FOUNDATION DRAWING

GENERAL DESCRIPTION

Lathe Bed (Fig. 3)

The lathe bed is made of high-grade iron. Combining high cheeks with strong cross ribs produces a bed of low vibration and rigidity. It integrates the headstock and drive unit to attach the carriage and leadscrew. The two precision-ground V-sideways, reinforced by heat hardening and grinding, are the accurate guides for the carriage and tailstock. The main motor is mounted to the rear of the left side of the bed.

Headstock (Fig. 4)

The headstock is made of high-grade, low-vibration cast iron and is bolted to the bed with four screws. It houses the main spindle with two precision taper roller bearings and the drive unit.

The main spindle transmits the torque during the turning process. It also holds the workpieces and clamping devices (e.g., a 3-jaw chuck).

Carriage (Fig. 5)

The carriage is made from high-quality cast iron. The slide parts are smoothly ground and fit the V on the bed without play. The lower sliding parts can be easily and simply adjusted. The cross slide is mounted on the carriage and moves on a dovetailed slide. The gibs allow adjustment of the play in the cross slide.

Move the cross slide with its conveniently positioned handwheel. There is a graduated collar on the handwheel.

A four-way tool post is fitted on the top slide and allows four tools to be clamped. Loosen the center clamp handle to rotate any of the four tools into position.

Apron (Fig. 6)

The apron is mounted on the bed. It houses the half nut with an engaging lever for activating the automatic feed. The half nut gib can be adjusted from the outside.

A rack mounted on the bed and a pinion operated by a handwheel on the carriage allow the apron to travel quickly.

Leadscrew

The leadscrew (A, Fig.7) is mounted on the front of the machine bed. It is connected to the gearbox at the left for automatic feed and is supported by bearings on both ends.

The hex nut (B, Fig.7) on the right end is designed to take up play on the leadscrew.

Tailstock (Fig. 8)

The tailstock slides on a V-way and can be clamped anywhere. It has a heavy-duty spindle with a Morse taper No. 2 socket and a graduated scale.

A clamping lever allows the spindle to be clamped at any location. A handwheel moves the spindle at the end of the tailstock.

NOTE:

Fit the securing screw (C, Fig. 8) at the end of the lathe to prevent the tailstock from falling off the lathe bed.

VEVOR METAL LATHE OPERATION

Replacement of Chuck

The head spindle holding fixture is cylindrical. Loosen three set screws and nuts (A, Fig.13, only two are shown) on the lathe chuck flange to remove the chuck. Position the new chuck and fix it using the same set of screws and nuts.

Tool Set-Up

Clamp the turning tool into the tool holder.

The tool must be clamped firmly. When turning, the tool tends to bend under the cutting force generated during the chip formation. For best results, the tool overhang should be kept to a minimum of 3/8″ or less.

The cutting angle is correct when the cutting edge is in line with the center axis of the workpiece. The proper height of the tool can be achieved by comparing the tool point with the point of the center mounted in the tailstock. Use steel spacer shims under the tool to get the required height if necessary. (Fig. 14)

Change Speed

• Unscrew the two fastening screws. (B, Fig.15) and remove the protective cover.

• Adjust the V-belt (C, Fig.16)to the corresponding position.

• Tighten the tension pulley and fasten the nut again.

Manual Turning

Apron travel, cross travel, and top slide handwheel can be operated for longitudinal or cross feeding. (Fig.17)

Longitudinal Turning with Auto-Feed

Select the feed speed or thread pitch using the table (A, Fig.18) on the lathe. Adjust the change gear if the required feed or thread pitch cannot be obtained with the installed gear set.

Change Gears Replacement

• Disconnect the machine from the power source.
• Unscrew the two fastening screws and remove the protective cover.
• Loosen the locking screw (B, Fig.19) on the quadrant.

• Swing the quadrant (C, Fig.19) to the right.

• Unscrew the nut (D, Fig.20) from the leadscrew or the nuts (E, Fig.19) from the quadrant bolts in order to remove the change gears from the front.
• Install the gear couples according to the thread and feed table (Fig.20) and screw the gearwheels onto the quadrant again.
• Swing the quadrant to the left until the gearwheels have engaged again.
• Readjust gear backlash by inserting a standard sheet of paper as an adjusting or distance aid between the gearwheels.
• Immobilize the quadrant with the locking screw.
• Install the protective cover of the headstock and reconnect the machine to the power supply.

Straight Turning (Fig. 21)

In the straight turning operation, the tool feeds parallel to the workpiece’s axis of rotation. The feed can be manually turned on the handwheel on the lathe saddle or the top slide or activated automatically. The crossfeed for the depth of cut is achieved using the cross slide.

Facing and Recesses (Fig. 22)

In the facing operation, the tool feeds perpendicular to the workpiece’s axis of rotation. The feed is made manually with the cross slide handwheel. The crossfeed for cut depth is made with the top slide or lathe saddle.

Turning Between Centers (Fig. 23)

To turn between centers, the chuck must be removed from the spindle. Fit the M.T.3 center into the spindle nose and the M.T. 2 center into the tailstock. Mount the workpiece fitted with the driver dog between the centers. The driver is driven by a catch or face plate.

Note: Always use a small amount of grease on the tailstock center to prevent the center tip from overheating.

