SAFETY

Additional Drill Press Safety

Serious injury or death can occur from getting clothing, jewelry, or long hair entangled in rotating spindle or bit/cutting tool. Contact with rotating bit/cutting tool can result in severe cuts or amputation of ﬁ ngers. Flying metal chips can cause blindness or eye injuries. Broken bits/cutting tools, unsecured workpieces, chuck keys, or other adjustment tools thrown from rotating spindle can strike nearby operator or bystanders with deadly force. To reduce the risk of these hazards, operator and bystanders MUST completely heed hazards and warnings below.

Eye/Face/Hand Protection. Flying chips

created by drilling can cause eye injuries or blindness. Always wear a face shield in addition to safety glasses. Always keep hands and fingers away from drill bit/cutting tool. Avoid awkward hand positions, where a sudden slip could cause hand to move into bit/cutting tool.

Avoiding Entanglement. DO NOT wear loose

clothing, gloves, or jewelry. Tie back long hair. Keep all guards in place and secure. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

Removing Adjustment Tools. Chuck key,

wrenches, and other tools left in spindle chuck or on machine can become deadly projectiles if thrown by rotating spindle. Remove all loose items or tools used on spindle immediately after use.

Workpiece Control. An unsecured workpiece

may unexpectedly shift, spin out of control, or be thrown if bit/cutting tool “grabs” during operation. Clamp workpiece to table or in table-mounted vise, or brace against column to prevent rotation. NEVER hold workpiece by hand during operation. NEVER start machine with bit/cutting tool touching workpiece; allow spindle to gain full speed before drilling.

Drilling Preparation.

or bit breakage, only drill into a flat surface that is approximately perpendicular to bit. Clear table of all objects before starting spindle. Never start spindle with bit pressed against workpiece.

Securing Table and Headstock. To avoid loss of

control leading to accidental contact with tool/ bit, tighten all table and headstock locks before operating drill press.

Correct Spindle Speed. Using wrong spindle speed

can cause bits/cutting tools to break and strike operator or bystanders. Follow recommended

tool and workpiece material.

Securing Bit/Cutting Tool. Firmly secure bit/

cutting tool in chuck so it cannot fly out of spindle during operation or startup.

Inspecting Bit/Cutting Tool. Damaged bits/cutting

tools may break apart during operation and hit operator or bystanders. Dull bits/cutting tools increase cutting resistance and are more

inspect bits/cutting tools

cracked bits/cutting tools immediately.

Like all machinery there is a potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions.

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

PREPARATION

Note: Be sure sling does not put pressure on

belt cover or belt cover can become damaged from force of sling while lifting.

Tighten all lock handles to keep moving

parts from shifting suddenly and unbalancing machine.

You must complete this procedure to maintain the warranty. Failure to do this could cause rapid wear-and-tear of spindle bearings once they are placed under load.

The spindle break-in procedure distributes lubrication throughout the bearings to reduce the risk of early bearing failure if there are any "dry" spots or areas where lubrication has settled in the bearings. You must complete this procedure before placing operational loads on the spindle for the first time when the machine is new or if it has been sitting idle for longer than 6 months.

Always start the spindle break-in at the lowest speed to minimize wear if there are dry spots. Allow the spindle to run long enough to warm up and distribute the bearing grease, then incrementally increase spindle speeds and repeat this process at each speed until reaching the maximum spindle speed. Following the breakin procedure in this progressive manner helps minimize any potential wear that could occur before lubrication is fully distributed.

OPERATION

Spindle Speed

Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.

To set the spindle speed for your operation, you will need to: 1) Determine the best spindle speed for the cutting task, and 2) configure drive belt on the appropriate speed range pulleys, and

3) adjust the spindle speed dial to produce the

required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the cutting tool, as noted in the formula shown in Figure 29.

*Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

Spindle

Speed (RPM)

Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. These sources will help you take into account the applicable variables in order to determine the best spindle speed for the operation.

Setting Spindle Speed

The Model SB1125 has two speed ranges that operate between 50–2000 RPM. The speed range is determined by how the drive belt is installed on the motor and center pulleys (see Figure 30).

Center PulleyCenter Pulley

Motor PulleyMotor Pulley

Drive BeltDrive Belt

*Double if using carbide cutting tool

Figure 29. Spindle speed formula.Figure 29. Spindle speed formula.

Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.

A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life. Refer to

Calculating Spindle Speed Drilling on Page 27 for a guide.

The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide

excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

Figure 30. Location of drive belt and speed pulleys.Figure 30. Location of drive belt and speed pulleys.

The high-speed range is obtained when the drive belt is positioned on the lower pulley sheaves, and the low-speed range is obtained when the drive belt is positioned on the upper pulley sheaves, as shown in Figure 31.

OPERATION

Calculating Spindle Speed for Drilling

The chart shown in Figure 35 is intended as a guide only. Always follow the manufacturer's speed recommendations if provided with your drill bits, cutters, or hole saws. Exceeding the recommended speeds may be dangerous to the operator or cause damage to the tooling.

The speeds shown here are intended to get you started. The optimum speed will always depend on various factors, including tool diameter, drilling pressure, material hardness, material quality, and desired finish.

Often, when drilling materials other than wood, some type of lubrication is necessary.

Lubrication Suggestions

Wood ............................................................... None

Plastics Brass Aluminum Mild Steel

Larger bits turning at slower speeds tend to grab the workpiece aggressively. This can result in the operator's hand being pulled into the bit or the workpiece being thrown with great force. Always clamp the workpiece to the table to prevent injuries.

MAINTENANCE

MAINTENANC E

Maintenance Schedule

Always disconnect machine from power before performing maintenance or serious personal injury may result.

For optimum performance from this machine, this maintenance schedule must be strictly followed.

For Machines Mfd. Since 11/21

Cleaning & Protecting

Cleaning the Model SB1125 is relatively easy. Vacuum excess metal or wood chips and wipe off remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Protect the unpainted cast-iron table and base by wiping it clean after every use—this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the table rust-free with regular applications of products like SLIPIT® or Boeshield® T-9 (see Figure 48 in Accessories).

Ongoing

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and ﬁx the problem before continuing operations:

• Loose mounting bolts.

• Worn switches/buttons/dial.

Worn or damaged wires.

•

• Damaged V-belt.

Any other unsafe condition.

•

Weekly

• Lubricate quill and column surfaces

(Page 33).

• Lubricate ball oilers (Page 34).

Monthly

• Check for V-belt tension, damage, or wear

(Page 35).

• Clean/vacuum dust buildup off motor.

• Lubricate quill and column racks (Page 34).

Lubrication

Since all bearings on the Model SB1125 are sealed and permanently lubricated, simply leave them until they need to be replaced. DO NOT lubricate them.

An essential part of lubrication if cleaning the parts before lubricating them. This step is critical because grime and chips build up on lubricated components, which makes them hard to move. Simply adding more lubricant will not result in smooth moving parts.

Clean components before lubricating them with recommended products like those in Figures 50–52 on Page 33.

⁄4".

The spring tension for automatic quill recoil has been pre-set at the factory. In most cases, it will never need to be re-adjusted during the life of the machine. However, if the quill stops automatically recoiling, the spring may need to be adjusted for additional tension. If it does need adjustment, the spring housing is located on the left side of the headstock.

If return spring should come loose from the spring cover and rapidly unwind, laceration or impact injuries could occur. Always wear heavy leather gloves and safety glasses when adjusting return spring tension.
