Precision Workholding for Machining & Production

A vice does more than stop a workpiece moving. On a milling machine or machining centre, where the component is held, how it is clamped & how much of it remains accessible can shape the entire machining setup.

Röhm vices & clamping systems give machinists, toolrooms, production facilities & engineering workshops purpose-built workholding options for milling, drilling, CNC machining, repeat production plus multi-sided machining. From conventional machine vices through to NC-Compact & self-centring systems, the right choice starts with the workpiece, machine envelope plus operation—not simply jaw width.

For workshops building a broader workholding setup, Clamps & Vises provides a directly related clamping pathway, while Measuring & Layout Tools support workpiece checks, setup plus dimensional verification. Industrial Shed also carries other Röhm workholding products for machining applications beyond machine vices.

What Are Röhm Vices & Clamping Systems?

Röhm vices & clamping systems are workholding devices designed to secure components for machining, drilling, milling, inspection plus production operations.

Depending on the system, Röhm vice families include:

► NC-Compact vices
► Self-centring vices
► Twin vices
► 5-axis clamping systems
► Conventional machine vices
► Side-mountable machine vices
► Multiple-workpiece clamping systems
► Vice jaws plus supporting components

The important difference is not merely size.

One vice may locate the workpiece against a fixed jaw. Another moves both jaws towards the centre. A twin vice can be configured around two workpiece stations. A compact 5-axis system prioritises access around more of the component.

Those differences directly affect how the workpiece sits in relation to the machine plus cutting tool.

Why Choose Röhm Vices & Clamping Systems?

Start with the machining operation—not the vice catalogue.

Imagine two jobs.

The first is a straightforward milled component where repeatable location against a fixed jaw is desirable.

The second needs tool access around several faces with minimal workholding interference.

Both need secure clamping, but they do not necessarily need the same style of vice.

Röhm offers machine-workholding configurations for requirements including:

► Fixed-jaw clamping
► Centric workpiece clamping
► Single-workpiece machining
► Two-station clamping
► 5-axis machining
► One-off components
► Repeat production
► CNC machining centres
► Conventional machine tools

The better selection comes from matching the clamping principle to the actual component plus machining sequence.

For workshops where machine vices sit alongside general bench clamping equipment, Bench Vice provides another direct pathway for holding components during fitting, preparation plus non-machining workshop tasks.

Common Applications

CNC milling
Machine vices provide a controlled way to locate plus secure components for repeatable milling operations.

Machining centres
Compact workholding can help balance clamping capability with access for cutters, holders plus machine movements.

5-axis machining
Workpiece accessibility becomes especially important when the tool needs to approach the component from several directions.

Batch production
Repeat jobs benefit from a defined workholding arrangement that allows the operator to reproduce the setup across multiple components.

Toolrooms
One-off tooling, prototypes, repair parts plus fixture components often demand flexible workholding rather than one dedicated production fixture.

Maintenance machining
Repair workshops can encounter shafts, blocks, brackets plus irregular components requiring different jaw positions or clamping approaches.

Drilling operations
Suitable machine vices can secure workpieces during drilling where controlled positioning plus workpiece restraint are required.

When parts need preparation, deburring or inspection away from the machine, Workstations & Workbenches provide a dedicated area for supporting workshop tasks.

Product Selection Guide

A useful vice comparison starts with four questions:

What are you machining? Where must it locate? Which faces need tool access? How will the operator repeat the setup?

Choose the Clamping Principle

A fixed-jaw arrangement locates the workpiece differently from a centring vice.

With applicable fixed-jaw systems, one jaw provides the reference while the opposing jaw closes onto the workpiece.

With a self-centring configuration, the jaw movement is designed around centric clamping.

Neither principle is automatically better for every job.

The machining strategy determines which is more appropriate.

Check Workpiece Size & Opening

Do not select by jaw width alone.

Consider:

► Workpiece width
► Workpiece height
► Required opening
► Jaw configuration
► Clamping range
► Available machine space
► Cutter access
► Required mounting orientation

A vice can have sufficient nominal capacity yet still create an awkward machining setup if the workpiece position restricts tool access.

Consider the Machine Envelope

On a machining centre, every millimetre occupied by the workholding becomes part of the setup.

Check:

► Vice body dimensions
► Machine-table space
► Spindle clearance
► Toolholder clearance
► Axis travel
► Workpiece overhang
► Fixture position
► Access for loading plus unloading

This becomes particularly important for multi-axis work where the component plus workholding may rotate relative to the spindle.

Compare Jaw Configuration

Jaw design influences how the component is contacted plus positioned.

