The most crucial and important aspect of a CNC cylindrical grinder is its CNC system, which is also the biggest difference between it and ordinary grinders So, when the equipment malfunctions, we can make some comprehensive judgments to quickly find and solve the problem, so as to better use the CNC cylindrical grinder and make it play its due role

　　CNC cylindrical grinderThe fault diagnosis can be based on the following methods or criteria:

Intuitive method: It mainly relies on some abnormalities to make judgments, such as abnormal noises, sparks, odors, abnormal heating, etc., and then further judgments are made This is the simplest method, but it requires maintenance personnel to have some maintenance experience

Using the hardware alarm function of the CNC system: it is to use the alarm indicator light to roughly determine the location of the fault

Utilizing the alarm function of CNC system software: Generally speaking, CNC systems have automatic diagnostic functions to quickly diagnose the system. Once a fault is detected, it will be displayed through a display screen or alarm light Therefore, we can use it to determine the location of the fault

Using the detection terminals on the circuit board: Because there are detection terminals on the circuit board, they are used to detect the voltage and waveform of the circuit and check whether the circuit is working properly So, we can use it to diagnose faults

How to use and adjust the CNC cylindrical grinder correctly

1. Application and adjustment of bed frame

The bed is a box shaped casting The front part of the bed is used as an oil tank The electrical equipment is placed on the rear right part of the bed, and the oil pump equipment is installed on the wall at the rear of the bed

2. Application and adjustment of workbench

The workbench is mainly composed of an upper table and a lower table Loosen the hexagonal screws on the two pressure plates of the upper table, roll the adjustment handle, and the upper table can be reversed within a regular range to adjust the taper of the workpiece After turning the upper table to the desired viewpoint, tighten the hex screws of the two pressure plates before grinding The label on the right pressure plate has two types of markings, one indicating taper and the other indicating share When the tabletop rolls more than 6 degrees, the grinding wheel holder must rotate to a certain viewpoint to avoid collision between the tailstock and the grinding wheel holder

　　CNC cylindrical grinderReasons for generating vibration patterns

1. Workpiece vibration: In addition to the influence factors of electric motors, pulleys, and belts, the lower the rigidity of the workpiece ejector pin system, the greater the frictional force of the grinding wheel on the workpiece, and the more severe the vibration of the workpiece Poor contact between the ejector pin and the center hole of the workpiece, such as the center hole having a polygonal shape, a small contact area of the conical fit, or poor fit between the ejector pin tail and the conical holes of the headstock and tailstock, can also cause vibration of the workpiece Excessive lateral and longitudinal feed rates, as well as a dull working surface of the grinding wheel, can cause the workpiece to vibrate and produce ripples

2. Uneven wear on the working surface of the grinding wheel, bluntness of the grinding wheel, system vibration, and uneven hardness of the grinding wheel can all cause vibration and ripple generation

3. Grinding wheel vibration: If the various components of the grinding wheel and the transmission grinding wheel are not balanced or run unevenly, it can cause grinding wheel vibration. The main reason is that the grinding wheel is not balanced well, followed by the imbalance of the motor and pulley of the transmission grinding wheel. The uneven thickness and length of the transmission belt can cause the belt to become loose and tight when it expands, and even slip; In addition, the clearance between the grinding wheel spindle and the bearing is too large, causing ripples in the vibration generated during the rotation of the grinding wheel

When operating a CNC cylindrical grinder, close attention should be paid to the contact condition between the grinding wheel and the workpiece surface When the surface of the workpiece comes into contact with the grinding wheel, a continuous hissing sound can be heard, and the water stains on the surface of the workpiece can be carried away by the rotating grinding wheel. At the same time, weak sparks can be seen. At this time, coolant can be added The coolant should be selected from a slightly higher concentration saponification solution, which must undergo strict cleaning and filtration before use Then feed, with a feed rate of 0.005mm per pair of strokes When the spark disappears, the grinding is completed. At this point, press the lateral feed handwheel in the feed direction to slightly press the grinding wheel into the workpiece without feeding, which is equivalent to polishing the workpiece once to further improve the surface quality of the grinding

Scope of Application

(1). Used in the textile industry such as cotton spinning, wool spinning, polyester spinning, ammonia spinning, linen spinning, chemical fiber spinning, glass fiber spinning, synthetic fiber spinning, etc., for processing rubber rollers and hoses in mechanical stretching devices such as coarse and fine yarn machines, drawing machines, combing machines, puffing machines, double twisting machines, and splicing machines

(2). The CNC cylindrical grinder is used for the production and manufacturing of automatic conveying devices in the office communication equipment industry, printing, food, and pharmaceutical industries. It is used for the processing of surface rollers, rubber rollers, rubber hoses, adhesive tapes, rubber wheels, and plastic wheels

(3). The vacuum cleaner can be replaced with a water cooling system to finely grind the outer circles of optical instrument glass, power ceramics, mechanical hardware, and other materials
