Related Product Introduction
CWR Processes Two Pieces Per Time
CWR, or Continuous Web Rolling, is a process used in metal forming where a continuous strip of metal is passed through a set of rolls to reduce its thickness and possibly alter its width. In the context of processing two pieces per time, this could refer to a dual-strip rolling setup where two strips are fed simultaneously into the rolls. This configuration allows for increased production efficiency compared to single-strip rolling.
Pre Forging Billet Wedge Rolling Mill
Pre forging billet wedge rolling mills are designed to prepare billets for subsequent forging processes. The main purpose of pre-forging is to remove casting defects, refine the grain structure, and achieve the desired shape and dimensions before the final forging operation. This process enhances the material's mechanical properties and ensures better surface quality and dimensional accuracy in the finished product.
Trailer Ball Mass Forging Press Machine
A trailer ball mass forging press machine is specifically designed to forge the ball portion of a trailer hitch, commonly known as a trailer ball. The forging process begins with a round billet of metal, typically steel, which is heated to a high temperature to increase its ductility. Once the billet reaches the appropriate temperature, it is placed into the forging press.
Cross Wedge Rolling Machine Replace Hammer
Cross wedge rolling is a process that uses a pair of wedges to progressively reduce the diameter of a billet as it moves through a set of rolls. Unlike conventional rolling, cross wedge rolling does not require a hammer; instead, it applies radial forces to the billet.
Eco Friendly Cross Wedge Rolling Machine
An eco-friendly cross wedge rolling machine (CWR) is designed to minimize environmental impact while efficiently performing the metalworking process of reducing the cross-sectional area of billets or slabs.
Cross wedge rolling (CWR) machines are highly efficient for producing automotive parts due to their ability to create complex geometries and strong, lightweight components. In the automotive industry, CWR is particularly useful for manufacturing parts that require high strength-to-weight ratios, such as connecting rods, crankshafts, drive shafts, and axles.
A high-efficiency cross wedge rolling (CWR) machine is an advanced piece of industrial equipment used in metal forging. It is designed to transform round or square billets into hexagonal, octagonal, or other polygonal shapes. The machine operates on the principle of applying a wedge that gradually reduces the billet's diameter from one end to the other, while simultaneously moving the billet forward through a set of dies.
A material saving CWR (cross wedge rolling) mill is engineered to minimize material waste during the metal forging process. This is achieved through precise control of the wedge angles, roll speeds, and the amount of reduction at each pass. The CWR mill can produce parts with very close tolerances, which means less machining is required after forging, further reducing material loss. Additionally, the CWR process allows for the use of smaller starting billets, as the progressive deformation effectively increases the length of the workpiece, which can be beneficial when dealing with expensive or scarce materials.
D46 Series Automatic Cross Wedge Rolling
D46 high-efficiency precision cross-wedge rolling is an advanced rolling technology that continuously and locally deforms the cylindrical billet through two rollers with wedge-shaped grooves so that the rolled workpiece is consistent with the shape of the groove at the bottom of the mold.
What is Cost Effective Cross Wedge Rolling Machine
A cost-effective cross wedge rolling (CWR) machine is an industrial forging device designed to produce metal parts with high strength and precision while minimizing material wastage and operational expenses. It achieves this by utilizing a wedge-shaped tool that progressively reduces the cross-sectional area of a billet as it is fed through the machine. The CWR process is well-suited for creating symmetrical parts with complex geometries, such as those found in automotive applications like axles, connecting rods, and drive shafts.
Features of Cost Effective Cross Wedge Rolling Machine
Good Product Quality
Because the metal fiber of the cross wedge rolling product remains continuous, the inner structure of the grain is refined and uniform, and the comprehensive mechanical properties can be improved by about 20%.
Save Raw Materials
Since the cross wedge rolling forming shaft parts are precision rolled, the machining allowance is small, and the machining allowance on one side is 1-1.5mm, and the non-matching surface can be realized without machining, so the utilization rate of materials is higher than that of traditional forging technology. In addition, cross wedge rolling can provide preforms for precision forging, and make full use of the waste heat of rolled products for isothermal normalizing heat treatment, saving a lot of electric energy.
Less Equipment Investment and Longer Mold Life
Cross-wedge rolling is local deformation, and the working load is small, so the equipment is light in weight, small in size and low in investment. Due to the small processing impact and the long service life of the mold, the service life of one time can reach more than 100,000 pieces, which is easy to realize automatic production and is suitable for mass production.
Working Conditions are Improved
The rolling process is a short-term continuous small deformation, no impact, low noise, which meets the environmental protection requirements of modern manufacturing.

Prepare
First, inspect the machine to make sure it is clean, well lubricated, and in good working order. Check all safety devices to make sure they are working properly. The billet is heated to a temperature suitable for rolling. This is usually within the forging range of the material.
Loading Billets
Secure the heated blank to the loading mechanism or feeding system, making sure it is properly aligned. Start the feeding system and slowly advance the billet to the rolling area.
Default Setting
Set up the wedge tool according to the part's specifications. This includes adjusting the wedge angle and positioning the rollers. Configure the control system to the required parameters such as rolling speed, force and stroke length.
Rolling Process
Start a rolling cycle. The upper and lower wedges will close around the blank, exerting pressure and causing the material to flow and reduce the cross-section. As the wedge advances, the blank gradually deforms. Adjust rolling force and wedge angle based on real-time feedback to maintain consistent deformation.
Sort By
Multiple passes may be required to achieve the final shape and size. Each pass further refines the part and increases its length. Between passes, the part can be rotated or flipped to ensure uniform deformation.
Complete Part
Once the desired shape and size is achieved, the rolling process stops. The finished parts are then removed from the machine and moved to a cooling area.
Cool Down
Allow the part to cool at a controlled rate to prevent defects such as cracks or residual stress. Depending on material and part requirements, air cooling or water quenching may be used.
