  • Page 7: Chapter 2: Safety

    Chapter 2 Safety Overview Smithy machines are proven to be safe and reliable; however, if abused or operated improperly, any machine can cause injury. Please read this manual carefully before you start machining. Proper use will create a safe working environment and prolong the life of your machine.

  • Page 8: Shop Safety Rules

    This list of rules is by no means complete, so remember that common sense is a must. DANGER Smithy strongly discourages the use of casters or wheels on metal-working machine benches. The weight of the machine could result in the bench tipping while being moved.
  • Page 9 machine while it is in use. Childproof your shop with padlocks, master switches, and starter keys or store the machine where children do not have access to it. 6. Never operate your machine under the influence of drugs and alcohol. 7.
  • Page 10 5. Secure your work. Before starting your machine, be certain that your work piece is properly and securely mounted. Flying metal is dangerous! 6. Do not run you machine beyond its limits of travel. Before starting your project, ensure that your work area does not go beyond the limits of travel on your machine.

  • Page 18: Chapter 6: Setting Up Your Machine

    Moving a machine tool can be dangerous. Improper techniques and methods may injure you and/or damage the machine. To find a professional to move and site your Smithy machine to look in your local Yellow Pages under “Machine Tools, Moving and/or Rigging.” If there is no such listing or your community does not have a rigging specialist, a local machine shop or machinist may be able to provide a referral.

  • Page 19: Lifting Your Machine & Placing It On A Stand

    Lifting Your Machine & Placing it On the Stand Once you have found a suitable location for your new lathe, you will need a mechanical lifting device, such as a engine hoist or fork lift, to remove the machine from the pallet and to place it on the stand. Remove the bolts, securing the machine to the pallet and any loose boxes or parts that may fall off the machine while moving it.

  • Page 20: Power Requirements

    It is recommended to connect to a 20 amp dedicated 110 VAC circuit. Check your local electrical codes for details on the supply circuit. The machine can be changed to 220 volt. Contact smithy for more information. Leveling the Machine Leveling of a machine tool is not making the machine level to the horizontal plane.
  • Page 21 Place a precision level across the bed of the machine close to the lathe chuck. Note the bubble position on the level. Move the level to the tailstock end of the machine. The bubble position should be the same as at the chuck end of the machine.
  • Page 22 Give special attention to the lead screw. Use a brush or cotton string to clean down into the threads. Once it's cleaned, your Smithy is ready for lubricating. Do this carefully and thoroughly before starting the machine. The lathe head has an oil site gauge.
  • Page 23 The apron has an oil reservoir. Oil is squirted one of the apron attach screw holes. It will run down into the apron. Oil should be half way up the site gauge on the front of the apron. The quick change gearbox is oiled by removing the plug shown below and squirting oil into the opening.
  • Page 24 There are oil buttons located in numerous locations on the carriage, table, tool post and tail stock. These should be oiled on a daily basis. A 30 weight non-detergent oil is recommended. When the machine is not in use, it is recommended that a thin coat of oil be applied to all exposed metal parts to protect the surfaces from corrosion.
  • Page 25 Adjusting the Gibs The objective of adjusting the gibs is to eliminate as much play in the X and Z axis as possible without having the tightness of the gib interfere with their movement and cause a decrease in the accuracy and performance of the machine due to excessive friction.
  • Page 26 X Axis Gib Adjustment There are also two adjustment screws. One in the front and the other one on the back of the cross slide which is shown in the images below. 1. To tighten the gib, loosen the rear screw about 2 turns. Slowly tighten the front screw while moving the cross feed fore and aft.
  • Page 27 Removal And Installation Of Lathe Chuck And Faceplate The spindle nose and chuck mounting is a D1-5 Type. This is one of the industry standard mounts and makes it possible to mount numerous styles and types of chucks to your machine. The chuck is attached to the spindle nose by 5 cam locks and studs.
  • Page 28 Chapter 8 Lathe Operations Overview The MI-1440L lathe is put through a initial run-in procedure at the factory before the machine is packaged for shipment. 1. Once you have your lathe setup, Smithy recommends that the spindle motor be run for about 5 minutes at each of the spindle speeds starting with the slowest speed.
  • Page 29 Spindle Operation 1. Once the desired speed is selected, move the Motor Engagement Lever downward to run in the forward direction for normal turning and threading operations. 2. Move the Motor Engagement Lever back to the center position to stop the lathe spindle.
  • Page 30 Chapter 9 Powerfeeding Overview There are several steps to set up for using the power feed. Determining the proper feed rate for a specific material and size of workpiece will require the use of reference guides such as Machinery's Handbook or Machinist Ready Reference .

  • Page 32 The Powerfeed engagement lever allows you to start the powerfeed for either the longitudinal direction or the cross feed direction. Moving this lever to the left and up will activate the power longitudinal feed. Moving the lever to the right and down will activate the power crossfeed.
  • Page 33 CHAPTER 10 Threading operation Overview This lathe is capable of cutting imperial or metric threads. There are gears on the end of the machine under the belt cover that will need to be changed for cutting some metric threads. Half Nut Lever This lever compresses and releases the half nut that engages the leadscrew.
  • Page 34 See the chart below shows the engagement numbers that can be used on inch threads. NOTE: The thread dial can be used on inch threads only, Metric threads require all mechanical connections remain intact throughout the entire threading procedure. Thread chart Inch The thread chart is used in the same manner as the feed rate charts.
  • Page 35 To set up for 24 threads per inch: 1. Place the 56 tooth gear in the “a” position and the 54 tooth gear in the “b” position. 2. Mesh both “b” and “a” to the 127 tooth gear. 3. Place the A-B selector in “A”, the C-D selector in “C”, the T-S-R-V selector in “V”...
  • Page 36 Setup and cutting metric threads 1.Open the pulley cover on the left end of the machine. 2.Loosen the bolt at the pivot point of the gear quadrant and the nut at the quadrant slot. 3.Loosen the nut at the center gear. 4.Remove the lower gear and install the required gear but turn it around so when it is installed, it will mesh with the...
  • Page 37 Do not disengage the halfnut until the thread is finished. All mechanical connections must stay intact for metric threads. If the thread is to be cut in multiple passes, 12.Turn the spindle off with the motor fwd/rev lever. 13.Back the cutter away from the workpiece. 14.Reverse the spindle motor and power back to the start of the tread.
  • Page 38 Installation 1. Place the chuck onto the end of the spindle and turn the cams clockwise. Rotate each cam enough to hold the chuck in place but do not tighten yet. When all 3 of the cams are engaged, go back and tighten each one.
  • Page 39 Follow Rest The follow rest is designed to support behind a small part to keep it from flexing away from the cutter during turning operations. The follow rest mounts on the left side of the carriage as shown below. The supports are adjusted before each pass since the material is getting smaller with each pass.
