Maintenance

Clean and deburr arbor shaft and ve ical face, clamp cups, cones and all other adaptors, daily

Clean tool Holders, daily

Wipe down adaptors and machined surf aces with anti-rust preventative, weekly

Lubricate main support Shaft grease fitting, annually (left side main housing)

Lubricate drum boring bar grease fitting, annually (inside feed assembly cover)

Problem Symptom Solution

Excess arbor runout

Chatter

Excess workpiece

runout

Poor surface finish

Dirt or rust on locking taper

Bent arbor

Arbor nut too tight

Dirty or warped workpiece

Dirty or dinged adaptors

Worn or chipped insert

Insert loose in tool holder

Tool holder loose in boring bar

Dirt and chips under insert

and tool holders

Too high of a feed rate

No stabilizer used

Too high of a spindle speed

Improper mounting techniques

Taper on arbor and inside spindle must be

cleaned before arbor is installed.

Replace arbor.

It is not recommended to use a wrench to

tighten Workpiece. Hand tighten only.

All rust, grease and dirt must be cleaned

from mounting surfaces of workpiece.

Adaptors must be kept clean. Reface or

replace any damaged adaptors.

Rotate or replace insert as needed.

Insert must be securely tightened into holder.

Tool holder must be securely locked into

boring bar.

Clean tool holder and boring bar each time

insert is rotated or insert holder is

repositioned. Replace insert if worn.

Coarse feed rates are used for roughing

passes and fine feed rates are used for

finish passes.

Install proper stabilizer for workpiece, see

stabilizers on other side.

Refer to Spindle Speed Selector Chart or

Operation Manual for recommended speeds.

Use the largest clamping cups possible and

use proper adaptors for composite pieces.
