Successful tapping applications depend on several important factors. These can include axial compensation on CNC machines, internal coolant supply, and special advantages related to self-reversing tapping attachments, according to Mark Johnson, president of Tapmatic Corp., Post Falls, Idaho. “Rigid or synchronized tapping on CNC machines has become an industry standard,” he said. “Even though the synchronization of the machine’s feed advance to the spindle rotation is accurate, there will always be a small discrepancy between the actual pitch of a specific tap and the machine’s synchronized movement.”

Using a completely solid holder means that even a very small discrepancy will cause high axial forces on the flanks of the threads. “This has a negative effect on tap life and thread quality,” said Johnson. “Using a tap holder with a small amount of axial compensation allows the tap to better follow its pitch and this reduces the axial forces for a dramatic improvement in tap life and thread quality.” 

Tapmatic’s SynchroFlex tap holders include a machined flexure that provides a small amount of axial compensation. “The SynchroFlex flexures have a high spring rate, which is important for avoiding axial miscutting,” he said. “If the spring force is too soft, like in the case of traditional tension-compression tap holders with a large amount of axial compensation, axial miscutting can occur. This is especially true when using free-cutting, high-speed taps often recommended for synchronized or rigid tapping cycles. SynchroFlex is designed to provide just the right amount of compensation for synchronized tapping.”

A SynchroFlex II SFT50 performing synchronized tapping with M8 on a CNC lathe with live tooling uses a self-reversing tapping attachment at 2,500 rpm to tap ten M8 holes in 11 seconds. (Provided by Tapmatic)Lubrication is important for tapping in general and especially for roll form tapping. “Using a tap holder with internal coolant capability allows the use of taps with either an axial coolant hole for blind holes, or radial coolant holes for through hole applications,” said Johnson. “This gets the coolant where it is needed for the cutting or forming of the threads. It also greatly helps with clearing chips out of the hole when using cutting taps.”

Tapmatic’s SynchroFlex tap holders all include a balanced, high-pressure internal coolant system. Pressure up to 80 bar or 1,200 psi can be used and because the system is balanced, the coolant pressure does not influence the tap holders axial compensation.
Self-reversing tapping attachments offer special advantages compared to synchronized tapping. “With synchronized tapping, because the machine spindle needs to stop and reverse within a very limited number of revolutions, it is not possible for the machine to maintain the programmed spindle speed. Using a self-reversing tapping attachment allows the machine spindle to turn continuously in one direction at the actual program speed. The result is a shorter cycle time,” said Johnson.
​
For example, in one test using rigid tapping to tap ten M8 holes at 2,500 rpm, cycle time was 18 seconds. Repeating the same test at 4,000 rpm saved just one second. Using a self-reversing tapping attachment at 2,500 rpm to tap the same ten M8 holes took just 11 seconds. “In addition to improving cycle time, using a self-reversing tapping attachment also allows the tap to run at the recommended speed, and this provides longer tap life as well,” said Johnson.

Modern CNC machines have the capability of synchronizing the spindle rotation to match the feed advance for a specific tap pitch. The "Rigid" or synchronized tapping cycle is very accurate, but it is impossible to avoid small discrepancies between the machine synchronization and the actual pitch of the specific tap being used. Using a rigid tap holder means that any deviation at all increases the thrust forces acting on the tap and this dramatically reduces tap life.

At the heart of SynchroFlex® is a precisely machined flexure which provides axial and radial compensation for the unavoidable discrepancy between the machine feed advance and the actual tap pitch. By compensating for this error, the thrust forces acting on the tap are dramatically reduced.The result is the longest possible tap life, 100% improvement or more, and much better quality threads.

Haskel Inc. (Burbank, CA) manufactures a variety of compressed air driven pumps for use in a cross-section of industrial applications. The company experienced quality control issues with the manufacture of its miniaturized models. Burrs are created in the airdrive system's aluminum sleeve, which must meet specification of 16 micro-finish.

To produce the sleeve, which is about "2 long, Haskel machines the part from 13/16" diameter aluminum bar stock. The sleeve is then put on a conventional drilling machine, where an operator drills two series of holes around the sleeve. One series has 1/8" holes, while the other has 3/32" holes.

During the drilling process, burrs are produced along the inside diameter of the sleeve. If these burrs remain, the pump can be damaged. For instance, a spool slides back and forth like a piston with O-rings inside the sleeve to open and close the holes. During this cycling action, a loose burr can cause excessive wear on the O-rings.

After drilling, the sleeve is taken to a workstation where an operator uses ano-burr tool to put an edge break on each one ​he holes. Even after this step, very small burrs still remain lodged inside the sleeve.
​
In the past, Haskel sent the sleeves to an outside vendor where the minute burrs were removed in an entirely manual operation - a costly and time consuming process. After the deburring, the sleeves were then returned to the plant for as- sembly.

