Based on the previous success of PCD drill type »PS« during burr and delamination free machining of fiber composites – also in combination with aluminum – so-called stacks components – Lach Diamond developed the PCD drill type »PS-plus«.
»PS-plus« drills show highest efficiency and quality for a diameter range of 2.5 up to 12 mm and time savings up to 75 percent. A long tool life makes »PS-plus« drills the ideal choice for maximum machine utilization and unmanned shifts, according to the company.
The trouble-free use of these PCD drills normally saves two to three previously necessary work steps, such as pre-drilling/drilling of pilot holes, drilling and even reaming when aiming for burr-free quality up to h6. Optimal chip removal is guaranteed via MQL or coolants. For drill diameters over 5.0 mm, »PS-plus« drills will be delivered with internal cooling.
»PS-plus« drills are designed for maximum cutting speeds and feeds and therefore guarantee shortest cycle times.
PCD drills type »PS-plus« are superfast tools for serial production and drilling into solid material, e. g. for all aluminum or die-cast housing components, extruded or drawn parts, aluminum turning parts and in general for all pinhole, thread and core drilling from 2.5 to 12 mm.
»PS-plus« is also available as step drill tool.
Moreover, type »PS-plus« PCD drills are suitable for aluminum and fiber composite components in automobile and aircraft manufacturing industries.

Stringy portions of material formed on workpiece edges during machining. Often sharp. Can be removed with hand files, abrasive wheels or belts, wire wheels, abrasive-fiber brushes, waterjet equipment or other methods.
Materials composed of different elements, with one element normally embedded in another, held together by a compatible binder.

polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
