2024年9月8日 · M04 [spindle on, counterclockwise] The M04 code turns the spindle on in a counterclockwise direction at a set speed. Just like M03, the set speed is the value used with the most recent S code.

2024年9月8日 · What does a M04 CNC code do? The M04 code turns the CNC spindle on in a counterclockwise direction. On a CNC mill, M04 is used with left hand tools. This is far less often used compared to the M03 (clockwise) command. The M04 is often programmed together with a spindle speed using the S code such as S2500 M03.

2024年12月9日 · Whether you are new to CNC programming or an experienced machinist, understanding the M04 code is essential. This guide will explain everything you need to know about this unit mode command—what it is, when to use it, and why it matters.

2021年12月24日 · 先学M03/M04/M05，这三个M代码是最常用的M类辅助代码，这三个代码是决定卡盘运转方向的代码，决定刀具能不能顺利将多余材料剔除的一个关键因素。 M03/M3 主轴正转（从尾座向卡盘方向看，是逆时针方向旋转） M04/M4 主轴反转（从尾座向卡盘方向看，是顺时针方向旋转） M05/M5 主轴停止（卡盘静止不动） 例如：上次的手柄图程序，没看的可关注去主页找G02/G03教程. N10 G1 X 0. Z 0. F0.3. 刀具一般分焊接刀（自制用45#钢做刀体，合金刀粒做 …

For CNC machines equipped with a remote activated spindle, the M04 M-Command will activate the spindle in the counter clock-wise direction, also known as Spindle Reverse. For CNC machines with a pulse width modulated (PWM) spindle, an additional parameter will set the speed, typically calculated in RPM.

2023年7月4日 · M04指令用于控制数控机床中的主轴旋转，其功能是将主轴以指定的速度逆时针方向旋转。 通过M04指令，可以实现各种需要逆时针旋转主轴的加工操作，如螺纹加工、倒角等。 M04指令的应用场景： 螺纹加工：在数控机床的螺纹加工中，通常需要逆时针旋转主轴。 通过使用M04指令，可以精确控制主轴的旋转方向和速度，实现高精度的螺纹加工。 倒角：倒角是一种常见的加工操作，通过使用M04指令，可以控制主轴逆时针旋转，使刀具沿工件边缘进行倒角加 …

M03 can be called forward rotation and M04 can be called reverse rotation. Most machines today are tooled for operating exclusively in the M03 spindle direction. Let's look as why it may be more useful to machine parts using the M04 direction. Selecting the M04 command allows you to utilize left hand turret tooling.

2024年3月23日 · Control spindle direction effectively with G-Codes M03 (clockwise), M04 (counterclockwise), and M05 (stop). Learn usage and examples now!

最基本的 m 代码包括 m03/m04（表示主轴顺时针或逆时针旋转）、m08/m09（表示冷却液开/关）和 m30（表示程序结束）。 M 代码如何在 CNC 机床中发挥作用 逐步解释 M 代码的执行。

To start the spindle turning counterclockwise at the currently programmed speed, program: M04. The speed is programmed by the S word. To stop the spindle from turning, program: M05. It’s okay to use M03 or M04 if the spindle speed is set to 0; if …
