Industrial Metalsawing Bandsaw Blades Global Precision
Introduction April 1999 saw the beginning of a new era for the consistency. To achieve this, we operate within the Snap On production of Bahco bandsaw blades. A major investment QFS quality system or Quality Forward System, which uses programme was undertaken resulting in the opening, the ISO 9001:2000 framework.
Tooth forming High technology milling and grinding processes are used for precision tooth forming enabling sharper and stronger teeth to be produced. Setting Computer controlled measuring devices and camera monitoring systems check every tooth.
Service Storage and Distribution NDC - New Distribution Concept - is one of our single largest investments in customer service. It comprises two distribution centres in Europe and two in North America. Modern on-line computer processes ensure prompt and reliable deliveries and minimise stock handling for our customers. The NDC system provides continuously updated information to our production units. This allows them to produce the right products quickly and maintain high stock security.
The Research and Development Centre for Bandsaws is a Customer Support Service state-of-the art laboratory located in Lidkoping, Sweden. BandCalc™, our easy-to-use bandsaw cutting data program offers bandsaw machine operators quick access to The Centre, which develops and tests metal cutting saws, is staffed by qualified engineers and metallurgists and is equipped with machines and instruments for measuring all parameters that can influence the cutting operation.
Bandsaw Selection Guide Metal Cutting Non-Ferrous Cutting Maximum performance bandsaws specially designed for the greatest variety of metal cutting applications. Maximum performance bandsaws specially designed for non-ferrous cutting applications such as brass, bronze and aluminium. Also an excellent choice for cutting plastics, composites and abrasive materials.

General Information Band Length Types of Set The length of a bandsaw blade depends upon the sawing The set is the tilt, or angle, given to the teeth of the saw machine being used. Information for specific machines can blade to provide clearance for the blade body and the tooth be found in our software edges. Below are different types of set: program, BandCalc , TM see page 28, or from your sawing machine manufacturer.
General Information Bandsawing facts Machine Check frequently: • The operation of the chip brush. • The wear and alignment of the guides. • The band tension with a tensionmeter (see page 29). • The band speed with a tachometer (see page 29). • The coolant concentration with a refractometer (see page 29). Coolant / Cutting fluid The coolant lubricates, cools and carries the chips from the cut. It is important to: • Use good cutting fluid. • Use recommended concentration of cutting fluid.
General Information Feed Rate/Chips 1. Thin or pulverized chips - increase feed rate or lower band speed It is important that each tooth of the bandsaw blade cuts a chip 2. Loosely rolled chips -correct cutting data with the right thickness. This is determined by the selection of tooth pitch, band speed and feed rate. Start by selecting the 3.
General Information Tooth pitch for solid workpieces The diagram below will help you select the right pitch for cutting solids. The ideal choice is at the widest point of each field. Example 1: When cutting a Ø 6 inch (150 mm) bar, use 2 TPI, if an evenly pitched blade is your choice. Use a 2/3 TPI or a 1/2 TPI if you choose a variably pitched blade. Example 2: If you are sawing in soft materials like plastics, aluminium or wood, choose a pitch two steps coarser than recommended.
General Information Cutting pipes and profiles The diagram below will help you find the right tooth pitch for cutting pipes and profiles. The recommended tooth pitch for cutting profiles is found in the field where the width meets the wall thickness of the profile. Example 3: When cutting a 4" x .4" (100 x 10 mm) U-beam, select a 5/8 TPI or a 4/6 TPI blade. The recommended tooth pitch is found in the field where the outer diameter meets the wall thickness of the pipe to be cut. Example 4: When cutting a 1.
Tooth Shape Guide Tooth Shape guide Metal Cutting (Evenly pitched) The tooth shapes have different rake angles, clearance angles and gullet depths. This makes each tooth shape suitable for a specific application. Regular is a standard tooth shape with 0˚ rake angle. Regular is the traditional tooth shape for general cutting of small, solid workpieces. Positive PS has a 10˚-15˚ rake angle, a curved back and a gullet with large chip capacity.

Sawing Aids 3870 — BandCalc™ A Software program, based upon input from users with regards to material, machine, workpiece, economy and customer preferences, will recommend the best bandsaw blade for the application. It will also give necessary information on blade speed, feed rate and will calculate a cutting time and cost per cut for the application. BandCalcTM is a computer software programme that quickly and simply determines the best bandsaw blade for a specific application.
Sawing Aids Even the best blades need to run properly tensioned and at the right speed. That is why we offer a number of very important accessories that will help to get the best performance out of our quality blades. 3870 Tensionmeter Bahco’s tensionmeter is designed for easy, accurate measurement of the correct blade tension of all bandsaws. PRODUCT CODE 3870-TENSION METER ▼ Proper tension is necessary to provide straight cuts and long blade life, thereby reducing the cost per cut.
Troubleshooting Guide Machine Important Facts Band Breakage Crooked Sawing Guides and guide arms Check and adjust the guides regularly. Check if worn out and replace if necessary. Position guide arms as close to the workpiece as possible. Guides worn out Guide setting too wide Guides too far apart Guides worn out Guide arm loose Guides poorly adjusted Band wheels The wheels have to be kept in good condition and should be properly aligned.
