Shop Safety Rules

Your workshop is only as safe as you make it. Take responsibility for the safety of those who use or visit it. 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. Once the machine is mounted, consider your workbench to be permanent. If you must move the machine, first remove it from the bench

WARNING

1. Read this manual thoroughly before operating your machine. Don’t try to do more than you or your machine can handle. Understand the hazards of operating a machine tool. In particular, remember never to change speeds or setups until the machine is completely stopped and never operate it without first rolling up your sleeves.

2. Wear proper clothing. Avoid loose-fitting clothes, gloves, neckties, or jewelry that could get caught in moving parts. If you have long hair, tie it up or otherwise keep it from getting into the machine. Always wear non-slip footwear.

3.Protect yourself. Use ANSI approved safety glasses, goggles, or a face shield at all times. Use safety glasses designed for machinery operation; regular glasses will not do. Have extras available for visitors. Know when to wear a face mask or earplugs as well.

4.Keep your work area clean and organized. Cluttered work areas and benches invite accidents. Have a place for everything and put everything in its place.

5.Childproof your work area and keep children away from the 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.Keep track of tools. Remove adjusting keys and wrenches from the machine before operating. A chuck key or misplaced Allen wrench can be a safety hazard.

8.Avoid accidental starts. Turn the switch to the OFF position before plugging in the machine. Turn the speed dial to zero before starting your machine.

9.Ground your machine. The machine has a three-conductor cord and three-prong, grounding-type plug. Never connect the power supply without proper grounding

10.Keep your mind on your work. By paying attention to what you are doing and avoiding distractions you will spend many safe, enjoyable hours in your workshop.

11.Never leave your machine running unattended.

2: Safety

Machine Safety Rules

WARNING

1.Stop the machine before servicing. Stop the machine before making changes, removing debris, or measuring your work.

2.DonÕt over reach. Don’t reach over the machine when it’s operating. Keep your hands out of the way.

3.Turn the switch OFF. Turn the switch to off before plugging in the machine. Turn the speed dial to zero before starting your machine.

4.Use proper tooling. Use only recommended accessories and understand how they should be used before trying them out. Don’t try to make a tool into something it isn’t or attempt to use a tool in inappropriate ways. Remember to always use the proper tooling for the material you are cutting. Reference a general machining guide such as Machinist Ready Reference for recommended tooling for your material.

5.Secure your work. Before starting your machine, be certain that your workpiece 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. Going beyond the limits of travel will cause serious damage to your machine which will not be covered by your warranty.

7.Run your machine at recommended spindle speeds and feed rates. Always cut at the recommended speed and feed rates for the type of metal that you are cutting for optimum performance. Do not begin your cut until the machine has reached the full and proper speed.

8.Do not change the direction of the spindle rotation or leadscrew rotation while your machine is running. Changing the rotation direction of the spindle or leadscrew while your machine is running could cause serious damage to your machine.

9.Do not stop the spindle by hand. Always use your on/off switch to stop the spindle from rotating.

10.Do not clear chips by hand. Metal chips are very sharp and can easily cut your hand. Use a brush to clear chips.

11.Protect bed ways. When removing or installing tooling from your lathe spindle, place a piece of wood or other material across the bed to protect the ways from being damaged if the tooling is dropped.

12.Keep your machine maintained. Always replace worn or damaged parts before using your machine to prevent damage to your machine or the operator. Follow the maintenance schedule outline in this manual for peak performance.

Figure 4.8 Granite Carriage Assembly

The carriage assembly consists of:

•Crossslide table

•Carriage; the lower portion of the table that rides on the bed ways,

•Apron; the portion that hangs from the cross-slide table in front of the machine.

The carriage moves by hand or by power along the bed ways. Its function is to support the cutting tool rigidly while in the lathe mode and to secure the workpiece while in the mill mode. The carriage can be locked into place with the lock found on the back of the carriage.

The figure to the above right identifies and defines the major components of the carriage assembly.

A. Cross-SlideTable - The top portion of the carriage assembly. It supports the compound angle toolpost (not pictured) which holds the lathe cutters and tooling. The table also supports your workpiece when operating the mill. The cross-slide table has four, 7/16” sized t-slots for securing tooling and mounting workpieces.

4-8	For Assistance: Call Toll Free 1-800-476-4849

4: Machine Overview

B.Cross-Slide Handwheel - This handwheel moves the table toward and away from the operator along the Y-Axis. Rotating the handwheel clockwise moves the table away from the operator while moving it counterclockwise moves the table toward the operator.

C.Longitudinal Handwheel - This handwheel is located at the bottom left of the carriage assembly. Manually rotating the handwheel clockwise will move the carriage assembly along the X-Axis towards the tailstock end of the machine. Rotating the handwheel counter clockwise will move the the carriage assembly towards the headstock end of the machine.One revolution moves the assembly approximately .040”.

NOTE: This handwheel is for coarse movements only. Use the handwheel at the end of the leadscrew for fine movement (0.001”)

D. Half-Nut Engagement Lever - This lever closes the half-nut on to the leadscrew. When the half-nut is engaged, in the down position, the table assembly will be powered to move right and left along the X-Axis leadscrew.

! NOTICE !

The half-nut engagement lever is only engaged for rapid travel or threading operations.

E.Longitudinal and Lateral Powerfeed Selector - This selector determines whether the carriage will be powered to move along the X-Axis (longitudinal axis) or the Y-Axis (lateral axis). When the lever is in the upper position the table will move along the Y-Axis. When moved into the lower position, the table will move along the X-Axis. Center position is neutral.

F.Threading Dial - The threading dial is used to coordinate consecutive cuts when cutting threads. Restarting each cut from the same point on the dial ensures that each cut follows the same path, leading to accurately machined threads.

! NOTICE !

The threading dial can only be used when cutting inch (SAE) threads.

G.Saddle - The saddle supports the cross-slide table and moves along the X-Axis of the machine.

H.Apron - The apron houses the gear mechanism for the X and Y-Axis powerfeed.
