SMW-AUTOBLOK Chucks, Steady Rests and Workholding Systems

Source SMW-AUTOBLOK workholding for lathes and machining centers, including chucks, steady rests, cylinders, collets and positioning systems. Define the equipment package around your technical requirements.

KNCS-2G power chucks

KNCS-2G power chucks combine quick jaw changes with a sealed body that protects the mechanism from dust and swarf. Specify the complete chuck designation, spindle mounting and installed cylinder when requesting a replacement chuck or spare parts.

KLU, SR and SLU self-centering steady rests

Steady rests support workpieces during turning and grinding. KLU uses narrow arms for crankshaft applications, while SR and SLU offer different configurations. Replacement selection requires the clamping range, cylinder arrangement and mounting dimensions.

KLU is a Premium line steady rest with narrow arms
SR includes a sealed body and a chip guard with coolant nozzles
SLU belongs to the Basic line
Check position monitoring and lubrication for the selected version

SIN-S and VNK-T2 actuating cylinders

Rotating hydraulic cylinders actuate the chuck clamping mechanism. SIN-S is a closed-center cylinder with a central media passage; VNK-T2 has an open center. Check stroke, force, mounting and position monitoring when selecting a replacement.

SIN-S is a closed-center rotating hydraulic cylinder
VNK-T2 is an open-center rotating hydraulic cylinder
Stroke monitoring uses proximity switches or a linear positioning system
LPS 4.0 is a position sensor, not a cylinder series

COMOT collet chucks and EMX mandrels

Collet chucks grip an external surface, while expanding mandrels locate inside a bore. SMW-AUTOBLOK offers COMOT, KSZ-MB and EMX systems. Choose the arrangement from the component datum, geometry and machining sequence.

COMOT uses vulcanized collets
KSZ-MB is designed for bar machining with DIN 6343 collets
EMX-P and EMX-F/FP are power-operated expanding mandrels
EMX-FP provides a pull-down function

SLX digit vises and APS, WPS systems

Stationary workholding includes SLX digit hydraulic vises and APS, WPS zero-point systems. Include the table layout, fixture dimensions and attachment points in your request. Existing installations also require module and mating-component designations.

Replacement jaws and chuck accessories

Jaw selection requires the connection type, serration pitch and fastening dimensions as well as the chuck diameter. The catalog covers soft and hard jaws, serrated and tongue-and-groove interfaces, T-nuts and special workholding accessories.

Soft and hard top jaws
Metric and inch serration options
Tongue-and-groove jaw connections
T-nuts and jaws for quick-change systems

CC e-motion automation and F180 coupling

The CC e-motion electric chuck uses independently driven jaws. The F180 inductive coupler transfers energy and data between moving and stationary components. Integration requires the machine control diagram and a list of monitored signals.

CC e-motion is an electric four-jaw chuck
Each jaw has independent drive and monitoring
F180 transfers energy and data without physical contact
Select the coupler version and interface from its documentation

Identify the installed workholding

Start with a photograph of the nameplate and an overall view of the assembly. Copy the full designation, including any suffixes. Add the machine make and model, the installation location and the quantity required. Photograph each nameplate when the chuck, cylinder and sensor carry separate identification.

For a removed component, show both sides and include a scale where useful. State which part needs replacement and which components remain on the machine. An assembly drawing or the technical part of a previous order can help connect the visible marking with the correct configuration.

Specify a replacement power chuck

A chuck request should include its outside diameter, jaw count, spindle connection and required bar passage. Attach the spindle nose drawing or the adapter flange details. For an existing machine, also identify the actuating cylinder and the drawtube or drawbar connecting it to the chuck.

Describe the workpiece and whether it is gripped on an outside diameter, inside a bore or on a special feature. A dimensioned sketch helps define the package and tool access. List the chuck and installation components separately so that the requested supply scope can be checked.

Choose jaws for an existing chuck

Photograph the chuck marking and any identification on the jaw. Show the serration or tongue-and-groove interface, bolt holes and seating surfaces. If identification is missing, include the jaw width, height and length, hole spacing and the interface pitch stated in the equipment documentation.

Specify whether you need soft jaws for machining or hard jaws for a finished gripping surface. State whether the request is for one jaw, a complete set or a set with fasteners. Special gripping profiles require a workpiece drawing and details of the existing fixture.

Prepare a steady-rest replacement request

Provide the complete steady-rest designation, workpiece diameter range and mounting drawing. Identify the cylinder position and loading direction. A photograph inside the machine should show the support, adjacent assemblies and the space available when the arms are open.

Separate a complete steady rest from replacement rollers, arms, lubrication components or position sensors in the request. For a roller, include its marking, dimensions and mounting detail. If the workpiece or machining operation is changing, describe that change before selecting the replacement configuration.

Separate cylinder and position-sensor data

SIN-S and VNK-T2 are hydraulic cylinders, while LPS 4.0 measures position. List the mechanical actuator, sensor, bracket and connecting components as separate items. Include the cylinder nameplate and sensor identification rather than using one component name for the complete assembly.

