Drill bit, looks a little one, but it is still very expensive to use the installation. Familiar with it all know. Let's take a look at what it is worth noting.
First drill installation. Slowly put the drill box body, the drill box box of the four legs corresponding to the drill into the four holes, according to the drill bit size selection of the corresponding drill box core board, put the drill box core board into the drill box body and then Install the drill groove corresponding to the tip of the drill box core plate, the drill bit into the drill box, the drill card is placed on the turntable heart. And then turn on the drill pipe nut.
Then, the drill bit is disassembled. Lifting drill pipe (with drill bit), the drill box requirements and the turntable connection, lifting the drill pipe slowly to the drill groove and the drill box core plate corresponding to the corresponding, the drill bit stuck in the drill box, followed by retreating drill pipe.
This is the installation and removal of the drill bit. Drill is a rotating and the head end of the cutting capacity of the tool, generally carbon steel SK or high speed steel SKH2, SKH3 and other materials, by milling or rolling and then quenched by heat treatment after grinding for metal or other materials On the drilling process. It is used in a wide range, can be used in drilling machines, lathes, milling machines, hand drill and other tools used on the machine. Drill according to different types can be divided into the following:
A, according to structural classification
1, the overall bit: drill top, drill body, drill handle made by the same material as a whole.
2, end welding bit: drill top parts made of carbide welding.
B, according to drill classification
1, straight handle bit: drill diameter of φ13.0mm below are used straight handle.
2, taper shank bit: drill handle for the cone-shaped, generally its taper are used Mohs taper.
C, according to use classification
1, the center drill: generally used for drilling before the center of the hole, the front cone has 60 °, 75 °, 90 ° and so on.
2, twist drill: the most widely used in industrial manufacturing a drill.
3, super-hard drill: drill the front or all of the hard alloy tool material made of drilling materials used in processing.
4, oil hole drill bit: drill hole has two holes, cutting agent through the hole to reach the cutting edge part to take away the heat and chips, the use of this drill general rotation of the drill and the drill still.
5, deep hole drill: the earliest for the barrel and stone package of drilling processing, also known as barrel drill bit. Deep hole drill for the straight groove type, in the tube to remove a quarter of the strong part to produce cutting edge chip.
6, drill reamer: front for the drill, rear reamer. Drill diameter and reamer diameter only reaming hole margin, there are drill bits in the screw tapping mixed use, it is also known as mixed drill.
7, taper drill bit: When processing mold inlet can be used when the taper bit.
8, cylindrical hole drill: we call it the head cutter, this drill has a smaller diameter at the front part of the pole called the rod.
9, tapered hole drill bit: for drilling tapered hole, the front angle of 90 °, 60 ° and so on. The chamfering knife we use is one of the tapered bore bits.
10, triangular drill: a drill used by the drill, the drill handle made of triangular face so that the chuck can really fixed the drill.
