Tip: If you are using a high speed steel drill bit, you must first use a center drill. Then drill again. This ensures the correct position of the hole. If you are using a carbide drill, it is not necessary to center the drill first because the carbide drill has a self-aligning tip. If you use a carbide drill to drill a hole that has been subjected to a center drill, the drill bit will be damaged. The outer cutting edge contacts the tapered wall before the bit begins to cut. This can cause an impact on the cutting edge and cause the bit to break. Carbide drill bits must first be cut from the tip of the tool before the outer cutting edge is used. Previous Next TCS series electronic Platform Scale consists of scale frame and instrument.

These tool materials are available in a variety of coatings to enhance their performance. The three most commonly used coating materials are titanium nitride (TiN), titanium carbonitride (TiCN), and titanium aluminum nitride (TiAlN). The gold of the TiN coating is very easy to identify. The advantages of TiN coatings are higher surface hardness, longer tool life, better wear resistance, better lubricity, reduced friction and reduced edge build-up. TiN coatings are mainly used to process low alloy steels and stainless steels. Compared to TiN, the TiCN coating is gray in color and has a higher hardness. The advantages are higher cutting speeds and feed rates (up to 40% to 60% compared to TiN), faster metal removal and excellent wear resistance. TiCN coatings can process all materials. The TiAlN coating is gray and black and is mainly used to process cemented carbide. Suitable for very high processing temperatures up to 800 ° C, making it ideal for high speed machining where coolant is not used. It is recommended to use compressed air to remove chips from the cutting area. This tool is ideal for hard steels, titanium and nickel alloys, including abrasive materials such as cast iron and high silicon aluminum.
The number of grooves or the number of cutting edges is an important factor when selecting end mills. The more slots in the end mill, the smaller or narrower the slot size. The center solid portion of the double-groove end mill is approximately 52% of the diameter of the end mill. The center portion of the three-slot end mill is 56% of the diameter, and the center portion of the end mill with four slots or more slots is 61% of the diameter. This means that the more slots the end mill has, the higher the rigidity during cutting. Two-slot end mills are recommended for softer viscous materials such as aluminum and copper. Four-slot end mills are recommended for harder steels.
Part V: cutting speed and feed rate refers <br> <br> cutting edge of the cutting tool relative to the workpiece moving speed, feet / min (SFM) units. Feed rate refers to the speed at which the workpiece enters the tool in inches per minute (IPM) (or millimeters). Feed rates and cutting speeds affect the completion time of the cut, the life of the tool, the quality of the machined surface, and the power required by the machine. The cutting speed depends mainly on the material to be cut and the tool material. To calculate the correct spindle speed (rev/min RPM), multiply the SFM recommendation by 3.82 and divide by the tool diameter. 3.82 is a constant that converts SFM to RPM. The feed rate depends on the width and depth of the cut, the required surface quality and many other variables. Required feed rate = feed per tooth × number of teeth × spindle speed.
Tip: Can you refer to the mechanical manual? Or other references to calculate the correct speed. Most tool manufacturers offer general tool guidance based on the cutting material required. Many manufacturers even offer on-site service to help you choose the right tool, coating and cutting speed.
Tip: Although the tool speed and feed rate reference information provided by the manufacturer is convenient for your use, it is for reference only. In many cases, these numbers apply to the ideal situation and are therefore not necessarily suitable for practical use. Experience is very important when adjusting tools according to cutting conditions. Vibration may occur during cutting, so it may be necessary to change the cutting speed and feed rate to eliminate these phenomena.
Tip: The Haas control unit is equipped with a standard calculator function to help the operator perform triangular, circular interpolation and milling calculations. To use these features, simply press the HELP/CALC button twice and then use PAGE UP or PAGE DOWN to select the calculator you wish to use. Enter the prompt data and the control device will calculate it by itself.
Setting up a CNC milling machine in the shortest possible time to machine the highest quality parts requires attention to two aspects. First of all, you need to have sufficient common sense. Second, you should be proficient in all aspects mentioned in this article. Many resources provide useful information about these aspects. Haas Automation Machinery's application department can answer all your questions about Haas machine tools and some of the problems you may encounter during machining. In addition, tool manufacturers can also provide consulting services for their products. Finally, you can also find a lot of information on the Internet.
Part VI: automatic tool management <br> <br> user may utilize Haas control monitor machine functions, the machine tool to be used data recording. The control device monitors the tool according to the tool number and records the spindle load, feed time and usage of each tool, and saves this information for the user to use.
Hint: The tool load page is located in the current command display (in either mode, in the current command display, press PAGE UP once to switch to the tool load page). Setting 84, tool overload operation, will determine the machine's response to tool overload. There are four options for setting 84: alarm, feed pause, buzzer or auto feed. The machine will respond when the spindle load exceeds the value entered in the LIMIT% column of the tool load screen. If the tool does not set a limit value, the machine will not respond.
