The new Sandvik Coromant solid carbide micro drills offer outstanding performance for holes from 0.073 inches to 0.116 inches in diameter. The CoroDrill 862 has a thin TiAlN coating that helps retain cutting edge geometry and provides a smooth surface for chip evacuation. This helps prolong tool life in workpiece materials that include steel, stainless steel, cast iron and aluminum.
The innovative post treatment on the CoroDrill 862, combined with specially designed point geometry, reduces the thrust forces and promotes fast and efficient chip removal. This is aided further by Advanced Chip Management (ACM) flute geometry, which helps evacuate the chips. This is vital in micro-drilling as even the smallest accumulation can lead to problems such as drill breakage, loss of precision, downtime and scrap.
The CoroDrill 862 also provides good hole entry and exit, and achievable hole tolerance of IT8-IT9. Internal coolant holes deliver coolant directly to the tip of the drill, even at deep drilling depths, to further assist precision and chip removal.
Available in drill lengths of 8-12 x D, the drills are only for use with HydroGrip high precision chucks from Sandvik Coromant.
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.
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…
