If you are in the process of purchasing a CNC Bending Machine, you will want to read this article, which will explain some of the most important considerations when making this investment. We will discuss Angle bending, Imprint bending, Back gauge adjustment, and stroke adjustments, as well as the features you should look for. This article will also help you understand how to use your CNC Bending Machine correctly. Then, you will be well on your way to maximizing the benefits of this machine.
CNC Bending Machine for Angle Bending
A CNC bending machine for angle forming allows the user to specify the exact length of a bend without the need for a reference. The machine features two bending bolds that rotate during the bending process, giving a signal to the computer that determines the final stroke required. This system compensates for the spring back of each bend and provides high angle accuracy of +/ 0.2o, instantly after the first workpiece is inserted. The machine reduces the material waste compared to manual adjustment.
The CNC bending machine for angle forming comes with many features. One of these is its ability to bend aluminum in different orientations. The machine comes with up to fifteen independent servo axes, allowing the operator to control the bending process in a three-dimensional manner. Another feature is the ability to fine-tune roll positions to minimize unbent flat sections. By using the BIT angle roller, operators can reconfigure the machine to bend smaller workpieces without wasting material.
CNC Bending Machine for Imprint Bending
A CNC Bending Machine for imprint bending is the ideal machine for a wide range of applications. The machine has all the benefits of CNC technology, including a modern touchscreen colour display and two axes of control. Programming is easy and intuitive, with the user interface enabling 200 different programs to be stored and swapped at any time. Stroke settings can be changed in steps of +/-0.1deg. The machine is easy to operate using a foot switch or a special manual control cable. It can be run in automatic or jogging modes.
The software allows the operator to program bends by dragging and dropping bend steps. It is error-proof thanks to the scanning of the part ID code. The graphical tool mapping displays provide information on tooling locations and types, allowing the operator to load the correct part program. The upper ram is equipped with LED mapping for accurate tooling positions. A CNC Bending Machine for imprint bending can also be fitted with spiral bending devices for heat exchanger production.
Back Gauge Adjustment in CNC Bending Machine
During a CNC bending job, a back gauge must be adjusted on a CNC bending machine to accurately gauge the material bending. The bend line is set at the nose of the punch, and a half of the material elongation goes to either side of the center. The backgauge location can be determined after performing the calculations. The backgauge position must be set from the front face of the die, a distance one-half of the width of the die body.
The back gauge adjustment is used to position the sheet in the length direction during the bending process. The adjustment value is obtained by pushing a button on the front button box. The table shows the conversion value of the adjustment value, and the machine also has a hand wheel for fine adjustments. A typical CNC bending machine comes with a hand wheel and an electric quick-adjustment lever for the backgauge.
Stroke Adjustment in CNC Bending Machine
In order to adjust the stroke, a CNC bending machine should have an oil pump. Start the machine and press the button to activate the pump. After starting the machine, adjust the stroke and make sure the plates are lined up with the bottom mold. You must remember that the upper die must have sufficient clearance, or you will end up damaging the mold. The machine’s stroke adjustment features manual fine tuning as well as electric quick adjustment.
When adjusting the stroke on a CNC bending machine, you should know the open height and closed height of the bending machine. The open height is the height of the upper and lower beams when the upper beam is fully opened. The closed height is the height of the upper and lower beams when closed. You must remember that some of the materials in the machine will come in contact with the variable die when changing the opening. For safety reasons, you should not stand behind the CNC bending machine while working.
CNC Bending Machine for Bending Prisms with Electronic Angle Measurement
The CNC Bending machine for prisms with angular measurement features electronic angular measurement and two flattened bending bars. It has high accuracy of +/ 0.1o, and it is a popular choice for small batches and single pieces. The bending tool rotates while the material is being bent, allowing the operator to set the required final stroke. The system also has an impact system, which allows the user to define the angle of rotation from which the stroke is calculated.
The manufacturing process of glass prisms begins with a block of glass called a “blank” that is ground by a metal diamond bonded wheel. During this step, the majority of the glass is removed quickly, leaving flat but coarse surfaces. Once the prism-to-be is close to the desired dimensions, the machine will perform a fine grinding process to remove scratches and subsurface breaks. The smoothened glass surface should appear cloudy.
