Minimizing tool wear is a crucial aspect of machining, especially when using metal cutting inserts. Tool wear not only affects the quality of the finished product but also carbide inserts for steel impacts production efficiency and costs. Here are several strategies to help minimize tool wear while utilizing metal cutting inserts:

1. Select the Right Insert Material: Choosing the appropriate material for your cutting inserts is vital. Materials like carbide, ceramic, and cermet each have specific properties suited for different applications. Carbide inserts, for instance, are excellent for high-speed machining, while ceramic inserts can be beneficial for hard materials.

2. Optimize Cutting Speed: The cutting speed should be tailored to the material being machined. A speed that is too high can accelerate tool wear due to excessive heat generated. On the other hand, too low a speed may cause build-up edge. Finding the optimal speed through trial and error or manufacturer recommendations can significantly reduce wear.

3. Control Cutting Depth and Feed Rate: The cutting depth and feed rate also play a crucial role in tool wear. A smaller cutting depth can reduce the load on the tool, thereby minimizing wear. Similarly, adjusting the feed rate can help distribute the heat more evenly and avoid rapid deterioration of the insert.

4. Use Proper SCGT Insert Cooling Techniques: Implementing effective cooling methods, such as flood cooling, mist cooling, or air cooling, helps to dissipate heat and reduce friction. This can significantly prolong the lifespan of metal cutting inserts. The proper coolant type also matters; water-soluble coolants can be effective for certain applications.

5. Regular Tool Inspection and Maintenance: Routine inspection of the cutting inserts allows for early detection of wear patterns. Regular maintenance, including cleaning and replacing worn inserts, ensures consistent cutting performance. It's essential to monitor tool geometry, as changes can lead to increased wear.

6. Experiment with Tool Geometry: The design of the cutting insert, including its shape, angle, and number of cutting edges, can affect wear rates. Using inserts with optimized geometry for specific materials can enhance cutting performance and reduce tool wear.

7. Minimize Vibrations: Vibration during machining can contribute to premature tool wear. Ensuring proper tool setup, using rigid fixtures, and adjusting machining parameters can help minimize vibrations, leading to less wear on inserts.

8. Utilize Advanced Coatings: Coated inserts, such as those with titanium nitride (TiN) or titanium carbide (TiC), can increase tool life by providing additional hardness and reducing friction. These coatings can be particularly helpful when machining difficult materials.

By strategically implementing these practices, manufacturers can significantly minimize tool wear on metal cutting inserts. Not only does this lead to longer insert life, but it also improves machining efficiency, product quality, and ultimately, profitability.

When it comes to machining metals, achieving a superior surface finish is often a primary goal. The choice of cutting tools can significantly influence the final outcome of a machined part, and one of the essential components in this process is the metal cutting insert. These small, Tungsten Carbide Inserts replaceable tips are designed to fit into cutting tool holders and play a crucial role in determining the quality of the surface finish.

Firstly, metal Cutting Inserts are manufactured from highly durable materials, often carbide or cermet, which enable them to withstand high temperatures and pressures during the cutting process. The quality and hardness of the insert contribute directly to its performance, ensuring a consistent cut and reducing the chances of tool wear. A well-maintained insert can produce a smoother finish by maintaining sharp cutting edges throughout the machining operation.

Secondly, the design and geometry of the Cutting Inserts have a profound effect on surface finish. Inserts come in various shapes and sizes, each tailored for specific cutting applications. The rake angle, clearance angle, and edge preparation all influence how the insert interacts with the material being cut. A positive rake angle can facilitate easier cutting, resulting in less friction and heat generation, which contributes to a better surface finish.

Another critical factor is the coating applied to the Cutting Inserts. Coatings such as titanium nitride (TiN) or aluminum oxide (Al2O3) can enhance lubricity and reduce wear, allowing for smoother cuts. These coatings also protect the inserts from oxidation and other chemical reactions that may occur during machining, thereby prolonging their life and effectiveness. When inserts operate at optimal performance levels, they produce a consistent surface finish with minimal chatter or tool marks.

Furthermore, the proper application of cutting parameters—such as speed, feed rate, and depth of cut—also plays a vital role in surface finish quality. The integration of advanced Cutting Inserts allows for the optimization of these parameters, enabling manufacturers to adapt quickly to various materials and machining conditions. Using the right combination can minimize tool vibration and related issues, leading to an enhanced surface finish.

