Chuck operation is slow, not smooth, or the chuck is inoperable. I checked the hydraulic supply and the cylinders, but found no problem. What should I do?

Shut off the hydraulics and the power supply, and clean and grease the chuck.

Do you recommend any grease products?

You should be able to use any pressure-resistant grease commercially available without encountering problems. MATSUMOTO recommends grease that includes about 5% molybdenum disulfide. For more information, please refer to this page.

Where are the lubrication locations?

Supply grease via the grease nipples.

How can I supply grease?

Supply clean grease using a (clean) grease gun, which are commercially available.

Do you recommend any grease guns?

Not in particular. However, a grease gun equipped with a large-diameter port may interfere with the spot facing of the grease nipple. Therefore, using a grease gun with a small-diameter port is recommended.MMK would recommend bite and lever type.MMK power chucks are made with high precision.Because a clearance is so small, grease pressure is high.MMK would recommend bite and lever type.

When should I supply grease?

Supply grease to a MMK power chuck at intervals of 8 operating hours.

How much grease should I supply?

Supply 1-2 cc of grease to one location (one grease nipple) at intervals of 8 operating hours. More frequent lubrication may be needed, depending on the operating condition of the chuck.

How can I check to see whether the lubrication I conducted was appropriate?

Supply grease until it comes out of the clearance of the master jaw. Be sure to remove this excess grease after lubrication. Lubrication in this manner has no ill effect on performance, but can cause some grease to fly-off when the chuck is first rotated after lubrication.

I cleaned and greased the chuck as instructed on your website, but it remains inoperable. What should I do?

Check the relevant devices again. Then disassemble, clean, reassemble, and grease the chuck. For details regarding the overhaul procedure, please refer to the instruction manual.

After performing the steps above, the chuck still does not operate. What should I do?

Consult with your local distributor or send us a message via the Inquiry Form. Please provide the following information when contacting us:
- Model (e.g. chuck ZA6-8-52-31)
- 5- or 6-digit serial number (e.g. 115350)
- Model of the machine on which the chuck is installed
- Operating conditions
(The model and the serial number are marked on the chuck.)

Unfortunately, I have lost the instruction manual and/or tools included with the product. What should I do?

How often should I replace the lubricant for the rotary table? Do you recommend any lubricants?

Lubricant should be replaced at 6-month intervals, though the time interval may be adjusted according to the operating conditions. For information regarding recommended lubricants, please refer to the instruction manual.

The rotary table has not been in service for longer than one year. What action needs to be taken before using the table?

Replace the lubricant. Warm up the table at a low rotating speed for about one hour.

The rotary table suffered an impact (for example, a collision with a tool), and now it does not operate (rotate). What should I do?

Consult with your local distributor or send us a message via the Inquiry Form. Please provide the following information when contacting us:
- Model (e.g. MD323R-**)
- 5- or 6-digit serial number (e.g. 115350)
- Model of the machine on which the rotary table is installed
- Operating conditions

The rotary table suffered an impact (for example, a collision with a tool), and the table still operates (rotates). Is there anything I should do?

Check the machine and the rotary table for any defects. Remove the jigs, etc. after checking that it is safe, and then check the rotary table for any abnormal sounds or vibrations. If any abnormal sounds or vibrations occur, contact your local distributor.
Check the load on the rotary table's servomotor. If the motor is continuously overloaded or the load increases at a particular location along the table's circumference, contact your local distributor.
Gather as much information as possible regarding the accuracy of the rotary table. For example, measure the runout in the radial direction and the deviation of the end face while the table is rotating. Then compare the measurement result with the product inspection data sheet provided to every new rotary table. If there are any abnormalities, consult with your local distributor.
