Topic: Factors Influencing the Precision of Bend Calculations on a China Press Brake Question: I am currently utilizing a China press brake that calculates the flat length of material before it undergoes bending. However, it appears that the machine does not adhere to any of the bend allowance formulas I have come across. For instance,…
Addressing Hardness and Other Material Property Variations Question: We have encountered cracking at the edges of several different 0.25-inch-thick A36 parts after bending (see Figure 1). We have previously bent these same parts without any problems, but recently cracks have started to appear. The external bend angles range from 75 to 90 degrees, and the…
Based on the different modes of upper blade movement, shearing machines can be divided into swing beam shearing machines and Hydraulic Guillotine Shear machine. The swing beam shearing machine is a hydraulic-powered shearing machine where the upper blade swings in an arc around a fixed axis during the shearing process, and the shearing angle is…
How does the shearing machine work? Working principle of the metal shearing machine: the upper blade is fixed on the tool holder, the lower blade is fixed on the lower bed surface, the bed surface is installed with a supporting ball, in order to facilitate the feeding and moving of the board, the rear baffle…
Press brakes are essential machines to have in your workshops. What sets these machines apart is their durability and versatility. They possess unique capabilities for forming and bending sheet metals, even handling small pieces effectively. One well-known machine in this category is the press brake. What are Press brakes? A press brake is a specialized…
The blades of the shearing machines are the knives used to cut sheet metal or other hard materials. These blades are usually made of high-hardness alloy steel or materials such as tungsten carbide to ensure their wear resistance and cutting ability. The items and requirements for inspecting the welding quality of the shearing machine’s blade…
Plate fiber laser cutting machine uses high-speed laser beam to cut the plate, it has the advantages of high efficiency, high precision and high power. 1. The working principle of fiber laser cutting machine Fiber laser cutting machine uses the thermal effect of the laser to heat the material to be processed, so that it…
Proper maintenance of your press brake tooling requires a few important considerations. Firstly, avoid storing it in a general storage rack away from the press brake when it’s not in use. This practice, commonly seen in the back of the shop, can significantly reduce productivity. It forces the press brake operator to leave the machine…
Fiber laser cutting machine emits laser beams from the laser device , laser passes through the optical path system, gathered into high temperature, pressure and density laser beam. The laser beam is irradiated on the surface of the object, which can make the object quickly reach the melting and boiling point. At the same time,…
A hydraulic press brake plays a vital role in industries involved in sheet metal fabrication. Within the sheet metal fabrication community, two popular types are commonly used: manual press brakes and hydraulic-powered press brakes. When compared to mechanical brakes, hydraulic press brakes offer enhanced safety and greater control. They typically feature multiple speed settings and…
When it comes to bending metal, two distinct processes vie for attention: press braking and roll-forming. To achieve the optimal balance of cost, time, and effectiveness for your metal fabrication project, it’s crucial to carefully consider the strengths and limitations of each method. Dive into the following key factors differentiating press braking from roll-forming. Firstly,…
Fiber laser cutting machine introduction Fiber laser cutting machine, also called laser cutting machine, metal laser cutting machine, as cutting and forming equipment in a variety of metal material processing plants, manufacturing processing plants. The equipment has high processing efficiency, low energy consumption, high quality of processing products (round incision, no deformation), the overall income…
