CNC grinding machines differ from devices with manual control in that ensuring the productivity of work on a CNC machine often does not depend on the grinding process itself. It is more dependent on reducing the time spent on metal processing and programmed automatic control grinding process.
CNC grinding machines are suitable, as a rule, for the final finishing of surfaces of parts with various abrasives, diamond wheels. This treatment is done by removing the top layers of the metal to give the surfaces the best possible cleanliness.
Such grinding devices perform the following operations:
- stripping;
- cutting;
- cut blanks;
- precision machining of rotary surfaces, gear wheels, sharpening of various tools.
About the types of grinders
Typically, CNC systems are installed on devices of this type:
- surface grinding for processing ordinary planes;
- circular grinding devices for grinding crankshafts;
- internal grinding machines for profile grinding of holes;
- grinding and grinding, for sharpening tools of machine and manual type, cleaning parts, processing welded or simple structures;
- contour grinding;
- sharpening, for locksmith work, such as chamfering, deburring, sharpening any tools, up to sharpening cutters different kind and drills;
- centerless grinding types of devices for plunge and continuous through grinding.
About the technical features of some CNC devices
The manufacture of such machines for grinding work can be associated with certain difficulties, which are characterized by such technical factors:
- on the one hand, it is necessary to achieve good quality and pretty high precision grinding work, with the smallest dispersion in terms of the size of the circles;
- on the other hand, it is necessary to take into account the error in the exact dimensions of the grinding working wheel, depending on its wear.
In such cases, it is required that on such a CNC grinder, there are special mechanisms for automatically compensating for the wear of this tool. Such mechanisms are designed to compensate (compensate):
- some deformation;
- a small error in the temperature regime;
- changes in allowances allowed on workpieces being processed;
- any errors of machine tools for given coordinates.
Important. For these types of cylindrical grinding devices, for example, these mechanisms can provide a constant opportunity to measure the size of the workpiece by diameter during its processing. Moreover, the error in the measurement will not exceed more than 2·10 -5 mm. The longitudinal movement of such a table is controlled with an error of only 0.1 mm.
Usually, for the grinding type of devices, special CNC systems are used (from the English CNC), which are controlled by ordinates from 3 to 4. And if several grinding wheels are involved in the machines, then such control will be carried out along 5-6-8 different ordinates. Moreover, the interaction of the operator with the built-in CNC system is often carried out in a dialogue mode using the display. In addition, to increase reliability, such systems are equipped with special diagnostic modules.
About CNC systems
In order to correctly control dressing mechanisms in machine tools, such software systems are used that:
- are closed to compensate for temperature deformations and geometric inaccuracies;
- have the ability to measure with good resolution, to ensure small tolerances for accurate positioning;
- have the ability to automatically compensate for the wear of the circle;
- will be able to control the frequency of circular rotation, feed rate.
When controlling such CNC systems, it is possible to coordinate the functioning of multi-axis centerless cylindrical grinding devices. For this, the built-in system uses special modules that calculate:
- any trajectory of grinding devices;
- necessary corrective actions;
- mutually agreed dialogue between the operator and the service device.
Important. The existence of multi-axis CNC systems gives more versatility to these production devices, allows you to effectively influence any grinding process.
About circular grinding devices
In any CNC grinding machine, the greatest effect is achieved when processing surfaces with one installation of special multi-stage parts, for example:
- workpiece clamping spindles;
- shafts of electric motors;
- turbine elements;
- reduction gears for rotational frequency control.
In such cases, productivity is greatly improved while reducing overhead time, which is dedicated to:
- setting the required blanks and removing already processed finished products;
- reinstallation for the purpose of subsequent processing of the shaft neck;
- required measurements.
On these circular numerical grinding machines, the programmed processing of various multi-stage shafts reaches the end with a reduction in time of almost 1.5-2 times when compared with a conventional control machine.
About types of centerless grinders
Machines of this type are usually used for:
- processing of various parts, of any length, with large or small diameters;
- grinding parts with rather complex external profiles.
These machines usually have high productivity and very precise processing. But, unfortunately, for small-scale and small individual productions their use is difficult, since it is quite difficult to readjust these devices, since this will require significant time costs, service staff highly qualified.
Such difficulties are associated with the technological features of these grinding machines, for example:
- the existence of leading, grinding grinding wheels in them;
- availability of special ruling devices, which provide the necessary configurations for the surfaces of any circles (grinding and leading type);
- fixing the fixing of the reference type of special knives;
- the presence of mechanisms for compensating the feeds of the desired type of circles, processing products;
- setting the required position for loading and unloading types of devices.
About CNC End-Roll Grinders
Usually, in devices controlled by programs, a large number of coordinates are provided. For example, in a grinding fixture of this type, there can be up to 10 controlled ordinates, of which three are main and at least six are auxiliary for better positioning:
- axial orientation of workpieces relative to the circle;
- displacement of the headstock of the rear type for adjusting and processing workpieces;
- editing circles to ensure the possibility of processing any profiles;
- device axes for active control;
- better turning tables for cone processing.
For processing various types of geometric shapes of products by CNC grinding machines, special programs are installed:
- mode selection manager;
- a special module that controls the drive;
- an interpolator that determines the coordinates of the points.
At serial production such CNC grinding machines are used with the use of software systems, which makes it possible to flexibly adjust the dressing and grinding cycle, significantly affect the speed of machine changeovers and the processing of a variety of parts. In addition, such multi-coordinate systems give more versatility to machines, stable efficiency in managing all processes.
