Q:How big bits are used for expansion bolts?
The required diameter of the expansion bolt is the same as the diameter of the expanding tube (Note: not the diameter of the bolt).
Q:What drill is used for punching aluminum parts?
There are aluminum alloy bit, select M42, M35 or 6542 bit.
Q:Types of impact drills
There are two types of drill hole two groove round handle (usually produced abroad and anti hammer production abroad is used), four hole square shank (general domestic production of electric hammer used) and five bit six bit long pit, angle etc.. Hope to be of help to you.
Q:What kind of drills are commonly used in CNC machining centers?
Shallow hole drilling: in the processing center use, usually will use indexable shallow hole drilling, that is, with the alloy blade of the drill bit, use this kind of drill, generally require the machine spindle has internal cooling device, otherwise it will reduce processing efficiency.Deep hole drilling: as its name suggests, it is a drill bit used to process deep holes. Its diameter and length are relatively large. Generally, there are 2 guide blades on the side edge.Center drill: used to prevent hole change during drilling and to use when locating holes.Centering bit: a better positioning capability than an ordinary bit, usually used for centering holes or for machining thin plates. The difference between a drill and an ordinary drill is that the method of grinding is different.Drill: drilling reaming drill to drill, no vertex, generally between 0.5-2MM for reaming, reamer used with.
Q:How can we change an ordinary drill bit into stainless steel?
With ordinary stainless steel drill bits to drill, speed down, such as 100, add a little vinegar when drilling well drilling. In two, the lowest drill about three hundred rpm, speed a little faster. It is better to drill on the vertical or rocker arm, and the speed can be adjusted lower.
Q:What method should we pay attention to when drilling small holes and long holes in plain drills?
When drilling a deep hole or a long hole, the workpiece must be fixed. Drill the hole with the center first, then drill with the bit so that the drill will not drill the hole when it is drilled.
Q:What measures can be taken to prevent the bit from breaking?
In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit. Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.
Q:The threaded hole M5 general drill big bottom
General drilling screw threads diameter can be directly check the manual or by the following formula:Brittle materials (cast iron, bronze): bore diameter D=d (thread outside diameter) -1.1P (pitch)Plastic material (steel, copper, etc.): drilling hole diameter D=d (L thread diameter) -P (pitch)
Q:How to polish drill bit?
An angular grinder cannot grind a drill bit. You must grind a drill bit on a sander, and you are a layman, and you may not sharpen it even if you have it.There are so many fake twist drills, you can only buy them and buy more.
Q:The basic angle of twist drill
The main deviation angle is RM, and the main angle is the angle between the tangent of the main cutting edge and the feed direction of the m. The base surface of the twist drill is the plane at which the main cutting edge is selected, including the axis of the drill bit. The bit is not the main cutting edge through the axis line, so each point on the cutting edge of different base, the main angle points are also different. When the angle of grinding, the main angle can be determined. The main deflection angle and the vertex angle are two different concepts.
