5.1.3 Lubrication
Lubrication is one of the single, most important maintenance issues and plays a key role in
assuring the performance and durability of the machine. The ProtoTRAK will automatically
lubricate the machine when it is turned on. At the beginning of the day, if the machine has been
left on overnight, it is recommended to go to service code 300 to lubricate the guides and
ballscrews.
Lack of lubrication using recommended type of lubricant can lead to a variety of problems with
your machine motion due to increased friction in the sliding ways. This increased friction may
lead to part inaccuracies and decreased life expectancies of your ball screws and linear guides.
5.1.4 Machining Set-Up
The machining set-up can greatly influence the performance of your mill. Be aware of the
following:
Problems With Can Contribute To:
Feed and Speeds (spindle rpm)
See below Poor finish
Machine chatter
Excessive speeds and feeds can break cutting
tools or wear tools prematurely.
Poor Tooling
Using the wrong cutter for an application
Entering the wrong size diameter.
Poor finish
Tool chatter
Parts incorrect size
Cutting too deep Part dimensions incorrect
Driving and cutting forces cause deflections,
since no material is totally rigid
Machine chatter
No coolant Poor finish, decrease the life of the cutter
5.1.4.1 Spindle Speeds
Spindle speeds are influenced by a number of variables:

Material
 Rigidity of the Machine Setup
 Coolant
 Cutter type, material and diameter
 Cutting Depth
As a general rule:
 Lower spindle speeds are used to machine hard or tough material or where heavy
cuts are taken.
 Higher spindle speeds are used to machine softer materials in order to achieve better
surface finishes. Higher speeds also apply when using small diameter cutters for
light cuts on frail work pieces and delicate setups.
Note: Cutter diameter greatly affects spindle speeds. The larger the diameter, the lower the spindle speed.
5.1.4.2 Feedrates
Factors that affect feedrates:
 Depth and width of cut

Design or type of cutter
