Q: Spindle runout of less than 0.003, the diameter of the cutter size, internal cooling. Excuse me, where is the reason?.: Consider the choice of materials and sizes

Q: 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.: For you the double-edged cutter, S and F on the line four pin gear extrusion

Q: Do reamers and drills for machining centers use one hilt?: One hilt is fine, of course. For example, using ER20 is fine, and the accuracy is fine!

Q: Why are the dimensions of the reamer larger than the size of the hole?: This is certainly bigger than hole cutting tool, the key is you choose how much allowance, allowance is processed in your material, to see if he had deformation like, generally with a diameter of 0.1 to about 0.15mm, is relatively good. Thank you

Q: Machine is a horizontal machining center Huakai, machining hole size is 14mm through hole, the first with 13.5 bits, then the 14 hinge reamer, reamer is 120 speed 320 feed speed, casting hardness is HB170 ~ 241, made out of the hole often bell shaped, reamer blade also day after day grinding, grinding or not, sometimes for a new reamer like bell. Who can help me analyze the reasons?.: You are using a high speed steel cutter, for hard alloy - increase the rigidity decreases beating!!

Q: Processing materials for aluminum parts, unilateral processing allowance of 0.7 mm, four blade is indeed higher machining accuracy, but the row cutting than the three blade almost: Reaming should be four edged reamer, because it is finished, and the blade is a little better

Q: What drill and reamer are used to process an empty diameter of 8mmH7?: Drill with a small bit 2.8mm-4.2mm first, and then use 7.8mm to expand the hole. Then machine reamer 8mmH7. Reaming speed should be slow, small and uniform, add oil lubrication cooling. It can be machined into a qualified 8mmH7 hole.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 drill, comprising a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E) on orientation the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.

Q: When reaming with carbide reamer, there will be a spiral mark on the hole wall. What's the problem?: With spiral reamer and / or reduced single feed of reamer / try to increase the rigidity of the hinge handle, the spiral grain should be eliminated

Q: Difference between milling cutter and reamer: Besides they say, the most intuitive is that the blade part of machine reamer is very short, while the neck is very long, so it looks like a long dumbbell.The end mills have longer cutter teeth, accounting for 1/2~2/3 of the overall length of the tool, and the neck is short. The cutter tooth is spiral and has fewer teeth. It looks sharp.People who don't know much about knives do so.

Q: 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
