Q: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.

Q:Why reaming with reamer is the workpiece of ductile iron 500, the aperture will be smaller, and the aperture requirement is 9. After reaming, the reamer will not enter the hole. What is the reason why the hole is too small for the reamer to go in?

The precision can not reach. BECK-AUGUST world's top producer of precision cutting tools. BECK has 90 years of production experience and the most advanced production equipment, with its excellent product design and manufacture in the world leading drilling tool production, the non-standard cutting tools with the characteristics of high quality, precision has been widely used in automotive, aerospace and other fields.BECK single blade hinge adhering to the clamping tool not grind all the advantages, when the cutting tool wear or failure, as long as the replacement of the knife, a slight adjustment can be put into production. The fine adjustment mechanism can precisely and flexibly control the diameter of the blade and reverse the cone to meet the processing requirements. The whole process guide bar made of hard alloy, metal ceramic or artificial diamond can effectively control the treatment accuracy. I suggest you try some of your homemade reamers.

Q:What causes shrinkage hole after diamond reamer machining?

Large deformation of aluminum, increasing width of tool edge!

Q:Machining center with 4MM and 6MM white steel reamer, 45 steel material, spindle speed and feed speed settings how much ah!

What size of allowance do you have?. You seem to have a small amount of feed. You use a thinner reamer and do not know how large the main deflection angle of your reamer is. If your reamer is machined to the end, there is a slight effect and the force is complex. When the chip is in a disc shape, it is difficult to discharge, and the friction between the wall and the hole is severe, so that the tool can be easily broken.It is recommended to reduce the amount of cutting and wear a certain main angle of deviation. If the aperture is relatively large, it is recommended to carry the knife often.Try using a small cutter instead of a reamer. Or buy a screw reamer directly.

Q:What is the tolerance of the reamer for 16D4?. How can't you find out in the tolerance list?

16D4 is the old standard basic shaft system with the hole, relative to the new national standard for H8 H9 (between H8 and H9 between the tolerances). I hope I can help you.

Q:The number of drills and reamers for diameter from 1 to 20.. The more detailed, the better

With 45# steel as standard, the speed of drill is 450/S, the feed is F250, and the reamer is 500/S

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:How do you choose the tolerance of reaming when reaming?

The processed reamer size with many factors, such as what the coolant, cutter speed, feed rate, exit reamer also pay attention to.The standard reamer is generally the axis system size. Such as H8, H7, H6. Of course, also can according to the hole size to build special dimensions and tolerances of the reamer.The theory of pore size is negative to wring size zero. But the actual wring hole must be more than theory. General tolerance of hole is smaller, the precision is higher.The general processing speed is slower, the cooling liquid, fully feed more quickly, the size of the hole is out of tolerance near.

Q:With a machining center, the diameter of the hole is 28, and the cutting amount of the reamer when reaming

Such a big hole, why not boring.

Q:Four what are the advantages of titanium blade reamer
