Smithy Warranty

Smithy 3-in-1 and Dedicated Machines are warranted for two years (unless otherwise
noted)to the original purchaser against defects in materials and workmanship. During that
time, Smithy will replace any defective parts that are returned to our warehouse, free of
charge. Upon receipt of the defective parts, Smithy technicians will arrange with you to
send replacement parts immediately. This warranty does not cover parts that are worn out
through the negligence on the part of the operator nor does it cover consequential
damages resulting from defects in material or workmanship.

SmithyCNC warrants its machines and control systems for a period of one (1) year to the
original purchaser from the date of purchase. If within one (1) year form the date of
purchase a SmithyCNC machine and/or control system fails due to defect in material or
workmanship, SmithyCNC will at their choice repair and/or replace components with new
or remanufactured parts free of charge.

(Some have asked why SmithyCNC machines have a shorter warranty period than Smithy
manual machines. There are several reasons, but the greatest factor is that, on average,
CNC automated machine tools, are operated a significantly greater number of hours
per day than the average manual machine. Also, by comparison, most of our competitors
selling benchtop CNC machines only offer a six (6) months warranty
machine have a full one (1) year warranty

Most warranty repairs and/or replacements are handled routinely, but sometimes request
for warranty service many not be appropriate. This warranty does not apply to defects due
directly or indirectly to misuse, abuse, negligence, accidents, repairs, or lack of routine
maintenance. This warranty is also void if the serial number of the machine or SmithyCNC
control system has been removed or has been altered or modified.

INSTALLATION & SET-UP

SET-UP CLEARANCES & CONDITIONS

When considering the permanent location for your SmithyCNC bed mill the following
should be taken into consideration:

•The machine should be installed on a flat surface so that the machine does not rock or
slide during operation.

•This location should be considered the machine’s permanent location for your machine.
If you need to move it, remove it from the stand first.

•Make sure your stand is level prior to placing the machine on the stand. Improper
installation and an unleveled machine can cause both numerical error and loss of precision
in your machining operation.

•The maximum temperature of your shop or working environment should not exceed
125 ºF.

•Humidity levels should not exceed 80%.

•Set up the bed mill stand so you have plenty of working space. Leave at least 3 to 4 feet
of clearance on the operating side of the machine. Note the suggested clearances of the
other sides of the machine in table 4.1.

Table 4-2. Power Requirements

STAND REQUIREMENTS

You will need a stand that is capable of supporting the weight of your machine plus the
maximum allowable workpiece depending on your bed mill. (Please refer to the
specifications chart for the bed mill that you ordered to obtain this specification.) You will
also need to add into this figure additional weight for work holding devices, cutters and
coolant. A good rule is to build a stand that can support 5 to 6 times the weight of the
machine without any appreciable, permanent deformation. The benchtop should be rigid,
level and well-supported. If you purchased one of the optional bed mill stands available
from Smithy, these stands have been designed to support the weight of the specified
machine.

Your work bench should be located in a vibration-free area with a floor that is designed to
support the full weight of the bench, machine, accessories, and materials.

Now that your machine is in place, it is important to properly secure it to your machine
stand. If you purchased a stand from SmithyCNC, the holes in the stand are pre-drilled and
tapped. If you make your own stand, please refer to the bolt pattern following this section.
These instructions assume that you have assembled your stand per the manufacturers
instructions. (The SmithyCNC-622 stand is pre-assembled.) If you purchased the optional
Smithy Stand (Item 80-060) then the holes for mounting your machine are pre-drilled and
tapped. If you are making your own stand use the bolt pattern below.

NOTE: The mounting holes in the base of the machine are 12 mm.

NOTE: Hole position in
castings can vary +/- 5 mm.
Before fabricating a stand
check these dimensions on
your machine.

NOTE: Bolt hole is M12

Figure 4.2 Bolt Hole Pattern

DANGER

SmithyCNC strongly discourages the use of casters or wheels on metalworking machine stands.
The weight of the machine could result in the stand tipping while being moved. Once the machine
is mounted, consider your work bench to be permanent. If you must move the machine, first
remove it from the bench.

MOVING FROM PALLET TO STAND

Once you have removed the crate per the instructions in the set-up guide. Y
remove the machine from the pallet onto the stand.

There are four bolts securing the machine to the base of the crate, use an adjustable
wrench to remove the nuts located on the machine base. Once the nuts have been
removed, tap the screws through the casting and pallet if they didn’t fall through when
removing the nuts.

ou will need to

If possible, use a forklift to remove the SmithyCNC-622 from the pallet which is the method
that we have elected to use and is the method illustrated below. If a forklift is not available,
we suggest using an engine hoist and chains to remove your bed mill from the pallet.

