Types of Brakes
There are different types of brakes for varying applications. The differences manifest in the manner in which brakes are controlled and/or powered.
We sell a variety of different types of used brakes. Read below to familiarize yourself with the different types of used brakes for sale:
Hydraulic Press Brakes:
The main difference between a hydraulic brake and a mechanical brake is the manner in which the ram is driven. The ram on a hydraulic brake is powered by either one or two hydraulic cylinders.
The hydraulically powered ram makes hydraulic brakes one of the most desirable types of brakes in today’s marketplace. Manufacturing applications are often benefited by the flexibility that hydraulic brakes afford. Hydraulic brakes frequently have the desirable features of adjustable stroke, adjustable daylight, adjustable pressure and variable speeds. Unlike mechanical brakes, hydraulic press brakes deliver constant tonnage throughout the stroke. Hydraulic brakes have become popular in part because of their simplicity of design. This has allowed manufacturers to offer the machines at favorable prices when compared to their mechanical counterparts. Hydraulic Brakes are also comparatively quieter and have very few moving parts than mechanical press brakes.
Another reason that Hydraulic Brakes are so popular is that they can be equipped with CNC controls allowing all functions of the machine to be fully programmable.
CNC Press Brakes:
CNC stands for Computerized Numerical Control. If a brake is powered hydraulically, the valves can be tied into a CNC control so that the entire brake can be programmed for multiple bends with different depths. CNC Brakes typically have a back gauge that is controlled by the same CNC controller.
CNC gauging offers many benefits that can include improved precision and reduced set-up times which yield higher productivity. Total controllability of all machine functions yields a safer workplace with better profitability.
Mechanical Press Brakes:
Unlike hydraulic press brakes that are driven with a hydraulic pump and hydraulic cylinders, mechanical press brakes are actuated by an eccentric crank shaft. Where hydraulic brakes have a fully adjustable stroke length, mechanical brakes have a stroke length that is constant and is not adjustable. Generally, mechanical brakes are much faster than hydraulic brakes in considering strokes per minute. Mechanical brakes are known for their ability to maintain accuracy under full load.
Press Brakes (All)
In some cases, a fabricator may not know or care what type of brake they want for their application. In this category, we list all of our used press brakes. Here you will find used hydraulic brakes, used cnc brakes, and used mechanical brakes. For used manual brakes, such as Apron Brakes and Box & Pan Brakes, please continue reading.
While some brakes are powered either hydraulically or mechanically, some brakes are manually powered. These brakes are usually used to bend sheet metal and are sometimes known as folders or sheet metal bending machines. They are an economical tool for numerous forming and fabricating applications. Unlike powered brakes, manual brakes do not require the use of dies which can be costly. We cary several types of used manual sheet metal brakes; Apron Brakes and Box & Pan Brakes.
Apron Brake, Sheet Metal Hand Brake
Apron brakes are the simplest type of used manual brake. Apron Brakes feature a solid clamping bar for making straight bends. Almost every maintenance shop or small sheet metal fabricator makes use of manual apron brakes for light metal bending.
Box & Pan Brake, Sheet Metal Finger Brake
Box & pan brakes are also known also as finger brakes. They are ideal for straight bending as well as bends that form a box or pan shape. Frequently, box & pan brakes are used to bend heavier material than apron brakes. Like apron brakes, no assorted dies are needed for finger brakes.
