Brake systems are crucial elements in the CNC turning machinery realm, and their performance and efficiency can substantially impact the equipment's overall functioning. One prevalent but critical procedure that mechanics routinely carry out on brakes is bleeding. This article illumines the process of bleeding CNC turning brakes.
Unraveling the Worth of CNC Turning
Computer Numerical Control (CNC) turning, an integral part of the manufacturing sector, involves spinning a part while a single-point cutting tool moves parallel to the axis of rotation. It's a favored method amongst manufacturers, partly because of the precision it guarantees, and chiefly because it allows for complex cuts in hard materials under a controlled, automated system.
Understanding Brake Bleeding
Brake bleeding is the process where air bubbles are expelled from the brake fluid of a hydraulic brake. Over time, the brake fluid collects air bubbles, reducing the hydraulic pressure the brake system can apply to stop the machine. When the brake pedal feels spongy or the brakes don't function correctly, it may be time to bleed the brake.
Ensuring Safety First––Accessorizing
Safety comes paramount when dealing with bulky and potentially hazardous machinery. Protect yourself with safety glasses and gloves, dispose of used brake fluid correctly, don't reuse brake fluid, and always perform this procedure in a well-ventilated area.
Procedure for Bleeding CNC Turning Brakes
The actual process of bleeding CNC turning brakes comprises of various steps followed meticulously.
1. Preparation: Gather the necessary tools including a brake bleeder wrench, clear tubing, brake fluid, and a drain container. Also, ensure you have backed up the CNC turning machine data in case the system has to be shut down completely.
2. Access the Bleeder Valve: This valve, usually situated at the rear of the brake, needs to be located. Attach your clear tubing to this valve, leading the other end into the drain container.
3. Pump and Hold: Start the CNC turning machine and allow it to idle. Gradually apply pressure on the brake pedal, simulating the actions of applying the brake.
4. Loosen the Bleeder Valve: While the brake pedal is being held down, slowly loosen the bleeder valve. The brake fluid begins to flow through the clear tubing into the drain container. The fluid flow carries any air bubbles in the system with it.
5. Tighten the Valve and Release Brake: Once the fluid's flow stops, close off the valve, ensuring it＊s firmly closed but not overtightened. Release the brake immediately after.
6. Reverify the Process: Repeat the process until there are no air bubbles in the brake fluid exiting the bleeder valve.
7. Replenishing the Brake Fluid: Keep eye on the brake fluid level during the process, supplement with additional fluid if required.
This routine must be performed for all brakes in the CNC turning machine.
Key Takeaways
Bleeding the brakes is a straightforward procedure that must be carried out routinely to ensure the efficient and smooth running of your CNC turning machine brakes. Despite its apparent simplicity, it's an essential maintenance procedure that could improve the performance and lifespan of your CNC turning machinery.
Remember always to prioritize safety during the process, handling all fluids responsibly and ensuring proper disposal of used fluids. With clear attention to detail, regular maintenance, and a commitment to quality, you'll get the best out of your CNC turning machine and its braking system.
