Q:What are the causes of internal bore runout in lathe reaming?

The tailstock is missing. Look at it

Q:Would you like to make a straight hole reamer with an outer diameter of 32, an inner hole of 12, and a tolerance of -0--0.02. The inner hole and reamer must be concentric. How can I do that?

Buy a ready-made, similar diameter, straight hole, hand or machine reamer. On the universal tool grinder, a little change will be made. However, tolerance selects 7 stage sharpening! For reference only!

Q:Please enlighten brother snow reamer 150125110 motorcycle valve is not universal and how the hinge valve

If you are a car should know how much money you don't need to change itTo hinge the valve, one is trouble, two is time spent more, in addition, after the hinge, the quality is not absolutely guaranteedAs the car is definitely so simple to make money do try not to engage in some trouble things a car down half lost there costs time and effort as a direct change covering more simple

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

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:Can the machine reamer be installed on the milling machine?

All right。 The machine reamer can be installed in the milling machine. Drilling machine. CNC machining centers are available.

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:CNC lathe reamer, how to hinge out 0.4 of the smoothness?

Coarse hinge and precision hinge,The reamer must be correct,When reaming, lower the allowance, add kerosene or vegetable oil.If my answer is helpful to you, please accept it as the best answer in time. Thank you!

Q:The difference between the reamer and tool?

The cutter can not be changed, change the boring tool

Q:Four what are the advantages of titanium blade reamer

After TIN plating, the blade life is prolonged, and secondly, the machining ability is improved. If the titanium plating, then do not use cutting fluid. Cost saving.
