There are definitely many moving parts in machine tools, and if your machine is not running, it means you can not make the product, which means you're not making money. Every time you start the car, you may look at the fuel gauge to see if the car still has enough fuel. But before you turn the key, do you see the voltmeter? Have you ever wondered if the battery will have enough power to light the car? You may not have thought about this problem sometimes. Because your battery may not have been a problem. But when you drove past a car parked on the side of the road, the hood was open and you never wondered what went wrong with it. I think they must think yesterday that the car can work fine. Just like your car, the machine also needs basic maintenance to prevent it from "stopping on the curb." Moving parts need to be lubricated, need to add oil again, the filter also needs to be checked. In order to keep the equipment functioning properly, routine maintenance work is required. Haas engineers have done their best to keep equipment maintenance as simple as possible. For example, the level of coolant can be measured directly by the sensor and displayed on the screen. These are for debugging and maintenance time-consuming. Haas engineers will usually need to check out the project are listed, for example, the machine's air supply and water supply separately. Haas' machines not only have obvious air filters and regulators, but also a less obvious dump valve that collects any water that may be trapped in the air supply system and then removes them every time they use an air nozzle. This completes two things: 1. Clearing the water in the circuit; 2. Water sprayed through the air nozzle warns the user that there may be a problem with the air supply system. Other aspects of maintenance Here are some key points to watch out for: Safety First Turn off the power and disconnect the air switch in the electrical cabinet before making any maintenance (refer to the normal shutdown procedure). But you have to remember that you can not get an electric shock, especially the high voltage of 480 volts. Routine cleaning Wipes the surface of the machine, including the top; you may not expect so much dust, dirt and debris to deposit on the surface of the machine. If not cleaned, the dirt will enter the interior of the machine and contaminate the cutting fluid. Even into the distribution box, and that place must not have metal debris (which may cause leakage, sparks, short circuit, etc.). If possible, try to clean the inside of the machine. If the machine has a flush hose, use it to wash away dirt and debris generated during the process. Never use compressed air to clean the inside of the machine, as blown debris can harm you and debris can wedge into the machine guard and spindle causing a variety of problems. Safety doors Machine doors and windows of the glass has a special protective effect. Because it is often in the cutting fluid and chemical etching. Its intensity will gradually weaken. The most harmful cutting fluid is mineral oil, coolant suppliers will provide you with information about cutting fluids of their different compositions. When using cutting fluids that are too aggressive in chemical composition, be aware that the protective glass loses 10% of its strength each year. Therefore, you must have regular replacement of their preparation. We recommend that you change it every two years. If your guards have significant damage or serious scratches, they should be replaced and, if cracked, they must be replaced. Lubricants All haas machines (except the toolroom and gr series) have an automatic lubrication system for linear guides, ball screws and spindles, each requiring a specific amount of lubricant. Haas engineers have simplified this process by automatically adding lubricant as long as there is enough oil in the tank. The entire system will automatically lubricate all lubrication points through the flow control valve to ensure that each component gets the right amount of lubricant. cnc system will control the interval at a certain time interval. The automatic lubrication system consists of a pump, a fuel tank and an inline filter mounted on the air / lubricant control panel at the rear of the machine. Check the reservoir daily and fill with oil as specified in the operator's manual. The oil reservoir has a capacity of about 2.5 quarts, often enough oil. The built-in filter, installed inside the oil reservoir, needs to be replaced once a year or replaced after 2000 hours of operation. Although it takes extra time to replace the filter, keeping it clean saves you equipment maintenance costs and downtime. Coolant and cooling tank for each shift shift should check the stock of coolant. As mentioned earlier, the liquid level sensor for the coolant shows the stock in the cooling tank on the screen. This feature is standard on all haas grinders and lathes with split coolant tanks And micro-grinder except). Coolant indicators are displayed on the current command page (the current command page shows all currently running programs). If the coolant drops to a certain level, the warning light will flash. At this time must be added coolant, to avoid pump cavitation phenomenon and cooling fluid phenomenon. Coolant tank ebb and flow Haas coolant tank, built in a filter in front of the pump, need to be cleaned once a week. The coolant tank itself also needs to be cleaned once a week. When cleaning, open the lid and remove any deposits. When the coolant is returned to the pump, the canister is engineered to force the coolant through a series of baffles. These baffles allow sediment and debris to float in the coolant. Be aware that all parts of the tank should