A lowpressure, high-pressure hydraulic press drive is energy efficient. LVD’s Energy Reduction System (ERS) regulates the hydraulic pump and motor to lower energy consumption.
The hydraulic drive also reduces noise and shock to increase machine longevity and reduce tool wear.
INNOVATIVE USER INTERFACE
An innovative user interface provides graphic tool images to aid with selections, making entering tool information easier than ever before. Operators interact with a single graphic screen. No tool measurements or electronic adjustments are necessary for routine tooling applications. The operator simply selects the tool to be used – punching, forming, wheel tool, scribing, marking or tapping – and the control software automatically determines the correct stroke settings. No further input is required.
LVD’s hydraulic ram also offers the flexibility of electronic adjustments and features that take advantage of the intuitive control interaction. Users can apply custom settings or alterations to stroke elements such as depth offset, dwell and ram speed, to further maximize machine capabilities.
Patented Smart Stroke® programming maximizes productivity by automatically calculating the optimum hover height for every stroke of the ram.
PROGRAMMABLE RAM MODES INCLUDE:
Standard Smart Stroke – The tool is kept close to the material on short table moves. As hits move farther apart, the software automatically increases the ram hover height to provide clearance for sheet warpage.
The Smart Stroke system also allows the machine to run mechanical machine programs with no need to edit traditional nibble routines or input hover height commands.
Forming – A dwell can be programmed at the bottom of the stroke, allowing the material to flow more completely into the desired shape, minimizing springback and improving the quality of the formed part.
Quiet Punch – The tool is programmed to rapidly approach the material, then slow to enter the material, continuing until shearing is complete. Once breakthrough occurs, the ram completes its cycle at rapid speed. This process reduces noise and shock while maintaining productivity
Strippit M-Series punch presses feature a large 47-station turret configuration that offers tremendous flexibility and capacity. This versatile turret design allows every station to accept shaped punches and dies, reducing setup time.
The Strippit M-Series turret is gear-driven from the outer diameter for smooth, precise motion. Shot pin assemblies are also mounted beyond the punch and die locations to optimize alignment at the tool during the punch cycle.
Self-stripping tooling uses the punch guide to firmly press the material down on the die. The guide continues to hold the sheet against the die until the punch has retracted into the guide, preventing distortion of even the thinnest materials. The end result is flat parts with virtually burrfree holes, greater finished part accuracy and increased machine productivity.
Turret capacity can be easily expanded through the use of indexable Multi-Tools
Large tool change door allows easy access to the turret for quick tool loading. Quick change die holders further reduce turret set-up time.
Ability to punch at any location on the sheet using any turret station within the nominal sheet size reduces repositioning and maximizes productivity.
Joystick mounted near the tool load door provides easy, convenient rotation of the turret for tool changing
THREE STANDARD AUTO-INDEX STATIONS
Strippit M-Series punch presses are equipped with three “D” size geardriven auto-index stations that are a full 88,9 mm. These programmable stations make it possible to punch shapes at any angle to increase flexibility and improve finished part quality.
Large auto-index stations accept a variety of indexable Multi-Tools, further enhancing turret capacity and flexibility while reducing setup time.
ENHANCED FORMING CAPABILITIES
Strippit M-Series machines provide expanded forming capability with a full 25 mm feed clearance between the upper and lower turret. This generous feed clearance allows for the production of higher forms such as lances, louvers, embossments or card-guides.
Strippit M-Series turrets are designed for superior precision. Hardened steel guide bushings provide accurate punch and die alignment and are keyed to accept shapes in every station. Bushings can be quickly and easily replaced by the machine operator, eliminating the need for costly remachining of the turret.
Hardened outboard shot pins provide precise alignment of punch and die for exceptional hole quality.
Gear-driven turret design ensures fast, precise indexing
Bi-directional turret rotation automatically selects the shortest possible route to the next punching station for fast station-to-station positioning and increased productivity.
To meet high-performance fabricating requirements, Strippit M-Series machines can accommodate the latest adjustable thick turret style tooling. Advanced tooling technology provides:
Reduced set-up time
Long tool life
Quick and precise tool length adjustment
Low maintenance costs

Multi-Tool dramatically boosts turret capacity. Once tools are loaded into the holder, Multi-Tool remains in the turret, reducing set-up time. Multi-Tool reduces set-up time by 75% compared to individual punch and die set-up.
Subsequent tool selection by program is completed in less than one second. Standard on Strippit M-Series punch presses, the Multi-Tool indexing mechanism allows each station within the Multi-Tool to be automatically indexed, eliminating the need for specially keyed punches and dies, and allowing indexing of a greater range of commonly used tools. Strippit M-Series punch presses accept 3- or 8-station Multi-Tool configurations.
Form tooling increases machine utilization and reduces secondary operations. The hydraulic ram improves forming operations. Precise programmable ram control minimizes part springback and produces an exceptionally accurate formed part.
Strippit M-Series machines have the flexibility to use wheel-tool technology to rollcut and rollform for quick and efficient cutting and/or forming of straight or curved shapes without nibbling. LVD CNC turret punch presses also employ part marking technology for part or sheet marking requirements and can utilize tapping tools.
