Achieve Tight Machining Tolerances With These Helpful Tips

CNC End MillSo, you’ve reviewed the drawing with the engineers and designers. You’ve verified the dimensions and double and triple-checked the features. You’ve asked the team if they have any flexibility. You’ve explored every option, but alas that +/-0.0005 tolerance (or tighter sometimes) is correct. Now, you have to make the part. Here are some tips for maintaining tight tolerances.

Calibration

Machine maintenance is critical for the best performance. While CNC mills are designed to have minimal deflection, things move over time. It is a good idea to contact the manufacturer to service and calibrate machines annually. They can use specialized tools like the interferometers and laser calibration systems to ensure machines are in tip-top shape.

Warm-Up

A warmup routine might be standard procedure for any milling operation, but these routines are mostly designed to ensure the lubrication and bearings are warmed up. A high-precision operation should include a more aggressive routine to warm up all the internals. This exercise will minimize any dimensional changes that occur as the machine reaches operating temperature.

Thermal Stabilization

Thermal stabilization is different than warm up. While getting to operating temperature is essential, it is also vital for the environmental temperature to be stable. Shop temperatures might fluctuate throughout the day, or a specific machine might be near a vent, window or sunny spot. All these things can cause the workpiece or the machine to change dimensionally. Don’t forget to stabilize the material’s temperature too. If it is stored outside or in a cold room, it should be allowed to stabilize to an ambient temperature near the machine before starting.

Tooling

The right tooling is a necessity for achieving tight tolerances. Consider using radiused tools for rough cutting to reduce tool wear and allow for faster machining. Then use a sharp, square end tool for finishing. The tool should have the maximum number of flutes allowable. For holes, a reamer has better precision than a bit and leaves a fine polished finish.

Passivation and the Internet of Things

Internet of ThingsThe Internet of Things is an interesting and growing idea in both the home and the industrial workplace. It is essentially the concept of connecting any device that can be turned on and off to the Internet. That’s right – the Internet of Things connects everything from cellphones to table lamps to even parts of items, like the engine of an airplane or the drill on an oil rig, to the ‘net.

In a recent whitepaper from Walter Surface Technologies, inclinations are made that the Internet of Things might even have a connection with industrial shops via the Surfox Smart Passivation Tester, which is a unique that is technique allowing manufacturers to test the passivation of stainless steel prior to preparing items for shipping.

What exactly is passivation? In a nutshell, it is the act of using a light coat of protective material – perhaps a metal oxide, for instance – to create a sturdy shell that protects a stainless steel product against corrosion. Pairing passivation with the Internet of Things could allow machine shops to perform more real-time quality testing to better guarantee an even layer or protection and even guarantee that metals and the equipment that has been coated will hold up over time.

The Internet of Things allows the Surfox tester to obtain tests results wirelessly. It does this by syncing with smartphones and then checking the metals as a technician sweeps the tester over the surface of a coated item. Once the device gets a reading, it then transmits the resulting logs to an online cloud-stored database where the machine shop can then analyze the results of the passivation tests, says MMS Online.

Of course, there are safeguards, as the process doesn’t only rely strictly on a connection to the Internet. If offline, results can still be monitored without a Wi-Fi network via the Surfox app. It is a great process and knowing that products are being consistently treated within the shop before being sent out into the field is a great way for machine shops to maximize their quality and productivity.

It can be a complicated process, but the whitepaper lays out the groundwork and the potential applications quite well, and it is certainly worth a look.

Tolerating Tight Tolerances

managing tight tolerance projects with your cnc lathe

The Benchtop lathe is a mainstay for many machine shops, and it often must implement designs with tight tolerances. Tighter tolerance often translates into higher production costs, so finding the right balance between manufacturing cost control and producing the product as specified can be difficult.

The Meaning of Machining Tolerance

No matter how finely calibrated, no machine produces pieces with perfect dimensions. Sometimes, outside factors, such as temperature changes or varying humidity play a part.

However, even without any environmental influences, perfection is illusory, and certain ranges of variation in dimensions and such must be tolerated. A little wiggle room is necessary. Pieces exceeding permitted tolerances are often unusable. (more…)


Cool Down With the Right Coolant

cool down your cnc mill using the right coolant

Manufacturing with a 3 axis milling machine creates parts and components, and it generates heat. Without the correct coolant, machines break down, and prior to that happening, product quality suffers.

Check the Levels Before Every Job

Familiarize yourself with each machine’s coolant gauge. Most CNC machines have a coolant tank, which sits inside a housing. A floating gauge monitors the amount of coolant in the tank and connects to the machine controls via a cable.
