This 20" long bed jointer with a Tersa cutterhead, manufactured by SCM, features extra long 180 inch cast iron tables and Smart Lifter cutterhead guard planer protection. The L’invincibile F 7 is the heaviest duty, long bed 20” jointer designed to meet the needs of high production shops. Standard features abound on this machine to make it as productive, efficient and dependable as possible without sacrificing safety.
Extra-long Cast Iron Tables
All SCM Jointers use aged cast iron tables that are machine polished to the highest tolerances. These castings are ribbed to ensure maximum strength and to avoid problems with the tables warping or breaking during use. The longer tables ensure board straightness. The L’invincibile F 7 tables are over 118 inches long to make sure that the workpiece will be straight every time.
Parallelogram Movement
All SCM Jointers incorporate a parallelogram movement of the infeed and outfeed tables. This system has the table height adjustment through a system of four cams (one per corner of support) that pivot on a radius equal to the head radius. This radiused pivot ensures that the table chip breaker remains in the correct position from the head. Some manufacturers use a wedge type movement which allows the table and chip breaker to move away from the head as it is adjusted for more removal. This system allows splintering and a poor quality finish. The SCM Group parallelogram design and engineering eliminates these issues.
Tersa Monoblock Cutterhead
The cutterhead is made of a single block of steel ensuring complete stability even under heavy dynamic loads. The automatic knives lock into place by means of centrifugal force which ensures safe and precise machining. This system, without fixing screws, makes replacing the knives extremely fast.
Tersa Cutterhead
SCM Group Jointers include the quick change knife heads by "Tersa". This cutterhead eliminates the necessity of gauging the knives each time to ensure proper setting position. The Tersa knives automatically reference into position when the head is turned on. Removal of the knives is as simple as tapping down the wedge blocks and sliding out the knives. Since the knives are two-sided, they can be flipped over, reinserted, and used again.
Additional Overturning Fence
Integrated into the jointer fence, the additional overturning fence ensures operator safety when machining small dimensioned work pieces. This standard accessory provides the operator with increased clearance to handle the workpiece when fully pressed up against the fence.
Cutterhead Guard Planer Protection
Shown here, the standard guard offered on the L’invincibile F 7 is a specially designed European Cutterhead Guard which passes all American safety standards. The guard moves out of position automatically to accommodate your workpiece as it passes underneath the guard for face jointing and also for edge jointing. This guard always covers the unused portion of the knife. Other European style guards require the guard to be manually moved into place when the fence is readjusted or when the workpiece must pass through. When processing thick wood, or edge jointing, this does not cover the blade completely.
Precision that lasts a lifetime without noise with the system on connecting rods. The system guarantees the maximum movement fluidity and avoids deformations of the work table. This guarantees maximum stability, reliability and ergonomics.
Perfect joints every time with concave/convex device. The available settings allow perfect bonding of the pieces giving excellent coupling and eliminating any joint line.
Ergonomics and safety with the "Smart Lifter" protection. The protection system is perfectly integrated into the machine base excluding any hindrance or obstruction in the work, and with automatic vertical, horizontal and tilted movements it provides complete coverage of the tool before, during and after machining.