Finally, the selection of the appropriate insert type for a specific machining operation is paramount. Inserts designed specifically for finishing operations tend to have sharper edges and tighter tolerances, which aid in achieving exceptional surface qualities. As a result, the right insert can help machinists reduce finishing operations by achieving desirable results in a single pass.

In summary, metal Cutting Inserts are integral to achieving high-quality surface finishes in machining. Their material composition, design geometry, specialized coatings, adaptability to cutting parameters, and targeted selection all contribute to better surface finish results. Understanding and leveraging these attributes can lead to increased efficiency and lower manufacturing costs, ultimately benefiting overall production quality.

Deep hole drilling is a machining process that involves producing holes that are typically more than six times the TCGT Insert diameter of the drilling tool. This process is used in industries such as aerospace, oil, and gas, and requires specialized tools such as deep hole drilling inserts.

However, deep hole drilling inserts pose significant safety risks if not handled correctly. As such, it is essential to understand the safety considerations when using these tools to minimize the risk of accidents.

Training

Before operating deep hole drilling inserts, it is vital to undergo comprehensive training to ensure safety. Training should cover the proper assembly, disassembly, and maintenance of the machine, as well as how to handle the inserts safely. Operators adept at deep hole drilling consider this as one of the most important safety measures of using deep hole drilling inserts.

Protective PVD Coated Insert Clothing

Deep hole drilling involves the production of high-velocity chips that can cause significant injuries. Protective clothing such as gloves, safety glasses, and proper clothing should be worn at all times when operating deep hole drilling inserts. The right clothing will protect the operator from high-velocity shrapnel and accidental contact with the drill bit.

Proper Insert Selection

Choosing the right deep hole drilling inserts for the material to be drilled is critical for safety. A wrong choice can lead to faster wear and tear of the tool, increasing the risk of accidents. As such, operators must have a good understanding of the materials they are working on and the optimal choice for inserts to minimize accidents.

Secure the Workpiece

The workpiece should be adequately secured before the drilling process begins. It should not move or rotate as this can cause the drill to break or the material to fail. Operators should be familiar with secure workholding techniques and ensure these are applied before drilling starts, to minimize accidents.

Proper Machine Maintenance

Proper machine maintenance is essential to prevent breakdowns and accidents. Operators should follow maintenance schedules and make sure that deep hole drilling inserts are in good condition. Worn out inserts should be replaced immediately, and damaged parts should be repaired before use. Regular maintenance will keep the machine in good condition, reducing the risk of accidents on the shop floor.

Conclusion

Deep hole drilling inserts are essential tools in many industries. However, operators must be aware of the safety considerations when using these tools, as any accidents can have severe consequences. Adequate training, the use of protective clothing, the right insert selection, securing the workpiece, and proper machine maintenance are essential to ensure that using deep hole drilling inserts is safe.

The Arbor Department at the Gleason Works Cemented Carbide Inserts (Rochester, New York) faced a capacity crunch about a year ago. Despite a process innovation, the crunch has eased but not vanished for this department, where they manufacture arbors, collets, setup gages--in fact, all of the workholding and setup devices for Gleason Works' line of gear processing machines.

The market for machines to process bevel gears has soared. The largest single market for these gears is in rear-wheel drive vehicles. The "truck" market has mushroomed, particularly since it now includes the very popular recreational pickup truck and sport utility vehicles with four-wheel drive; plus a continuing solid market for larger cars with rear-wheel drives. Another factor in the growth of this business for Gleason is a recently developed full line of CNC bevel gear processing machines with reduced setup Tungsten Steel Inserts times and enhanced flexibility.

Coincidentally, during this period, Gleason strengthened its line of CNC machines for processing parallel-axis (spur and helical) gear processing machines. Three years ago, the Phoenix CNC spur and helical hobbing machine was introduced and became a large seller. A CNC spur and helical grinder quickly followed. Then, with the acquisition of Hurth, a leading German gear machine producer, CNC gear-tooth shaving and honing machines completed the line.

The blessing of increased business brought with it challenges of capacity, backlogs and deliveries. In no department have those problems been more difficult than in the 67-employee Arbor Department. Most jobs are run in lots of three parts or fewer, so setup time is a major factor; it's just not a factor of running machines faster. Products are mostly custom-tailored to adapt the customers' products to the Gleason machines.

