Seco range of rotating holders allow you to get the most out of both your machine and tool by offering a comprehensive array of solutions to connect them. This diverse portfolio includes Steadyline tooling with built-in vibration damping. The range covers all standard workpiece side connections, as well Seco’s unique connections. Machine side connections are included for most of the norms, including HSK-A-E-T, DIN, BT, ANSI, PSC (Seco-Capto) and Cylindrical.
Seco offers a broad range of shell mill holders based on spigot and tenon drive features according to ISO 3937. Providing excellent results in rough to fine milling applications, this portfolio includes options for most machine side connections, as well as most workpiece side diameters.
Accu Fit holders are fine balanced to 3 g.mm/kg. As the mechanism is self-centering, balance of the assembled cutter and holder is maintained during operation. Not only are they perfectly balanced during high-speed milling, in difficult materials the low runout achieves identical depth of cut for all inserts.
Seco disc mill holders are for holding disc mills (e.g. Seco disc mills type A) by an adjustable sliding shaft arbor equipped with a driving key. This is also known as a ‘telescopic’ disc mill holders. The adjustable sliding shaft arbor allows a wide range of disc mills having different widths to be clamped on the same disc mill holder. The arbor and disc mill are locked onto the holder’s body using the built-in pulling screw. A slim workpiece-side clamping flange permits optimized accessibility.
Seco’s range of side lock holders uses side locking screws to secure the tool shank against the bore of the toolholder and offer anti-pull-out protection. This makes the holders very well suited for heavy machining operations.
Seco shrinkfit holders are the slimmest possible way to hold round tool shanks with high precision and strong clamping forces, all without additional clamping screws or nuts. The bore in which the tool locates is slightly undersized compared to the tool shank. Heating the holder opens up this bore (with specialized heaters e.g. Seco’s EasyShrink® devices), allowing the tool to be inserted. As the holder cools, the bore shrinks 360° around the tool to create a concentric and rigid clamping. This achieves high material-removal rates through increased depths of cut and higher table feeds.
Hydraulic chucks offer high clamping forces and run-out qualities of up to 3µm at 3xD (Standard 3 µm, Strong 4µ, Slim 5µ) which makes them an excellent solution for HSM, rough and fine machining applications.
The EPB 5831, a new slim profile version, even makes it easy to perform semi-finishing and finishing operations in confined spaces such as narrow mould cavities.
Very easy-to-use, the tool is clamped using one single pressurizing screw. An internal piston pressurizes hydraulic fluid into a chamber surrounding the holder bore, uniformly applying high pressure to grip 360° around the tool shank. This holds cutting tools with excellent precision.
Fine balanced as standard, hydraulic chucks can reach rotation speeds up to 40,000 rpm. The stop end screw allows the projection of the tool to be easily set, while reduction sleeves, acting as a split collet, allow the chuck to grip more shank sizes and types, including Weldon and Whistle Notch.
To prolong tool life and enhance precision, the bore has a helical groove where dirt, oil or grease can collect when it has inadvertently been left on the tool shank.
Increase your flexibility with Seco’s Power Milling Chucks, extremely versatile holders that provide high clamping torque and are extremely easy to use. Power Milling Chucks offer run-out qualities of up to 5µm at 3xd and incorporate reduction sleeves that allow multiple tool diameters to be held by a single holder.
Incorporating a nut-and-needle bearing that acts on the small tapered external diameter of the body, Power Milling Chucks are easy and fast to use. Operators simply tighten the nut on the holder until it comes into contact with the body. Power Milling Chucks can be used with all types of tools with cylindrical shanks for both roughing and finishing operations.
Power Milling Chucks are available in two diameters: 20mm and 32mm (0.75" and 1.25"). Available machine side connections include HSK-A, Seco-Capto, Din, Bt, Ansi, Din taper-face, Bt taper-face and Ansi taper-face. Reduction sleeves allow the holders to be used with tools ranging from 6mm to 25mm (0.25" to 1.0").
When used with tools without internal coolant channels, coolant can be delivered to the cutting zone via grooves along the tool shank of the chuck or sleeve. For tools with internal coolant channels, special stop screws can be used to force coolant through the tool.
This system offers significant versatility due to interchangeable collets that cover a large range of tool shank diameters for the same chuck. This technology requires only standard keys without any maintenance on the chuck.
