OK-VISE rotary columns are made of aluminium and they come with steel made corner clamps. They work as a trunion unit between indexer and a tail support. This new system makes efficient use of machinable area a reality, ultimately leading to savings in tool changes, less operator interventions and extended cycle times. Most important feature is a possibility to use subplates resulting to a remarkable cut down in machine stop times which is critical especially in the vertical machining centers.
Parts fixturing probably represents the best value in today´s metalworking technology, if you calculate the cost of a CNC machine tool, the cutting tools, tool-holders and tool-changer with both the programming and the design software and compare these investments to the cost of your workholding equipment. Fixturing normally costs only a fraction of the amount the others cost. Yet, the potential for time savings and process improvements offered by a good fixturing solution are substantial.

The Multiflex series vises are a total new concept of modular clamping system able to maximize the machine table capacity and increase its productivity (reduced dead times).
This system is designated for clamping several workpieces at the same time on the machine tool table, thus reducing tool changeover times.
This modular system makes a wide variety of clamping arrangements possible, wheter for several workpieces (equal or different) or for custom application. The base could in fact be clamped to the machine table while the jaws positioning, number or type could vary according to workholding needs (from 1 to 9 pcs. clamping possibility on the same vise base, see page 6-26).
1. Made of high alloyed quality steel, hardness 60±2 HRC - No wear
2. Highest precision accuracy: ground rack teeth on both the base and the jaws (ground teeth even between the fixed and movable jaws)
3. Minimum of set up times: quick and flexible jaws positioning
4. Possibility of vises matching and jaws alignement on whatever position on the vise base
5. Unlimited clamping range and combination (step jaws, prismatic, soft)
6. Guided Pull Down jaw Action thanks to the ground comb-teeth jaws
7. Possibility of vertical set up through Tombstones or Solid Vise Cube |

Precision and modularity united to an exceptional price-quality relationship assured the GERARDI Co. success, the company has become in few years the Europe leader in the modular vises manufacturing. GERARDI new thinking has made others manufacturers to produce copies, but there is no other manufacturer with such a broad program or which has developed such a complete BLOCKING MODULAR SYSTEM thinking. It will always pay to invest in the original product.
Often the positioning accuracy and the set up fastness seem to be two non-compatible characteristic, but not at all with GERARDI system: the built in, fixed reference points give both precision and short set up times: moreover the broadest assortment program available allows you to obtain with standard solutions even the fixtures you thought special.
Following is a synthesis of the GERARDI vises program:
STANDARD and XL vises, which you can choose in 6 different types of sizes each with several openings, even in the version with narrow-width ground jaws (to work with the vise positioned on its side) or with super-narrow jaws (to match vises side by side).
All the vises can be mounted on the swivel base which you can buy even in a second time as all the other combinations (extra modular elements as extensions and stack-type jaws, pull-down jaws, floating jaws, prismatic, for round pieces, solid with single or double step, soft or case hardened, with adjustable set screws, hydraulic-control, etc.). |

ARNOLD SC high precision vices are compact, high and self-centring and maintain constant length, which makes them especially valid for working in 5- axis machining centres.
Self-centring high precision vices.
Accuracy of 0.01mm on the repeatability of clamping.
0.03 mm accuracy on centring.
Designed to work on machining centres with small tables and in 5-axis controlled centres.
Compact design with exterior guides that avoids deformation as the clamping force is distributed throughout the width.
Clamping force from 2 to 4 tons, in accordance with the clamping torque applied.Threaded right-left spindle, which can be operated with standard key.
These vices have a clamp casing system.The force is applied as near as possible to the piece to be machined. This means that the torque power is used to the full.
Interchangeable jaws can reach a height of 125mm, this means they can overcome the biggest obstacle for this type of work; avoiding collisions with the machine turrets or the rotation of the table. |
