How can we help you?

Chucks wear out over time, even with proper maintenance.

Watch for these signs:

• Higher hydraulic pressure needed to maintain a secure grip.
• Jaw flaring or kicking out when clamping a workpiece.
• Loss of concentricity, even with pre-machined soft jaws.
• Persistent chatter on the workpiece.
• Worn or damaged master jaw serrations.

If you notice any of these, it’s time to service or replace your chuck to keep machining safe and accurate.

Greasing your chuck with the right lubricant, like Kitagawa Chuck Grease Pro White, keeps it performing at its best. Proper lubrication reduces friction, increases grip force by 40–70%, and extends the chuck’s life. This grease resists extreme pressure, coolant washout, and centrifugal forces. Regular greasing ensures a consistent grip, reduces wear, and improves machining efficiency while cutting down maintenance and downtime.

We recommend applying two shots of grease per master jaw at the start of each shift. The amount may vary depending on grip cycles, grip force, materials, and operating conditions. Regular greasing reduces friction, keeps maximum grip force, and improves chuck efficiency while extending its life. Always use the manufacturer-recommended lubricant for the best results.

Yes, we sell master jaws. However, we would recommend replacing the chuck if the master jaws have been damaged, worn or involved in a crash as this can affect your chuck's performance and accuracy.  If unsure our team is happy to help with expert advice.

Workholding must ensure accessibility, rigidity, and repeatability while allowing full tool access. Lang Technik’s Makro-Grip 5-Axis Vice offers strong clamping with pre-stamping technology for secure holding at low pressure. Lang Technik’s Quick-Point System enables rapid, precise workpiece changes, improving efficiency and machining quality.

A stamping unit is crucial for achieving precise, repeatable clamping with minimal effort. It enables quick, secure, and consistent workholding for high-precision parts. Pre-stamping technology eliminates the need to machine a dovetail profile, which is not always required for the workpiece. This reduces setup times, protects parts from deformation, and boosts productivity. Systems like Lang Technik’s Makro-Grip offer reliable clamping with fast changeovers, increasing efficiency in both high-mix and high-volume machining.

Using modular and high-density workholding—such as tombstones, grid plates, and zero-point systems—minimises setup times and boosts spindle uptime. Lang Technik’s Quick-Point System and OK-Vise’s Multi-Rail System streamline job changeovers while maintaining rigidity and precision, allowing for efficient loading of multiple parts and maximising your HMC’s productivity.

Most NC rotary tables come with a 3-jaw chuck. Adding a zero-point system allows fast swaps between a chuck, vice, or trunnion. Lang Technik’s Quick-Point System offers even more flexibility with a through-bore option.

Billets start uniform but often finish non-uniform, making quick workholding changes crucial. A zero-point system enables seamless transitions between vices, chucks, and fixtures, cutting setup times from an hour to minutes. Solutions like Lang Technik’s Quick-Point 96/52 System and Jergens Ball-Lock System boost productivity and efficiency.

Vertical machining centres have large tables, yet standard vices often underutilise space. A flexible workholding system, like OK-Vise’s Multi-Rail, increases clamping force and allows multiple small or large workpieces without constant reconfiguration, maximising table use and efficiency.

A bad smell in coolant is usually caused by anaerobic bacteria that produce sulfur, creating a rotten egg odor. To fix this, use odor control tablets and maintain the right coolant concentration. Zebra Oil Skimmers regular cleaning, good filtration, and chip removal are also key. Clean the sump periodically to prevent recontamination and keep your coolant system in good condition.

The Clean-tech chip fan fits all standard tool holders with a 20mm diameter, except shrink holders. This makes it easy to use with most CNC machines. Ensure your tool holder matches the 20mm diameter for proper clamping and smooth operation. The fan improves chip removal and coolant, helping your equipment run efficiently.

To reduce swarf waste and retain coolant, consider using an Eidos Briquette Press. This press efficiently compacts swarf into solid briquettes, which not only reduces waste but also separates the coolant for reuse. By compacting the swarf, the press helps retain valuable coolant, reducing the need for frequent replacements while minimising waste disposal. This improves overall coolant efficiency, lowers operating costs, and helps maintain a cleaner, more productive workspace.

Reven mist extraction systems capture coolant mist generated during machining and return it to the machine’s coolant reservoir. This process prevents evaporation by filtering and collecting airborne mist and cycling it back into the system. Not only does this reduce coolant loss, but it also improves the work environment by minimising airborne contaminants and mist. By maintaining consistent coolant levels and reducing waste, Reven mist extraction enhances both efficiency and safety.

Yes, we keep critical spare parts in stock for all our coolant and swarf management systems. Many are listed on our product page, where you can check stock levels and prices, including Clean-Tec Spare Kit, Freddy Filter bags, heating elements for the EZvap and replacement skimmers belts. This makes it easy to find what you need and reduce downtime. Our team is always ready to help with any extra parts to keep your equipment running smoothly.
