Our machine including large CNC lathe, CNC machining center, CNC centerless grinding machine, CNC Incisive grinding machine, CNC cylindrical grinding machine, heat treatment machine.
The spindle motor emphasizes strength and high speed. Many times there is no position control requirement, and the speed accuracy requirement is not very high.
Sufficient output power, the spindle load property of CNC machine tools is similar to "constant power", that is, when the spindle speed of the machine tool is high, the output torque is small; when the spindle speed is low, the output torque is large; that is, motor shaft the spindle drive device is required Has the property of "constant power".
Speed range: To ensure that CNC machine tools are used in a variety of different tools and processing materials; adapt to a variety of different processing techniques, the spindle motor is required to have a certain speed range. However, the requirements for the spindle are lower than for the feed.
Speed accuracy: Generally, the static difference is less than 5%, and the higher requirement is less than 1%.
Fast: The spindle drive is sometimes used in the positioning function, which requires it to be also fast.
The feed motor has more emphasis on efficiency, and the feed axis usually has higher accuracy requirements.
The mechanical characteristics require a small speed drop and high rigidity of the servo motor.
Quick response requirements: This is more demanding in contour machining, especially for high speed machining of workpieces with large curvature.
Speed range: This allows the CNC machine to be used in a variety of different tools and materials; adapt to a variety of different processing.
A certain output torque and requires a certain overload torque. The nature of the machine tool feed mechanical load is mainly to overcome the friction of the table and the resistance of the cutting, so it is mainly the nature of "constant torque".
Be sure to pay attention to the following aspects when changing auto parts
Don't ignore packaging information
When buying auto parts, it is easy to find flaws on the packaging and should be carefully identified. Generally speaking, the original packaging box has clear writing, accurate overprinting and vivid color, and is marked with product name, specification model, turning parts quantity, registered trademark, factory name, factory address and telephone number, etc., with certificate and inspector chapter, some important Parts such as generators, distributors, etc., are also equipped with instructions for use to guide the user in proper use and maintenance. Some auto parts will be marked with the origin of "Indonesia", "France", etc., but can not provide relevant import declaration procedures, the authenticity of the product is also difficult to judge, many may be counterfeit products.
No wear on the surface
The surface of the purchased new parts should be free of wear. If the surface is worn or the painted parts are peeled off and the surface paint is found to be old paint, it should be a disguised waste piece. At this time, it must be returned.
Flexible parts to rotate
The steering knuckle is one of the main parts on the steering axle of the car, which enables the car to run stably and sensitively convey the direction of travel. When you purchase a rotating part, turning it will feel no jam and free rotation. When the rotating part does not rotate, it indicates that the inside of the part is rusted or deformed and cannot be purchased.
The joint area should be flat
During the handling and storage of spare parts, due to vibration and bumps, deformation often occurs at the joint. During the inspection of the shaft parts, the shaft parts should be placed on the glass plate or other flat objects to roll. See if there is light leakage at the intersection of the parts and the plane to judge whether the shaft parts are straight or not.
Glued parts are not loose
An assembly made up of two or more parts. The parts are press-fitted, glued or welded. No looseness is allowed between them. For example, the oil pump plunger and the adjustment arm are combined by press-fitting; The clutch driven wheel and the steel piece are riveted and combined, the friction plate and the steel piece are riveted or glued; the paper filter element core frame and the filter paper are glued together; the wire head of the electrical equipment is welded. If it is found to be loose during purchase, it should be exchanged.
No rust on the surface of the part
The surface of qualified spare parts has certain precision and bright finish. The more important the spare parts, the higher the precision, the stricter the anti-rust and anti-corrosion of the packaging. Should pay attention to inspection when purchasing, if the parts are found to have rust spots, mildew spots or rubber cracks, loss of elasticity, or the surface of the journal has obvious turning lines, should be replaced.
