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

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

On such a small hole with white steel, with steel spiral machining cutter Wu did not know, processing thousands of hole can not use a knife, also used a certain blind hole you don't end up blowing again twisted twisted down will be a good point, cutting knife is mainly iron row is not good, or high speed feed slow knife wear quickly........................ there are.....

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 want to lay 17 hole diameter, valve hole of steering pump, recently the old material is out of order, gray cast iron, which has two cross the oil window, leaving 30 wire end hinge margin, to reach 17 by 5 wire with diamond reamer reaming finally reached 17+0.008mm, but sometimes twisted lax that is the total crude hinge traces, do not know why. Master, tell me why? How to choose the cutting amount, how high the speed, what choice to do cutting fluid? The speed of feed and retract? We use emulsion, right? Thank you

The margin stayed large. The fine hinge was pushed through the surface. The last one was left with 3 wires. Gray iron emulsion is good, 45 turn, stop the knife.

Q:Which is the higher accuracy of the reamer and reamer?

Of course, the reamer, reamer expansion tensor or contraction in less than 0.005~0.02, reaming, drilling, expansion tensor in 0.05~0.1

Q:The machining center CNC uses reamer to lower the reamer oil. Should the spindle be turned or reversed?

This must be turning!

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:What's the result of the reaming of the inside hole of the reamer?

The prefabricated hole too, the outer circle of the elliptical reamer reamer, do well. There is a problem with the accuracy of machine tools. Do not understand, we drill bit drill did not appear elliptical hole Oh.

Q:What is CNC reamer?

Generally refers to the single indexable blade reamer (currently only international companies only), such as Sweden and Germany is MAPAL indexable single edge reamer, cutting smoothly without vibration, high machining accuracy, reaming allowance, high cutting speed, shape and position error is small, long tool life;But some people put the reamer in the NC machine tool called NC reamer, the scope is big, a reamer, common straight shank machine machine reamers with adjustable pressure, expansion reamer, reamer taper and taper shank reamer etc..

Q:What's the difference between a bore cutter and a reamer?

In fact, from the number of edge cutting is not what special distinction, and a single blade Boring Reamer and multi edge points. Mainly from the processing technology to distinguish the reamer just to get better precision holes, generally on the machine are low, processing is relatively simple, the position of the size precision boring not only can get a better hole hole can also be modified!!