Taper Turning Using Tailstock Off-Set

Offsetting the tailstock can turn work to a side angle of 5. The angle depends on the length of the workpiece.

To offset the tailstock, loosen the locking screw (A, Fig. 24). Unscrew the set screw (B, Fig.24) on the right end of the tailstock. Loosen the front adjusting screw( C, Fig.24) and take up the same amount by tightening the rear adjusting screw (D, Fig 24) until the desired taper has been reached.

The desired cross-adjustment can be read off the scale. (E, Fig.24). First, retighten the set screw (B, Fig.24) and then the two (front and rear) adjusting screw to lock the tailstock in position. Retighten the locking screw (A, Fig.24) of the tailstock. The workpiece must be held between two centers and driven by a face plate and driver dog.

After taper turning, the tailstock should be returned to its original position according to the zero position on the scale of the tailstock. (E, Fig.24)

Thread Cutting

Set the machine to the desired thread pitch (according to the threading chart, Fig.20). Start the machine and engage the half nut. The tool will cut the initial threading pass when it reaches the part.

When the tool reaches the end of the cut, stop the machine by turning the motor off and backing the tool out of the part so that it clears the thread. Do not disengage the half-nut lever.

Reverse the motor direction to allow the cutting tool to traverse back to the starting point. Repeat these steps until you have obtained the desired results.

NOTES

Example: Male Thread

• The workpiece diameter must have been turned to the diameter of the desired thread.
• The workpiece requires a chamfer at the beginning of the thread and an undercut at the thread runout.
• The speed must be as low as possible.
• The change gears must have been installed according to the required pitch.
• The thread cutting tool must be exactly the same shape as the thread, absolutely rectangular, and clamped to coincide with the turning center.
• The thread is produced in various cutting steps, so the cutting tool must be completely removed from the thread (with the cross slide) at the end of each cutting step.
• The tool is withdrawn with the leadscrew nut engaged by inverting the change-over switch.
• Stop the machine and feed the thread cutting tool in low cut depths using the cross slide.
• Before each passage, place the top slide approximately 0.2 to 0.3mm alternately to cut the thread free to the left and right. This way, the thread cutting tools cut only on one thread flank with each passage. Keep cutting the thread free until you have almost reached the full depth of the thread.

VEVOR Metal Lathe Accessories

Three-Jaw Universal Lathe Chuck

This universal chuck may clamp round, triangular, square, hexagonal, octagonal, and twelve-sided stock. (Fig.26)

Note: New lathes have very tight-fitting jaws. This is necessary to ensure accurate clamping and long service life. With repeated opening and closing, the jaws adjust automatically, and their operation becomes progressively smoother.

Note:

The factory mounted the original 3-jaw chuck on the lathe in the best way to guarantee holding accuracy: with two “0” marks (A, Fig.26) on the chuck and chuck flange.

There are two types of jaws: Internal and external jaws. Please note that the number of jaws fits the number inside the chuck’s groove. Do not mix them. When you mount them, please mount them in ascending order: 1-2-3. When you take them out, take them out in descending order: 3-2-1, one by one. After finishing this procedure, rotate the jaws to the smallest diameter and check that the three jaws fit well.

Four-Jaw Independent Lathe Chuck

This special chuck has four independently adjustable chuck jaws. These permit the holding of asymmetrical pieces and enable the accurate set-up of cylindrical pieces. (Fig.27)

Drill Chuck (Optional)

Use the drill chuck to hold centering drills and twist drills in the tailstock. (B, Fig.28)

Morse Taper Arbor (Optional)

An arbor is necessary for mounting the drill chuck in the tailstock. It has a No. 2 Morse taper. (C, Fig.28)

Live Center (Optional)

The live center is mounted in ball bearings. It is highly recommended for turning at speeds exceeding 600 RPM. (Fig.29)

ADJUSTMENT

After a period, wear in some of the moving components may need to be adjusted.

Main Spindle Bearings

The main spindle bearings are adjusted at the factory. The bearings may be adjusted if end play becomes evident after considerable use.

Fasten the slotted nut (A, Fig.32) on the back of the spindle, loosen the outer slotted nut (B, Fig.32), and adjust the slotted nut (A, Fig.32) until all end play is taken up. The spindle should still revolve freely. Fasten the slotted nut (A, Fig.32) again and tighten the outer slotted nut (B, Fig.32).

Caution: excessive tightening or preloading will damage the bearings.

Adjustment of Cross Slide

The cross slide is fitted with a gib strip (C, Fig.33) and can be adjusted with screws (D, Fig.33) equipped with lock nuts (E, Fig.33). Loosen the lock nuts and tighten the set screws until the slide moves freely without play. Tighten the lock nuts to retain adjustment.

Adjustment of Top Slide

The top slide is fitted with a gib strip (F, Fig.34) and can be adjusted with screws (G, Fig. 34) fitted with lock nuts. (H, Fig. 34) Loosen the lock nuts and tighten the set screws until slide moves freely without play. Tighten lock nuts to retain adjustment.

Adjustment of Half Nut Guide

The half nuts engagement can be adjusted with screws (1, Fig.35) fitted with lock nuts (J. Fig.35). Loosen the nuts on the right side of the apron and adjust the control screws until both half nuts move freely without play. Tighten the nut.
