»contour-profiled« Technology
As often happens, world innovations stay hidden in the background, and no one thinks further about the manufacturing of various products in daily life, or did you ever worry about how exactly hair clippers are manufactured? LACH DIAMOND says it addressed this subject matter and proved once again the unlimited possibilities of »contour-profiled«…
»Cool Injection-Plus» PCD Milling Cutter
In November 2004, when LACH was awarded the German Innovation Prize for a newly developed technology for the cost and time efficient machining of aluminum components with a monoblock diamond cutter »dia-compact«, it was already said, “Nothing is more efficient than this … .” However, there was still something more efficient – as proven by the…
PCD Chipbreaker Type »3D-active«
LACH DIAMOND can look back on 20 years of experience in the development of PCD chipbreakers. The first CO-type patent was issued on January 26, 1999: A laser cut chip groove for PCD materials.
»contour-profiled« Diamond and CBN Grinding Wheels
Metal-bond profiled diamond and CBN grinding wheels are available for serial grinding of workpieces made of carbides, hardened steels and ceramics.Lach Diamond says its »contour-profiled« procedure is a cost killer in the best possible way. Previous grinding times with resin/hybrid-bond grinding wheels can be reduced by up to 60 percent.
»drebojet-plus« Diamond Dressing Roll
Lach Diamond says dressing with the diamond dressing roll »drebojet-plus«, which emerged from the PCD diamond dressing roll »drebojet« at the beginning of the 80s, is a noteworthy innovation simply because the presented type of drebojet dressing rolls for the CNC dressing respectively profiling of conventional grinding wheels are maintenance free…
»Dia-2200-mini« Spark Grinding Machine
The spark grinding machine »Dia-2200-mini« from Lach Diamond is for the production and service of diamond tools for the wood and composite industry. Its universal 5-axis CNC system is designed for the automatic sharpening of diamond tools and saw blades with up to 530 mm in diameter.
»PS-plus« PCD Drill
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«.
»IC-plus World`s Best« Chipbreaker
While CO-type chipbreakers only redirect the chips, LACH DIAMOND's new »IC-plus world`s best« chipbreaker will already guide chips with a cutting depth (ap) of 0.01 mm. The cutting depth can be increased up to the maximum length of the cutting edge, e.g. up to 5.0 mm maximum for an ISO cutting insert VCMT.
Type PS PCD Twist Drills
LACH DIAMOND says its newly developed PCD twist drill type PS saves up to 75 percent of time by reducing three previously necessary steps to one process. The new PCD twist drill completes piloting, drilling and reaming all in one “shot.”
Forming PCD Cutting Materials via Spark Erosion
In 1978, LACH DIAMANT discovered the use of spark erosion as a means of forming polycrystalline cutting materials and allowing for the production of rotating PCD tools, e. g. step drills and profile tools. Since then, PCD diamond tools have established themselves in metal, wood and plastic industries all over the world.
»Cool Injection-Plus« Monobloc Milling Cutters
LACH DIAMOND says its solution to combine the »Cool Injection« process, during which the cooling jet is guided by a PCD surface, and the chip controller »Plus« into one single tool proved to be ideal for manufacturing. Now it is possible to work with extremely high cutting speeds and feeds required for HSC machining.
PCD Milling Cutters
LACH DIAMOND PCD milling cutters, with diameters from 0.6 to 450 mm (and with integrated dust extraction systems for larger diameters), scoring saws, saw blades, drills, step drills and other tools are now successfully established in the composite industry – CFRP, GRP, wood, and plastic machining - for more than 3 decades. They are also used in…
»Dia-Fliese-perfect« Diamond Dressing Plates