Step 1: Thread one strap under the machine towards the back and one strap under the
machine near the front of the machine.

13

mithyCNC 622 Operator’s Manual

S

Step 2: Use appropriately sized tow straps or rope when lifting your machine from the
pallet. (Lifting capacity should be three times the weight of the object you are lifting.)
Thread one strap under the machine towards the back and one strap under the machine
near the front of the machine.

Figure 4.3 Attach the tow ropes as illustrated above

NOTE: Before utilizing the lifting straps, examine them for tears or fraying that might
reduce the lifting capacity.

Step 3: Remove the coolant shield from the table. The shield is attached to the table with
a series of phillips head screws.

Step 4: Remove the cap screws securing the One-Shot lube system reservoir to the
machine, to avoid damage to it while removing your machine from the pallet.

Figure 4.4 Remove the lubrication pump in order to attach the lifting straps/chains

Step 5: Attach the tow straps or rope to the fork lift forks as illustration in figure 4.3. Y
should avoid straps riding on any sheet metal parts if possible as this could cause damage
to these parts. Take caution when lifting your machine into position that you straps are
fully supporting your machine.

LEVELING

Before any machining of the workpiece is done, it is crucial to level your machine for best
results.

Step 1: Find a relatively flat place for the installation of the machine and place the
machine stand in this spot taking note of the suggested clearances in table 4.1.

Figure 4.5 Level shown parallel to the Y-Axis

Step 2: Position the X & Y axes slides as close to the mid-stroke position as possible. (It
is shipped in this position.)

Step 3: Make sure your stand’s feet or leveling pads are touching the ground at the same
time. If not, adjust the feet to make sure the machine stand does not physically rock.

Figure 4.6 Adjusting stand leveling pads

Step 4: Once all the feet or leveling pads are touching the ground and the machine is not
rocking.

NOTE: Pictures shown in this document are assuming you have purchased the
optional machine stand with your CNC bed mill. If you have constructed your own stand,
adapt this process for your stand.

Step 5: Place a machinist level on the mill table, parallel to the Y-axis. If the level bubble
is not in the center of the scale, adjust the left and right side feet up or down to bring the
bubble in the center (i.e you are tilting the machine sideways about the Y axis of the
machine.)

Step 6: Now

, place the level parallel with the X-Axis. If it is not in the center of the scale,

adjust the feet at the front and rear of the machine to bring the bubble to the center. (i.e

ou are tilting the machine front to back about the X-axis of the machine.)

Step 7: Keep the levels in place, drive the middle feet to the ground and make sure the
bubble position does not change.

Step 8: Once both adjustments are completed, reposition the slides several times and
reposition the slides in the middle stokes. (

NOTE: This is done after you have hooked the

control system to your bed mill.)

Step 9: Check to confirm that the machine is still level by repeating steps 5 and 6. If the
machine appears to be unlevel, repeat steps 2-7.

NOTE: This leveling procedure should be rechecked every 6 months to ensure machine
leveling has not changed due to machine operation.

Lubrication System

This section covers the lubrication of your machine. There are two primary areas of
lubrication: areas lubricated by the single stroke lube system and the life greased bearings.

CAUTION

Remember, proper lubrication is very important. It greatly affects the performance and
longevity of your machine. If a the machine is operated without supplying the lubricating
oil, it will cause seizure of the sliding sufaces. Before opearting, visually inspect the oil on
the actual machine surfaces.

CAUTION

Use only recommended lubrication oils which are clean and free from foreign matter.
Periodically clean the tank and strainers/filters, if provided, inspect the equipment's
functioning or lube supply pipes for damaged to ensure optimum machine operation.

Headstock & Spindle Bearings

The bearings are of a precision class of accuracy. The spindle bearings are lubricated for
life with high grade grease, such as Kluber Isoflex NBU-15. This grease maintains its
lubrication properties at both low and high temperatures (- 70º F to 120º F). There is no
necessary lubrication to these bearings.

If the spindle starts making abnormal noises or gets very warm above (120º F), check for
damage of the spindle bearings after stopping the machine completely. The spindle should
be warmed up for approximately 15-20 minutes when the machine has been stopped for a
long period (for example 5 or more days).

