CoroCut QD, the reliable system from Sandvik Coromant for deep grooves and parting off with long overhangs, expands the offering of inserts and durable tools with over and under coolant. The system is supported with plug and play adaptors for easy handling and efficient coolant supply.
For bar feed manufacturers, process security in terms of good chip control and long reliable tool life is the key to an efficient production. To meet these needs CoroCut QD combines strong tools and inserts with rigid clamping and efficient coolant supply.
An important aspect for long tool life and few machine stoppages is good chip control. This is achieved by combining over and under coolant on all tools which keeps the temperature down at the cutting edge for less tool wear and a more stable performance, while at the same time providing for efficient chip evacuation.
Add to the support plug and play adaptors for easy coolant connection and a rigid, yet user-friendly clamping mechanism for easy insert changes, and you get CoroCut QD. This system not only ensures process security, but also easy handling for real machining efficiency.
At the cutting edge, the cutting forces are high. To withstand this temperature, the tool material has high fatigue resistance and the tool tip seat features a backstop so the insert stays in its position preventing the seat from wearing down when the insert is indexed. Also the inserts themselves are developed with good coating adhesion and high edge-line security, for long tool life in every parting off operation.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.
When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
Typical aero-engine components that the grades can machine are gas turbine discs, casings, blisks, spools, shafts and blades. But these grades also prove to be a great choice in demanding applications such as power generation turbines and medical implants made of cobalt-chrome
SigmaNEST 24 has expanded the Task Dialog to provide greater situational awareness to the NC programmer for handling multiple projects at one time. Within the Task Window, users can create and load jobs, access workspace task reports and apply new commands to multiple tasks. Users can also monitor…
The CoroMill MR80 assortment offers cylindrical and arbor cutter bodies, with diameters from 32 to 100 mm, 3 to 12 cutting teeth and even pitch and shim protection. All cutter bodies feature internal coolant supply. The double-sided E-L50 inserts offer true and easy indexing (6 + 6), with a 3 mm…
The next-generation CoroTap 100 and CoroTap 400, with optimized performance in aluminum, can meet very strict process security demands and offer a high level of reliability and consistent tool life. The CoroTap 100 straight flute tap features refined edge rounding that helps to remove burrs and…
The Zertivo 2.0 grades enable a 30 percent increase in cutting speed recommendations for the primary ISO P and ISO M application areas, as well as secondary ISO K and ISO S materials, thanks to their optimized flute shape, which offers effective chip evacuation. The grades designed for stainless…
One of the main advantages of the new CoroMill Dura aluminum-specific end mills is their versatile performance in all different types of roughing applications, while also offering finishing capabilities,” Wikström continues. “Up to 2×D full slot, pocketing, 5–20° ramping, shoulder milling and more…
So how does Y-axis turning work? As the name implies, the new method makes use of the Y-axis, and all three axes are used simultaneously when machining. The tool rotates around its own center, the insert is placed for machining in the Y-Z plane and the milling spindle axis interpolates during…
Beyond shoulder and face milling, the end mills can also be used for pocket milling, helical interpolation, ramping and slot milling. The CoroMill 316 is part of the Sandvik Coromant Optimized Solutions offering in the company’s solid round tools range.
CoroTurn Prime B-type inserts are available for external and internal turning in a range of high-performing grades, including the new steel turning grades GC4415 and GC4425. Programming support is available in the most common CAM platforms and with CoroPlus Tool Path for PrimeTurning.
Based on a technology platform similar to the existing CoroMill® 345, this new milling concept offers a 40 percent lighter cutter body with shim protection and a high number of inserts for secure and stable machining, even in vibration-prone overhang applications. The 89.5-degree approach angle…
