What is 5-axis machining? What are the advantages of having multiple axes?

Explanation of the directions and movements of each axis, as well as the advantages and disadvantages of 5-axis machining!

In cutting processes using machining centers and multi-tasking machines, various parts such as the spindle, turret, and tool axis move and rotate during machining. Each of these has a different direction of movement, referred to as movement axes, and they are distinguished by what moves in which direction, such as X-axis, Y-axis, and Z-axis. Traditionally, machining was mainly done using three axes: up and down, left and right, and front and back. In recent years, there has been a demand for machining more complex shapes and reducing installation and processing time, leading to an increase in the use of multi-axis machining machines, starting with 5-axis machining that includes three linear axes and two rotational axes, B-axis and C-axis. [Contents] ■ What is an "axis"? ■ Directions and movements of each axis ■ Advantages of 5-axis machining ■ Disadvantages of 5-axis machining ■ Conclusion *For detailed content of the column, please refer to the related links.

The foundation of manufacturing! What are ISO standards and JIS? What are the differences?

I will explain about "ISO," "IEC," "ITU," and "JIS" in a column format!

In manufacturing, there are parts that can be created freely and parts that should be made according to rules. For example, electronic products like televisions and refrigerators come in various designs and functions depending on the manufacturer, but while there are several types of plug shapes, they are made to a certain degree of standardization. This is because they are made according to rules, which are established not only for shape but also for various aspects such as quality and safety.

Let's reduce man-hours! An explanation of peripheral devices for machine tools.

Here is an example of peripheral equipment for NC lathes and multi-tasking machines presented in a column format!

Peripheral devices in the case of machine tools refer to those that are connected to or installed around the machine to facilitate or make a series of work processes smoother and more convenient. Even if the machining itself is performed by a high-performance machine that can complete everything with one unit, there are still many instances where human hands are needed for the preparation and processing before and after, and there are tasks that can be cumbersome or time-consuming. Peripheral devices come in various sizes, from large to small, and have a wide range of applications. Here, we introduce an example of peripheral devices used with NC lathes and multi-tasking machines. [Contents] ■ What are peripheral devices ■ Devices that assist in the supply and discharge of workpieces ■ Devices that keep cutting oil clean ■ Others ■ Conclusion *For detailed content of the column, please refer to the related links.

What are cutting conditions? How should they be determined?

Explanation of "Content and Method of Cutting Conditions" and "Application of Cutting Conditions"!

To perform machining, machine tools need to specify values such as cutting speed, rotation speed, feed rate, and depth of cut, which are referred to as cutting conditions (or machining conditions). The appropriate values for cutting conditions vary depending on the material of the workpiece and the cutting tool (tool, tool) as well as the shape to be machined, so they must be changed each time the material changes. If the cutting conditions are not appropriate, various disadvantages can occur, such as poor machining accuracy, longer machining time, and chipping or shortening the lifespan of the cutting tool.

How big is Nakamura's machine?

Things as large as a refrigerator or even factories can be completely buried! Here’s an example.

The size of machine tools varies depending on the type, processing method, and the size of the items to be processed. For simple general-purpose machines, there are ones as small as a refrigerator, while fully automated machines that utilize many peripheral devices can be large enough to fill an entire factory. Nakamura's machines are CNC lathes and multi-tasking machines designed for small to medium-sized parts, but just how big are they? I would like to introduce an example.

Explanation of coordinate calculation in the tapered section.

A detailed explanation of coordinate calculations in the tapered section in column format!

A taper refers to a shape that narrows like a cone, and it is a common shape seen in machined parts. At first glance, it may seem that the shape is simply a straight line cut at an angle, without any complicated coordinate calculations. However, in actual drawings, it is not that simple. Often, one of the coordinates for the starting or ending position of the taper can be easily read from the drawing, but the other coordinate needs to be calculated based on the information provided in the drawing. [Contents] ■ What is a taper? ■ Trigonometric functions are essential for coordinate calculations ■ Let's calculate using the drawing! ■ More calculations are needed for actual machining ■ Summary *For detailed content of the column, please refer to the related links.

The benefits of automating machine tools! How to improve the detachment from machines?

Introducing the benefits brought to the workplace, such as factories, and what kinds of tasks can actually be automated!

General-purpose lathes and milling machines, which require manual operation during processing, are used in many workplaces. However, it is difficult to achieve precise machining of the same item, making them unsuitable for mass production, and they also require skilled operators, which presents certain disadvantages. As a result, in recent years, there has been progress in the development of "automation" technologies for various tasks using machine tools. In this article, we will introduce the benefits that the automation of machine tools brings to factories and other workplaces, as well as what types of tasks can actually be automated. [Contents] ■ What is automation of machine tools ■ Background of the growing attention to automation ■ Advantages and disadvantages of automation ■ Examples of processes that can actually be automated ■ Automation of multi-tasking machines ■ Conclusion *For detailed content of the column, please refer to the related links.

Know-how for reducing cycle time in NC lathes!

An explanation of the key points for time reduction that manufacturer engineers actually implement!

NC lathes can automatically cut workpieces by setting the position information of the cutting edge and directing the movement path of the tool with an NC program. Once the program is created, it can repeatedly perform high-precision machining. At this time, the cycle time per product is determined by the created NC program, but it can be shortened by reviewing and optimizing this program once again. In this article, we will explain the key points for time reduction that manufacturer engineers actually implement.

Vibratory cutting

Long cutting chips are a cause of defects! Nakamura's "vibratory cutting" solves chip problems!

"Some chips cannot be separated even with chip breakers or high-pressure coolant." "Are you troubled by issues such as 'high electricity costs' or 'need for installation space'?" "Swing Cutting" separates chips by creating a non-cutting motion. It vibrates the tool through servo control to finely break down the chips. It can be easily executed with G-code commands, resolving chip-related troubles. Please feel free to contact us when needed. 【Features】 ■ Prevents chip entanglement ■ Improves chip discharge ■ Uses servo learning oscillation function (FANUC) ■ Easily executed with G-code commands only *For more details, please refer to the PDF document or feel free to contact us.
