H-18/22 ASV 393115 November 2004, REV G Thank you, On behalf of everyone at HYD·MECH Group Limited, I would like to thank and congratulate you on your decision to pur- chase a HYD·MECH bandsaw. Your new machine is now ready to play a key role in increasing the efficiency of your operation, helping you to reduce cost while boosting quality and productivity.
MAINTAIN PROPER ADJUSTMENT OF BLADE TENSION, BLADE GUIDES, AND BEARINGS • HOLD WORKPIECE FIRMLY AGAINST TABLE. • DO NOT REMOVE JAMMED CUTOFF PIECES UNTIL BLADE HAS STOPPED. NO MODIFICATIONS TO THE MACHINE ARE PERMITTED WITHOUT PRIOR APPROVAL FROM HYD-MECH. ANY APPROVED MODIFICATIONS SHOULD ONLY BE UNDERTAKEN BY TRAINED PERSONNEL.
FOUNDATION, LEVELLING AND ANCHORING Machine location should be carefully selected. A flat con- crete floor area should be chosen. It should have enough free space surrounding the machine to enable free access for safe operation and maintenance. Machine should be leveled in both directions i.e. along and across its in-feed conveyor especially when machine is to be inserted into a larger conveyor system.
HYDRAULIC OIL AND CUTTING FLUID The H-18/22 SV bandsaw is supplied with Arco Duro 46 hydraulic oil. If it is necessary to change the oil to a different brand see the HYDRAULIC SECTION for equivalent grade oil. No cutting fluid is supplied with the machine. There are two types of coolant available: •...
SECTION 2, OPERATING INSTRUCTIONS This section has been prepared to give the operator the ability to set up the saw for most cutting situations. Before cutting any material, the operator should be familiar with all operations and controls as well as the basic cutting theory described below.

FRONT VISE - This switch has three positions, OPEN, HOLD and CLOSE. With the switch held in the OPEN position the vise will open all the way or until the switch is released. With the switch in the HOLD position, the vise will stay where it is and will not move freely although it will not resist a large force indefinitely without creeping.
Page 11
SHUTTLE VISE - This switch has three positions, OPEN, HOLD and CLOSE. With the switch held in the OPEN position the vise will open all the way or until the switch is released. With the switch in the HOLD position, the vise will stay where it is and will not move freely although it will not resist a large force indefinitely without creeping.
PLC 100 CONTROL SYSTEMS NOTE: This instruction manual is applicable to the H-18/22 SV equipped with a MITSUBISHI PLC manufactured after and including the following serial numbers: Machine Model Serial # H-18S B1001099, B1001103 DISPLAY WINDOW PLC FUNCTION KEYS CURSOR KEYS NUMERIC KEY PAD ENTER KEY OPERATION OVERVIEW...
ACTIVATING THE PLC Position the head, fixed vise, and shuttle vise switches to the NEUTRAL (center) positions. If any of these switches are not in the NEUTRAL position, the hydraulics will not start. The PLC control will become active when the HYDRAULIC START button is depressed and “held in”...
SINGLE PART CYCLE OPERATION In MAN mode, the PLC allows the operator to initiate a “Single Part Cycle” to cut one piece at a desired length. To accom- plish this, follow the procedure below. 1. A trim cut should be made before initiating the “Single Part Cycle” operation. 2.
AUTOMATIC OPERATION When the AUTO/MAN button is pressed, the red indicator light above it will come on, and the blade will stop if it has been running. The screen will change to the JOB display window as shown below and be ready for editing or starting a new job. All manual functions will be disabled.
WORKING WITH A QUEUE The purpose of a QUEUE is to allow the operator to run several jobs (max of 5) in series if they are of the same material and shape. In AUTO mode, press the key below the word “QUE” on the display and the display window will appear as shown. If you choose to VIEW the QUEUE, press the key below the words “VIEW QUE”...
HYDRAULIC FEED CONTROL The Hydraulic Feed Control is located to the left of the control panel. These controls allow independent control of Feed Force and Feed Rate. FEED FORCE KNOB USED TO SET FEED FORCE LIMIT (COUNTERCLOCKWISE ROTATION TO INCREASE AND CLOCKWISE ROTATION TO DECREASE).
CUTTING PARAMETERS CHART A full size CUTTING PARAMETERS CHART is mounted on the front of the saw. The chart contains five steps for the operator to follow in order to achieve optimum perfor- mance of the saw. These steps are detailed on the following pages. CHART EXAMPLE #1 We will use the parameters chart to set up the saw for cutting 8”...

many teeth per inch (T.P.I.) is recommended. For wide materials a blade with a coarse pitch should be used. The sketch can be referenced for the blade pitch changes for differing effective material widths. It is impractical to change the blade to the proper pitch every time a different width of material is cut and it is not necessary, but remember that the optimum blade will cut most efficiently.

