How is Horizontal Bandsaw Machine different from a Vertical Bandsaw Machine?

Bandsaw Machine

BH4220AA band saw machine is a power tool with a blade that has teeth on one edge to cut various materials. It is designed to cut curves, circles and irregular shapes on pieces of wood or metal although it can also cut straight lines. The band in the machine rides on two wheels that rotate on the same plane.

There are basically 2 important types of band saws depending on their use,
Timber cutting band saws are used in timber mills to rip lumber. This type of band saw need to be serviced regularly by saw filers.

Metal cutting band saws are built for friction cutting of metal and they have brush wheels that prevent chips from being stuck between teeth. A metal cutting blade also has a metal cooling system to wash away chips and keep the blade lubricated and cool. This article is going to focus on band saws for cutting metal.

Types of Band Saw Machines Available for Metal Work

1. Horizontal band saw machines are used in holding the work piece stationary while the blades swing down via the cut. These are used to make cuts in large pieces such as bar stock or pipe to length. It is normally used in big manufacturing companies and metal fabrication stores because it’s able to cut materials from plastics, soft metal, titanium, graphite and even exotic metal. It is conveniently small in size and is able to hold the work piece in place so the blade can cut through. Vibration free and smooth functioning with lesser noise and reduced wastage are features of a modern horizontal bandsaw machine used in industrial applications.

2. Vertical band saw  is also known as the contour saw because the blade is kept stationery and the work piece is moved periodically across it. This type of a band saw is usually found at home and local shops. They are small in size and require less power. It is used to cut pliable metal using its circular endless blade for complicated cuts. Vertical band saws have an inbuilt blade welder for repairing broken blades or allow the blade to be purposely cut in order to do interior cutting. It also has a blower for blade cooling and to blow away the chips from the work area.

Differences between Horizontal Band Saw Machine and Vertical Band Saw Machine

Horizontal band saw is used to cut large pieces of metal while vertical band saw can only cut small pieces.

BH4228Horizontal band saw can cut the hardest metals but a vertical band saw can only cut pliable soft metals.

The horizontal saws use a lot of power to cut hard metals while vertical saws only use less power.

A vertical band saw is used to cut curves and complicated shapes while the horizontal saw cannot cut curves because it applies gravity only.

In horizontal band saw machines, it is the blade that moves to cut the material but in vertical band saw machines the work piece is the one that is moved across the stationery band.

Vertical band saws are used in homes and small shops while horizontal band saws are used in big industries. Read more in detail for Bandsaw Machine.

Conclusion:

There are new advancements being made in metal cutting band saw machines such as more developed tooth geometries and pitches, computerizing the machines new treatments like cryogenic treatment to increase production rates and give the blades a longer life.

Different Types of Press Brakes Available Today for Metal Work

There are various different types of press brakes described by the means of force application. These are; pneumatic press brake, servo-electric press brake, hydraulic press brake as well as mechanical press brake. The operation Hydraulic presses brake is simply by hydraulic cylinders that are synchronized on the C-frames which moves the upper beam. In mechanical press brake, there is an addition of energy to a flywheel with a motor that is electric. The flywheel is engaged by a clutch in powering a crank mechanism which vertically moves the ram. Speed and accuracy are the two advantage of the mechanical press brake. The pneumatic press brakes uses the pressure of the air in developing tonnage on the arm while as the servo-electric brakes uses a servo-motor in driving a belt drive so as to exert tonnage on the arm.

How Press Brakes Work?

Press brakes work by simply stamping cold steel into a mold referred to as a die. The machine is fed with the sheet and aligned over a mold that is special. The press brake press or lowers a boom so as to force the metal into the mold. By doing this, a cold formed metal object is formed. Any number of electronic machines is used by this brake for the alignment of the metal sheet. There are some that incorporate the use of CNC type arms which help in positioning the metal over a die. Mostly, a computer is used to time hydraulics and compress through a motor that is uses electricity. Read more in detail for Every Press Brake Operator to Ensure Safety during the Work.

Advantages of Hydraulic Shearing Machine over the Regular Mechanical Models

A shearing machine is an industrial equipment with rotary disks and blades used to cut hard iron sheets and metal bars. The term shearing means to apply a high pressure tool on a metal bar once to remove a part of the metal. All metal shears use the same technique in cutting where there is a fixed upper blade, a lower blade and an adjustable clearance separating the two. When a force is applied on the upper blade it forces the lower blade to cut and separate the metal into two.

HYDRAULIC SWING BEAM SHEARING MACHINE

Shearing machines are categorized depending on the shape of its blade, linear or circular.

Linear shearing machines are used to cut metal with a thickness of over 2mm and they are operated with hydraulic power or hand operated machines for thinner metals.

Circular shearing machines are used to cut circular blanks and rings from metal and are operated by an electric motor. The best types of metal for shearing are bronze, aluminium, brass and mild steel. Metal shearing is cost effective and easy and hence preferred in industries and even homes.

Types of Shearing Machines

1. Bench shear- The word bench is because the machine is mounted on a bench to increase its mechanical ability. It is used to cut rough shapes of medium sizes of metal. However, small bench shearing machines are fitted with ground cutting blades and are light weights making it easy to have clean and fast cuts.

2. Guillotine- This means that the machine is hand or foot powered and sometimes mechanically powered. The material to be cut is first cramped with a ram and a moving blade goes down and shears the metal. a power shearing machine consists of a shear table to put the material being sheared, a a holding device to hold the material in place to avoid movement, a gauging device to make sure the material is in the right place and the lower and upper blades to do the cutting.

3. Power shears - This type of a shearing machine is electrically powered to shear large pieces of metal regardless of size. Alternatively they can be powered with hydraulics to cut metals that are too bulky for transportation.

4. Throat – Less shear- This means that the metal being cut can be moved around the cutting blade freely so it’s flexible. It’s used for complex cuts and curves.

Advantages of using Hydraulic Shearing Machines over Mechanical Models

  • Hydraulic shearing machines are fast and accurate and make it easy to cut a lot of metal in factories.
  • Hydraulic shears don’t require a lot of maintenance as mechanical models and hence are cost effective.
  • Hydraulic shears are usually compact machines and hence take up less space even though they apply the same kind of pressure as mechanical shearing machines.
  • Hydraulic shearing machines secure metal with cramps while cutting hence ensuring smooth cuts and even 90 degrees cut. There are a wide variety of hydraulic shearing machines in the market to cater for all sizes of metal.

How to use Hydraulic Shearing Machines Safely?

  • Always have specialist operators to work on the machine
  • Maintain cleanliness in the machine and follow the operating rules to avoid hazards.
  • Always make sure to switch off power of the machine after use.

Conclusion:

Hydraulic shearing machines are more effective and easier to use than mechanical machines but should be handled with care by qualified personnel only.
