How can we help you?
Here, you'll find answers to common questions - but if you need more information or have a specific query, please feel free to reach out.
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.
We supply a wide range of 2-jaw, 3-jaw, 4-jaw and 6-jaw chucks, including manual, hydraulic and pneumatic chucks in sizes from small to large.
Hard jaws must be selected according to the exact Kitagawa chuck model and size. Chucks of the same nominal diameter may require different jaw configurations, serrations or mounting dimensions. Always confirm the chuck model before ordering.
If you are unsure, provide Dimac with the chuck model shown on its identification plate and we can confirm the correct hard jaws.
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.
Kitagawa's BR Series is the latest generation of power chucks, designed for high-speed, high-precision workholding with reduced maintenance and automation compatibility.
Hard jaws are hardened and provide a strong,durable grip. They are commonly used for first-operation machining and gripping unmachined material.
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.
Not always. Many Kitagawa chucks and cylinders are compatible across product classes, reducing the need for additional components when upgrading. Compatibility should always be confirmed before installation.
The gripping range depends on the combination of the hard-jaw model and compatible Kitagawa power chuck. Refer to the Grip Range and Configuration links shown on the product page for the relevant chuck series.
If you’re unsure which gripping range applies, contact Dimac with your chuck model and hard-jaw model and we can help confirm the correct configuration.
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.
Absolutely. Kitagawa power chucks are engineered for repeatability and quick-change setups, making them ideal where flexibility and efficiency matter. Kitagawa offer a range of standard and advanced workholding for turning applications.
Bar Gripper Jaws are designed for gripping smaller-diameter bar that standard stepped hard jaws may not accommodate.
View our range of Bar Gripper Jaws or contact Dimac to confirm the correct jaws for your chuck and bar diameter.
Kitagawa recommends greasing the chuck every day. Grease more frequently during high-speed operation or when using large amounts of water-soluble coolant. Dimac stocks and supplies Kitagawa's official recommended CHUCK GREASE PRO white grease. Always follow the maintenance instructions for your chuck model.
Yes, but master jaws should only be replaced by trained personnel. The chuck must be disassembled and inspected, with any damaged, cracked or worn components replaced as required. Contact Dimac Tooling for the correct replacement jaws and servicing advice.
Hard Gripper Jaws allow you to control the workpiece seating depth while retaining the durability and convenience of hardened jaws.
The seating depth can be adjusted in 5mmincrements, or a custom stop can be manufactured when a specific seating depth is required.
Kitagawa recommends disassembling and cleaning the chuck every six months or 100,000 strokes,whichever comes first. For cast machining, clean it every two months. This work should be carried out by trained personnel following the chuck manual.
We require the information in your machine's spindle datasheet to ensure the chuck matches the spindle nose and for a power chuck, the push/pull force of the hydraulic cylinder and the drawtube configuration where relevant. Dimac can match a power chuck to your machine's spindle configuration.
