Three Edged Drills Address Chip Removal Concerns

Kennametal says its PCD round tools for aluminum machining deliver up to 10 times higher productivity than carbide tooling. The new line of drills, reamers and end mills provides enhanced tool life and wear resistance even in abrasive aluminum alloys and is available with very short lead times.

“Our new PCD round tools line enables our customers to machine aluminum significantly faster, for greater productivity on the shop floor,” says Michael Hacker, product manager at Kennametal. “In drilling and reaming operations, these tools consistently perform at cutting speeds of up to 900 m/min (3,000 SFM). Milling operations can be performed at 6,000 m/min (20,000 SFM) – far higher than non-PCD tooling.”

Kennametal also says the PCD round tools’ through-the-tool coolant capabilities and MQL-ready interface make them useful for both rough and finish machining. It continues by saying the tools’ sharp cutting edges and low-friction rake surfaces reduce the chance of built-up RCMX Insert edge, while low-friction machining enhances surfaces in finishing operations like reaming. The company also says its PCD round tools can achieve surface roughness of Ra 0.1–0.8 μm (0.0025–0.02 μin) – smoother than with conventional carbide tooling – and perform well with high-silicon-content aluminum such as that used in the automobile industry.

Kennametal’s line of PCD end mills features 6 to 50 mm-diameter tools; cutting depths up to 50 mm; various rake angles; and center-cutting, roughing and finishing geometries. Its PCD drill offering features 6 to 20 mm-diameter tools in 0.5 mm increments, body lengths up to five times the diameter body lengths and inch and metric sizes. The company’s PCD reaming portfolio offers 6 to 20 mm-diameter Carbide Aluminum Inserts tools in 1 mm increments, through and blind-hole versions of tools and a PCD modular reaming system with KST coupling for larger diameters up to 42 mm.

From Manual To CNC Mills： A Three Phase Transition

Mastercam 2018 Mill expands machining flexibility and emphasizes speed and automation with 2D high-speed tool paths, 3D enhancements and multi-axis features.

Stock awareness for select 2D tool paths enables tool motion on the top, bottom or both values of the stock, providing safer and more optimized tool motion. Users can also optimize finish passes based on rough stock, providing  more efficient and safer tool motion. Dynamic Mill tool paths support plunge entry. Spring passes can be used to create additional finish passes with a spacing of zero between them. This can be Carbide Grooving Inserts used for parts with thin material that may have flexed away from the tool during previous passes.

Streamlined workflows for 3D high-speed tool paths give users fine control over where to cut. High-speed Hybrid tool paths with smoothing controls deliver a finer finish, requiring less handwork. Follow containment has been added, enabling the tool to follow the containment boundary back to the start of the cut, thereby creating clean and closed passes. It also helps to avoid partial cuts when a containment boundary is directly on top of a vertical surface.

Among the software’s Multiaxis improvements, common direction on select tool paths keeps the tool at a uniform tilt angle to reduce tool and machine motion. Dropping on three- to five-axis tool Coated Inserts paths projects the three-axis tool path onto the selected surfaces, adjusting the tool vectors to be normal to the surface. The redesigned Multiaxis Link Safety Zone page better reflects parameters.

Haimer USA, Fullerton Tool Sign Licensing Agreement

The machining of complex workpieces often requires the use of a number of cutting tools. However, conventional, large-capacity tool magazines can take up a significant amount of floor space and lead to long tool-to-tool changeover time. To maximize the number of tools that a machine can access in a minimal amount of floor space, DMG/Mori Seiki has developed the ISO-50 Matrix magazine. (This was shown in use with the company’s DMC 80 U Duoblock machine at a recent open house at the Deckel Maho facility in Pfronten, Germany.) The ISO 50 Matrix combines rack and wheel magazines to accommodate 549 cutting tools while occupying just 8.6 square meters of floor space. It also enables CNC Carbide Tool Insert the machine to realize a chip-to-chip tool change time of 4.1 seconds.

The rack magazine has room for 512 tools, while the upstream wheel magazine nearer to the machine holds 37. The machine’s toolchanger has direct access to both the rack and wheel magazines. The ISO-50 Matrix is compatible with many different tools ranging in size from 100 mm in diameter to 280- by 400-mm bridge tools. The maximum tool length when used with a
DMC 80 U machine, for example, is 550 mm.

Setup operations are possible both at the rack magazine and the tool-loading station of the wheel magazine. In fact, complete toolboxes can be unloaded from the rack magazine. Each box can accommodate 96 tools with diameters as large as 100 mm. In addition to maximizing the number of tools available to a machine, significant tool capacity frees operators to perform value-adding secondary work during Carbide Drilling Inserts machining.

The ISO-50 Matrix is available with options including tool identification, mechanical tool breakage detection and brush taper cleaning.

Grinding Wheels’ Bond System Enables Sharper Cutting, Less Vibration

The You Ji DSM series of heavy-duty duplex milling machines, available from Absolute Machine tools, is engineered specifically for two-, four- or six-sided production squaring and chamfering of square and rectangular workpieces. Depending on the machine configuration, end users can machine blocks as small as 0.750" × 0.750" (19.05 × 19.05 mm) and as large as 47" × 47" (1,175 × 1,175 mm) in maximum thicknesses ranging from 6" (150 mm) when using a 10" cutter, to 16" (400 mm) with a 16.5" cutter.

