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.
The »Dia-2200-mini« combines sharpening programs for new production and service of Dia end mills and Dia jointing cutters with and without axis angles, Dia scoring saws, Dia saw blades (all tooth types) as well as – at no additional cost - profiling programs (contour-controlled with copper electrode or in-feed with graphite electrode).
The program for multiple production is also available at no additional cost – automatic sharpening of multiple Dia tools or, for example, axis angle jointing cutters.
A new axis angle program allows for extreme axis angles of more than 45° during production and service. A decisive factor for the development of this program was the tremendous increase in the variety of different materials during recent years.
One example: Fiber composites are booming – glass fibers (GRP) in the recreational industry, carbon fiber-reinforced plastics (CFRP) in aircraft manufacturing or agricultural machine industry and now also basalt fabrics in the automobile industry.
In the furniture industry, the “zero joint” due to new machine technologies, should be mentioned.
The universal grinding machine »Dia-2200-mini« is equipped for these challenges during new production and service of tools with this program for extreme axis angles. During the subsequent use of the tools, impeccable milling results and flawless surfaces can be expected for composite workpieces, without any reworking being required, according to the company.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding machine
Powers a grinding wheel or other abrasive tool for the purpose of removing metal and finishing workpieces to close tolerances. Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its “finishing” role, the grinder is perhaps the most widely used machine tool. Various styles are available: bench and pedestal grinders for sharpening lathe bits and drills; surface grinders for producing square, parallel, smooth and accurate parts; cylindrical and centerless grinders; center-hole grinders; form grinders; facemill and endmill grinders; gear-cutting grinders; jig grinders; abrasive belt (backstand, swing-frame, belt-roll) grinders; tool and cutter grinders for sharpening and resharpening cutting tools; carbide grinders; hand-held die grinders; and abrasive cutoff saws.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
- sawing machine ( saw)
sawing machine ( saw)
Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
