The FANUC high-performance control has been developed exclusively for the cylindrical grinding industry. The canned cycles and the custom Macro B package featured in the control give the machine the versatility and speed demanded to accomplish your grinding needs. With the marriage of the FANUC control and the ECOTECH GRINDER, we have developed a state-of-the-art CNC Cylindrical Grinder with the simplicity of programming today’s most complex parts.

As a global leader in the grinding machines, Ecotech CNC Grinders have heavy aged cast iron construction, precisely machined and hand scraped. With a hydrodynamic spindle, the bearing load capacity is created by shaft rotation. Hydrodynamic bearings have the best damping characteristics of all bearing types and this allows extremely high speeds to be achieved. The wheel size 24" x 3" x 12" is larger than most products from other brands. With a 15hp motor on the wheel head, it produces a high material removal rate.

The standard workhead has an MT # 5 and the tailstock has an MT #4 size bore. The spindle on the workhead is a dead type (optional Live/Dead is available) and it utilizes a drive plate to drive the part. The workhead speed is controlled by a VFD that is standard and simplifies the procedure to change the workpiece rpm. There is a JOG button on the workhead which is ideal for indicating and setting up the workpiece. The tailstock has an adjustable spring for adjusting the holding pressure. To retract the quill there are two methods, a hydraulic foot pedal or a manual hand lever.

GC12 Series Information

All GC12 series machines have a 10° slant table which is easy to clean and guide the coolant fluid back to the machine reservoir. The 10° slant provides the gravity force to keep the workhead and tailstock stand on the table and against the grinding normal force, enhancing the rigidity and efficiency of grinding. The Z-axis positioning accuracy and repeatability is assured with an AC servo motor and a high precision ball screws. The lubrication design is similar to the wheel head guideways the multi-point flow adjustable lubrication system together with the high accuracy hand scraped ways ensures the table travel movement without any stick-slide on full table speed range even when the speed is low to 4 inches per minute. The table also has a built-in swivel system with a stand for the dial indicator for the tapered adjustment of the parts.

Turn-key/automation for high production applications, Ecotech offers solutions with several automation possibilities, fitting the customer´s requirements. The loading system varies depending on the part´s specifications.
