Step 2 ‐ Lengthen the cutting time to 2‐3 times of what is normally required. Step 3 ‐ Start the break‐in operation. Step 4 ‐ After the break‐in operation is completed, set all parameters back to normal settings. TEST‐RUNNING THE MACHINE Test‐running this machine can ensure good machine performance in the future. We suggest you run the following tests on the machine before first use: Testing machine performance: Turn on the power and run a basic performance test after you finish installing the machine. Follow these steps to test machine performance: Step 1 – Disassemble shipping brackets and bolts. Step 2 – Install roller table (optional). Step 3 – Turn on the relay switch in the control box. Step 4 – Elevate the saw bow. (If your coolant pump is in reverse and the machine cannot run, please change the electrical phase.) Step 5 – After the saw bow ascends, extend the quick approach device. Step 6 – Remove the rust‐prevention grease with cleaning oil or kerosene. Step 7 – Start the coolant pump. Step 8 – Test these functions under manual mode: vise clamping/unclamping saw bow ascending/descending feeding forward/backward. ...
CUTTING OPERATION Step 1 – Check before you cut Power: Check the voltage and frequency of your power source. Coolant: Check if you have sufficient coolant in the tank. Hydraulic: Check if you have sufficient (at least two‐thirds or higher) hydraulic oil. Workbed: Check if there is any object on the feeding bed that may cause interference. Blade: Check the blade teeth and make sure there is no worn out teeth along the blade. Light: Check the work lamp or laser light (optional) and make sure there is sufficient lighting. Roller: Check all the rollers on the front and rear workbed can roll smoothly. Saw bow: Check the saw bow to see if it can be elevated and lowered smoothly Step 2 – Place your workpiece onto the workbed manually or by using a lifting tool e.g. a crane. Before loading, make sure the vises are opened to at least wider than the width of the workpiece. Step 3 – Position your workpiece. Step 4 – Clamp the workpiece. Step 5 – Turn the cutting pressure control knob to adjust cutting pressure according to the material. Step 6 – Adjust blade descend speed control knob to obtain a suitable blade descend speed for your material. Step 7 – Start running the blade. Before you start cutting, check again that there is no other object in the cutting area. Step 8 –While the blade descends, adjust the blade speed if necessary. You can do so by turning the blade speed control knob, clockwise to speed up and counterclockwise to slow down. The blade speed is displayed in the HMI touch screen. Step 9 – Select the proper cutting condition according to different material. Step 10 – After the entire cutting job is completed, elevate the saw bow to the top and open the vises to remove the workpiece. Step 11 – Clean the workbed by removing chips and cutting fluids. Step 12 – Lower the saw bow to a proper position then turn off the power. ...
STARTING AN AUTOMATIC OPERATION Step 1 – Use manual mode and cut the edge of the workpiece by using the same procedures as those described under manual operation. Step 2 – After the trim cut is completed and the saw blade has stopped at the lower limit position, press the saw blade up button to raise the saw bow until the quick approach bar is approximately 10mm (0.4inch) above the workpiece. Step 3 – Turn the Auto / manual switch to manual. Step 4 – Set your desired cutting length and quantity via the HMI touch screen. A total of 100 sets of cutting data can be programmed. Step 5 – Turn the Auto / manual switch to Auto. Step 6 – Press the saw blade start button and press the saw bow down button to start automatic cutting. STOP TERMINATING A CUTTING OPERATION To terminate a cutting operation, press either the saw bow up button or the emergency stop button. The saw blade will stop running when the saw bow up button is pressed. Both the saw blade and hydraulic pump motors will stop running when the emergency stop button is pressed. The machine will stop automatically when an error occurs. The error message will be shown on the screen. 4‐28 ...

INTRODUCTION TPI: The number of teeth per inch as measured from gullet to gullet. 2. Tooth Rake Angle: The angle of the tooth face measured with respect to a line perpendicular to the cutting direction of the saw. 3.Tooth Pitch: Tooth pitch refers to the number of teeth per inch (tpi). 1 inch equates to 25.4 mm. A distinction is made between constant tooth pitches with a uniform tooth distance, 2 tpi for example, and variable tooth pitches with different tooth distances within one toothing interval.
4. Tooth pitch The main factor here is the contact length of the blade in the workpiece. If it is 4P, 25.4 ÷ 4 P = 6.35 mm, that is, one tooth is 6.35 mm. If it is 3P, 25.4 ÷ 3 P = 8.46 mm If the number is small, it means that the tooth is large. What is written as 3/4 is that it is a variable pitch of large (3) / small (4).
The following diagrams suggest some costeffective ways of loading and fixturing. Be sure, regardless of the arrangement selected, that the work can be firmly secured to avoid damage to the machine or injury to the operator.