The duplex spindle design enables simultaneous two-sided milling that produces consistent parallelism and perpendicularity as well as tight tolerances and fine surface finishes. The twin milling heads move on rigid box ways along the Z axis. The heads feature variable-speed NT50- or NT60-taper spindles and provide 15 or 30 hp, depending on the machine model. The spindles produce Indexable Carbide Inserts high levels of torque at low rpm, permitting effective use of large-diameter cutters, the supplier says.

The rotary worktable moves in the X axis on roller-type linear ways and indexes from 0 to 315 degrees at 45-degree intervals. Hydraulic clamping and Hirth couplings combine to produce positioning accuracy of ±0.0003" and repeatability of 0.0002". Heavy one-piece cast-iron machine bases optimize machine rigidity and minimize thermal displacement.

Machine operation is semi-automatic: workpieces are shuttled in manually, then automatically centered, clamped and checked. Clamping pressure increases in steps to expedite accurate centering and provide sufficient clamping force to eliminate chatter. Modular clamping fixtures can be tailored to specific workpiece shapes.

Every DSM machine is equipped with a VNMG Insert Mitsubishi C-70 control with a touchscreen interface and human-machine interface (HMI). Operator-friendly software speeds setups and reduces change-over time by enabling the setup of subsequent jobs while machining is in process. A Cutting Memory Module stores workpiece-material-based cutting data that can be applied to new parts.

Gantry Loaded Chuckers Turn Up Productivity

When CNC machines are properly used, they are flexible, productive, long-lasting and safe. A misused machine or a mishandled application can have just the opposite results.

Typically, the most egregious offenses should be obvious and easy to avoid, but not all serious issues are easy to spot. The issues presented here are commonly missed by operators and can cause big problems for your CNC environment.

Most cutting tools are available in right- and left-hand versions. The most obvious effect of tooling style is on spindle direction, but a lesser-known impact applies to CNC lathes when powerful machining operations like rough turning, facing or boring are involved.

When performing a powerful machining U Drill Inserts operation, you must confirm that the force of the operation is driven into the machine’s direction of support. Doing so will stabilize the process and ensure that the machine will continue to provide adequate support for years to come.

If you run the wrong “hand” of tooling versions, the force of the cutting operation will pull the way system apart. The only support will come from the integrity of components comprising the way system, which will degrade over time and bring about play in the way system. Eventual symptoms could include sizing issues, degraded surface finishes and chatter.

Bar operations involve machining a part, cutting it off, feeding the bar and running the next part. When a company is faced with a bar application for the first time, and especially if it does not foresee similar jobs coming up in the future, it may understandably try to minimize costs. Instead of using an expensive bar feeder, it might try to utilize an inexpensive bar puller held in one of the tool stations. With bar feeders, the bar is fully enclosed and supported within the bar-feeding device. With bar pullers, the only support for the bar will be the spindle itself.

Depending on the diameter of the spindle hole and that of the bar, the spindle may not allow the bar to flex within the spindle during machining. The faster the spindle speed in revolutions per minute, the more bending stress will be placed on the bar. Again, most bar-pulling applications work nicely if the bar is not so long that it exits the rear of the headstock/spindle. If it does by even a small amount, the rotational stress will bend the overhang by 90 degrees. If the bar hangs out far enough, it will mangle the spindle motor and anything that gets in its way.

Most M codes are like programmable on/off switches: spindle on/off, coolant on/off, door open/close, etc. If the machine has accessories like a special coolant system, rotary table or chip conveyor, M codes are likely involved with each.

Without a thorough understanding of every M code, a programmer may unwittingly cause issues with machine longevity. Many rotary axes, for instance, incorporate clamping systems that secure the rotary axis in place when necessary during powerful machining operations. This requires programmers to use an M code to clamp the rotary axis prior to machining. If the programmer is unaware of the clamping M code, the clamp will not engage, and undue stress will be placed on the rotary axis.

I have seen all manner of remedies employed to keep a needed CNC machine in production, even if it had serious maintenance-related issues. Misaligned turning center headstock after a crash? The operators? programmed tapering movements for straight diameters to compensate for the misalignment. Bad check-valve in the coolant system? They included a multi-second dwell after turning on the coolant to allow time for the coolant to flow at its maximum rate. Accessory devices without confirmation signals? Operators programmed a dwell command to allow the device time to complete its activation.

No machine issue will correct itself. The problem will almost always degrade and cause serious issues.

A lot of engineering goes into every CNC application. While there may be some flexibility for certain aspects of the application, operators must always adhere to the guidelines you have implemented — and most do. However, I have seen operators manipulating functions they should not.

For instance, there are operators who increase or decrease feed rate and spindle speed override functions. While there are appropriate reasons for operators to use these functions, they may instead be increasing these functions just to make parts faster or decreasing them to keep from having to work so fast or hard. In one company I visited years ago, the operator had turned the feed rate override switch to 150%, removed the switch pointer and replaced it in the 100% position. To High Feed Milling Insert any onlooker, it would appear the feed rate override switch was set to 100%.
