We had a Wasino LJ63M mill turn for several years and used KM50 and Komet ABS drills to reduce setup time. Capto tooling systems Mechineer (Mechanical) Even though quick change tooling can save some in setup time, the lack of rigidity can increase machining times, scrap, and tool wear to the point of costing more than changing stick tools. With that said, we use Komet ABS drills, some KM tooling and would consider Capto for some jobs. The KM50 was the least stiff and had the greatest non linear deflection. The Capto 50 did not have any low load problems but the deflection became greater as the load increased in a non linear way. of tool pressure in the X direction.Įach of the quick change tools had problems, the ABS 50 was the next most linear in deflection after an initial preload was applied, we saw ±.0005” movement with less than 50 lbs load applied initially. The most rigid tool was the 1 ½” boring bar, its deflection was linear, for each 10 lbs of load applied the deflection measurement was the same. 0001” indicator was mounted on the turret disk near the tool block and located a specific distance from the load cell point to measure deflection at given loads.
The load cell was located the same distance from the joint face on the quick change tools, and from the sleeve on the stick tool. A 2 ½” diameter part was chucked with 4” of stick out, a load cell was connected to the chucked part and the boring bars. The test was done in a new Hitachi HT40G turning center.
Tested were new KM 50, Capto 50, ABS 50 boring bars and clamping units, and a 1 ½” steel shank boring bar. * If you have any questions or special requirements for other lengths and tapers, please contact us and we will help you out! *īT50 - M24 X 3.0 Most common spindle testbar is a CAT40 or CAT50 runout test bar arbor.Ĭall for current availability - we generally have in-stock CAT, BT Test Bars, others are generally a 1-2 days before we can ship.Back in 1996 we did stiffness tests with quick change tool joints compared to a 1 ½” boring bar. If we do not have specific testbar tool holder listed give us a call to quote.Ĭlick Below Links in The TestBar Table Below To Purchase Item - Spindle Runout Gauge
Spindle Test Bars are available for all major machine tapers including:ĥ0 taper test bar, 40 taper test bar, 60 taper test bar tools used to check all your spindles machines are available. These are surface hardened and not a soft material like many of the cheaper test bars available on the market. Capto - Maximum runout error 0.005mm / 5 micron / 0.0002 inch.ĭoes not include retention knobs (use one from your machine as they are different for machines).KM - Maximum runout error 0.005mm / 5 micron / 0.0002 inch.HSK - Maximum runout error 0.003mm / 3 micron / 0.0001 inch.CAT/BT/ISO/DIN - Maximum runout error 0.003mm / 3 micron / 0.0001 inch.Spindle testbar runout tolerances and accuracy Check them after a machine has been crashed and take the proper steps before you start making scrap parts. Spindle Runout Testbars are easy to use and a fast way to verify your machine spindle is running properly. The spindle runout test bar can be used to test your CNC machine tools for accuracy and alignments, and also to ensure a stable production environment as well as consistency moving jobs from one machine to another. High tolerance testbars are Important which is why we sell them.The largest cause of excessive tool wear and tool breakage are directly caused from machine tool spindle runout as well as excessive slop or axial play. Many of the cheaper testbars on the web have much lower tolerances=less cost
