»Dia-2200-mini«

The new concept for servicing diamond tools ... also a result of more than 30 years successful constructing of EDG spark erosion machines for PCD processing »Dia-2200-mini« Edition

More than 30 years after the discovery of the spark erosion by LACH-DIAMANT we have a premiere again the "mini" the great alternative to the »Dia-2100-classic« for PCD processing.

The concept of the »Dia-2200-mini« fulfills the worldwide increased and changed requirements for the service of diamond tools (PCD).

In the first place is this valid for diamond tools for the processing and machining of known wood and wood-like materials, PCB circuits board material, plastics and non-ferrous metals.

The tradition at LACH-DIAMANT started with the legendary »M-1050 automatic«, subsequently a number of special features were developed for the "mini" which facilitate an easy handling for diamond service operations.

Exemplary is:

the modern menu navigation on the monitor (see photo) based on Microsoft Windows^®
the precise 3-D calibration of individual tools or tool sets
the simple and quick retrofitting of the machine for different tool types
the ergonomic layout with the advantage of direct proximity to the machine and tool
high production safety by the triple safeguarded fire protection system (fire warning + 2-times fire extinguishing system)
the compact construction of the machine has been designed with a small foot print and all aggregates are easily accessible

»Dia-2100-classic«

The Universal Automatic Sharpening Machine for Service and Manufacturing of Diamond Tools and Saws

The »Dia-2100-classic« Edition 2005 was developped as an universal automatic sharpening machine for production and service.

The »Dia-2100-classic« Edition 2005 fulfills all requirements for the sharpening of diamond tools for wood, plastics, circuit boards and laminate flooring presently on the market.

LACH DIAMANT, like no other manufacturer, can look back at more than 30 years of experience (since 1973) in the development and manu - facturing of polycrystalline diamond tools (PCD).

The »Dia-2100-classic« Edition 2005 can be easily operated without special programming knowledge, suited also for newcomers in the service / sharpening business as well as for production.

The »Dia-2100-classic« Edition 2005 has an active menu guide at the monitor based on Microsoft Windows^®, supported by graphic depictions and video presentations. With this, an assured operating sequence, starting with the set-up of the machine, selection and measuring of the specific tools, sharpening process and final control is given.

In addition, the »Dia-2100-classic« Edition 2005 can be connected to the newly developped »dia-ToolNet« which allows the measured tools and their stored data to be externally recalled from the »dia-ToolNet« station.

The »Dia-2100-classic« Edition 2005 has been equipped with the further developped spark generator EDGplus. Surface qualities, depending on PCD quality, of Ra = 0.2 μ and better, are obtained with copper or the easier to handle and less expensive electrographite discs.

The »Dia-2100-classic« Edition 2005 can be equipped with either single or multiple tools and is also suited for sharpening operaton.

The »Dia-2100-classic« Edition 2005 is universally designed so that it is capable of all types of operations regardless if they involve shear angled jointers, bits or router bits, profile tools, grooving tools, scoring tools, hoggers or saws (for example see images at the top).

The programmes included in delivery allow multiple manufacturing in one spindle set-up, such as hogging heads or saws up to Ø 800 mm, scoring (also for circuit board processing PCB), sheer angled jointing cutters, etc.

The handling system »ecomat« for series production and service of diamond routers is offered as an option for subsequent installation.

»Dia-ToolNet« Station

The »dia-ToolNet« and the »dia-ToolNet« Station

The »dia-ToolNet« is a modern universal measuring and re-positioning device with an integrated tool server comprising the »dia- ToolNet« Station that can be connected so as to form a network with all the CNC-controlled LACH DIAMANT universal sharpening machines.

The measuring system is based on a highprecision telecentric camera with maintenance-free LED illumination. All the images taken by the measuring camera are evaluated by a computer in real time and displayed on the 10" TFT monitor. As easy handling was a top priority for the software developers it is possible to operate the measuring system after only a few minutes of instruction.

Classical measuring errors - such as the parallax error - which are common when using the projector-based measuring devices, have been eliminated with the »dia-ToolNet« Station. This system allows for error-free and fast gauging of measuring profile radii, angles and tolerances of dia-cutting edges (and of course also carbide, Stellite, CBN cutting edges, etc). Furthermore, the top illumination, that can be additionally activated, enables very exact determination of dia-cutting edge breakage.

The »dia-ToolNet« station, however, is more than just a classical measuring device. With a second 10" TFT monitor the normal tool editor of the »Dia-2100-mini« and the »Dia-2100- classic« is always available. The operator can thus define new tools for the LACH DIAMANT sharpening machines already on the measuring machine. For example, starting with customer or job data, through the tool geometries to the exact calibration data, thus eliminating errors in the setting up of the machine right from the start.

The chief attraction of this tool editor is its ability to communicate directly with the measuring software of the camera measuring system! All the measured cutting positions are automatically recorded in the tool editor. Manual transfer, the writing and typing in of data, which is usual for example with normal measuring devices where it represents a major source of errors, does not exist with the »dia- ToolNet« station.

The »dia-ToolNet« station is thus the optimal device for job preparation and quality check of dia-tools.

The »dia-ToolNet« station also features an integrated server, which provides tool data to all LACH DIAMANT CNC sharpening machines.

The server is a Windows^®-based industrial PC with an integrated RAID harddisc. With this system no data can be lost, not even if the harddisc is damaged!

Several possibilities are available for data exchange: the Ethernet based network »dia- ToolNet«, modern USB (memory-)sticks and the classical diskettes.

»Dia-2100-CNC«

For all diamond tools and saws - from the universal individual manufacturing to multiple and series manufacturing

The »Dia-2100-CNC« was developed as an universal sharpening machine in order to assure the sharpening of all diamond tools on the market for the wood and plastic industry.

LACH-DIAMANT, like no other manufacturer, can point out to three decades of experience, since 1973, in the development and manufacturing of polycrystalline diamond tools (PCD).

The »Dia-2100-CNC« can easily be operated without special programming knowledge. Ideal for the diamond tool newcomer, for sharpening service or for production.

LACH-DIAMANT placed special emphasis on manufacturing high precision, long service life components and machine rigidity for 24-hour operation. In addition, LACH-DIAMANT developed simple operating instructions.

The »Dia-2100-CNC« 2003 Edition is equipped with the improved spark generator »EDGplus^®«. Surface qualities of Ra = 0,2 μm and better, are obtained with copper wheels or the (simpler to operate and less expensive) electrographite wheel.

With the installed 3-D measuring system the dependability of the total concept is complete. From the initial to the final inspection, the diamond tool is monitored in the machine during the sharpening process and, if desired, the report can be printed out with the supplied printer (see illustration above).

The new »Dia-2100-CNC« 2003 Edition can be equipped with either single or multiple tools and is also suited for sharpening operation.

The »Dia-2100-CNC« is universally designed so that it is capable of all types operations regardless if they involve shear angled jointers, bits or router bits, profile tools, grooving tools, scoring tools, hoggers or saws (for examples see the right notebook).

All programmes include simple operator instructions.

Multiple manufacturing in one spindle clamping (example: hoggers illustration) or saws up to Ø 600mm, scoring tools and shear angled jointing cutters - easy processing - possible with special programmes already included in the price.

Series manufacturing and service of diamond routerbits by means of handling system »ecomat« (see illustration). This is available as an option and can be installed later. ...and all of this dependable and precise - just the proven LACH-DIAMANT machine quality.
