CNC Machining Centers

Almost every manufacturing company has CNC equipment there are many types and brands like Makino cnc machining centers, Toyosk, Okuma & Howa and many others. All brands of course have many advantages and disadvantages depending on what products will be in the process. Example for milling process I prefer okuma & howa because they are special in milling processes and machines are very robust and proven reliability. The main function of the CNC machining center is that it reduces manual labor and also save time. Because the machine is set by the computer, the various calculations involved in the job taken care of as well. Processes that can be done include CNC boring milling, drilling and tapping. CNC machining center to do all the work themselves, with perfect precision. To run a CNC machine programmers need to be in need, because the movement of the machine had been instructed via the computer. Thus not everyone can run a CNC machine needs to learn, a lot of places to study for cnc programming even in school - the school have been taught but the basic program. To further explore the need to have special training. In the CNC machining centers have 3 movement you should know that the first is the Circular Motion is a motion in a circle this is usually to make a seal holes in the second cylinder Straight Line Motion allows the machine to move in a straight line is usually to move the process of milling and then the third This movement also called movement position because this movement without cutting, bias to avoid crashing into material tool when the tool change (ATC), so need to move position.

Components CNC Vertical Milling Machine

Milling machine is divided there are 2 types of Vertical and Horizontal orientation of the term refers to the cutting spindle. That the mean vertical position of the machine spindle and cutting direction vertical and horizontal machinery is horizontal spindle position (horizontal cutting direction). Here I will discuss CNC Vertical milling machine. I will discuss the critical components on CNC Vertical Milling Machine.

- Table machine. Vertical milling machine can move with 2 axis X and axis Y. for each axis is equipped with a servo motor which in control through the amplifier with a command from the computer with a precision movement. Also equipped with a ballscrew, bearings and linear guide. Usually use oil for lubrication, this is very important because to maintain the smoothness of movement and ballscrew will be durable. This table you can move it manually by turning the pulse generator.
- Spindle machine. This section is a spindle house, this is what set the spindle rotation axis Z. cutting moves this spindle motor is also in motion by using a timing belt as the transmission.
- Control Panel. Control Panel contains a collection of many buttons are in front of the machine that serves to give commands such as rotating spindle, to change parameters, and other programs.
- Monitor. The monitor will display the position coordinates, position the machine, parameters, diagnostics and others.
- Magazine tool. Magazine tool is to place the standby tool to be used in a single machining operation. Because in one program usually use some kind of tool. Tool exchange is performed automatically called ATC (Automatic Tool Change).
- Coolant. Coolant used for cooling at the cutting progresses, each machine is equipped with the system.

That's the critical components on CNC Vertical Milling Machine.

Knowing the Parts of Plasma CNC Machine

Image www.indiamart.com

Plasma CNC machine is known as a tool which can cut a piece of material in a unique manner, i.e. using plasma. It is controlled by a computer program which allows the work to be done in much accurate way. To figure out how the machine is able to conduct the task well, check the features below.

Plasma Cutter

The first part of plasma CNC machine is the plasma cutter. The tip of the torch works similarly to those of hand held cutting machines. The nozzle of the cutter functions to direct cutting gas, shielding gas, electrode, and the plasma. Although the plasma cutter should manage to function in three dimensions, most devices work in two dimensions (X and Y).

Table Plasma CNC Machine

The table is a surface where a piece of material will be put on for cutting. The table is commonly made of steel with a grate that functions to hold the material. Most types of tables are modular because there will be a regular replacement for them.

Armature

This part of plasma CNC machine is made of two arms that move concurrently. Both arms are moved by a motor. The input of the CNC, however, can move the tip along with any shape programmed. This enables the cutter to carve various kinds of patterns, from the simplest lines to much complicated design.

Program

The computer of the machine consists of a microprocessor, data storage and memory. This is just as similar as those found in any basic computer. However, there is a CNC program that functions to determine the shapes of cutting.

CNC program is also called as the design. The design is scanned to the computer then with a help of specific language program, it is changed into something that can be fed to the CNC program.

By knowing the elements of plasma CNC machine, the user or operator will have a sharpened knowledge about the machine so that he can better use the device.

