PURPOSE:
Jig grinding machines are designed for grinding complex shapes and holes, where the highest degrees of machining accuracy are required. According to the principle of operation, these machines are very similar to jig boring machines, but the difference is that grinding machines have a higher processing accuracy (much higher than that of a simple milling or lathe) and the speed of the grinding spindle.
APPLICATION AREA:
Machine tools are used in tool production, the manufacture of dies, matrices, the production of complex modern mechanisms, wave gearboxes, products requiring particularly high machining accuracy, etc. These machines use linear actuators, high-speed pneumatic or electric motors and various systems cooling, both the machine itself and the workpiece.
The machine runs at a high spindle speed. Spindles can be changed depending on the requirements of the processing, in order to achieve an optimal result. Some of the spindles are fixed speed (60,000 rpm), others are adjustable (between 30,000 and 50,000 rpm) and still others are very high speed(150,000 rpm). The main spindle has a wide range of speeds to ensure the desired result. The machines have standard movement axes (X and Y). All axes are indexed to 0.0001 mm using an electronic flywheel. The machine is equipped with high-precision linear drives. The spindle rotates at variable speed and moves with an accuracy of 0.0001 mm for grinding high-precision holes. Only the use of such technologies will make it possible to achieve desired result with precision machining.

For example, mechanical engineering, aircraft building, instrument making, production of profiles, cylinders and boxes is simply impossible without special equipment - sheet bending. Sheet bending machines produce parts from sheet metal materials. sheet bending machines, specifications which are painted in the most detail, have more functionality, which means they can replace some other machines. You can buy sheet bending machines both light (mobile) and workshop (heavier). If you plan to transport equipment from one workshop to another over time, it is better to choose a mobile plate bending machine. Sheet bending machines, the description of which necessarily includes dimensions, are mostly mobile. The configuration of products obtained on a bending machine can be very complex. For example, complex profiles can take the desired shape in several transitions. Sheet benders, the technical characteristics of which vary depending on the principle of operation of the mechanism, are used in the manufacture of body parts from steel and sheet alloys. Sheet benders (rollers), the rigidity and reliability of which ensures high precision in the production of products, do not damage the surface of the sheet during the bending process. It is better to buy sheet benders with the function of unlimited depth of material supply. Sheet benders, the description of which includes the possibility of bending metal at the greatest angle, are considered more functional and convenient to use.
The rollers, the specifications of which may differ depending on the model and manufacturer, can be used in the production of drums, tanks and blowers. Rolls, the description of which includes more than 10 indicators, are divided into vertical, four-roll and three-roll. You can buy rollers that will meet all your requirements. For example, three-roll rollers require minimal maintenance. Three-roll rolls, whose specifications include tools for bending conical shells, greatly expand the possibilities of your production. It is recommended to buy three-roll rollers that are electromechanical, since their performance is slightly higher. Three-roll rollers, the description of which guarantees the ability to make blanks not only for pipes, but also C-, V-shaped products, significantly expand the scale of production.
Sheet bending rolls produce a canonical bend, as well as a preliminary bend of the workpiece. Also, the roll forming equipment is quite easy to use. Sheet bending rolls, the technical characteristics of which include a complete set in the form of a special mechanism for removing products, a tool for bending long products, will cost a little more than rolls with a more modest set. However, if you need to buy sheet bending rolls, it is better to choose models with a wider range of equipment so as not to buy some parts separately. Sheet bending rolls, the description of which includes the function of expanding technological capabilities, are equipped with tools for bending squares, channels, angles, pipes and strips.
Roll forming equipment, the technical characteristics and composition of the line of which may differ significantly depending on the needs of a particular enterprise, always has a flexible price. Therefore, you can buy roll forming equipment strictly in accordance with the requirements of your production, so as not to overpay for additional functions which will never be used. Roll forming equipment, the description and additional equipment of which include the greatest functionality, even make it possible to obtain complex products with asymmetrical contours.
Machining centers that combine several machines, equipped with additional mechanisms, are designed for long-term operation in stressful working conditions. However, they are somewhat more difficult to use due to the more detailed mechanical design. Machining centers whose technical characteristics include a large proportion of functions, respectively, are more expensive. Therefore, buying machining centers with the largest number of functions means saving on the purchase of several machines, which can include one machining center. Machining centers, the description of which includes the function of milling, drilling, reaming, countersinking and boring, will require a significant stock of metal-cutting tools during operation. Keep this in mind if you are considering choosing a machining center for your business.

CNC horizontal machining centers allow countersinking, boring holes, drilling, reaming, threading - and this is not a complete list of possibilities. Auxiliary functions include automatic tool change.
Universal CNC machines are suitable for medium-scale production, also for simple jobs. CNC machines can be equipped with various tooling systems. Universal CNC machines, the technical characteristics of which cover the maximum range of work, are correspondingly more expensive than their simplified counterparts. Keep this in mind when you decide to buy CNC machines. CNC machines, whose description ensures that this model of equipment can process both small parts and large ones - up to 10,000 mm long, can be a great start for expanding production, even if at first you only needed to machine small parts. If you want to buy CNC machines or universal CNC machines, carefully study the features of each model in order to reserve the prospect of expanding production. Universal CNC machines, the description of which involves various options use this equipment, have a degree of protection that complies with the EU.

You can buy universal machines with DRO for use in serial and large-scale production, in warehouses, repair shops. Universal machines with DRO, the description of which consists of more than 20 main components and parts, are universal equipment that is easy to reconfigure.
To control the accuracy in production, coordinate measuring machines can be used, which are designed to measure the parameters of parts, measure orientation or angles. Coordinate measuring machines, whose technical characteristics are highly mobile, are the best replacement for traditional stationary coordinate measuring machines. If you need to buy coordinate measuring machines, choose ergonomic models. Coordinate measuring machines, whose description guarantees the measurement of parts with an internal cavity, significantly reduce the total cost of measurements. Measuring machines can be controlled either manually or automatically - using software. Measuring machines, the technical characteristics of which divide the equipment into groups (mechanical, laser, optical, daylight), support the function of programmed control of the actions of the measuring equipment. If you need to buy measuring machines, make sure that the equipment meets all the requirements of your production. Measuring machines, the description and ease of maintenance of which should be a priority for any buyer, have an easy-to-use modular design.
CNC grinding machines differ from devices having manual control the fact that ensuring the productivity of work on a CNC machine often does not depend on the grinding process itself. It largely depends on the reduction of time spent on metal processing and programmed automatic control of the 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;
- precise 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 a fairly high accuracy of 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 grinding machines CNC, 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-scale individual productions, their use is difficult, since it is quite difficult to readjust these devices, since this will require significant time costs, highly qualified service personnel.
Such difficulties are associated with technological features these grinding machines, for example:
- the existence of leading, grinding grinding wheels in them;
- the presence of special ruling devices that 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 Grinding Machines
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.
In 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.
