High Score Questions about CNC machining centers and tool magazines

It's been a long time since I left school, so I can only talk about it in layman's terms, forgive me!

Machining center tool magazine, I take the commonly used boring and milling horizontal machining center as an example, generally there are tool magazine motors, knife cup chains, transmission sprockets, tool change manipulators, manipulator driven hydraulic cylinders (or cylinders), protective plate gold, etc., no matter what tool magazine, the key is the tool magazine capacity and tool change time. The Lijia tool changer is comparatively simpler.

Machining centers are divided into turning machining centers, boring and milling machining centers, turning and milling compound centers, and others such as grinding machining centers, CNC stamping compound centers and so on. The key to identifying its method is to look at the processing method and processing principle of the machine tool.

Compared with the horizontal machining center and the vertical type, from the machine tool manufacturing, the bed parts are larger, the stroke is generally longer, usually the B axis (the worktable can be rotated), the power of the motor, the capacity of the tool magazine is also larger, (32 less points, hundreds of more points), generally choose a double workbench (exchange the workbench to improve production efficiency, while processing, while changing the workpiece), the control electrical components used are also more, the numerical control system is due to the number of control axes, and the machining accuracy is required to be high. Therefore, the mid-to-high-end system is generally used, to put it bluntly, the larger the bed, the more expensive it is. (Of course, it must be compared under equal conditions).In terms of structural characteristics, the main axis of the large aspect vertical addition is perpendicular to the horizontal, and the horizontal addition is parallel to the horizontal, and there are too many specifics, I don't know how to talk about it.

Hope you find the above helpful!

1. Adjust the tool magazine to the No. 1 tool position;

2. MDI uses M33 for local posture;

3. Rearrange the parameters of the tool position in the parameters. From zero to the last tool position in the magazine.

Types of magazines.

The tool magazine is used to store the tools, and it is one of the main components in the automatic tool changer. According to the number of knives in the knife inventory and the way of taking the knives, the tool magazine can be designed into different types.

1) Linear tool magazine. The knives are arranged in a straight line in the tool magazine, the structure is simple, and the number of tools stored is limited (generally 8-12), which is rarely used;

2) Disc tool magazine. The number of knives in stock is as small as 6-8, and as much as 50-60, there are various forms;

3) Chain tool magazine. Chain tool magazine is the most commonly used form, commonly used are single row chain tool magazine and extended chain tool magazine;

4) Other tool magazines. The lattice box tool magazine has a large capacity of the tool trace virtual library.

Hello, if there is an inconsistency between the tool number in the tool magazine of the machining center and the program, it may be due to the following reasons:1The tool number is not set or entered correctly.

2.The tool in the tool library has been changed or relocated, but the tool number in the program has not been updated accordingly. Here's how to fix it:

1.Confirm whether the tool number is correct: check whether the tool source number used in the program is consistent with the actual tool number, if the late cracking and burial fruit are inconsistent, you need to modify or reset the tool number.

2.Update the tool number in the program: If the tool in the tool magazine has been changed or the position has been changed, you need to update the tool number in the program to ensure that the tool number used in the program is the same as the actual tool number.

If the above methods cannot solve the problem, it is recommended to contact the manufacturer or maintenance personnel of the processing center for maintenance.

The loading method of the CNC machining center tool magazine is to put the tool on the spindle and run the T6M06 operation program in the manual input mode to complete the tool loading. In addition, it should be noted that there is no knife on the spindle before applying the knife.

The comprehensive processing capacity of the CNC machining center is strong, the workpiece can complete more processing content after a clamping, the processing accuracy is higher, and the batch workpiece of medium processing difficulty is 5 10 times more efficient.

In particular, it can complete many processes that cannot be completed by ordinary equipment, and is more suitable for single-piece processing with complex shapes and high precision requirements or small, medium and medium-sized batch multi-variety production. It combines the functions of milling, boring, drilling, tapping and threading on one machine, making it have a variety of process means.

The feed processing route of the CNC lathe refers to the path through which the turning tool starts to move from the tool setting point to the return point and ends the machining program, including the path of cutting and the non-cutting idle stroke path such as the cutter cutting in and out.

For example, if you want to put a knife in the No. 5 position of the tool magazine, first empty the spindle, and then in MDI mode, run T5 M06, after running, put the knife on the spindle, and then under MDI, run T6 M06, this is a fighting hat type tool magazine.

First enter the program M06T** in MDI mode, press the cycle to start, T** refers to the tool position number, the program is executed to ensure that there is no knife on the spindle, and then press the handwheel or manual mode on the control panel, and then press the hydraulic button on the spindle do not move, put the knife you need on the spindle, and finally release the hydraulic button, so that the knife is placed on the spindle. Repeat the start, enter an empty tool position number in MDI mode, press the hydraulic button, put the tool on the spindle, and complete the second tool, and then go down to install all the tools you need, and complete your tool loading purpose on the machining center. I hope my answer is helpful to you.

Dechert tool magazine does not know whether the second reference point of your bed system [the tool change point of the machine tool] is determined by G28 or G30, if it is G30. Programmable G9i G30 Z0; Spindle tool change point t2 m6; Change the No. 2 knife to the spindle if it is G28. Dechert's swash plate tool magazine can be changed from G30 to G28 in the upper section.

