Manufactered according to EC directives and harmonized standards.

Initially, thes machines consist of a rigid Bow (24) that has two Flywheels: one is Driven Flywheel (33) and the other, Driver Flywheel (34). The Driver Flywheel (34) is engaged with a Gear Box (23) and this with electric Motor (22) three phase. The Driven Wheel (33) is mounted on the shaft of a dynamometric system called Tensioning System (39). A Band Saw Blade (41) is assembled on the two flywheels and properly tensioned by the Tensioning System (39), to keep it correctly tensioned on the Driven Flywheel (33) and the Drive Flywheel (34). The Bow (24) is assembled in the Vise Set (36) by Shaft (44), that enables this tilt in the blade plan, ie, in the cutting plan. The Band Saw Blade (41) and the Flywheels (33) (34) are protected at the Bow (24) rear portion by a Back Cover (25) (figure 01). The Vise Set (36) is basically composed: by a Cutting Table (35) and by Jaws Set (45), responsible to clamp rigidly the material to be cut (figure 02).

The Vise (36) has a longitudinal movement in the direction of clamping of the material, and another movement in the transverse direction of the blade, controlled manually. The clamping or the opening of the vise on the material is commanded manually or hydraulically, by Handlewheel (37) or by Buttons (18) and (19) on the Control Panel (20), respectively (figure 04). According to the machine’s construction, the Bow (24) rotates on a fixed point of the Cutting Table (35), to allow miter cutting (45° to the left, 0°, 45° and 60°to the right) on the material to be cut. A Cabinet (53) constructed of sheet steel, and extremely rigid, maintains all described set, in addition to having inside the Electrical Box (21), the Hydraulic System (47) and the Coolant (76) of cutting.The design of this cabinet makes the operator to work ergonomically correct (figure 05).

REV. 3 [1] - AGO/13

23


S4220 & S4230 - ING The Band Saw Blade (41) segment that performs the cutting is supported by 2 Guides: the Mobile (27) and the Fixed (30). These Guides are provided with Bearings (31) and Carbide Plates (32) that llow the blade to twist on the rotation plan of Flywheels (33) (34), to create the cutting plane. The Carbide Plates (32) have a function to align and not allow that the Band Saw Blade (41) rotates laterally on the movement axis. The Mobile Guide (27), close the Driven Flywheel (33), can be manually adjusted, to adjust the distance thereof with respect to material to be cut. These models have 2 configurations of Control Panel (20), which perform all movements of the Bow (24), by a simple press of the Buttons (16) and (17) (figures 04A and 04B).

8. CRITERIA FOR BAND SAW SELECTION 8.1. LIMITS AND RECOMMENDATIONS: Prior to beginning any kind of work with the machine, see that the job to be carried out is within the limits specified in table TECHNICAL DATA. If not, it is recommended to communicate in written to Starrett on the possibility of changing of some technical specification. The Starrett will reply in written regarding the best solution to be adopted.

WARNING! The StarreĆŠ is not responsible for damages caused to persons or objects, being forced the user's machine to check with a en on the characteris cs of the material to be cut in order to avoid any risk to the operator and / or third par es.

Being specified within the capabilities of the machine, the correct choose of band saw blade will be another important factor to improve the cutting performance.

8.2. CRITERIA FOR BAND SAW BLADE SELECTION: The proper selection of a saw band for a given application must consider some factors: Type of material, hardness, cutting section, capability of the machine itself, etc. There are 4 basics variables to choose a band saw blade: 1.

- Blade Type;

2.

teeth shapes

3.

Teeth (Pitch):

4.

Cutting Feeding and Blade Speeds.

REV. 3 [1] - AGO/13

45


S4220 & S4230 - ING 8.2.1. TEETH (PITCH): The pitch is number of teeth per inch (25,4 mm), that operator must be choose in function of material cutting section. The normal or annealed materials require at least 3 teeth inside cross section to be cut. It is ideal between 6-12 teeth. In general, materials with thin section require a band saw blade with a larger number of teeth per inch (25,4mm), or a band saw blade with “teeth thinner” being this opposite for materials with larger section.

8.2.2. CUTTING FEEDING AND BLADE SPEEDS. It´s important that the feed and cutting speed will be corrects. Starrett can to send a table “slide chart” type, to fast and easy selection of band saw blade, with specification of feeding and cutting speed for each kind of material. The same information are available in the Starrett Band Saw Catalog attached.

OBSERVATION: The best condi ons to cut are 3 to 12 teeth inside in the cross sec on to be cut, in the same me.

BLADE LENGTH The blade length varies according to the band saw machine type and specifications. Please find the correct blade length on your band saw machine user manual.

