.0 Features 7.6 Flood Coolant System 7.1 Miter Cutting Head The coolant pump must be submerged before operating to prevent damage to the pump. The miter cutting head is the unit that cuts the material and consists of a cast iron base, blade support unit and guard, transmission unit, and motor. The depth of cut is set by adjusting the depth cut stop. The miter cutting head swivels and locks into -45º, 90º, and +45º by means of a locking mechanism.
.0 Installation 10.0 Controls 8.1 Unpacking the machine 10.1 Control Panel Do not handle the packed machine using slings. The Control Panel (Figure 4) is located on the front of the cabinet stand and consists of the Power and High/Stop/Low switches, described below. To install the machine, first remove the packing, paying particular attention not to cut any electric wires or hydraulic hoses. Lift using straps (Figure 3). Power Switch – The Power switch has two positions, Off and On.
11.0 Operation 11.2 Miter Adjustment Before using the machine: To adjust the miter position follow the steps below while referring to Figure 10: Check that safety devices (e.g., blade guards) are in position and work perfectly and that personal safety requirements are complied with. 1. Move the miter position lock (A) to the right to release. 2. Adjust the head to the desired angle ranging from –45º to +45º by pushing on the back of the motor to the right or left.
12.5 Lubrication 12.0 Maintenance For long life and trouble-free operation, it is essential that this machine be kept well lubricated. The vise and leadscrew should be oiled daily. Pivot joints and bearings should be greased weekly. Check the gearbox oil level weekly; full level is top of sight glass with head in full up position. The gearbox oil should be changed annually. 12.1 Maintenance Requirements All maintenance must be carried out with the power switched off.
13.0 Blade Selection When using the J-FK350 cold saw, it is important to select the correct type of blade for the material to be cut. This section explains the limitations and specific applications of the different types of blades. 13.1 General Characteristics Fine Tooth Pitch – used for thin wall materials such as sheet steel, tubes and profiles Coarse Tooth Pitch – used for large cross-sections – for soft materials (aluminum alloys and soft alloys in general). 13.
13.5 Blade Structure For non-ferrous metals, it is common to use circular saws with brazed hard metal HM cutting edge, consisting of a disc made of alloy tool steel (71Cr1) on which the shape of the teeth and the seats for the cutting edges are made of Widia K10. These saws have shown excellent wear resistance but low resistance to impact, which is in any case a minor problem with non-ferrous materials.
Figure 17 Figure 19 Short swarf material such as brass, bronze, aluminum and hard cast iron require smaller cutting angles because the swarf becomes crushed immediately and the rake angle has little effect during the cutting stage.
.0 Troubleshooting the J-FK350 14.1 Blade and Cutting Problems Problem Teeth breaking Rapid tooth wear Broken blade Probable Cause Solution Incorrect lubricant/coolant fluid Ensure proper coolant flow. Material too hard Check the cutting speed, feed speed and air pressure parameters and the type of blade you are using. Disc not worn-in correctly With a new blade it is necessary to start cutting at half feeding speed.
14.2 Machine Fault & Operating Problems Problem Probable Cause Solution Electrical power supply Check: the phases; the cables; the plug; the socket. Also check that the motor connections are in place. Transformer Check that the voltages are present both on the input and output. Otherwise replace. Contactor Check that the phases in it are present both on the input and output, that it is not jammed, that it closes when powered and that it is not causing short circuits.
