1) TECHNOLOGY
Datron machining centers are designed and produced in Germany leveraging our company’s 35-year track record as a leading technology firm. From our origins in both electronics and software, we have pioneered the advancement of high-speed micro-machining through the introduction and integration of the following features: |
|
|
• 60,000 RPM Spindle
• Probing
• Ethanol Coolant
• Low-Power Technology
• IT Smart Components
• Automatic Tool Management

60,000 RPM Spindle: Today, there is a trend toward miniaturization in manufacturing. The abundance of intricate work pieces has resulted in a demand for small tools and an efficient means of running them. While, conventional CNC machines use big motors designed with enough force and horsepower to run large, rugged tools, these characteristics are devastating to fragile, small tools. But, since Datron’s singular focus is on the micro-tooling niche, all of our machines feature high-frequency, low force 60,000 RPM spindles. The blazing speed of the spindle evacuates chips, and the heat associated with them, from the cutting channel. It also results in lower machining forces and less vibration. All of this facilitates exceptionally high feed rates and improves the quality of the cut and surface finish.

Probing: Logically, the smaller the part is, the higher the need for accuracy is – because physically there’s less room for error. Datron offers a variety of integrated probing options that promote accuracy and quality control and even provide manufacturers with a product development tool by enabling reverse engineering.
Datron’s optional, but integrated Z-Correction Probe recognizes irregular work-piece topography and compensates for it dynamically. It does this by taking measurements along the surface of a blank and feeding that data into the machining controller. The controller automatically adjusts for uneven surfaces or work piece position. Through this process, job setup times are reduced and piece/part rejection is minimized.
With the addition of the 3D Extension, the Z-Correction Probe locates parts and material irregularities in the X, Y, and Z co-ordinates, finds centers of holes and bosses, pre-measures blanks before the machining starts, compensates for material variations, feeds data into ISO 9000 information chain for quality control, and even allows for the reverse engineering of many parts.
The omni-axis Renishaw TP20 probe is ideal for complex part measurement such as engraving a logo onto a rounded surface. Ordinarily, 3D programming would be necessary to accommodate surface depth changes and ensure an even depth engraving. With the TP20, the surface is scanned and irregularities or surface changes are automatically managed in the machining data without 3-D programming. The TP20 features a 6-way, kinematic, touch-trigger probe system to significantly improve cycle times.

Ethanol Coolant: Ethanol is a form of alcohol that results naturally through the sugar fermentation process and is environmentally friendly. It also happens to be an ideal coolant for high-speed, micro machining because a thinner-than-water viscosity allows the ethanol to quickly cover and cool more surface area on fast-moving micro tooling. The low evaporation point of ethanol makes it an efficient cooling solution and also eliminates the need for disposal and recycling, as well as their associated costs. Plus, ethanol coolants leave no residue on machined parts, which makes costly secondary operations, like de-greasing, obsolete — maximizing throughput, increasing efficiency and reducing labor costs.
Note: Ethanol coolant should only be used for machining of non-ferrous materials and Datron offers an oil coolant option for customers who machine steel-based materials.

| Low-Power Technology: Datron machines have lower power demands because they are designed with a smaller motor that is better suited to micro tooling. While most CNC machines run on 440 volt 3-phase power, using approximately 20 amps, our machines run on 208 volt single-phase power and use less than 10 amps — about the amount of electricity required to run a clothing dryer. Manufacturers who implement these machines decrease their energy consumption, which is good for the environment … and good for their bottom-line since it saves money on utility bills. |

| IT Smart Components: As a buyer, you’d never tolerate a car dealer who told you that the steering wheel was optional at an added cost. So, why would you consider a CNC manufacturer who makes you pay extra for the computer required to run their machine? Each Datron machine includes (as a standard feature) a PC with 256 MB RAM and 40 GB part/program storage, CD-ROM drive, 3.5” drive, USB port, monitor, keyboard, hand-held controller and our Microsoft® Windows®-based control software. This “open” system plays nicely with virtually any CAD/CAM software, provides Ethernet networking capability, as well as remote monitoring and control, and allows the machine to seamlessly integrate into any manufacturing environment. |

| Tool Management vs. Tool Detection: In the world of machining with large tools, monitoring spindle load can be used as a means of detecting breakage. If there is a fluctuation or drop-off in the current, then the operator knows that the tool might be broken. Unfortunately, the benefits of this “Tool Detection” process are limited because it is used only as a means of checking tools and reporting possible breakage without systematically replacing the broken tool. So, the best that a manufacturer can hope for is that the machine will shut off and prevent additional damage to costly blanks. Still, production time is lost — and if the tool breakage occurs early in a “lights-out” overnight shift, it can significantly impact schedules and revenue. Furthermore, this method doesn’t work when using micro tooling because the load involved is sometimes so small that the fluctuation in power usage doesn’t even register.
But, Datron’s Automatic Tool Management System™ is made up of three separate components working in synergistically — the tool checker, the tool changer, and the software. The tool checker is a mechanical sensor that measures tool length and detects the broken tool. The tool changer is a rack or tray that has space for spare tools and sockets where the machine places broken tools before picking up a replacement. Operators can stock the rack with spare tools, thereby having a ready supply should tools break during “lights out” operation. The software is a macro program that can be set up to run a tool check after executing a number of lines of code. For example, a tool check macro can initiate a check after every 500 lines of code by employing an “if/then” statement such as, “Measure this tool; if the length is shorter than the parameter (listed in the software’s tool database), then change the tool.”
