Basic requirements for rolling bearings for machine tool spindles
| /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089'; |
With the development of science and technology, the spindle speed of machine tools is getting higher and higher, and the scale of shifting is getting larger and larger. Therefore, the demand for high-speed working stability of bearings is becoming higher and higher. The temperature rise of the machine tool spindle bearing is an important factor in restraining the bearing speed. Under normal circumstances, the correct selection of bearing type, worse grade, equipment method, clearance (preload) size, smoothing agent and smoothing method can improve the high-speed function of rolling bearings to a certain extent.
2. Life and carrying capacity.
For a typical machine tool, the life of the spindle is the period of application of the spindle accuracy. Therefore, the accuracy of the required bearing can satisfy the life expectancy of the spindle component. Regarding heavy-duty machine tools or powerful cutting machines, the primary bearing capacity of air-filter bearings should be the primary.
3. Stiffness and vibration resistance.
In order to ensure the processing quality of the machine tool, it is necessary to make the spindle system have a satisfactory stiffness, otherwise it will present a large repetitive error or even tremor. Anti-vibration is the ability to resist forced oscillations and self-oscillation. The vibration resistance of the main shaft is determined by the stiffness and damping of the main shaft and the bearing. The use of preloaded rolling bearings can effectively improve the rigidity of the spindle system.
4. noise.
In high speed grinding machines. The noise of the grinding head bearing is an important component of the whole noise, so low-noise rolling bearings should be used.

About Materials: We have 3 types of paper.
1. Art paper, this material is disposable material which is not waterproof and tearproof2. Synthetic paper, which is waterproof and tear-proof.
3. Tyvek paper, also called Dupont paper, this material is also tearproof and waterproof, and it is sofer and lighter than the Synthetic paper
About Size:
The size of the paper tape measure can be completely customized.
The maximum length that we can make is 160cm/62inch.
The standard width is 20mm. And wider size like 25mm, 30mm is also workable for us.
About Usage:
1. Art paper tape measure is widely used in medical area, such as wound measuring tape. It is disposable and it prevents cross-infection.
Measure in both inches or centimeters on one side, so you can record the units that are most appropriate for each patient visit.
2. Synthetic paper tape measure contains full color custom printing information on both sides.
It is used for multiple purposes such as measuring child height, circumference of furniture, room space calculating, etc. The synthetic paper is strong and resistant to water and tear, it can be used repeatedly.
3. Tyvek paper tape measure is Latex-Free, it prevents reactions in patients with a latex allergy when you use Tyvek paper measuring tapes.
They are made without latex to make it easier to accommodate people with allergies in your office, so you can provide the best level of patient care.