Provide the stroke, existing hydraulic-system settings and mounting dimensions from the machine documentation. For an open-center cylinder, specify the required bore. A sensor-only replacement also needs its version, connector and mating-component details. Installation settings must follow the documentation for the actual equipment.

Select external or internal gripping

Begin with the workpiece locating surface. External clamping needs the gripping diameter and available length; an expanding mandrel needs the bore dimensions, insertion depth and end-stop position. Include a drawing with tolerances, particularly for thin walls or a restricted gripping area.

State whether the material is bar-fed or loaded as separate pieces and identify the surfaces machined in one setup. For an existing system, provide chuck, collet and adapter markings. Keep a replacement collet request separate from a request for an entirely new workholding package.

Check a zero-point mounting interface

For APS or WPS, provide the module layout on the table or base plate and identify the modules and mounting elements. Include pallet dimensions, fixture attachment points and the required tool approach. Use photographs for the overall arrangement and drawings for dimensioned interfaces.

List modules, pallets, clamping pins and adapters individually when several items are required. Describe manual or automated loading and the available actuation. For a retrofit, identify the components that will remain in service. A shared system name does not establish interchangeability between every version.

Prepare the automation interface

An electric chuck or an inductive coupler requires more than mechanical dimensions. Provide the machine control diagram, the signal list and identification of the installed components. State whether the project is a new integration, a single-component replacement or repair of an existing arrangement.

For F180, distinguish the stationary base from the moving remote unit and check the complete version and data interface. For CC e-motion, describe the gripping operation and required jaw sequence. Keep component supply separate from programming, installation and machine-control commissioning in the project scope.

Order from an assembly drawing

When a part number is unavailable, attach the assembly drawing and mark the required item. Retain the document title, assembly designation and revision information. A cropped image without that context may describe a different version of a similar-looking chuck or steady rest.

For multiple parts, list the drawing item numbers, quantities and short descriptions. Identify parts that work together and should be supplied as a set. Photographs of mating surfaces can help clarify a wear-related request; the repair decision itself requires inspection of the equipment.

Define a complete package or a spare part

Define the supply boundary before comparing quotations. The chuck, jaws, flange, drawtube, cylinder and sensor may be required together or as separate components. For a complete installation, list everything expected on the machine. For a spare part, identify the assembly that remains in use.

The same chuck name can appear in packages with different accessories. Compare fasteners, mating components and additional equipment against the agreed list. If some parts have already been purchased, provide their designations before selecting the missing items, so that the complete arrangement can be reviewed.

Build a clear quotation list

For each line, provide the manufacturer, complete designation, quantity and purpose. Keep cylinders, jaws and sensors with different part numbers on separate lines. If the request comes from an earlier quotation, attach its technical section and indicate which items are still required.

A drawing item number beside the designation helps connect the list with the attachments. Add a technical contact and delivery destination. When several configurations are being considered, identify the preferred one and explain which interface or operating requirement determines the selection.

Photographs that support identification

Include an overall assembly view, a readable nameplate image and close-ups of the connections. Avoid reflections on identification plates. Show both sides of a chuck where accessible, the arms and cylinder arrangement of a steady rest, and the connector and cable markings of a sensor.

Place a scale in the same plane as the measured surface. Use a drawing for complex fits instead of estimating dimensions from perspective photographs. Do not dismantle working equipment only to obtain an image; start with accessible markings and the available technical documentation.

Review changes to a previous configuration

If documents show different designations for the same item, include both and identify where each was found. The document revision, assembly version and installed component all matter. Matching a family name does not confirm matching dimensions, connections or included accessories.

First record the required mechanical and electrical interfaces. Then compare a proposed replacement with the components that remain on the machine. Changes to mounting, control or the working sequence should be recorded in the technical agreement, rather than treated as a simple part-name substitution.

Prepare receiving and installation checks

Before ordering, agree the component list and the designations to be checked at receipt. For an assembly, include its principal accessories; for spare parts, specify quantities by item. Keep the accepted list together with the technical attachments used to define it.

On receipt, compare the markings and delivered contents with the documents and inspect the packaging and accessible surfaces. Pass the technical materials to the machine maintenance specialist before installation. Check interfaces, movement direction and actuator settings using the documentation for the specific equipment.

Describe a new machining application

If no product designation has been selected, start with the workpiece drawing and machining operation. Identify material, dimensions, locating surfaces and the areas to be machined. Add the machine model, work envelope and loading method so that the proposed workholding has a defined application.

Explain tool-access restrictions, adjacent fixtures and any need to relocate the component. For multiple operations, provide the setup sequence. These details support technical clarification and a component list for subsequent review and quotation, without assuming that a generic family description establishes application suitability.

Configuration, compatibility and documentation are confirmed for the specific item. Pricing, lead time and international delivery terms are agreed during quotation. We do not claim official dealer status for the manufacturer.