Fanuc Pulse Coder Alarm - Solve Problems

Before you fix the alarm pulse coder must know first what the cause of the alarm pulse coder? That caused the alarm pulse coder is the first error pulse coder itself. If that is you have to change. Cable, check the condition of the cable with multitester whether there is a break. Drive (SVM) faulty. Parameter settings are not right but this is rare, and an excessive load on the axis.

Fanuc Pulse Coder Alarm
For a detailed explanation for the alarm pulse coder on a machine CNC machining. Check the cable connections if contaminated with coolant. It often happens coolant into the connector due to telescopic a leak. Spray with a spray gun for cleaning the coolant air. Also check the pin is in the correct position. If all alarms have been checked still replace it with a new pulse coder.

If still alarm also may drive / SVM trouble. Replace drive / SVM you. At the time wanted to change the pulse coder must be careful not the hammer, then will cause damage. To find the problem that happens you can help the operator. Ask if the alarm came when the axis moves? What is the current axis position of silence? What is the specific coordinates? If the alarm in this position usually your cable problems.

To repair the zero pulse coder position is changed then you must reset the settings. In order for the zero position is not far away with the old one better at the time of going improvement Condition zero position for when the repair is completed you can simply reset the settings without looking back to the zero position.

3 Axis CNC Machine vs 2.5 Axis CNC Machine

Considering the number of axes being used, there are several types of CNC machines. One of them is 3 Axis CNC machine. As the name suggests, this machine has three axes. What makes you surprise is perhaps the fact that the number of axes is as many as those in a 2.5 axis machine. Indeed, a 2.5 axis machine also has three moving axes yet the difference is that the third axis cannot move together with the two.

3D Full Feature

In another definition, a 3 axis CNC machine commonly has a full feature of 3D while 2.5D machine is a kind of machine that uses 2D drawing for 3D material. In 2.5D, you just simply put the information about thickness in the software so that the machine can cut the material in 3D manner. So to say, with 2.5 axis CNC machine you are only capable of viewing the angles from two points while with 3 axis machine, one more angle can be accessed.

Concurrent Process 3 axis CNC machine

Designing and cutting happen simultaneously in a 3 axis CNC machine as it works on X, Y, and Z axes. The tip of the cutter will follow the path of 3D curves which have been determined in the program. This enables the machine to make a fine cut of a complicated pattern on a piece of material.

On the other hand, a 2.5 D machine can produce similar items but in much different way, like a v-carving method. This method allows the machine to create a 3D result yet the designing is supposed to be done in 2.5D. The best news is 2.5D designs have relatively lower price than 3Ds. Therefore, this type of machine can be chosen in case of you are on a budget.

Choosing which type of CNC machine suits you depends on the urgency and the budget available. If you think that you can manage with 2D drawing and v-carving method, your plan to buy a 3 axis CNC machine can be postponed.

Introduction CNC Machine

The first NC machine was first invented in the 40s and 50s, by modifying the ordinary machine tools. In this case ordinary machine tools added to the motor that will move the controller to follow the points are inserted into the system by recording paper. Machine combination of servo motor and mechanical system is immediately replaced with analog and then digital computers, creating modern tooling machines called CNC (computer numerical control) that were later have revolutionized the design process.
In general, how to operate a CNC machine by entering the numeric tail command buttons are available on the instrument panel on each machine. Each type of CNC machine has its own characteristics in accordance with the factory that makes the machine. But characteristically there are 2 ways an absolute system is a starting point cut as a reference and is valid during the process. And the system incremental in this system the starting point placement which is used as a reference is always on the move in accordance with the actual point of the last stated.

CNC machine tools equipped with cutting tools that can make precise work piece and can perform numerically directed interpolation (based on numbers). CNC operating system parameters can be changed through software programs (software load program) is appropriate. The precision CNC machine is more accurate to thousandth millimeter accuracy, because the uses of ball screw on each axis of transportation.

In CNC machining usually use 3 axis for movement of X, Y, Z, but for generally 2 axis lathe X and Y. for a new lathe to rotate the turret now using servo motors do not like that used by the system hydraulic. You can see in the new TAKISAWA lathe, while the lathe is still using hydraulic Moriseiki. To use hydraulic way turret sensor number setting tool somewhat difficult because of using 2 switches phase A and phase B, which can be read more than 4 tool. For the turret servo motor is relatively easy to use, just specify the tool 1 (first).