One. Disc tool magazine.

The most common form is the disc tool magazine, where one tool can be placed in each tool holder. The disc tool changer is compact and simple. It is also more convenient to take the knife, so it can be used in a wide range of applications. Due to the limited disc size, the capacity of the tool magazine is small. (usually 15-30 knives).

Two-chain knives. The structure of the chain tool magazine is more flexible, the number of tools stored is also larger, and the action of selecting and taking tools is relatively simple. When the chain is long, the number of supporting sprockets can be increased. The chain is folded and wound to improve the space utilization.

The ring chain is equipped with a number of tool holders, the holes of the tool holder are loaded with various tools, and the chain is driven by sprockets. The linked tool changer is suitable for the occasion with a large tool magazine capacity and is a multi-axial tool pick-up.

3. Fixed lattice box tool magazine. The cutter is divided into a straight line arrangement, and the tool selection movement is completed by the tool taking manipulator that moves in multiple directions vertically and horizontally, and the selected tool is sent to the fixed changing position tool holder, and the tool is exchanged because of the tool changing manipulator. Due to the intensive demining of knives.

Therefore, the space utilization rate is high and the tool magazine capacity is large.

In addition to the three magazines mentioned above. There are also linear tool changers and multi-disc tool changers.

Types of magazines.

The tool magazine is used to store the tools, and it is one of the main components in the automatic tool changer. Depending on the number of tools in the tool stock and the way of taking the tool, the tool magazine can be designed into different types.

1) Linear tool magazine. The knives are arranged in a straight line in the tool magazine, the structure is simple, and the number of tools stored is limited (generally 8-12), which is rarely used;

2) Disc tool magazine. The number of knives in stock is as small as 6-8, and as much as 50-60, there are various forms;

The cutter is arranged radially, occupies a large space, and is generally placed at the upper end of the machine tool column.

The cutter is arranged axially, often placed on the side of the spindle, and the axis line of the tool magazine can be placed vertically or horizontally, which is more used.

The cutter is arranged in the shape of an umbrella, and is mostly placed obliquely at the upper end of the column.

In order to further expand the storage capacity, some machine tools use multi-turn distributed tool magazines, multi-layer disc tool magazines and multi-row disc tool magazines. The multi-row disc tool magazine has 4 knives per row, which can be replaced in the whole row. The latter three types of tool changers are used less often.

3) Chain tool magazine. Chain tool magazine is the most commonly used form, commonly used are single row chain tool magazine and extended chain tool magazine;

4) Other tool magazines. Lattice box tool magazine.

There are many forms of tool magazine in Dechert tool magazine machining center, mainly including Dechert hat tool magazine, Dechert chain tool magazine, Dechert tool head type, and warehouse type and so on.

The change to the form is also varied according to the change of the tool magazine form. There are turret type, tool change arm type, spindle direct knife type, and manipulator tool change type. Dechert knife library.

Hat, disc, turret.

The machining center is an automatic machine tool, and whether the machining center has a tool magazine or not, it has nothing to do with the operation of the system. A machining center without a tool magazine cannot change tools automatically. Generally, the machining center for making molds will not be equipped with a tool magazine.

As for the operation, the machine tool with a tool magazine refers to the automatic tool change instruction that can be programmed in the program, and the machine tool can be changed automatically. Machining centers without a tool magazine are suitable for parts where the number of tools is small and manual tool change is possible. The machining center without a tool magazine is similar to the CNC milling machine, but some CNC milling machines cannot carry out XYZ three-axis linkage machining.

Machining center is a kind of mechanical equipment can be used to clamp the workpiece in a multi-type processing, the workpiece can complete the processing of a variety of processes on more than two surfaces after a clamping on the machining center, and there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.

The difference between a machining center and a CNC milling machine is whether it has an automatic tool change mechanism.

Criteria for judging machining centers: 1Usage:

Machining of box parts and complex curved parts. 2.Features:

Milling, boring, drilling, tapping, etc. Because it has an automatic tool change function, the workpiece can be clamped at one time, and all machining operations on all sides of the workpiece can be completed automatically or close to completion. It has nothing to do with the existence, form and location of the "library", the purpose of the "library" is to provide basic conditions for automatic tool change, and the automatic tool change is to achieve a clamping and complete each processing process.

The machining center can be washed and washed, and the machine can be loaded with many tools and has powerful functions. The difference between a machining center and a CNC milling machine is whether it has an automatic tool change mechanism.

The characteristics of the machining center are automatic tool change, and the tool "library" provides conditions for automatic tool change, and the common tool magazine forms are disc type, hat type, chain type, umbrella type, and handle type. The form of "library" is diverse, foreign advanced machine tools with more than 5 axes, and even more than 8 axes, in a unique form, which realizes tool change, one tool for multiple purposes, and multiple tools by installing spare or ready-to-use tools on the main and auxiliary axes at the same time, reducing the stroke of the off-site tool and the process of multiple clamping, and making highly reasonable and effective use of the space in the lathe to ensure precision and efficient processing efficiency.