When cutting materials that do not need constant coolant, such as Cast Iron, some coolant flow is required for blade lubri- cation to prevent blade scoring by the carbide pads as the blade moves through them. HEAD UP and DOWN LIMIT SETTING The head up limit is used to restrict the distance the head travels for each stroke.
BUNDLING OPERATION (OPTION) The bundling vises can be operated in direct conjunction with the front and shuttle vises or at a slower clamping speed. Either bundling can be turned on or off at any time. The on / off valves are shown in the photos. The speed at which the bundling jaws close can be adjusted as required by turning the flow control valves (shown in the photos) for each bundling cylinder.
SECTION 3, MAINTENANCE AND TROUBLE SHOOTING LOCK -OUT Purpose: To prevent injury to workers caused by unexpected start-up of machines being worked on. Where the starting of a machine or device may endanger the safety of a worker a. Control switches or other control mechanisms shall be locked out; b.
BLADE BRUSH ADJUSTMENT The blade brush is properly set when machine leaves the factory, but it wears out during operation and needs to be read- justed periodically. The blade brush assembly is found behind the drive side door and is shown below. To adjust the as- sembly, loosen the hex nut, turn the set screw counterclockwise until the wires on the brush touch the bottom of the blade gullets and tighten the hex nut.
CAM FOLLOWER ADJUSTMENT There are two cam followers mounted on the head frame. The set of cam followers are shown on the following page(s). One of them is fixed and the other is adjustable. The cam followers are factory set and usually do not require adjustment. In a properly adjusted system of cam followers only one side should be in contact with the guide.
IDLER WHEEL TENSIONER (ONE AT BOTH ENDS) CAM FOLLOWER GREASE NIPPLES 4 GUIDE ARM GREASE POINTS 2 VISE SHUTTLE VISE GREASE 2 SHUTTLE SHAFT BEARING HOUS- NIPPLES INGS GEARBOX LUBRICATION (H-18ASV WITH A503 GEARBOX) The Bonfiglioli A503 gearbox used on the H18 is supplied with 5.3 litres (1.35 US gallon) of Mobil SHC 630 synthetic oil.
Oil can be changed by draining through plug, E, and filling at plug F. If the type of oil is being changed, it is advisable to flush the old oil by filling the box with the normal quantity of the new oil, running it briefly at mod- erate speed, and then draining the box again, before re-filling it with a fresh quantity of the new oil.
7. BLADE TENSION – Blade tension pressure is factory set and should not require any farther attention. For adjustment see hydraulic schematic. 8. CARBIDE PRESSURE Carbide lock pressure is factory preset: • H-18SV 300 – 400 PSI • H-22SV 150 – 200 PSI The pressure gauge is not provided.

Auto Cycle Not Being Completed In auto mode, the PLC controls the saw functions through output relays. For a certain function to be actuated, the PLC must first see specific input(s). Like the output relays, the input relays are located on the PLC unit. Directly beside the input and output terminals are red LED’s (Light Emitting Diode), which will light up when the corresponding input is being received or output being actuated.
LED’s will light when the PLC commands specific outputs. IF an output LED is present then either the output relay is faulty/stuck or the output (3 amp) fuse is blown. IF a fuse is blown, a shorted directional valve coil, shorted noise suppressor at the coil or shorted wiring could be the cause (a good coil will measure between 30 to 40 ohms).
MITSUBISHI FX2N 48MR INPUTS AND OUTPUTS Input and output terminal identification: The top row of identification labels corresponds to the top row of terminals and the bottom row of labels to the bottom row of terminals. Input and output LED numbers correspond to the input or output of the same number. I.E.

CALIBRATION PROCEDURE Length calibration may be achieved in two ways, by inputting the ACTUAL LTH or LTH CONST parameter. To determine the ACTUAL LTH value, the LTH CLB (length calibration) procedure must be executed. In manual mode, position a piece of material, which is longer that the shuttle full stroke length and close the front vise.
To adjust “LTH CONST”, follow this procedure: Cut length ÷ Programmed length x Existing “LTH CONST” = New “LTH CONST” Example: Cut length of 11.998”, Programmed length of 12”, Existing “LTH CONST” parameter of 0.001256. 11.988 ÷ 12.000 x 0.001256 = 0.001255 The new “LTH CONST”...
SECTION 4, ELECTRICAL SYSTEM GENERAL INFORMATION This machine has been built to the customers requirements, however, if any voltage changes are required, consult Hyd·Mech service department before implementing any changes. INITIAL HOOKUP At initial hook-up it is important to check that the phase order is correct. This is indicated by the blade drive wheel revolv- ing in a counter clockwise direction and the hydraulic pressure gauge registering a pressure rise.
SECTION 5, HYDRAULIC SYSTEM The H-18/22 SV hydraulic system does not require any special work on a new machine before its start-up. The hydrau- lic tank is filled with Duro AW46 hydraulic oil and all machine functions have been tested at the factory to ensure proper operation upon initial start-up.
