For CNC machining parts, as long as the CNC processing the equipment has a good reputation and reasonable price, CNC machining parts has a leading edge in the industrial market. However, CNC machining parts manufactories often overlook the operation and maintenance of the most important CNC machining parts. The key to preventive maintenance of CNC machining parts is to strengthen daily maintenance.
Just like most current technological devices, most problems of CNC machining parts are caused by user error and lack of maintenance.
If your material has burns on the outside edge: Usually, CNC machining parts either has a blunt tool or too low of a feed speed. Check out if your feed speed is right for the material you’re cutting. Simply replace your dull tool of CNC machining parts with a sharper one or increase your feed speed.
Making the same mistake twice: CNC machining parts takes a lifetime to learn. At no point should you consider yourself a master who has it altogether. New situations happen that require new thinking and adaptation even by experienced experts.
Chatter: When your chatters of CNC machining parts, it simply means it vibrates when doing its job. Chatter happens either to CNC machining parts or just its tool. Chatter harms the quality of CNC machining parts, dramatically reduces the life of your tool, and can even shorten the lifespan of your CNC machine too. To prevent chatter from ever happening in the first place, simply make sure your cut width or depth keeps deflection below 1/1000th of an inch.
Overheating which can cause your entire CNC machining parts to fail: CNC machining parts can reach more than 150 degrees on the inside. Filters can get clogged with dirt and debris, which can push temperatures even higher. This can cause serious damage to CNC machining parts.
Prevention of CNC machining parts mostly consists of routine maintenance. Have a regular schedule for clearing dirt and dust from your AC units and filters. Cutting fluids and metal shavings should be cleared away routinely, as they can contaminate your equipment.
The main maintenance work of CNC machining parts has the following contents: daily inspection, weekly inspection, monthly inspection, quarter inspection, and semi-annual inspection. CNC machining parts preventive maintenance is as follows:
Daily inspection of CNC machining parts: CNC machining parts’ main projects include hydraulic systems, spindle lubrication systems, rail lubrication systems, cooling systems, and pneumatic systems. The daily inspection is based on the normal conditions of each system. When performing the process detection of the spindle lubrication system, the power light should be on, and the hydraulic pump should be running normally.
Weekly inspection of CNC machining parts: CNC machining parts’ main items include machine tool parts and spindle lubrication systems, which should be properly inspected weekly, especially for CNC machining parts to remove iron filings and external debris cleaning.
Monthly inspection of CNC machining parts: Mainly to check the power supply and air dryer. The power supply voltage is rated at 180V-220V under normal conditions, and the frequency is 50Hz. The air dryer should be removed once a month, then cleaned and assembled.
Quarterly inspection of CNC machining parts: The quarterly inspection should be carried out mainly from three aspects: machine bed, hydraulic system, and spindle lubrication system. When inspecting the machine bed, it is mainly to see whether the machine tool accuracy and machine tool level meet the requirements in the manual.
l Reasonable choice of cutting amount of CNC machining parts: For high-efficiency metal cutting processing of CNC machining parts, the processed material, cutting tools, and cutting conditions are the three major elements, which determine the processing time, tool life and processing quality. With the increase in cutting speed, the temperature of the tool tip will rise, which will cause mechanical, chemical, and thermal wear. The user should choose the cutting speed to be used according to the processed material, hardness, cutting state, material type, feed rate, and depth of cut.
l Choose a tool of CNC machining parts reasonably: When rough turning, choose high-strength and durable tools to meet the requirements of large back-grabbing and large feed. When finishing turning, choose tools with high precision and good durability to ensure the requirements of machining accuracy. In order to reduce the tool change time and facilitate tool setting, machine clamped knives and machine clamped blades should be used as much as possible.
l Choose fixtures of CNC machining parts reasonably: Try to use general fixtures of CNC machining parts to clamp the workpiece, avoiding using special fixtures. The part positioning datum coincides to reduce positioning error.
l Determine the processing route of CNC machining parts: The processing route is the movement track and direction of the tool relative to the part during the processing of the index-controlled lathe. It should be able to guarantee the processing accuracy and surface roughness requirements of CNC machining parts. The processing route should be shortened as much as possible to reduce the tool idle travel time.
