- Q: Which is better, a white drill or a black drill?
- Black becomes nitrided and can be used to drill aluminum products, i.e., soft materials, after improved propertiesThere are 3 processes for producing drills, black for rolling and worst for rolling. White for clean edges and ground. Because, unlike rolling, no high temperature oxidation, the steel grain structure is not damaged, used to drill a slightly higher hardness workpiece.The yellowish brown drill, called cobalt cobalt drill in the industry, is the unspoken rule of the drill. Cobalt containing drills were originally white, produced by grinding, and when they were atomized at the later stage, they were made of yellow brown (commonly called amber), which is the best in circulation. M35 (Co 5%)
- Q: Relationship between bit diameter and rotation speed
- Secondly, it is related to the grinding, feed size, material and so on. Such as: stainless steel drilling, the drill speed and feed volume should not be too large, the need for flexible use.
- Q: Is there a standard for drilling errors due to machine tool shaking?
- Is the drill drill a positive or negative deviation, or is it bigger or smaller?. Bit wear is not serious, the drilled hole is a positive deviation. If the drill is used for a long time, the ligament is worn badly and the drill is worn out too, and the hole drilled is a negative deviation
- Q: What bits of percussion drills are made of?
- Features: with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
- Q: What measures can be taken to prevent the bit from breaking?
- I. to drill through, reduce the pressure. Slow down. Two. Drill the bit into a group
- Q: Tap 10 taps, what size drills do we use?
- Brief introduction of tap:As a tool for machining internal thread taps, according to the shape can be divided into straight edge and screw tap tap, in accordance with the use of the environment can be divided into hand taps and machine taps, made in accordance with the specifications, and can be divided into metric, British tap, according to the origin can be divided into domestic and imported tap tap. Tap is the most important tool for operators to process thread.
- Q: How about the speed of the drill bit and the feed of the cutter in the machining center?
- 1, if I first drill with D13 bit (S600, F80, Q5), and the rest of all milling cutter hole2, casting and steel parts almost turn, the speed can be faster. After 28 of the hole points, use 28 bit S300, F50, Q3. directly3, 35r6 direct spiral down, layer below 0.5-0.8, S1500, F2000-3000
- Q: What is the geometric angle of the drill bit?
- The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..
- Q: When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
- Stainless steel, titanium alloy, steel and other materials hard to be machined: D=d1-0.95P. Still in the case of M10x1.5, hole size D=10-0.95 * 1.5=8.575. (recommendation 8.6)
- Q: What bit is hard, not easy to wear and punch?
- Stainless steel drilling bit, not the problem, of course, is not Never mind, is to buy a bottle of vinegar, vinegar, vinegar is vinegar can be, not tried.
