The machine manually self centering chuck in connection with the spindle end consists of short cylindrical and conical chuck short. Short cylindrical chuck generally through the transition plate; short conical chuck can be directly connected with the machine tool spindle end, short conical chuck connection is divided into A1, A2, C, D four kinds of connection form.
A2 type because of the spindle end part of the outer ring threaded connection, so the strength higher than A1, but because the internal structure of chuck limit, except for a small part can be used, most can only use A1 type can be connected with the machine tool spindle end of the inner screw thread lines.C type and machine tool spindle end connected by bolts fastening, which belongs to a quick change chuck, fast loading.
D type and machine tool spindle end connection adopts pull rod, a spindle end cam lock, which belongs to the quick change chuck another.
Short cone chuck chuck taper hole in the gland, and the inside and outside two screws and the chuck body assembled together, to form a closed structure, and therefore high centering precision, good rigidity. Overhanging short. At present, foreign machine tool spindle end and has been widely used in short cone, functional components so short conical chuck machine tool selection is only indispensable, domestic according to international standards, short conical chuck has started to spread. Short cone chuck though a difference of about 25% than the short cylindrical chuck price reduction, but the transition plate cost, the actual price of less than 10%, while the short taper chuck use value is far higher than the short cylindrical chuck. Claw structure short cylindrical and short conical chuck into the overall separation claw and claw two; overall claw claw claw -- basic and top jaws as a whole, and base claw is connected by cylinder head screw six angle, can be adjusted for internal or external jaws.
The separation claw is divided into A type and C type two, A standard, C type refers to special order specifications.
K72 series of four jaw chuck and machine tool spindle end connection consists of short column and short cone two; short conical connection using A2, because A2 and machine tool spindle end outer thread connection strength.
K10 series of two jaw self centering chuck, two claw synchronous mobile is suitable for holding various symmetrical parts, commonly used in the ordinary lathe CNC lathe, grinder, milling machine, drilling machine, and machine tool accessories -- dividing head, rotary table etc.
K11 series self centering chuck, three claw synchronous mobile for clamping shaft, disk type, equilateral triangle and other parts, commonly used in the ordinary lathe CNC lathe, grinder, milling machine, drilling machine, and machine tool accessories -- dividing head, rotary table etc.
K12 series of four jaw self centering chuck, four claw synchronous mobile suitable for clamping square, four square parts, also applies to the shaft, disk type parts, commonly used in the ordinary lathe CNC lathe, grinder, milling machine, drilling machine, and machine tool accessories -- dividing head, rotary table etc.
K72 series of four jaw chuck, a claw can move independently is suitable for clamping eccentric parts and irregular shape parts, commonly used in the ordinary lathe CNC lathe, grinder, milling machine, drilling machine, and machine tool accessories -- dividing head, rotary table etc.
