also a concept.A reamer is a rotary tool with one or more cutter teeth for removing thin metal on the surface of the machined hole, a rotary finishing tool with a straight edge or a spiral edge, used for reaming or repairing holes.

Q: Hole diameter requirements 30, 0-4 wire, what specifications of the reamer?: This is to use the corresponding D30 (H7) reamer, of course, D30 (H8) can also choose. These will take longer.

Q: When reaming with carbide reamer, there will be a spiral mark on the hole wall. What's the problem?: It depends on what material you are working on.

Q: 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.

Q: NC machining, the speed and feed of the reamer: There is no accurate data, only experience,,Question is not very professional, do not know how much,With the material, but also with clamping rigidity, tool rigidity, tool size, margin, the requirements of the accuracy of the drawings and so onNot a unified answer, in fact, the actual situation depends on the processing of the scene to determine the speed and feed,Adjust at any timeNow let me tell you something about my operation. I do horizontal boring and millingGray iron, milling cutter, assuming 200--300, speed 100--200, the fastest 250 mm depth of 10 mm 1--2 feedDrilling, high-speed steel drill bit, 40 bit, speed 60--150 between 0.4--1 mm, as the size of the drill changes, the speed and feed will also change,End mills and keyway cutters, speed 60--80, feed 0.4--0.8Boring, boring. Assuming the diameter of 100 holes, boring bar 60 thick, length 200, speed 200--300, feed 0.26--0.63 precision boring: margin 0.8--1.2, speed 350--550., feed 0.1--0.17Reamer, cutting allowance 0.1, add oil, feed speed 15--30, 0.6--1.5 mmThe above is my experience, the premise is that you must sharpen the tool,I always feel like a clip on a knife, and I don't always have the tools to sharpen it by hand
