6 Piece quick change tool post set 251-100 cnc lathe machine tool post from China
The 251-100 Piston Style Tool Post Set is a fast tool changing system designed specifically for regular lathes, featuring a piston locking structure that significantly improves clamping efficiency and machining accuracy.
Component Description:
(2-1/2" Length x 2-1/2” Widthx 3-7/8”Height) Piston-style tool post -250-100
250-101 Turning & Facing Holder with 3/16-1/2” Tool Capacity
250-102 Boring, Turning & Facing Tool Holder with 3/16-1/2" Tool Capacity
250-104 Boring Bar Tool Holder with 5/8 & 3/4" capacity
250-107 Universal Parting Blade Tool Holder with 1/2" blade height
250-110 Knurling, Facing & Turning Tool Holder 3/16-1/2"
Piston style locking mechanism
Internally, it adopts a spring preloading+hydraulic/pneumatic piston locking structure. When the turret seat is inserted into the spindle hole, the internal piston automatically pops out and locks in the positioning groove, achieving quick fixation. When releasing, simply press the release button or lever to remove the turret.
Quick Change - High repeatability positioning accuracy
modular design
Contains a main tool post body and multiple replaceable tool holders modules.
Support installation of various cutting tools: external turning tools, groove cutters, thread cutters, cutting cutters, etc. (usually square cutter bars).
Strong compatibility
Can adapt to the square tool table holes of most standard lathes.
Summary of advantages:
High precision repeated positioning with small errors and good processing consistency;
Easy to operate without the need for a wrench, tool change can be completed with one hand;
Stable structure with strong locking force, good seismic resistance, suitable for heavy cutting;
Notes:
Clean the interface before use and regularly add lubricating grease to prevent sticking.
Not recommended for high-speed precision CNC lathes.
Ensure that the base is tightly attached to the middle drag plate during installation to avoid looseness.
