Global Partnerships In 1989, Logansport Machine Company joined forces with Japan s Matsumoto Machine Company (Kanazawa, Japan), a world-class partner and international leader in power chucks, rotary tables and other workholding devices. In 1992, LMC associated with Neidlein Spannzeuge Gmbh (Stuttgart, Germany) to provide face drivers and live and dead centers worldwide. Most recently, LMC has partnered with Atlings Maskinfabrik AB (Ockelbo, Sweden), a leader in steady rests.

3 Chuck Selector Guide Standard Chuck For More Secure Gripping PB Pin Arbor Chucks PB type chucks pull the jaws back to more securely clamp the work. Pulling action of jaw clamps provide secure, yet not excessive workholding force Dust seal for maintenance free operation 5, 6 8 and 10 sizes available For More Turning Speed and More Secure Clamping Accuracy PBH Pin Arbor Chucks Similar to the PB in pull down clamping action, PBH type chucks also provide O.D. slide guides to enhance increased turning speed, accuracy. Pulling action of jaw clamps provide secure, yet not excessive workholding force O.D. slide guide delivers more accurate clamping high speed turning capabilities 5, 6 8, 10, 12, and 15 sizes available For Angled Work Parts Requiring Accurate Clamping and More Gripping Force PG & PS Power Swing Chucks Jaws swing to clamp work, suited for nearly round forged or cast parts. Pulls the work piece when clamped Securely clamps work with draft angle by swing clamp action (best sealing, ensures accuracy, steadiness over long machining periods) 6, 8, 10, 12, 15 and 21 sizes available (For ID gripping of ring shaped parts, choose our PBN Pin Arbor Chucks.)

4 PS/ PSC & PG/PGC Power Swing Chucks Our PS and PG Chucks are suited for round/nearly round parts (specifically forged or cast parts) that require machining. They use a ball lock, knuckle mechanism that functions as a pull-down and clamping device, improving clamp accuracy and steadiness over long machining periods. Both models are offered standard in 6, 8, 10, 12 15, 18 and 21 sizes. The PS Chuck is typically used for centering work not requiring a thru-hole. The PG Chuck can be supplied with air (for sensors) or coolant through the chuck.

Because the jaws float independently, it is suited for rough castings that are not perfectly round and are more difficult to clamp with self-centering chucks. The PSC and PGC chucks are designed with chuck jaws that compensate to make sure that grip force equals out on all jaws. Both compensating models are available with air, coolant or both air and coolant through the chuck.

6 PB Pin Arbor Chucks LMC offers multiple models and sizes of Pin Arbor Chucks. Our PB Chuck is suited to holding round workpieces with flat surfaces (IE: machining brake disc rotors). When flat faced, large diameter parts need to be faced or bored out, often the application calls for the force on the radial surface to be minimized. Because the PB Chuck offers a pull-down feature and radial clamping feature, excessive clamping force and distortion is nearly eliminated. The PB Chuck is offered standard in 5, 6, 8, and 10 sizes. It can be supplied with air, coolant through the chuck, or both air and coolant.

7 PBH Pin Arbor Chucks Like our PB Chuck, our PBH Chuck holds round workpieces with flat surfaces. The PBH Chuck additionally features a standoff behind the chuck to support the back side of the jaws. The result it gives the chuck added rigidity and greater support so longer parts will not flex during machining, especially important in higher speed machining. The PBH Chuck is offered standard in 5, 6, 8, and 10 sizes. It can be supplied with air, coolant through the chuck, or both air and coolant.

9 2R Cylinder Just one of several different models and sizes of hydraulicallypowered rotating cylinders, our System 2R Hydraulic Rotating Cylinder is well suited to handle a wide range of your high performance chucking applications. They are compact (for increased operation in restricted areas, ideal in vertical applications where spindle-to-floor dimensions are critical) and lightweight to help high speed operation. Stroke detection via proximity switches ensures the chuck s opening/closing. 2R Cylinder Dimensions 2R 105/ R 120/ R 120/21-35 RNKP150/35-01 Max Speed (min-1) Max Pressure (Kgf/cm 2 ) Piston Dia (mm) Piston Stroke (mm) Piston Area-Push (cm 2 ) Piston Area-Pull (cm 2 ) Weight(kg) GD 2 (Kg-m 2 ) A, mm B, mm C, mm D, mm E, mm F M28P1.5 M28P1.5 M28P1.5 M24P3.0 MALE G (max/min) 32/7 37/12 42/7 105/70 H, mm L, mm M, mm N, mm P 6-M8 x 75 6-M10 x 75 6-M10 x 85 6-M12 S, mm U, mm W, mm X, mm PT PT1/4 PT1/2 PT1/2 PT 1/4