PERIOD MAINTENANCE TASKS

CAUTION

Axis Bearing Adjustment/Axis Backlash

Backlash is the amount of movement the screw makes before the table engages. There are
a number of signs that may indicate that there is excessive backlash with your system:

• Rough/uneven surface finishes

• Dimension inaccuracies

• Table shakes under machining force

Even if none of these signs are present, it is recommended to check for backlash
compensation every 3-6 months depending on your usage of the machine. Please note,
SmithyCNC EZ-Trol software has provisions for compensating for backlash within the
program. This section of the manual is addressing mechanical backlash compensation.
There are three main mechanical reason for backlash:

1. Pre-loaded ball nut is damaged and is causing axial play between the nut and the screw
If the ball nut is damage, the only solution to this is to replace the ballscrew and ball nut
assembly.

2. The end support bearings are damaged. If you find that the end bearings are damaged,
follow the procedure below for replacing the bearings.

.

3. The ball nut mounting screws #70 on diagram 5, page 8-16 of this manual, are loose. In
this case move the table to the end of the stroke so that the nut mounting screws #70 and
#26 are accessible. Tighten the bolts and make sure the bolts or housing threads are not
damaged before tightening.

4. The end bearing tightening nut is loose. Follow step 6 and 7 in the following procedure
to tighten the bearings whenever required.

bearings are not creating any stop and go motion or are completely jammed. If you find a
jerky motion present, remove and reseat the bearing until there no jerky motion present.

Adjustment of Gibs

The axes slides have taper gibs. If the slide motion proves to be sloppy or uneven, you will
need to adjust the gibs until the motion “evens out”. The illustration in figure 6.1 shows an
exaggerated cut-a-way view of the taper gib system on the SmithyCNC-622. By retracting
the screw on the small end of the taper and tightening the adjustment screw on the large
end of the taper, you are decreasing the gap between the saddle and the main table; thus,
reducing the “fish tail” movement. Follow the procedure below for adjusting the gibs on
each axis of the machine.

Adjustment of X-Axis Gibs

Step 1: Make sure that the slide is properly lubricated before you start adjusting the
screws.

Step 2: Loosen the slotted screw on the narrow end of the X-Axis table. This is number 14
on diagram 3 on chapter 9 of this manual.

Step 3: Tighten screw number 22. This pushes the gib forward and reduces the the gap
between the table and saddle. Note: It may be helpful to remove the limit switch cover, part
number 2 by first removing parts.

Step 4: Tighten number screw 14 to secure the gib in place.

Adjustment of Y-Axis Gibs

Step 1: Make sure that the slide is properly lubricated before you start adjusting the
screws.

Step 2: Loosen the slotted screw #38.

Step 3: You will notice that the Y-Axis gib is notched in the front. Push the give forward,

into the second notch and retighten the screw. Once the gib as worn past this point, it will
need to be replaced.

Adjustment of Z-Axis Gibs

Step 1: To adjust the Z-Axis gib you will first need to remove part number 68, the junction
box cover in diagram 2 on page 9-6 of this manual. The part does not need to be
completely removed, only enough to expose the gib adjustment screw.

Step 2: Loosen part number 13.

Step 3: Tighten part number 8 which will push the tapered gib into the space between the

dovetail column and the mill head slide. This will reduce any fishtail movement in the
head.

TOOL HOLDING

OVERVIEW

The SmithyCNC-622 utilizes the a 10:1 ratio spindle with a build-in ER20 collet holder. Your
machine comes complete with a set of 15 collets, ranging in size between 3/16” and 1”.

Tool Holding Options

There are several tool holders that are used with milling machines.

Arbors come in different sizes and lengths with one end tapered to suit the inside spindle
taper or a straight shank arbor that works in conjunction with a collet. In the case of the
SmithyCNC-622 an you will need a straight shank arbor with a diameter that can be held
in the collet system. The term arbor is used for a general work holding device. Arbors can
mount drill chucks, slitting saws, gear cutters and shell end mills. An arbor is secured in
place with the drawbar system.

Collets (Spring Collets) are the most commonly used work holding device. They come
in a variety of styles and sizes. They are bored to hold a specific diameter. As the collet is
drawn into the spindle of the machine, the spring collet “closes” or “clamps” down on the
tool securing it in place.

End Mill Adapters are made specifically to hold end mills. Like arbors they come in
different sizes with one end tapered to fit the inside spindle taper or with a straight shank
to work in conjunction with a spring collet. End mill adapters are bored to a specific size
to hold endmills with a corresponding shank size. End mills are secured in the adapter by
friction and a set screw clamps down on the flat of the end mill for extra security

.

Installing the Tooling

Once you have determined the appropriate tooling for your operation, you will need to
secure it in the mill spindle an appropriate sized supplied ER20 Collets.

Step 1: Hold the collet holder with the supplied spanner wrench and place a M8 allen
wrench in the cap screw at the top of the millhead. Remove the collect chuck collar.

Step 2: Place the appropriate size R-8 collect in the spindle.
