China Angle Grinder Cutting Disc Pressure Plate Suppliers - Factory Direct Sales for Multiple Applications
Characteristics
The manufacturer's cold heading forming processing technology mainly has these characteristics:
Extremely efficient
After cutting round steel into sections, it can be formed by one or several impacts through the mold, without the need for gradual cutting like turning technology.
Material saving
It belongs to the category of low cutting processing, with a high material utilization rate, usually reaching over 95%. However, traditional turning processes can cut off a large amount of iron filings, resulting in waste.
Better strength
Metal undergoes plastic deformation during the forming process, and the internal grain structure is refined and distributed along the contour, forming continuous fiber flow lines. Therefore, the strength and fatigue resistance of the parts are usually better than those of products processed by cutting.
Good size consistency
The size is guaranteed by the mold, suitable for large-scale production.
The processing process is roughly as follows
1
Material preparation (disc or round steel)
2
Cutting
3
Cold extrusion forming (one-time forming on hydraulic press or cold heading machine)
4
Punching (if required by design)
5
Tapping
6
Heat treatment (to improve hardness)
7
Surface treatment (rust prevention)
Two main advantages
Compared with ordinary turning pressure plates, the pressure plates manufactured by cold heading technology have two main advantages:
Cost advantage
When producing in large quantities, the unit price is much lower than that of CNC lathe machining.
Structural strength advantage
Due to the metal streamline not being cut, it performs more reliably when subjected to impact forces caused by wheel locking or accidental impact.
The pressure plate of the angle grinder is used in conjunction with the 100, 125, 150, 180, and 230 models of angle grinders. It adopts carbon steel cold heading technology for one-time forming, which further improves the working strength of the material compared to traditional cutting or powder metallurgy processes. It combines rigidity and flexibility, and has sufficient strength for use without damaging the spindle thread or twisting the cutting abrasive.
The supporting conversion extension rod adopts carbon steel cold heading process for one-time forming, which enables ordinary carbon steel materials to reach the strength standard for use without heat treatment. This product can be used in working conditions where ordinary angle grinders cannot work, such as deep cavity cutting and polishing, and can also switch the angle grinder to electric drill mode, achieving multi-purpose and flexible use of one machine.
The surface of the product is treated with coating, and the processes of galvanizing, blackening, chrome plating, nickel plating, titanium plating, etc. can be customized by customers at their discretion.
This product is directly sold by the manufacturer, allowing customers to buy the most affordable products. Wholesale prices are lower for large quantities. Customers are welcome to inquire.
Frequently Asked Questions (FAQ)
What are the main characteristics of cold heading forming processing technology?