Until now, flexibility meant using a series of seven to eight machines, each with a skilled operator. Parts were turned, then milled in one or two setups, laid out for hole locations, and then drilled. "The process necessitated the moving and queuing of parts, multiple fixtures, multiple operators on all three shifts, and despite our best efforts, some tolerance stacking. In fact, when we looked for ways to boost our capacity and throughput, we never considered duplication or even augmenting that sequence," says Charles Menz, facilitator of the Arbor Department.

"We knew that we had to add significantly to our capability, and we had to do it quickly. We searched for a machine that could complete our parts in a single setup, and one that we could get into production in a hurry. We already had a Mazak Integrex 40, so we knew about the machine's multitasking capabilities and about our ability to use it.

"When we found that we could get a larger Integrex 50 built with the additional Y-axis, we bought it. The Y axis lets us complete all operations, including a substantial amount of milling, without removing parts from the machine."

The 40 hp main spindle goes to 3,000 rpm and produces 2270-foot-pound output for turning. The No. 50 taper rotary tool spindle has 15 hp output for secondary milling and drilling operations. Capacity is 27.95" maximum diameter and 40.43" length.

The Integrex 50 has augmented, not replaced, the traditional sequence of operations. Mr. Menz points out that they are still developing the tooling processes and the programs for the machine. In time, it will take an increasing percentage of the work going through the department. For example, on one of those products which are most likely to be repeated with some frequency, it will make more sense to develop the machine programs for them, and then have them available and optimized for the next time.

Mr. Menz explains, "We are programming off line, and then downloading the programs to the machine control. On the first run, the operator and programmer go through the cycle, looking for chances to improve the program and to perfect the cycle. When the job is finished, it will be that optimized program that is stored and ready for next use.

"We know that we can further reduce our cycle times and improve our efficiency on the machine. We are still working our way up on the learning curve."

The programmer, trained at Mazak, is learning about creating the best sequence of operations, cut depths, feeds, and speeds and tool choices (the machine has a 60-tool magazine and automatic tool changer). Two operators, also trained at Mazak, continue to hone their knowledge and skills. And Mr. Menz says that even the persons who work on process routing understand the concept of multitasking and explore all possible capabilities of the Integrex 50 with the Y axis. "Since we produce both rotating and prismatic parts, I challenge them to think `round' first and then prismatic. In most cases, we do the round portion of the workpiece first, and then turn it around in the chuck to finish the other end."

As with most multitasking CNC turning centers, the Integrex 50 has three axes of motion control; the C axis is spindle rotation in the feed mode, the Z axis is parallel with the spindle centerline, and the X axis is the vertical axis perpendicular to the Z axis. In addition, the Integrex has an optional fourth axis (Y) which is perpendicular to the Z axis, but it is horizontal, moving in-and-out across the part. It is the addition of this axis that simplifies the production of prismatic parts by cross feeding for milling or by producing off-center holes, for example. And at Gleason, it is this axis that takes the place of one or more milling and drilling machine operations in the traditional multi-machine production sequence.

In the setup gage, the Y axis mills the large flat and the flange. In the small expander, a saw-type milling cutter mills the grooves. The advantage on this operation is that the cutter does not have to be the same width as the groove, as would be required with an end mill. The cutter makes its first pass down the Z axis: then with a reposition in the Y axis, completes the groove on a return pass. Thus, the bottom of the groove is flat and the two side walls are vertical and perpendicular to the bottom. The same procedure is used to generate keyways and other longitudinal geometry.

According to Mr. Menz, standard procedure is to produce the round portion of the parts in the first operations, and then turn the part around in the chuck to complete the prismatic geometry.

Although, as Mr. Menz says, the department is still ramping up on the learning curve, and although the new machine is producing only a portion of the work in the department, benefits already are becoming obvious. "We are getting more precise parts, because we have virtually eliminated tolerance stackup," he explains.

"We also know that the department used to operate on the basis of a six week lead time. It is now down to four, which would mean that we also have eliminated a third of our work-in-process inventory."

"The same measure applies to the first problem: capacity, up a third."

The department is in transition. "In addition to our continuing improvements in efficiency, we are not finished with our process improvements. We are investigating Pro-Engineering/Pro-Manufacturing, which would permit us to download engineering data directly to the machines. And we have another Integrex in our short term plans."

As is always true, rapid business growth is accompanied by problems, frustration, hard decisions, and too many meetings. But at Gleason, no one seems to mind. MMS
