Grippex II Small

Product catalog summary

Introduction
The document discusses the use of GRIPPEX® II SMALL, a bar puller designed to enhance the efficiency of CNC-Lathes, particularly in small-batch production. It highlights the advantages of using GRIPPEX for automatic machining, allowing for unmanned production and freeing up time for other tasks.

Specifications and Features
GRIPPEX® II SMALL is a compact and powerful automatic bar puller that can be stationed at the turret and is driven by coolant. It is controlled by the NC-programme and does not require high pressure to operate effectively, working from 0.5 bar onward. The device is capable of clamping very close to the chuck, which minimizes bar overhang and can handle hexagon bars without spindle orientation.

Operational Procedure
The programming method involves several steps: calling the turret tool post holding the GRIPPEX Bar Puller, positioning in X- and Z-axes, turning coolant ON for clamping, unclamping the chuck, pulling out the bar and positioning it in the Z-axis, clamping the chuck, turning coolant OFF for unclamping, and returning to zero to call the first tool.

Advantages
GRIPPEX® II SMALL offers instant setup with secure gripping across its range, is compact and light, and does not require adjacent turret tool positions to be vacated. It can withstand high pressure up to 15 bar without needing a pressure reduction valve.

Performance and Graphical Data
The document includes a pulling force graph that illustrates the maximum allowable weight of a mild steel bar that can be pulled at a coefficient of friction valued at less than 0.2. The graph shows the relationship between coolant pressure and bar weight.

Conclusion
GRIPPEX® II SMALL is presented as an effective solution for improving the productivity of CNC-Lathes by automating the bar pulling process, thus optimizing time and resources in small-batch production environments.

GRIPPEX® II SMALL Powerful Automatic Bar Puller for Small CNC Lathes • STATIONED AT THE TURRET • DRIVEN BY COOLANT • CONTROLLED BY THE NC-PROGRAMME GRIPPEX® II is the Bar Puller that makes your CNC-Lathe more effective, right away! For various reasons, such as high costs or limited floor space in work shops, a small percentage only of the CNC-Lathes are equipped with some kind of magazine-type bar feeder. In small-batch production, however, the machine spindle itself, in addition with its inserted guiding tube and GRIPPEX, provides you with a simple and highly efficient Bar-Feeder. Grippex® II Small, Patent Pending & Design Patent Pending. A new way to work Please, imagine that 40 workpieces of 20 mm length each may be automatically machined from a single one meter bar! - Make GRIPPEX do it for you! 40 workpieces in unmanned production! Supposing that the machining cycle time is 1 minute. Then GRIPPEX gives you 40 spare minutes for better use than pulling the bar manually or handling small pieces of cut raw material. - You’ll find yourself with a lot of spare time for other operation such as quality checks and/or making preparations for the next batch work etc. Grippex advantages Programming method • Calling the turret tool post holding the GRIPPEX Bar Puller. • Positioning of GRIPPEX in X- and Z-axes. • Coolant ON for GRIPPEX clamp. • Chuck unclamp. • Pulling-out the bar and exact positioning in Z-axis according to the programme. • Chuck clamp. • Coolant OFF for GRIPPEX unclamp. • Return to Zero and calling first tool. • Instant setup - gripping is secured without any adjustment within the whole gripping range. • Compact and light - Adjacent turret tool positions need not be vacated • Powerful - stands high pressure - 15 bar. No need for a pressure reduction valve. • Grippex doesn’t need high pressure for pulling properly. • It’s working from 0.5 bar onward (see the power diagram on next page) • Clamps very close to the chuck, allowing for short overhang of the bar. • Clamps hexago