Depending on the applicable vice, the setup may use stepped jaws, standard clamping jaws, carrier jaws or other purpose-matched arrangements.

Before choosing jaws, consider the workpiece geometry plus where clamping contact can occur without obstructing machining.

Think Beyond the First Operation

A vice can hold the component perfectly for operation one yet make operation two unnecessarily difficult.

Map the machining sequence before finalising the workholding.

Ask:

► Will the component need to be reclamped?
► Which surfaces become references later?
► Can more faces be machined in one setup?
► Will jaw position obstruct a cutter?
► How will the next operator reproduce the setup?

For dimensional checks during setup, Calipers (Digital / Manual) provide a practical option for suitable workshop measurements.

Which Röhm Clamping System Fits the Machining Job?

The objective is not to buy the most complex workholding system.

It is to use the simplest suitable clamping arrangement that supports the machining process.

Fixed-Jaw or Self-Centring?

This distinction can change the entire setup.

A fixed-jaw vice provides a defined stationary reference side. That can be useful where the machining process is established around locating the component against a consistent jaw position.

A self-centring vice approaches the problem differently by moving the jaws around the workpiece centre.

Consider self-centring workholding when the process benefits from maintaining the component around a central position, but always check the actual vice configuration plus machining requirement.

Röhm's NCZ plus RKZ families are examples of centric-clamping concepts within its broader vice range.

Where the machining operation depends on verifying machine or component position, Alignment Tools (Laser, Dial, Manual) provide a relevant pathway for setup plus machine-maintenance work.

NC-Compact Vices for Machining Centres

Röhm's NC-Compact range is built around machining-centre workholding, with different configurations serving different production requirements.

The RKE family uses fixed-jaw clamping. Depending on the applicable version, the system can incorporate different actuation, clamping plus construction arrangements suited to machine-tool workholding.

Features can vary by model, so compare the individual vice rather than assuming every NC-Compact configuration is identical.

Relevant considerations can include:

► Compact workholding design
► Fixed-jaw positioning
► Guide surfaces
► Chip protection
► Lubrication provisions
► Clamping-force control
► Mounting orientation
► Jaw configuration

The RKE-LV is configured around 5-side machining, where reducing workholding interference can improve access around the component.

That distinction matters because “NC vice” describes a category—not one universal setup.

For workshops also cutting, preparing or finishing metal components before or after machining, Metal Cutting & Grinding Tools provides a complementary pathway into metalworking equipment.

Workpiece Access: The Dimension Buyers Sometimes Miss

Opening capacity is easy to compare.

Accessibility is easier to overlook.

Suppose a workpiece fits comfortably between the jaws but the vice body prevents a cutter from reaching a lower side feature. The vice technically holds the component, yet the workholding still creates another setup.

For multi-face machining, consider:

► Height of the workpiece above the vice
► Jaw contact position
► Vice body interference
► Cutter diameter
► Toolholder clearance
► Spindle approach
► Axis rotation
► Required second-operation access

This is one reason compact plus 5-axis-oriented clamping systems exist.

For workshops keeping machines, vices plus surrounding equipment organised between production runs, Tools Storage & Organization supports storage of tooling, setup equipment plus workshop accessories.

Expert Tips

Draw the workpiece before choosing the vice.
Mark the surfaces that need machining plus the areas available for clamping. This quickly exposes potential interference.

Treat jaw width as one specification—not the specification.
Opening, workpiece height, machine clearance plus clamping principle can be equally important.

Plan the second operation before starting the first.
A small change in initial workholding can sometimes simplify later setups.

Keep the locating surfaces clean.
Chips between the workpiece, jaws or reference surfaces can compromise the setup before machining even begins.

Check cutter access with the actual toolholder in mind.
A cutter may reach the feature while the holder, spindle nose or machine movement cannot.

Record proven setups.
For repeat work, document vice model, jaw arrangement, workpiece position plus relevant setup measurements.

Do not automatically increase clamping force.
Workpiece geometry, material plus wall thickness matter. Excessive force can be inappropriate for deformation-sensitive components.

Inspect jaws as working components.
Damage, contamination or unsuitable jaw contact can affect how a component sits in the vice.

Routine cleaning around workholding equipment is easier when chips plus contamination are addressed before they accumulate. Tool Maintenance Kit provides a practical maintenance pathway for workshop equipment plus tooling.

Complex machining also depends heavily on the practical knowledge of the person designing the setup. Whispers & Wisdom: Master Tradesperson explores why experienced trade knowledge remains valuable as tools plus equipment become more capable.
