Coolant

The role of coolant in CNC milling machine is vital. It improves tool life and ensures smooth machining of the work. The different coolant used in CNC milling includes Mist Coolant, Flood Coolant, Cool Air Gun or Air Blast coolant and Dust Collector. Actually, the dust collector is not a coolant but it creates the initial condition for the coolant to work. It collects the chips and clears the surface. Mist coolant is used where the machine is not in a closure and requires pressure. For the closed conditionof the machine flooding coolant is better.

Way Oiler

Like any moving engine or machine CNC milling also needs lubrication. The guideways need lubrication to allow the smooth motion over the table. The leadscrew is needed to be lubricated as it is getting engaged with gears and motors and also handing heavy loads. In a CNC machine, oilers are generally automated. But it can be done manually too. Automated oilers are good as they ensure timely lubrication.

Powered Drawbar

Drawbars are good if you need to change your tool frequently. If automatic tool changer is used then drawbars are required. Capture and release of the tool holders from the spindle can be done by the means of powered drawbars. Drawbars include Impact wrenches, Pull Stud and Tormach TTS Style. With powered drawbars, you don’t need an operator each time when you want to loosen the drawbar. It reduces the time required by half.

Enclosure

Enclosures create a cover for the machine. A milling machine is always cutting and throwing cheaps. It can be very messy. So an enclosure comes in very handy and the chips or the chips mixed with coolant keeps inside and the production floor remains clean.

4th Axis

As the name implies it gives another movement in a direction different from the direction of X, Y and Z. It is required in many cases. With this, the operator can hold extra parts on the table and can do some extra work on the workpiece.

 According to the functionality, CNC millings can be small or large. And also according to the position of the spindle the CNC milling can be divided into two classes. Vertical and Horizontal milling machines. In vertical milling the tool axis is vertical and in horizontal milling, the tool axis is horizontal to the WP. In horizontal milling, you can do the up milling and down milling. We will discuss the different cutting processes of milling machines in a different article. Hope you have got a good idea about the CNC Milling Machine Parts.
