Safet

The most important lesson to learn is that of safety. Caution and safety must be considered at

all times when using the Mini-Mill as well as any machine tool. Although the Mini-Mill posses

only limited possibilities of creating injury users should learn and follow all safety rules any

time they operate the Mini-Mill.

Safet Rules:

1. Never Run A CNC Machine Unattended - CNC machines are potentially dangerous.

Untrained people must not operate the CNC machine. CNC machines are not toys.

Keep kids away. Never let the machine run unattended. Always wear safety goggles.

Unexpected machine movement can occur at any time. You are responsible for the

safety of yourself and others. You are working at your own risk.

2. Always Wear Safety Glasses - foresight is better than no sight! The Operation of any

power tool can result in foreign objects being thrown into the eyes which can result in

severe eye damage. Always wear safety glasses or eye shields before commencing

power tool operation. For the best protection we recommend wide vision safety mask.

and standard safety glasses.

3. Know Your Mini-Mill Machine - Read the owner's manual carefully. Learn its application

and limitations as well as the specific potential hazards.

4. Ground All Power Connections - All the AC plugs are equipped with a three pronged

plug. Make certain the receptacle is properly grounded.

5. Keep Guards In Place - Never remove the safety shield. Use it for the protection of

flying debris.

6. Remove Adjusting Keys And Wrenches - Form a habit of checking to see that keys and

adjusting wrenches are removed from the spindle and machine prior to turning the

machine on.

7. Keep Work Area Clean - Cluttered areas and benches invite accidents.

8. Avoid Dangerous Environments - Do not use power tools in damp or wet areas. Keep

area well illuminated.

9. Keep Children Away - All visitors should be kept a safe distance from the machine

area.

10. Make Work Area Child Proof - with locks master cutoff switches.

11. Do Not Force Tool - Do not force tool or attachment to do a job it was not designed for.

12. Use The Right Tools - Do not force tool or attachment to do a job it was not designed

for.

13. Wear Proper Apparel - Avoid loose clothing or jewelry that could get caught in the

moving parts of the machine and spindle mechanism. Wear protective head gear to

keep long hair away from moving parts.

14. Use Safety Glasses - Also use a dust mask if cutting operation is dusty

MINITECH

15. Secure Work - Use clamps or a vise to hold work. Do not you your hands to hold work

down.

16. Do Not Touch Machine When It Is On - Avoid touching any part of the machine while it

is operating. If the proper settings are made and the work is fastened properly there is

no need to touch the machine.

17. Maintain Tools In Top Condition - Keep tools sharp and clean for best results and

safest performance. Follow instructions for lubricating and changing accessories.

18. Disconnect Tools - before servicing and when changing accessories such as end mills

and cutters.

19. Avoid Accidental Starting - Make sure spindle switch is off before plugging in power

cord.

20. Use Recommended Accessories - Consult the instruction guide. Use of improper

accessories may be hazardous.

21. Check That All Holding Locking And Driving Devices Are Tightened - At the same

time be careful not to over-tighten these adjustments. They should be just tight

enough to do the job. Over-tightening may damage threads or wrap parts thereby

reducing accuracy and effectiveness.

22. Be Aware Of These Safety Precautions - and use these as a basis for your safety

protection. Implement your own safety rules in conjunction with these.

Shipment Review

You should review your Minitech shipment to see how many packages you received. To do

this check first with the Ship List located on the outside of box number one. If there is only

one box then it will be marked as 1/1 or 1 of 1 box.

Review the ship list carefully. The ship list provides you with the contents of each box and the

items ordered. Although you may not be completely familiar with all the items it is important

that you become introduced to items as they become unpacked.

If you are uncertain of what some of the items are do not worry. Simply call Minitech on our

toll-fee telephone number if you need any assistance or would like further information on

setting-up your system. We are happy to assist you.

To open the shipment follow the instructions below.

1. Carefully open the crate containing your Mini-Mill machine. This should be a large wooden

crate.

2. As you open the box notice the four mounting screws that attach the mill to the plywood base.

This secures the machine during shipping and is not need for operating the machine.

Therefore remove the four mounting screws from the base prior to attempting to remove the

machine from the box. Note: Some Mini-Mills have only mounting straps that need to be

removed.

3. Once the machine is unsecured from the plywood base it can then be pulled-out of the box

and placed on a bench or desktop. Do not lift machine by the stepper motors. This should be

within a five-foot distance from the computer system you want to control your new Mini-Mill.

Remove any items from your bench that may interfere with the operations of the mill or items

that may become entangled with the spindle mechanism.

4. Open all other boxes (if any) and inspect their contents with the ship list provided.

Mounting the Machine

Use your discretion to mount the machine to a solid surface. We recommend mounting the

Mini-Mill to a table surface for maximum stability and machining accuracy. The four mounting

holes in the chip tray provide an excellent way to bolt the machine to a mounting surface. The

Mini-Mill can be mounted to a machined surface or pre-finished board using four machine

bolts and rubber washers and nuts available through local hardware stores.

This arrangement will give the Mini-Mill a stable and secure platform for operating the

machine. The rubber washers will help in reducing noise created by the spindle motor

spindle and cutting surface. The better the foundation the less vibration will occur and the

better the machine will perform.

Computer Interface Connection

The Mini-Mill is controlled by a PC based computer. This means that the signals used to

control the table movements and other operations are all controlled by the computer. The

Mini-Mill system is supplied with a USB cable with the same type of connector at each end. It

is a standard cable which can be purchased at any computer outlet if you should misplace

this item.

Do not attempt to connect the interface cable while either the computer or Mini-Mill is

powered on. This may cause electronic failure to These electronic components. For your

safety and the integrity of the equipment turn all devices off prior to making any interface

connection.

Setup the computer to be used with the machine and install the controller software. Refer to

the CNC Stepper Motor Control Box CS5SA8-1 manual for installation instructions. If at

anytime you experience inconsistent table motions or no table motions at all check this cable

to make sure it is properly installed.
