Q:1.5 of the stainless steel plate to drill 1.2 holes, the drill has broken a lot of roots, what kind of material with a bit better? How much speed, how much feed?
1.2MM drill bit processing stainless steel cutting dosage is recommended as follows:Cutting speed / (m/min) 15 feed f/ (mm/r) 0.05 drill bit helix angle / (degree) 25-35 drill point / (degree) 118-135 high cobalt high speed steel
Q:What's the difference between a drill bit and a tap?
A drill is a tool for drilling; a tap is a tool for cutting threads in a hole. That's the difference between them.
Q:How to allocate the electric hammer drill
Electric hammer drill, is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill reciprocating hammer exercise. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
Q:What brand of drill iron?
The key of the bit selection is not the brand, but the choice of the drill bit.
Q:Angle action and characteristics of standard 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.
Q:What drill holes are used in stainless steel basins?
It is better to use stainless steel drill in stainless steel drilling. And the feed amount is greater than 0.15mm, so as not to cut the cold work hardening layer as much as possible. The cutting speed is as low as possible to reduce the cutting temperature.
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.
Q:Is there a standard for drilling errors due to machine tool shaking?
But the drill is drilled out of Kong Shizheng because the bit will wobble during drilling so that the drilled hole is out of turn.
Q:Small bit drilling, drilling machine speed is fast or slow?
This size is easy to guarantee. A drill bit is to make two cutting edges for the small angle grinding symmetry, if you want to drill the round, can put some small angle grinding, namely some sharp, this bit in drilling, centering is better, the hole wall is relatively light.
Q:What do you mean by 5 times diameter drill?
5 times a bit is the drill depth that can reach 5 times the diameter of the drill. For example, a drill with a diameter of 10 can process 50 deep holes.
