The CNC is 100 FANUC, the world's leading manufacturer of computer controls, including FANUC free 150-programming for special tools, digital motors and absolute pulse coders, which eliminate zero-return. But most important is FANUC's reliability and near perfect service record. USER-FRIENDLY ENVIRONMENT. SUPERIOR OPERATOR CONDITIONS. For the machine operator, the US-250 is a vast improvement in working conditions. The wide door with sliding top and bottom ensures the best possible upright working position for the operator. There is ample space for close-range tool inspection, without soiling the operator or work clothes with droplets of oil falling from overhead. The integrated oil-mist filter with 14m/min. capacity removes unwanted fumes from the operator's work space before he opens the door. To complete these comfortable working conditions, the operator panel is exactly where it should be, at elbow height, with panel and screen at optimal angles for work and vision. an uncompromising COOLANT FEATURING the US-250 is only offered with oil as coolant liquid. The advantage of using oil is the ability to keep grinding particles suspended in liquid until they reach the filter. INTEGRATED AIR-MIST EXTRACTION BY FILTERMIST The high volume, 14m per minute filter creates a vacuum around the door area thus removing fumes from the operator's working space outside and inside the machine. The air- centrifuge is shown connected to a central exhaust system as required in some countries. The filter can be equipped with an additional filter top for recycling of the air back into the workshop area. HIGH-PRESSURE COOLANT PUMP. With 16 bars and 100 liters per minute, the PROCESS INFORMATION coolant pump is dimensioned to supply enough oil for even heavy-duty production requirements. Ø Adjustable coolant nozzle directed at the grinding process. The machine relies only on oil as a coolant with steep and narrow oil-chutes with no sludge sedimentation possible. the advantage of a longer machine life and cleaner working environment even when grinding carbide.

Feed pump for centrifuge. High-speed centrifuge. Return into 800-liter clean tank. Overflow from clean tank into dirty tank. NT and FILTRATION system. The presence of a clean cooling liquid at all times lengthens the life of the machine and wheel life, while improving the grinding surface finish and the operator's environment in general. EASY-TO-CHANGE COOLANT SPOUTS. A real time saver. The unique high coolant pressure of the V1K1NG requires the use of metal tubing for the coolant nozzles. The adjustability of these nozzles is critical in eliminating grinding burns and with a change of wheel flange, the nozzles can be stored very conveniently to minimize future setup time.

US-250 model FIRST is the ultimate choice in a comparison between price and capacity. The concept of this model is to compete in price with much smaller 5-axis models, while maintaining the rigidity and capability of larger 5 and 6-axis machines. We have reached this goal by including all the necessary peripheral equipment. When it comes to grinding capacity, coolant oil filtration, and operator convenience, the V1K1NG US-250 has it all. THE WORKING RANGE. 1///Γ//VG The V1K1NG US-250 has an effective working range of 3 to 32 millimeters in diameter when grinding out of the solid with CBN or diamond wheels. Customers use our machine for tools 1 mm in di- ameter and smaller using a steady rest, although the machine is, by design, much too powerful for continuous work in this range. In re-sharpening conditions, the upper US-250 limit is determined by a maximum pos- sible tool diameter of 280 mm or the recommended maximum tool weight of 20 kg at 100 mm from the spindle nose. THE GRINDING SPINDLE. To grind 32 mm carbide tools, the machine is equipped with a very rigid spindle designed and built by V1K1NG. It is equivalent to a standard 0120 mm commercially available spindle. The dual-sided spindle allows up to 6 wheels to be used at one time, giving optimum flexibility in wheel selection. The flanges have a standard 150-35 male taper, combining strength and precision with low manufacturing costs. The wheel range is limited in size to 0300 mm with 0250 being the most economical upper limit. The lower diameter limit is governed by the maximum spindle speed of 8,000 RPM made possible by the built-in frequency converter. For long life, the spindle is oil mist lubricated using only the highest quality SKF bearings. A unique labyrinth seal prevents any dirty oil to penetrate from the outside during the spindle cool down period. WHY CHOOSE A SIX AXIS MACHINE? The U-axis is the technical feature, which most obviously differentiates the US-250 from the competition. The U-axis is indispensable when grinding full radius tools, where the ability to grind over the center gives an unsurpassed accuracy. For other tools, the U-axis offers the advantage of having a constant starting point for grinding. Your operator will quickly come to appreciate this advantage when grinding larger tools or using wheel packs. The X and Y axes are used for positioning and the U-axis for grinding. With this design, you always have a 250 mm axis stroke for grinding, regardless of wheel size, flange length, tool diameter, or length of tool. With the U-axis, the working range of the US-250 is thus very predictable and you will most likely never reach an over-travel alarm during the grinding of any standard tool. WEAR AND TEAR Our machine is designed for a long life and low-cost service. The prism guides of the X and Y axes are Teflon coated and protected by continuous oil lubrication, thereby providing a very high wear-resistant surface, low stick slip, and high vibration damping. The guides are virtually indestructible even in a crash situation. The wear and crash conditions are mostly absorbed by the ball screws, which are easy to replace at a relatively low cost
Your choice for AUTOMATION. PRO The U5-250 model PRO is one of the lowest priced automatic machines on the market. The simplicity of the loader design is very user friendly with virtually no setup time required. Model R-7, CNC Loader The PRO has all the features of the model FIRST with the added ad- vantage of a full coolant capacity of an unsurpassed 1300 liters/ 350 gal, tank capacity. The base of the machine serves as a coolant reservoir, helping to keep fluctuations in the thermal expansion to a minimum. The loader model is our 7th generation of automatic loaders for grinding machines. With our past experience we have made the loader with a definite focus on the following important features: less than one minute setup time. tool holders with high run-out tolerance. ability to load different shank diameters in one batch. The loading system relies on hydraulic tool holders, which are capable of maintaining run-out tolerances less than 4μ, without the use of complicated automatic steady rests.

Tool SOFTWARE with a focus. CNC Standard milling cutters, both end and side milling cutters, and staggered tooth are ground by the software package. This includes cylindrical, taper, radius, and corner radius tools. No programming is required. All data is entered in a menu with graphic screen help. ToolCAD is our very powerful profile generator. The operator enters the tool data in a WINDOWS 95 drawing environment, using a mouse only. The program will automatically calculate the grinding path, taking both flute rake angle and helix angle into account. This very complex calculation is completed in seconds, and the operator can view a simulated grinding path prior to execution for extra safety. Free 150 programming is always available on FANUC. Combined with the flexibility of a possible interpolation of all 6 axes, the possibilities for custom design of tools or precision ground parts are almost without limit. With the extra FANUC's option of the Macro B programming language, the skilled engineer can generate his own menu-driven software solutions, with automatic wheel wear compensation and other advanced facilities.
