A large portion of Automec’s business today is replacing older backgauge systems like Hurco®, Dynabend® and our own Automec systems. While this is the preferred course of action we do find that some customers need a more economical alternative during these times. Oftentimes, the mechanical portion of the backgauge is in good shape but the electronics are obsolete or becoming too costly to troubleshoot and repair. WE HAVE A NEW SOLUTION!
Automec has developed an upgrade kit for Autobend® S4, S6 and S7 that replaces the Hurco® control and electronics with Automec’s CNC150 control and electronics. The Hurco® mechanical structure needs to be in good working condition, but the electronics do not matter as we replace the servo amplifiers, encoder, cables and all other components with the exception of the motor. The Hurco® DC motor is usually in good shape and only needs replacement in rare instances. We currently do not offer upgrades for dual motor/dual ball screw Hurco® backgauges.
The CNC150 control will perform exactly as you know it and the Hurco® backgauge will position with approximately the same speed, accuracy and holding force of the traditional Hurco® system. All Automec supplied components come with a one year warranty.
In this difficult economy you might actually save money over repairing your existing system and the new control will last you another 10-20 years!
All Hurco servo boards, cables, control head and control boards can be eliminated as the Automec upgrade replaces all of those components.
The only other requirements are that the Hurco mechanical assembly, bearings, ball nuts and shafting are in good shape with no binding or mechanical looseness.
Hurco upgrades are done either by sending the Hurco main casting and moving carriage back to Automec or by sending just the motor to Automec. In the first case, we take care of everything and you get a complete running system back. That is simpler than doing the retrofit yourself but you have higher freight costs both ways and the backgauges are quite bulky to handle. Sending just the motor back requires paying attention to a few details because there are slight variations between different vintages of the S7 Hurco.
When sending the assembled mechanical structure to Automec, we only need the main frame, with moving carriage, ball screws, Thompson shafts, bearings and motor. We do not need the vertical uprights, gauge bar, fingers or the mechanical auto advance ram switch and control boxes or cables.
The assembly should be clean and degreased as we do not perform any functions on the mechanical components.
You get back a working, tested hybrid system with all cables and electronics (except the motor) replaced by Automec.
The S4 is the older of the Hurco® backgauges. The existing Hurco® servo for the X-axis motor is located in a remote electrical enclosure with the PC boards for the control. The original S4 backgauges utilize “hall effect” sensors to accomplish zero referencing (calibration). The motor and encoder are located in the mechanical structure and the Hurco® motor is re-used in its same position for the upgrade. Automec adds its own encoder to the rear of motor1 and eliminates the “hall effect” sensors, replacing them with a simple plunger microswitch. Again, all electronics including the data entry panel, servo amplifier, encoder, and all cables are replaced by Automec.
These are the newer version Hurco® mechanicals and the “hall effect” calibration sensors have been eliminated by Hurco® in favor of a roller micro switch for X-axis calibration. Automec utilizes that switch as well as the Hurco® motor which is usually in good shape1. We replace the encoder, the data entry control and all other electronics including the motor servo amplifier (which is located beside the motor in the mechanical structure). We leave the motor servo amplifier there, but it performs no function so you can remove it if you desire. The Automec servo amp is located remotely in its own enclosure and we provide and wire the cables that connect back to the motor, encoder and calibration limit switch.
The ram axis can also be upgraded whether or not there is a Hurco® ram axis in place. Procedures are different depending on what type of pressbrake you have.
When there is no Hurco® ram axis in place, just use standard Automec ram axis pricing and proceed as if the whole system is new. In other words, add the new Automec ram axis price to the price of the upgraded X-axis.
The Hurco® ram interface board must be removed from the pressbrake electrical enclosure and the pressbrake brought back to the way it originally worked with the microswitches mounted to the side of the pressbrake. Test that operation and provide Automec with the original pressbrake electrical schematic. We will mark up the schematics with instructions on how to wire the Automec ram axis relay board inside the pressbrake electrical enclosure. Automec also provides a new linear scale so all Hurco® ram axis components can be eliminated. Automec can remove the old Hurco for $685.00 when coupled with the standard Automec installation fee of $2,730.00 OR you can do it yourself.
Send the Hurco® ram adjuster mechanism in good condition complete with motor1 to Automec. We utilize the Hurco® motor and retrofit our own encoder and cables so the ram axis will simply bolt back up just the way you removed it. The Hurco® micrometer barrel and motor housing will look externally the same as before. We provide a new servo amplifier for the Hurco® motor housed in a separate enclosure identical to the X-axis servo.
Consult factory – These are very doable but there are so many variables you must consult factory.
1 Note: All pricing and procedures assume the Hurco® motor is in good shape. The motor usually has a pretty long life - it is the other electronics and amplifier that tend to wear out. In the rare instance that we find the motor is bad you have the option of purchasing and sending us another or we can provide one for additional cost.