Seco universal drill chucks provide a simple, easy to use solution for holding drills. The compact design is compatible with clockwise and counterclockwise spindle rotation and allows the tool to be changed directly on the machine.
A side-access screw and gear mechanism provide clamping and high clamping force is maintained through the gripping jaws’ large surface contact with the tool shank. For diameters 2 mm and larger, the holders provide a maximum run-out of 40 µm at a gauge projection of 2.5xD.
Seco’s range of tapping chucks offers machined thread results on machines with and without synchronized spindle rotation vs X & Y table axis.
Combimaster is a modular milling cutter system with a wide range of shank types, lengths and interchangeable cutter heads.
The range includes the Steadyline vibration damping holders that automatically counteracts and eliminates tool vibration. This patented solution boosts productivity and process security, and make the Combimaster system ideal in long overhang situations.
With square shoulder and end mills, copy mills, face mills, plunge mills and disc mills included, the system offers maximum flexibility over a wide range of applications. All Combimaster heads and shanks have coolant holes and many of the cutter heads are available in different pitch versions.
The system also includes an ER Collet System for face and side milling operations. Unlike anything else on the market, the system combines ER collets, ER clamping nuts and a ball bearing interface that allows for unmatched tool positioning and tightening during setup. Available in three ER sizes and five different thread-size connections, the system supports a wide range of interchangeable milling cutter heads, especially those in the Turbo line.
Graflex assemblies include arbors, intermediates, toolholders and boring heads that can be rapidly built together when they are needed.
Suitable for milling, drilling, tapping, reaming and boring, Graflex modules offer tooling of variable lengths and diameters and can be fitted on all types of machines simply by substituting the Graflex basic arbor.
Excellent connection rigidity and precision enables Graflex assemblies to be used in similar machining conditions as the same sized Monobloc holders. The wide range of modules permits tooling dimensions closest to the required machining operation for optimized cutting conditions.
All basic arbors, extensions and reducers, main toolholders and all boring heads have through coolant possibilities.
The Seco-Capto™ modular tooling range uses Polygonal Shank Coupling (PSC) in accordance with ISO 26623 and features a self-locking taper joint.
Providing fast and easy tool loading and unloading, the Seco-Capto taper joint can be forced apart by unscrewing the center bolt in the center bolt system or through untightening of the cam in the cam shaft side clamping system. The Seco-Capto range includes basic arbors, intermediates and toolholders and adapters.
For machines not equipped with through-the-spindle coolant, rotary coolant inducers for drills provide a means of delivering coolant through the drill. These inducers are available with Graflex back-ends in size 5 or 6 and in five types of front-ends.
Front-end options include: Type BSM/6181-6183 for Type 7 drill shanks, ISO 9766 (Weldon compatible); Type BSM/6100-6101 for Perfomax drills with Type 7 shanks, adjustable +0.8 to -0.3 mm on diameter; and Type BSM/401: for Graflex modular system modules. Inducers are available for manual and automatic tool changers.
Seco taper adapters allow the use of holders or tools with a different machine-side taper then the machine spindle taper, such as using a BT40 tapping chuck on a 50-taper spindle.
These adapters eliminate lead time losses in the event of a machine breakdown. Adapters can also help in testing custom tools on another machine than the planned production machine.
Taper adapters avoid the need for a supply of new holders or tools for a specific machine. They arrive ready to use with built-in locked clamping mechanisms featuring a clamping screw on a ball bearing for steep taper clamping or HSK locking unit for HSK-A or HSK-C taper clamping.
These Seco holders and adapters are for mounting bridge bars on machine spindles. HSK and SA holders are available, as well as Graflex™ modular adapters for long assemblies. Angular positioning of the bridge every 30° allows easy positioning in machine magazines.
Seco’s prepared blanks allow customers to produce their own custom tooling solutions. The machine-side connection is 100% machined. The workpiece side consists of a “soft”, non-hardened cylinder (120 to 130 daN/mm² tensile strength) permitting easy machining. Subsequent heat treatment is not recommended.
Seco test bars are primarily used for checking accuracy and to set the axes of the machine tool and tool presetter. Direct run-out between front part and taper is 5 μm maximum. Measurement values are tabulated on the accompanying data sheet and certificate of accuracy. Values and positions for diameter and length measurements are laser engraved on each test bar. The front leading edge can be used for optical presetting. Seco test bars are delivered in a protective case.
