Refer to the operator's instructions before attempting to lift any lathe.
Three common lathe dogs are illustrated in Figure 7-25.
The drill chuck, Figure 7-19, is a convert pdf to word indowebster small universal chuck which can be used in either the headstock spindle or the tailstock for holding straight-shank drills, reamers, taps, or small diameter workpieces.Check the accuracy of the faceplate surface using a dial indicator, and true the-faceplate surface by taking a light cut if necessary.Keep all safety equipment, along with necessary cleaning marking, and lubricating equipment, in the immediate lathe area to use as needed.If this happens, the work must be removed from the chuck and the point extracted.Instalación y enlaces a las descargas.Before grinding, shaping, desert storm 1 full game or sharpening a high-speed steel tool bit, inspect the entire grinder for a safe setup and adjust the tool rests and guards as needed for tool bit grinding (Figure 7-12).Descriptions for the other lathe attachments follows.Each grinder is usually equipped with a coarse-grained wheel for rough grinding and a fine-grained wheel for fine and finish grinding.This provides the most secure and accurate base for the cutting tool and helps eliminate unwanted vibration during facing operations.Some common lathe attachments are the steady rest with cathead, the follower rest, the tool post grinding machine, the lathe micrometer stop, the lathe milling fixture, the lathe coolant attachment, the lathe indexing fixture, and the attachment (or Versa-Mil).Rotate the spindle 180, engage the spanner wrench, and give four or five solid hammer blows to the spanner wrench handle.
Which work holding device to use will depend on the size of the work and the particular operation that needs to be performed.
Public affairs officer Pierre Leblanc said the armys priority in the Laval area would be filling and stacking sandbags and protecting critical infrastructure near the river, which he said was rising about one centimetre each hour.
Tungsten carbide, tantalum carbide, titanium carbide, ceramic, oxide, and diamond-tipped tool bits (Figure 7-8).
The roughing cut should be as heavy as the machine and tool bit can withstand.At this angle of the compound rest, the movement of the cutting tool will always be half of the reading of the graduated collar.Mount the workpiece and tighten the jaws loosely onto the workpiece (Figure 7-35).Set the lathe carriage stop or micrometer carriage stop at this point to reference for the end of the cut and to protect the lathe components from damage.Shoulder turning in this manner can be accomplished with a few roughing cuts and a finishing cut.Urgence Quebec said that as of Sunday afternoon, 1,280 residences across the province had been flooded and more than 1,500 people had left their ve major floods were identified as threatening thousands of Quebecers, and so far one death has been blamed on the high.In order to effectively grind a tool bit, the grinding wheel must have a true and clean face and be of the appropriate material for the cutting tool to be ground.The tool post should be set on the left-hand side of the compound rest T-slot, with a minimum of tool bit and tool holder overhang.A soluble oil and water mix has lubricating qualities dependent upon the strength of the solution.The headstock is located on the operator's left end of the lathe bed.Facing Work Between Centers Sometimes the workpiece will not fit into a chuck or collet, so facing must be done between centers.Using the micrometer stop can sometimes be faster and easier than using the compound rest graduated collar for measuring tool bit movement.The side and end relief angles are generally somewhat less than for turning tools.Standard tool holders for high-speed steel cutting tools have a square slot made to fit a standard size tool bit shank.
Do not use faceplates on different lathes, since this will cause excessive wear of the faceplate due to repeated truing cuts having to be taken.
