The Crozier Model 30AUTO Automotive Speed Lathe is the industry standard for the production polishing of rotors and armatures. The air-collet closure and electric brake speed up the polishing operation. The 1 horsepower fixed speed motor is set for the optimum polishing speed for both the copper slip rings and commutator. The bearing surfaces are easily polished with emery cloth. The air-collet closure grips the parts tight and when finished, release the part with minimal effort. A large double row front bearing is on the collet end. Standard 5C collets are used. This has been the standard polisher in the automotive aftermarket since 1982. Don't be fooled by the imitators. Insist on the original.
The Crozier Model 30AUTO Speed Lathe is attached to a wooden pallet. The Speed Lathe is attached to the bottom of the container with four carriage bolts. Remove the bolts from the mounting holes. The Speed Lathe is ready for installation. Check the box for all parts. If any damage is noted call the freight company immediately. The freight company is responsible for the safe delivery of the machine and if immediate notification of damage is not reported, you might not be able to file a claim for damages.
The Crozier Model 30AUTO Speed Lathe must be secured to a suitable stand at all times.
The Crozier Model 30AUTO Speed Lathe is designed to operate with sealed bearings. No provision has been made for introducing grease into the bearings. Should it become necessary to change bearings only sealed bearings of electric motor quality C/3 fit with seals or shields on both sides should be used. No bearing spacers are required.
The Crozier Model 30AUTO Speed Lathe input requirement is 240 Volts, three-phase power. Motor rotation is counter-clockwise, looking directly at the shaft. A qualified electrician is required to install the electrical connection. The machine must have a power disconnect placed near the machine. The electrician must run the wire through conduit from the disconnect to the control box. The incoming power is hooked up to the #1, #2, and #3 terminals. Ground is terminal #4. Make sure all connections are tight before energizing the motor.
The Crozier Model 30AUTO Speed Lathe requires 90 PSI dry air for proper operation. The air operates the collet closure. Never operate the Speed Lathe without the air connection hooked up. Under no circumstance should the machine be run with a part in the collet and the air off.
Wait for the Speed Lathe to come to a complete stop before attempting to open the collet closure. DO NOT open the collet closure with the Speed Lathe running. Make sure the part is secured in the collet and the collet is closed under air pressure before turning the machine on. DO NOT place long parts that can whip or extremely heavy parts that are not in balance or straight.
The foot pedal activates the air closure, in the text, the valve is referred to as a foot valve. The foot pedal is normally hooked up when the machine is received. if not, it is important to make the right connection. The collet is drawn into the spindle with the foot pedal untouched. When you push down on the foot pedal, the collet is pushed off the taper and the collet opens. If the operation is backwards reverse the two (2) air lines going into the back of the machine. To load the collet, find the collet key in the spindle nose. Check the collet threads and drive slot on the collet. Make sure the collet threads and drive slot are clean. Insert the collet in the spindle nose lining up the key. Press the collet firmly against the draw tube. Turn the draw tube hand wheel clockwise drawing th collet into the nose. When the collet is nearly in the spindle place the part in the collet. Continue turning the hand wheel until the part is tight in the collet. When the part is tight in the collet push down on the pedal at the same time turn the hand wheel two (2) detents clockwise. Release the pedal. The part should now be tight. If the part is not tight, push down again and repeat the procedure turning one (1) detent each time.
If the collet sticks or is hard to open, polish the collet surface that slides into the precision hole. Only high quality collets should be used. For best results, we recommend, Hardinge®: 5C collets. Hardinge® Collets are available from factory outlets in major cities or from reputable tool houses. If the machine is used in an abrasive environment the spindle hole should be cleaned when you change collets.
The threads on the draw tube can wear from extended use or using worn or undersized collets. If this occurs the collet will not lock into the spindle and the work piece will not be held. The draw tube must be replaced if this happens. Always check the collet threads for damage or foreign material. In an abrasive environment clean the collet threads at regular intervals. If the collet keeps working itself loose check the rotation. If the rotation is correct make sure the drive key has not sheared off. If this happens replacement of the key is necessary.
There should be a minimum of .075 inches in the opening and closing movement of the collet. The standard 5C collet can accept a work piece variance of .005 inches. Any larger variance will cause the collet to distort and not hold the part properly. Do not under any circumstance force the collet to hold a undersized part. Serious damage can result from such actions.
The Speed Lathe is equipped with a mechanical brake that is attached to the back of the drive motor. The brake is released on motor start up and is applied when the motor is stopped. If the spindle needs to be turned by hand, there is a brake release lever on the back of the brake.
As with all equipment proper care should be taken. Safety glasses must be worn at all times while operating the Speed Lathe. It is the responsibility of the end user to determine the suitability of the Speed Lathe in their application.
This machine is a precision machine tool. The components used in its manufacture are of the highest quality and the machined parts are held to very exact tolerances. If you expect the machine tool to last, you must take proper care of it.
The Crozier Model 30AUTO Speed Lathe can be cycled on and off as fast as you can do the work.