A new deburring/finishing system called Flex-Hone@ offers a solution to eliminate small burrs. Manufactured by Brush Research Manufacturing Co., Inc. the system consists of a resilient-based hone with abrasive laminated to the ends of bigh-density nylon fila- ments. At Haskel, the 1 mm diameter, 180-grit silicon carbide hone is placed in a standard drill chuck. The system has resulted in a smoother, more efficient operation. After the preliminary deburring step, the sleeves are taken to the deburring station.

At this point, the operator places a pan of kerosene beneath the hone and loads the pan with the sleeves, which become lubricated. At the same time, the drill motor is activated, rotating the hone at about 100 pm. The operator then lifts a sleeve to the revolving hone and makes five or six passes. Inside the sleeve, a spring-like action causes the tool to knock out any burrs remaining in the holes.The parts are then ready for burnishing.

With an annual production of 10,000 - 20,000 sleeves, the company uses two or three hones per standardorder of2,500 parts. For Haskel, the Flex-Hone® tool provides better quality control and cost savings, paying back the cost of the system many times over.
The company now saves 40% of the total cost of producing the part as opposed to jobbing the work out. ​

In precision machining, where every micron counts and every vibration matters, the search for the perfect balance between precision and performance has been ongoing for decades.

Enter the B-Safe X System from Balance Systems, a true game-changer in machine tool monitoring. This innovative solution offers manufacturers a powerful tool to achieve the highest levels of precision and efficiency, reducing downtime, minimizing tool wear, and ultimately elevating the quality of your machining operations.

Five-axis machining has built its reputation in the metal manufacturing world through the many advanced machining strategies that are impossible without the additional rotational axes that set it apart.

​However, many manufacturers have found great benefits in 3+2-axis manufacturing techniques, using the rotational axes to reduce setup time. This approach can provide a firm foundation for highly automated machine cells such as the ones I found at Clippard Manufacturing, a Cincinnati-based valve manufacturer and machine shop.
​

Clippard began in the 1930s as a manufacturer of radio parts. Its early claim to fame came during World War II, when it manufactured coils for the Allies’ radio-based proximity fuse — one of the most successful weapon technologies developed for the war. Over subsequent decades, the company pivoted to pneumatic valves for various industries, especially the medical industry. More recently, the company has also begun working as a contract manufacturer of medical parts, putting its experience meeting the exacting standards of the medical industry to further use.

The company’s first foray into heavy automation was in its fleet of 20 Swiss-type lathes, which found success working lights-out. Using this success, Manufacturing Engineer Alex Werdman convinced the company to invest in a five-axis Haas UMC 500 SS with a 16-station pallet changer to perform work that had been done on three-axis mills. The company made this investment with the intention of developing lights-out processes for the machine cell, but getting to that point meant investing in more than just the machine tool.

One of the major draws of a five-axis machine was the ability to dramatically reduce setup time by machining multiple faces of parts in a single setup. According to Werdman, the move to the five-axis Haas made the jump to high-mix medical work much easier. “Being able to reach more faces of the part reduced the setup time for secondary operations by a lot,” he says. “Jobs that took 45 minutes per part on a three-axis were down to 27 minutes.” CNC Programmer Kyle Shearer agrees, saying, “I might touch a part 17 times before and only four times now.” However, this strategy relied on workholding that provided the cutting tool as much access to the part’s faces as possible.

At first, Clippard considered using dovetails, but after a conversation with Jergens representatives and distributors, the company opted for vises with modular jaws. “We thought we would have to use dovetails,” Werdman says, “but the vise has enough grip force and clearance to meet our needs.”
​

​And did this work pay off? “The Haas proved that five-axis machines were worth it,” Werdman says. “We could get 50 hours a month on the three-axis mills, and with fiveaxis we get 200-300 hours.”

The success of the Haas spurred Clippard to invest further in five-axis machining with a Matsuura MAM72-35V, intended to both increase the volume of parts the company could produce lights-out and improve the precision of its fiveaxis machining.

The Matsuura came standard with a 32-station pallet changer in a condensed footprint, dramatically increasing the capacity for lights-out machining. Like the Haas, it regularly puts in over 200 hours of machining time, mostly performing 3+2-axis machining. It can also pursue more aggressive machining strategies while maintaining the finish needed, as it can maintain a tolerance of ±0.0005 inches.
​
Despite being one of the major benefits of five-axis machining, this kind of dramatic increase in capacity and production speed is often overlooked by machine shops. Not all fiveaxis machines produce near-net shapes or large contours, and shops like Clippard have found great success thanks to careful consideration of the machine cell as a whole.

​“The people in charge needed convincing,” Shearer says, “but once they saw how much more we could get done and how quickly we could do it, they were on board.”
