GRM SERIES Automatic stamping and forming machines GRM 80E GRM 80P

Fully automatic perfection Give your production a kick-start. Take advantage of the strengths of the GRM series. You can produce precision parts from wire and strips as well as complete assemblies even more effectively with the universal machining systems GRM 80E and GRM 80P. These compact machines stand out with their high performance with excellent production quality. The open design allows integration of different processing stages such as punching, bending, assembling, welding, threading, screw insertion, transporting, measuring, etc. Automation knows no bounds! The GRM 80P with its...

GRM 80E Stamping and forming machine Highlights at a glance Universal machining system for radial and linear processing Stable two-point eccentric press with plenty of installation capacity for larger cutting tools Large central aperture for variable central mandrel movements Accessories fully compatible for the whole GRM series Comprehensive control and monitoring functions Easy to use VC1-E control with 15“ touchscreen Standard full encapsulation for operator protection and noise control Excellent price-performance ratio

Press The stable 300 kN two-point eccentric press (max. stroke 16 mm) offers a lot of space for larger cutting tools. There is plenty of space to fit dies up to 540 mm in length (strip widths 80 mm max.). For low cutting pressure a 100 kN two-point eccentric press (12 mm stroke) can be used. Compatibility to units of older machines is ensured. Separate press capacity monitoring is offered as an option for each con-rod. Feed Mechanical standard, traverse and tandem feeds to satisfy the highest requirements for precision and speed. Feedtime reduction offers larger head angles for...

Slide units (GRM 80E/P) Depending on the force required and the space available, cam driven normal, narrow, sub-bed, wide or special design slide units are available with rigid or sprung retraction (max. nominal force 90 kN, max. stroke 95 mm). Optional sensor-based protection of the slide unit guarantees maximum production safety. Standard noise and operator protection The full encapsulation of the machine for noise and operator protection, with two doors at the front and rear, is fully compliant with the current European Machinery Directive 98/37 EU. Noise insulation reaches a maximum of...

GRM 80P Stamping and forming machine Highlights at a glance Powerful machining system for extended range of applications Greater processing room thanks to the spatial division of punching and bending operations More than 1400 mm travel for linear tool applications Flexible integration of all Bihler key technologies Powerful 400 kN two-point eccentric press with large installation capacity for larger cutting tools Two additional drive positions below the press Large central aperture in the work plate for flexible central mandrel movements Compatible with tools of the GRM 50, GRM 80 and GRM...

Feed Standard implementation of the compact NC radial gripper feed RZV 2. The RZV 2 stands out with its fast feed speeds and excellent positioning accuracy (±0.02 mm) - also for large feed lengths. Automatic adjustment for material thicknesses between 0 and 9.5 mm. The shorter feed angle leaves a greater machining angle for optimum cam plate movement. This results in smoother running and higher production speeds. A mechanical feeder unit with feed-time reduction can be installed as an option. GRM 80P Press The 400 kN two-point eccentric press offers plenty of room for cutting tools with...

Separate press module The GRM 80P has a separate press module next to the work plate. The clear separation of punching and forming offers more space for more comprehensive processes. With over 1400 mm travel for linear tool applications a total of more than 2100 mm is available on the work plate, if the press is included. Additional process modules for threading, welding, screw insertion, mounting, laser marking, etc. can be integrated flexibly in different applications. Additional drive positions below the press Two additional drive positions are fitted below the press. Bushings, bending...
