Abrasive Machine
For abrasive machine, we are specialized in Flap Disc Making Machine, Abrasive Belt Making Machine, Flap Wheel Machine , Polishing Machine , Sanding Disc Machine etc.
The roll slitter machine type is designed to cut rolls of abrasive paper and cloth and to rewind them with grain both inside and outside.
Polishing Machine is for finish sanding of louver,shutter,raised panel,doors and frames. For sanding finishing of hard wood, softwood,MDF,veneer,plywood Inverts control spindle speed Converyor belt speedless The model can improve the curve surfave polishing rate.
The Flap Disc machine is a full automatic machine for flap disc production. From raw material feeding, loading on station, to finished flap disc unload on metal pin. Worker only need to put whole cluster of backing pad on metal pin, and put abrasive ribbon on abrasive belt shaft. High automatic, save labor hood.
The related abrasive products we can supply is Flap Disc Adhesive , bonded abrasives, Abrasive Sanding Disc, Surface Conditioning Product, if you have any needs about abrasive tools, please kindly feel free to contact us.

1. Axial positioning of the part on the shaft: the axial positioning of the part on the shaft; the first depends on the size of the axial force it receives. In addition, the ease of the shaft and the ease of assembly and disassembly of the parts on the shaft should be considered. The influence on the strength of the shaft and the reliability of the operation. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Commonly used axial positioning methods are: shoulder (or collar), sleeve, round nut, retaining ring, conical shaft head number.
.1) Shaft shoulder: The shoulder is composed of the positioning surface and the excessive rounding. To ensure that the end face of the part can be close to the positioning surface; the radius of the shoulder fillet must be smaller than the fillet radius or chamfer height of the part hub hole, to ensure The strength is satisfied to accept the axial force; the shoulder height is h=(2-3)R.
.2) Collar: The function and scale parameters of the collar are the same as those of the shoulder; the width b≥1. 4h. If the collar blank is cast; the material is less and lighter. If it is made of round steel Cheng; then dregs materials and processing hours.
.3) Bushing: The bushing is positioned by means of the part that has been determined by the azimuth; its two end faces are the positioning faces; therefore, there should be a high degree of parallelism and straightness. In order to position the parts on the shaft firmly; The length of the shaft section should be shorter than the length of the part hub by 2~3mm. The use of the sleeve can simplify the layout of the shaft and reduce the stress gathering. However, because the sleeve and the shaft cooperate loosely; the two are difficult to be concentric; therefore, it should not be used on the high speed shaft. Avoid imbalances.
(4) Round nut: When the interval between the two parts on the shaft is large; and the thread is allowed to be cut on the shaft; the end face of the round nut can be pressed to position the end face of the part to locate. The round nut is convenient for assembly and disassembly; Fine thread to enhance the anti-loosening ability and reduce the strength of the shaft to weaken and stress gathering.
(5) Shaft end baffle: When the part is seated at the shaft end; the shaft end baffle and the shoulder, the shaft end baffle and the conical surface can be used to fix the part in both directions. The baffle is fastened to the shaft end by screws and is pressed and positioned. The end face of the part. The method is simple and reliable, easy to assemble and disassemble; but the threaded hole needs to be machined at the shaft end.
(6) Conical surface: It can be used in cooperation with the shaft end baffle and round nut. The taper of the conical surface is small; the required axial force. The gray bump is rough. Generally, the taper is 1:30~1:8.
(7) Elastic retaining ring: cut the annular groove on the shaft; insert the elastic retaining ring into the groove; use its side surface to press the end face of the positioned part. This positioning method is good in craftsmanship and convenient to assemble and disassemble; The strength of the shaft is weakened; it is often used for shafts with small axial forces and high stiffness.
(8) Tapered pin, locking ring, set screw: These three positioning methods are often used for the optical axis.
2. The circumferential positioning of the part on the shaft: the positioning method is always selected according to the size and nature of the transmitted torque, the unevenness of the centering accuracy of the part, and the difficulty of processing. The commonly used circumferential positioning methods are: key, spline, forming , elastic ring, pin, interference and other joints; commonly known as hub joint.
