Vacuum suction tool stand VSTS-WZ

We have developed under the patent license of Mitutoyo Co., Ltd. worldwide precision measuring equipment manufacturer.Utilizing Mitutoyo patent [No. 4616563]This is the next-generation tool stand to replace the conventional magnet stand (magnet base).It is used when measuring with a dial gauge or pick gauge (pick tester).Vacuum suction tool stand document



<Adsorption principle>

Adsorption principle explanation diagram of vacuum suction tool stand

The figure below shows the bottom of vacuum suction tool stand.)



 Vacuum suction tool stand is the device which can be used on the stone surface plate or ceramic surface plate when you need the precision measurement using dial gauge or pick gauge (pick tester).
Vacuum suction tool stand strongly adsorbs even on the stone surface plate and ceramic surface plate that can not use the conventional magnet stand (magnet base).

1. Although the magnet stand (magnet base) is limited to use with an iron platen, it can also be applied to stone and ceramic platens in the vacuum suction tool stand.
2. The tool stand which is usually used for measurement on stone platen is large and heavy, so workability of accuracy measurement is bad, but vacuum suction tool stand is small and lightweight. So workability is greatly improved.
3. Easy adsorption without vacuum pump: Compressed air from the factory compressor can be used.
4. Fixing / adsorption is easy to control : Easily adsorption / opening when holding the ejector.
5. If you already have your magnet stand (magnet base) on the vacuum suction tool stand, it can be used on stone surface platen, ceramic surface platen, etc.
6. Since the adsorption power is high, accurate measurement is possible with a dial gauge or a pick gauge (pick tester).

<F.A.Q. >

Q1. What is the size of screw holes to stand upright the support column
on the main body of vacuum suction tool stand?

A1. It is a coarse thread of M8 × P1.25. It is also possible to set different size of the thread screws by option (paid).

Q2. Why can you make vacuum with compressed air of air compressor?

A2. Small vacuum generator called ejector is attached to the back of the main body. Air is supplied from the ejector supply port and air is discharged from the exhaust port to create an air current. At the bottom of the main body there is a groove of an air reservoir, the air in it is discharged on the air flow created by the ejector and a vacuum is created.

Common precautions for vacuum system equipment

Please read before using the vacuum suction tool stand.


1.If the adsorbate (workpiece) falls and is considered dangerous, please provide safety measures to prevent falling.
2.Please do not use it when pressure of 0.1 Mpa or more is always applied to the vacuum circuit side. Since the vacuum equipment is not explosion-proof structure, there is a danger of causing damage to the main body.
3.Please pay attention to the drop of vacuum pressure due to trouble of supply air and power supply. Since there is a danger that the adsorbate will fall due to a decrease in adsorption power, please give a safety measure.
4.When two or more pads (vacuum suction tool stands) are piped to one ejector in a vacuum circuit, if one pad suffers adsorption failure (leakage), there is a danger that the other pads will be detached due to a decrease in vacuum pressure.
5.Please do not use such as to block the exhaust port of the ejector or increase the exhaust resistance. Vacuum does not occur, or vacuum pressure may decrease.
6.Do not use it in corrosive gases, flammable gases, explosive gases, chemicals, sea water, steam atmosphere or where they adhere. Also, please never inhale them.
7.Please attach a protective cover where sunlight is irradiated.
8.Regularly perform maintenance and inspection on the silencer element of the ejector and the filter element of the vacuum filter. Clogging of the element may cause performance degradation or trouble.
9.Please understand the vacuum ejector replacement element well for the element replacement operation.
10.Please check each port of the ejector according to the text of the manual and piping. There is a risk of causing damage to the main body if you mistake the piping.
11.For the ejector supply air, remove drains and dust and use clean air. Do not refuel with lubricator. Impurities contained in compressed air and oil may cause malfunctions and performance degradation.
12.Please do not give a strong tensile force or extreme bending to the lead wire. It may cause breaks.
13.If there is a lock nut in the product, please tighten it securely by hand tightening without using a tool for tightening. If tightening with a tool, it may cause damage to the lock nut or the main body. Also, if it can not be securely tightened, there is a possibility that the lock nut is loose and the initial setting is out of order
14.Do not swing or rotate the product whose resin body rotates forcibly. It may cause breakage or leakage of the main body.