be cleaned. Coolant filter The haas machine comes standard with a coolant filter system. For the optional spindle cooling system and lathe high-pressure cooling system, a filter can be added. The filter box is installed near the machine / pump / tank. The filters need to be checked daily, and should be cleaned when the indicator shows that the flow is restricted. On grinders with tsc and lathes with hpc you have to re-fill after changing or cleaning the filter. Allow the system to run for at least 1 minute while filling to fill the filter body and expel the air from the system. Note: There is no tool on the spindle when filling the system on a milling machine. Replacing the coolant Coolant should be changed every 6 months. Discharged coolant should be handled properly and local laws and regulations should be observed as most types of coolant are considered hazardous waste. When draining the coolant, it is best to open the lid and thoroughly clean the inside of the tank, the filter and the pump body. Also check for coolant hose leaks or cracks and replace if necessary. Local hfo service department can provide you with replacement parts, generally do not need to order parts from the factory, haas robotic service goal is 99% of the spare parts can be delivered on the same day to ensure that customers can promptly replace spare parts. Coolant types haas all use water-soluble synthetic coolant. Using mineral cutting oil can damage the rubber parts of the equipment. Using pure water as a coolant can cause corrosion (rusting) of the internal components of the equipment. Flammable liquids must never be used as coolant, otherwise catastrophic consequences may result. Machine transmission with transmission also needs to be cautious. In order to keep the transmission low noise and normal operation, the transmission oil needs to be replaced once a year. Just like the driveline used in your car, there is usually a drain plug on the bottom. Remove the drain plug, the used oil to exclude, pay attention to proper disposal of waste oil. Put the drain plug back into place (this is a very important part), and then re-inject the correct model and the appropriate amount of transmission oil. Your operating manual contains instructions on the type of transmission lubricant. Milling machine spindle pressure haas grinding machine shaft is supercharged, in order to promote the flow of lubricant to the support point. This positive pressure also helps prevent debris and coolant from entering the internal spindle taper. The air pressure should be checked weekly and the control valve mounted on the air / lubricant control panel at the rear of the machine. You can find the correct pressure setting in the operating manual. It should be noted that the optional shaft sometimes have different pressure settings standard shaft, please refer to the operating manual. Machine Tools Some simple machines do not have the same complicated shell or automatic lubrication system as other haas machines, but they still require good maintenance. Linear guide need manual lubrication with oil gun. To simplify this task, the grease nipple is mounted in an accessible position without removing the control panel. Although these machines are simple to operate, there is still no reason to ignore their key moving parts. Of course, do not overfill, this will be detrimental to the seal, with a gun point twice is enough. Tool changers Tool changers on haas grinders fall into two categories: side-mounted and hatshaped. There is a gearbox on the side, with oil checking and cleaning on top. Tool changing arms (both arms) require regular cleaning to prevent debris from accumulating on their surface. Debris build-up can result in the tool changer dropping the tool, damaging the tool or table, and even injuring the operator. The hats and tool changers need to be thoroughly cleaned and lubricated once a month. Care should also be taken during cleaning to remove debris and dirt from the v-rails under the tool changer. Debris build-up can cause the converter to plug. The hanger and tool changer remove the tool while it is being lubricated, and finger the grip of each tool to lightly lubricate. Also slightly v-shaped rails. Routine Maintenance (Screen) The reality is that the first thing you do after entering the shop may not be checking your device, but it's possible to get a customer's call, a custom product ... haas software engineers understand you Difficulties and trying to get your job done, for example, you check lubrication methods, coolant filters or whatever. haas cnc control interface is very friendly, it will show the need for regular maintenance of the content. It is like an electronic calendar reminding you to do the routine maintenance work. In the current command display, you can see the maintenance page by turning the page three times. You will see a list of items that track the history of booting or the time it takes to recycle. Each item on the list can be turned on or off by a mouse click. When an item is turned on, the default value (figures in hours) is displayed and the operator can change this number. When the number becomes zero, a prompt for maintenance expiration appears at the bottom of the control screen. This is not a warning, nor does it interfere with the proper operation of the device, except that it prompts attention to an item in the list. Therefore, these recommendations are instructive, and different techniques and ways of operating the machine may require different cycles of care. The haas manual mentions the details of equipment maintenance and gives some service information needed for additional items such as the hydraulic power unit at the haas steering center.