PITCH Pitch is the number of teeth per inch or 25mm. Cutting thinner sections requires a finer pitch (more teeth per inch/25mm). Thick sections require coarser pitches (fewer teeth per inch/25mm). The charts are good guidelines. Because the cross section limits in the chart are broad and overlap, choose a coarser pitch if the speed of cut is most important. Choose a finer pitch if finish is most important. Section Size (Inch)

Molybdenum Steels Intenss™ PRO-VTH recommended for cutting these materials GENERAL INFORMATION Consult our technical dept. for appropriate Advanz™ carbide style 1) When cutting materials of various hardness other than normal listing on speed chart, multiply speed or cutting rate given on chart by these factors to arrive at speeds and cutting rates for hardened material. CUTTING RATE FACTOR Rockwell Brinell SPEED FACTOR 0 0 225Bhn Up to 20Rc .75 .75 225-275Bhn 20-28Rc HARDNESS .54 .60 275-325Bhn 28-35Rc .40 .50 325-375Bhn 35-40Rc 2) Cutting normal or annealed materials requires at least 3 teeth to be in contact with the work, with the optimum being 6-12 teeth, and 24 teeth being too many. 3) When using Duratec™ PH or Duratec™ FB, reduce speed by 50% and cutting rate by 85%. 4) When cutting dry, reduce band speed 40-50%, and cutting rate 40-50%. Blade life will also be shorter by approximately 40-50%. 5) To choose correct Versatix™ MP for cutting tubing, pipe and structurals, first find the total square inches and divide by the distance the saw blade must travel to finish cut. This figure can be used as material width to determine Teeth Per Inch (Pitch). 6) To find estimated cutting rate for pipe, tubing and structurals, multiply factor for minimum wall thickness of section to be cut by the cutting rate shown for the same size solid material. 7) For foundry applications (aluminum, non-ferrous) use Advanz™ FS carbide tipped at 1000-5000FPM 8) For case hardened & hardened steels, use Advanz™ CS.

BLADE BREAK-IN Using the right break-in procedures for a bimetal blade assures longer blade life, faster cuts for a longer period of time and consistent performance. Conversely, blade life can be significantly compromised if the proper break-in procedures are not followed.

LONGER BLADE LIFE

NEW BLADE WITH RAZOR SHARP TEETH

TOOTH CORRECTLY BROKEN IN

The teeth on a new band saw blade are razor sharp. To withstand the cutting pressures of band sawing, the tip of each tooth should be honed to create an extremely small radius on its tip. Easy-to-cut material such as carbon steel and aluminum: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to about one-half the normal cutting rate for the first few cuts or for 50-100 square inches (323-645 sq.cm). C. Increase to the normal cutting rate. D. Avoid vibration. Hard-to-cut materials such as nickel-based alloys like inconel, hardened steels,tool steels and stainless steels: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to about threequarters of the normal cutting rate for the first few cuts or for 25-75 square inches (161-484 sq.cm). C. Then increase the cutting rate part way to normal for the next few cuts. D. Then increase to the normal cutting rate. E. Avoid vibration.

BAND SAW SERVICE & SUPPORT Starrett service technicians are available to tune up and perform preventative maintenance on your production sawing machine using Starrett Band Saw Blades, at no additional cost. They fully review machine condition, blade mounting and operation in detail, making adjustments, as required, to help maintain good sawing and long life for both the machine and blades.

TRAINING

TOOTH INCORRECTLY BROKEN IN

START TO CUT MATERIAL AT REDUCED CUTTING RATE

Starrett service technicians can also instruct saw operators on achieving the best performance of blade and machine for your applications. Contact your Starrett Band Saw distributor about arranging a visit to your workplace by a Starrett service technician.

AFTER BREAK-IN WHEN THE BLADE HAS FULLY ENTERED THE WORKPIECE, INCREASE THE FEED RATE OVER A SERIES OF CUTS UNTIL THE RECOMMENDED CUTTING RATE IS ACHIEVED


BAND SAW BLADE INSTALLATION GUIDELINES Always follow the machine manufacturer’s instructions and recommendations for blade changes and the safe operation for the band saw machine. The guidelines are not intended to replace the machine manufacturer’s instructions or recommendations. The general information contained in the guidelines is intended to assist in the proper installation of band saw blades. Proper blade installation achieves more efficient blade performance. Please contact your machine manufacturer for appropriate procedures for blade changes for your specific machine and your saw blade manufacturer for appropriate cutting recommendations. The L. S. Starrett Co. nor its employees, shall not be held responsible for the accuracy or completeness of these guidelines. Wear gloves when handling band saw blades.

Wear eye protection, safety shoes, and hearing protection.

FOLLOW INSTRUCTIONS CAREFULLY Follow all the safety instructions shown in the band saw machine operator’s manual and on the machine labels. Recognize and read safety and warning signs such as Danger, Warning and Caution. Follow the saw blade installation instructions for the make and model of the band saw machine.

BASIC BLADE CHANGE GUIDELINES Position saw head to appropriate location to facilitate ease of blade change. Follow required lock out tag out procedures. Position chip brush away from saw blade. Relieve saw blade tension and remove blade. Remove any chips from saw guides and band wheels. Select appropriate blade for cutting application. (Refer to saw blade selection chart) Unfold blade properly. Do Not Throw. Throwing the blade will result in tooth damage that will reduce saw blade performance. (Refer to unfolding procedure) Install blade with saw teeth pointing in proper direction.

Apply appropriate tension to the blade. Be aware of pinch points and keep hands and clothing clear of rotating blade.

Adjust guide arms to appropriate positions to workpiece. Adjust blade guides for proper blade support. Adjust chip brush to fully engage saw blade teeth to ensure proper chip removal. Check hydraulic fluid levels if applicable. Ensure appropriate cutting fluid placement and mix ratios as applicable per machine, cutting fluid, and blade manufacturer’s recommendations. Break in blade properly before reaching desired cutting rates.
