MACTECH LB PORTABLE BORING MACHINES

Mactech's portable boring bars are capable of precision line boring for a wide range of applications. The LB seriesfeature easy on-site set up and alignment, and an infinitely variable remote controlled hydraulic feed system,allowing the operator to achieve close tolerance results right at the actual work piece.

Model LB 100: Small diameter package for boring applications from 2" to 12" diameter, with extension capacityto 16".

Includes bearing support insert system, 48" bar and 96" barAxial feeds from. oo5" to rapid traverse2" Diameter axial feed columnSpindle speeds may vary from 165 to 5 r.p.m.15 inches of travel

Boring bars can vary in size and length to suit application

ModeILB200: Large diameter package for boring applications from 2" to 20" diameter.

Includes bearing support insert system, 48" bar and 96" barAxial feeds from. oo5" to rapid traverse3" Diameter axial feed columnSpindle speeds may vary from 125 to 5 r.p.m.18 inches of travel

Boring bars can vary in size and length to suit application

Hydraulic Power Supply: Includes remote control pendant, choice of 5 hp single phase electric motor (can be usedwith welding power supply) with 7 g.p.m. pressure compensated 20 gallon variable displacement pump, or 5 hp3 phase 220 volt electric motor coupled with 7 g.p.m. pressure compensated 20 gallon variable displacement pump,which combined with flow control provides from 2 -2oo r.p.m.

BORING BAR SET UP PROCEDURE

1. Select the proper boring bar to insure proper length of travel and diameter of finish bore required.

2. Locate boring bar in center of bores to be machined. This can be accomplished quickly by using the optionalself-centering alignment cones. The bar is supported temporarily in this manner while the bearing support bracketsare tack welded to bore faces.

3. The bearing support bracket mounting holes are approximately 1/8" oversized from the bolts used, this normallyprovides sufficient adjustment for final centering after bearing support bracket is tack welded in place. A dialindicator is often helpful.

NOTE: It is important to install the bearing supports brackets in such manner as to maintain the shortest possiblespan between the bearing support brackets. This will reduce tool chatter during machining.

4. The front bearing support bracket to which the spindle slide head mounts should be leveled to as close to a rightangle (90°) with the bar as possible. This will insure easy installation of the boring bar drive end (turned keyedend) into spindle slide head chuck. Note the length of the studs on the front bearing support, on which the spindleslide head assembly is to be mounted, are longer.

5. Position spindle slide assembly on front bearing support bracket mounting studs, secure using washers and hexnuts in proper location to insure alignment of boring bar and spindle chuck.

6. Insert boring bar drive end into the spindle chuck, (check key for proper location,) tighten chuck set screw onboring bar flat to secure. Make sure all hex nuts are tight on bearing support brackets before operating.

7. The knurled clutch knob located in the center of hand wheel allows the axial feed screw to be engaged (byturningclockwise)and disengaged(byturningcounterclockwise)fromthehydraulicfeedmotorfor easeof locatingand adjusting the spindle head using the hand wheel.

HYDRAULIC MOTOR OPERATION

1. The hydraulic rotation spindle and axial feed motors are both equipped with flow control metering valvesprimarily for controlling the speed of both functions.

NOTE: It is generally considered the best operating procedure to control hydraulic oil flow functions by"metering in" or restricting the oil flow to the motor. Control valvesprovide controlled flow in direction ofthe arrow marked on the valve body and free flow away from arrow.

2. Attach hydraulic hoses (non-interchangeable) from the hydraulic power supply unit to the motors.

3. Activate Hydraulic power supply -confirm electric source, verify proper rotation of electric motor and pumpas shown by arrows.

BORING BAR TOOLING

1. Boring bars for the Mactech LB 100 and LB 200 series machines come with 1/2" square broached holes withperpendicular tapped set screw holes to receive and secure 1/2" square tooling.Extended tool holders that mount through any of the square tool holes along the length of the bar are available inlengths up to eighteen inches. Tooling for facing and special operations is also available.

2. Dial indicator may be used to determine radial placement of tool bit.
