Machine Vices

About Machine Vices

Machine vices, also known as cross vices or drill press vices, are essential precision workholding tools designed to secure workpieces firmly during machining operations. These robust devices mount directly onto machine tables, pillar drills, milling machines, and bench grinders, providing stable clamping that ensures accuracy and safety during drilling, milling, grinding, and other metalworking tasks. MyToolShed.co.uk supplies professional-grade machine vices built to withstand the demanding requirements of workshops and manufacturing environments.

Unlike standard bench vices, machine vices feature sliding bases with cross-feed adjustment mechanisms that allow precise positioning of the workpiece in multiple directions without repositioning the vice itself. This capability makes them invaluable for repetitive operations and achieving exact measurements. The range at MyToolShed includes heavy-duty models from trusted manufacturers like Sealey, engineered with hardened steel construction and precision-ground surfaces to deliver lasting performance in professional settings.

Applications

Machine vices are indispensable tools across numerous trades and industries:

• Engineers and machinists – precision drilling, milling operations, and metalworking tasks
• Tool and die makers – accurate positioning during fabrication and modification work
• Manufacturing facilities – production line workholding and quality control operations
• Maintenance workshops – component repair and modification tasks
• Educational institutions – technical colleges and apprenticeship training programmes
• Model makers and hobbyists – detailed metalwork requiring precision clamping
• Fabricators and welders – preparation and finishing of metal components

Choosing The Right Machine Vices

When selecting machine vices from MyToolShed.co.uk, consider these key factors:

Jaw width and opening capacity – Choose dimensions that accommodate your typical workpiece sizes. Common jaw widths range from 50mm to 150mm, with opening capacities varying accordingly.

Construction quality – Look for hardened steel bodies with precision-ground surfaces and robust slide mechanisms. Cast iron construction offers good stability, whilst steel versions provide superior durability for heavy-duty applications.

Travel distance – The cross-slide travel determines how far you can move the workpiece without manually repositioning the vice. Greater travel distances improve efficiency for complex operations.

Mounting method – Verify the vice base matches your machine table configuration. T-slot mounting options provide maximum stability for larger machines.

Jaw type – Serrated jaws offer excellent grip on raw materials, whilst smooth jaws prevent marking on finished surfaces. Reversible jaws provide versatility for different applications.

Frequently Asked Questions

What's the difference between a machine vice and a bench vice?

Machine vices are specifically designed for mounting on machine tools like drill presses and milling machines, featuring cross-feed adjustment mechanisms for precise positioning. Bench vices mount to workbenches and lack the sliding base functionality required for machining operations.

Can I use a machine vice on a pillar drill?

Absolutely. Machine vices are ideal for pillar drills, providing secure workpiece clamping and precise positioning that significantly improves drilling accuracy and safety compared to hand-holding materials.

How do I maintain my machine vice?

Keep slide mechanisms clean and lightly lubricated with appropriate machine oil. Remove swarf and debris after each use, check jaw alignment periodically, and ensure mounting bolts remain tight to maintain accuracy and longevity.
