FAQ (Sfida)

A. It is applied to DIN6499 and/or DIN6499-B.

A. It is applied to DIN6499 and/or DIN6499-B.

A. 19.6N・m

A. From φ1.0 to φ6.0mm (Collet size under φ1.0 from φ0.2 is available upon request).

A. Please put clamp nut on the tip of spindle and rotate to the left with accessory spanner until the SENTAN TOOL is removed.

A. It is suitable for polishing, deburring, drilling, grooving, cutting, etc. The spindle can be mounted on machining center, NC lathe, board dividing machine, specialized machine, etc.

A. It depends on user environment. Please judge by observing its condition.

A. Spare spindle is to be supplied by our customers.

A. We support you as same as we do for Minimo series.

A. Because the load against spindle is different in each environment and work condition, we do not set any warranty period.

Q. Are SFIDA series RoHS compatible?

A. Yes, they are RoHS compatible.

Q. I would like you to repair my SFIDA.

A. We can repair SFIDA as same as we do for Minimo series.

Q. How strong is a cord?

A. The cord itself passed 50,000 times of bending test and cord clamp passed 250,000 times of the test.

Q. Is the cord clamp waterproof?

A. It is compatible with IP67.

Q. Where is the recommended clamping area to hold the spindle to mount on?

A. Please clamp the spindle on ideally center area of recommended clamping area on catalog and use wide holding tool.

Q. How much is the recommended tightening torque of spindle?

A. Tightening torque of spindle depends on its shape, accuracy, etc. Please set the torque value with enough

Q. What kind of mounting holder do you recommend?

A. Please refer to Minimo general catalog.

Q. How heavy is MS01?

A. It is approximately 680g.

Q. How much is the overhang amount of SENTAN TOOL?

A. Please use under recommended condition of tools.

Q. Can I use cutting oil at machining? Can I use water-soluble cutting fluid?

A. The cooling air is served as air purge of tip part. Cutting oil and chips are hardly infiltrated if air keeps flowing. Please do not blow a part between rotation plate on the front and gap on the body directly by using air gun and others.

Q. What is the unit continuous field? What level exactly can I process?

A. Please test processing with observing the load level meter by customer yourself and refer to the manual for level range.

Q. How much is the rotation deflection accuracy?

A. Deflection accuracy of tapered part on main shaft is less than 1μm. Standard Collet Chuck: In case of φ3mm tool, 15μm at 16mm from collet chuck. Ultra-Precision Collet Chuck: In case of φ3mm tool, 10μm at 16mm from collet chuck.

Q. How much is the axial elongation of rotating shaft?

A. It depends on rotation speed, but it should be about 1μm if the spindle run in before processing.

Q. How long does it take to make rise in temperature stable?

A. About 10 minutes no-load running makes spindle stable in any rotation speed, and please run spindle with no-load condition before the precision processing.

Q. How many degrees are acceptable on outer cylinder?

A. It is acceptable if the temperature of outer cylinder is within ±20℃ comparing with ambient temperature and the temperature of outer cylinder is lower than 50℃.

Q. Which bearing do you apply?

A. We adopt ceramic bearings and angular bearing for main shaft

Q. Do you have other types of SFIDA than BT type?

A. Yes, we have, but they are based on order production. Please refer to our Minimo general catalog for details.

Q. How long is the insertion depth of SENTAN TOOL?

A. It is approximately 40mm from collet chuck in main shaft.

Q. Do I need warming up operation?

A. Please rotate spindle from low to maximum speed in 15 to 20 minutes by gradation at the first time of operation and if the spindle has not been used for a long period of time and also confirm that the spindle has any abnormal heat, noise and vibration. * It should be OK if the temperature on outer cylinder of the spindle increases to about 20℃ after warming up operation.

Q. Is it possible to use my spindle on ATC (Auto Tool Changer)?

A. It could be mounted on ATC, but we do not recommend it due to forgetting disconnection of cords.

Q. How much is the rigidity of main shaft?

A. It could be 1μm of bending per 1kg pressure. Please refer to our the reference for details.

Q. How long does it take to get rotation speed I set?
Q. Is connection cord extendable?

A. It cannot be extended, but we have 3, 4, 6 and 8m connection cord.

Q. Is it possible to repair by myself?

A. We do not recommend to repair our products by yourself due to accuracy. Please do not disassemble.

Q. Do you sell parts?

A. We do not sell parts.

Q. Is it possible to use SFIDAs as hand tool?

A. Please do not handle them by hand, and it is dangerous.

Q. Do you sell spanner?

A. We sell spanners, and please place an order by product code on catalog.

Q. Do I need to switch input voltage?

A. You do not need to do so. Our products are compatible with AC100 to 240.

Q. What kind of safety protective function do your products have?

A. Excess and deficiency of air pressure
Overload of spindle
Disconnection of cable
Abnormality of controller and selector

Q. How much is the air pressure?

A. Please set as in range between 0.25 and 0.5MPa. In cases that power pack is far from regulator and/or you do not have a regulator, please adjust the air pressure on level meter of power pack.

Q. Is it possible to set power pack as horizontal position?

A. It is possible, and please put rubber feet on the marks at the corners of power pack.

Q. Is it possible to set power pack as horizontal position?

A. Brackets are available as options.

Q. Is it possible to control power pack externally?

A. It is possible, and signals are on the manual of power pack.

Q. Is it possible to operate multiple spindles at the same time?

A. It is not possible to operate multiple spindles at the same time although using selector pack.

Q. Do I need to change setting if I use SFIDA in overseas?

A. You do not need to change the setting, and they are compatible from AC 100 to 240 worldwide.
