In a recent article about CNC Toolholders, we compared traditional “steep taper” milling machine toolholders to their dual-contact HSK and Big Plus alternatives. This time, we'll explore the CNC turning equivalent, a.k.a. quick-change toolholders. As their name suggests, these aftermarket devices make swapping out a broken drill or worn turning tool fast and easy. The result [...]
Kent CNC has introduced the New KHV-500 Combination Horizontal/Vertical Machining Center with the industry standard 0i-MD control by FANUC. By combining a horizontal machining center with a vertical machining center, this cutting-edge versatile machining center allows for faster setups and parts loading and unloading, improved accuracy, floor space maximization, and capital investment reduction. Two Spindles Are [...]
Thinking about changing out your CNC toolholders? Big decision. Most machining centers today come standard with a CAT or BT-style spindle interface, and for the lion’s share of milling operations, these do the job quite nicely. But sometimes, an alternative to traditional “steep taper” CNC toolholders is in order. Source: nextgentooling.com Choose the Right [...]
The rigger just called. Your first CNC lathe or machining center will arrive this Friday. You unpacked the toolholders last week. The workholding is ready. You’ve lined up the first few jobs. The big question now? What approach will you take on CNC programming? Will you buy a CAM system and sit through a training class or two? Or will [...]
High-speed machining was once a niche technology, known only to aerospace shops making large airframe components. No more. High-speed machining (HSM) use is now widespread. So are its counterparts high-feed (HFM) and high-efficiency (HEM) machining. All are now common in shops of all sizes and specialties. That said, shops wishing to pursue a more productive path [...]
Automated Machine Tending is No Longer an Option. Time to Hire a Robot! Given the ongoing shortage of skilled labor, shops everywhere are turning to automated machine tending. Doing so reduces operating costs. It increases overall equipment effectiveness (OEE), often significantly. Automation also opens the door to unattended second and third shifts, potentially allowing the company [...]
Anyone who's watched an expensive carbide drill go up in smoke knows the importance of cutting fluids. And yet, the challenge is getting these fluids where they're needed most: in the work zone. That's where through-spindle coolant comes in. A common option on some brands of CNC machining center, "coolant-thru" increases tool life, productivity, and part [...]
Let’s pretend you just bought a KVR-series machining center from Kent USA. Furthermore, your shop cuts tons of aluminum, so you opted for the 20,000 rpm high-speed spindle option. Great idea. What’s not so great is overlooking the need for toolholder balancing at these speeds. That’s because an unbalanced toolholder will not only shorten tool life, it might just [...]
At first glance, gang-style lathes like this one from Kent USA appear limited in their capabilities. There’s some truth to that statement. After all, even the largest of the series—the GSL-42—boasts a maximum bar diameter of 1.6" and 6" of Z-axis travel. How many parts do you know that fall into this size range? If yours [...]
Trying to choose between horizontal vs. vertical lathes for your machine shop? There’s more to the decision than spindle orientation. Workpiece size and shape plays a big role, with vertical turret lathes (VTLs) winning the prize for large diameter parts, provided they aren’t much longer than they are wide. Traditional “horizontal lathes,” on the other hand, [...]
