Spindle Rebuild for All Manufacturers

Our capabilities allow you to utilize “good iron” that may only need some TLC.

Lucas has the expertise to accurately restore your spindle and sleeve to meet or exceed our own OEM specifications. Lucas Precision manufactures replaceable spindle taper sockets for any manufacturer’s large spindle bar. This restoration program salvages this expensive unit of your machine tool and simplifies future maintenance requirements. You can count on the professionals at Lucas Precision to restore the close tolerances to any large spindle bar and sleeve.


Exclusive Lucas 6-Point Restoration Program:

  • Regrinding spindle OD and taper
  • Replace sleeve bushings and bearings
  • Regrinding of sleeve bushings to fit OD of spindle
  • Chroming and regrinding all bearing diameters on OD of sleeve
  • Refit spindle in sleeve
  • Fit spindle key

 

Lucas Precision also offers in-place spindle taper grinding as part of our field service program. Our expert service technicians bring the equipment directly to your facility to help you reduce costs while saving time and labor.

We have modified spindles in various and unusual ways to accommodate rebuilt or remanufactured machines.

Manual Machine Upgrades

RELAY CONVERSION PACKAGES

The LM7 Electrical Relay Conversion Package was originally developed to allow the removal of obsolete Numerical Control systems on machines that are not good candidates for CNC retrofit. This package allows the machine to operate in the same manner as the ‘power shift’ manual machines of the same period of construction. In later years, we expanded the product line to allow for the replacement and elimination of worn out and malfunctioning relays on Lucas models that were already manual machines. The proprietary software can greatly extend your machine’s service life while reducing downtime.

Don’t risk down time or damage to your customers parts or - most importantly - the safety of your machinist when you can quickly and efficiently get your control up to date with modern pre-assembled electrical components.

 

  • Replaces 30-50 Obsolete or Worn Relays
  • Replaces All Makes of Electrical Relays
  • Diagnostic LEDs Speed Troubleshooting
  • Custom-Designed Software for your Specific Machine
  • In-stock for Immediate Shipment

 

The LM-7 conversion package is often installed simultaneously with a replacement Pendant.

 

An obsolete Numerical Control OR Manual relay panel from the early 1960’s looks like this:

 

After LM-7 conversion, any of the older panels will look more like this:

 

As you can see, most of the control system has been replaced with modern sold-state technology that is far less prone to wear and should, therefore, result in much less downtime.

In addition, each LM-7 is equipped with ‘Trouble-Shooting’ lights to assist with problem diagnosis and fused outputs to prevent damage to the LM-7 in the event of ‘shorts’ on the machine tool.


Replacement Pendants

LUCAS - NEW PENDANT CONTROL STATIONS

Due to the complete unavailability of the old style ‘turn/ tilt’ switches used extensively in Lucas 41B, 42B and other models and for which there are no commercial substitutes, Lucas Precision has engineered a complete replacement Operator Pendant with a 30-foot pre-attached cable that completely removes the need for these obsolete switches.

The pre-attached cable allows ease of installation and simple connection to your relay panel resulting in greatly lowered costs of maintenance as well as increased ‘uptime’ for your machine. If your machine requires more than a 30-foot cable, please let us know at time of order. New pendants are often installed simultaneously with a relay conversion package.

Lucas Replacement Operator Pendants are equipped with the same ‘pull-on’ ‘slap off’ operation of the earlier pendant designs so that - in hurried or panic situations - your operator will be able to rapidly stop the machine with the same ‘time-tested’ motions to which he has been accustomed. In addition, since we have created the new pendants to use modern, commercial switches as much as possible in our new design, replacement of individual switches is more rapid and less costly than the replacement of the old ‘turn-tilt’ switches.

We have available several different designs to replace the older types of pendants. To assist you in determining which Replacement pendant will function with your machine, we offer the following:

 

All three of these OBSOLETE Operator Pendants may be replaced by this new Design REPLACEMENT Operator Pendant.
