- Q:The problem of poor chip removal, special reamer scraps can not be found out. What's the main problem?
- The main reasons for the poor chip removal are as follows:1: cutting quantity is too large, feed speed is too fast2: the blade is too many, can change 4 blades for 2 blades3: cutting fluid pressure is too small or blunt point is inaccuratePay special attention to the processing of aluminum material, especially easy to stick knife, pay attention to cutting fluid in placeThe speed of the reamer should not be too high
- Q: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,There is a movable reamer, the blade can be adjusted in a certain range.
- Q:The hole is 9.97, 0.03 margin, but also with 10H7 reamer to hinge it?
- Each knife distribution margin will be not the same, you are asked to assign allowance Oh, recommended by electroplating diamond reamer, you do not know the accuracy is not high, if the demand is high, is recommended by electroplating reamer, it can be divided into coarse and fine reamer to hinge, to consult Henan stone diamond reamer.
- Q:What's the difference between a bore cutter and a reamer?
- In general, a reamer is fixed size tool, cutter is adjustable size tool.
- Q:What's the result of the reaming of the inside hole of the reamer?
- 1, the reason may be the drill spindle and the workpiece hole is not concentric.2. A rotary tool with one or more cutter teeth for removing thin metal on the surface of machined holes, a rotary finishing tool with straight or spiral edges, used for reaming or repairing holes. A rotary tool with one or more cutter teeth used to remove the thin metal layer of the machined surface. After the cutter processing after the hole can obtain the exact size and shape. Reamer for reaming workpieces have been drilling (or hole) after machining holes, mainly in order to improve the machining precision of hole, reducing the surface roughness, tool is used for finishing and semi finishing machining of holes, generally small machining allowance.
- Q:To machining M8, blank hole reamer processing thread with what specifications of the machine (bottom)?
- A drill with a diameter of 6.7 and a M8 tap (also called a tap). Not reamer. There is in the Baidu library, you enter the "drill thread bottom hole" see,Your 7H in the thread accuracy level is a rough level, there is no need to use reamer, and you find 6.7 of the reamer to find it? The internal thread accuracy is divided into three grades, precision, 4H, medium, 6H, rough, 7H. GB recommended using 6H.
- Q:Can we use milling cutters instead of reamer to process holes, the accuracy of holes H7
- With the milling cutter hole processing, smoothness, wear resistance and hole verticality without reamer processing is good, so if only a small amount of processing holes, or the requirements of the hole is not very high, then use the milling cutter will also go.
- Q:When reaming the piston pin hole and connecting rod copper sleeve, how much is the pin allowance?
- Repair the car when the hinged piston pin hole and the connecting rod copper sleeve hole is generally used manual reaming holes, more than the amount of not more than 0.2mm, margin will put the heating hole reaming Reaming with best ream, plant oil, reaming allowance of not less than 0.05mm, the low margin is not hinge hole light. The roughness is not standard, affect the service life, the conditions can also toggle, low speed, feed to slow, do not reverse or scrape pores, also use vegetable oil to stop hinge, hinge reamer can lift it up and out. Reaming allowance 0.05mm-0.2mm.
- Q:The sale of these spiral reamer (punch) is illegal? Crime?
- I don't see the thing, but there's one principle: it's lethal! For example, if you have this thing, it is sharp... Long, let's see, you know, this thing is used to kill people... OK, suspected of committing a crime, may constitute a crime of illegally controlling a knife.
- 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!!
- Not too fast. Sooner, there will be errors
