The Models 250A, and 252 have a capacity of 3/32" to 2" diameter.
The Model 250A has a 2:1 ratio only. All models use hardened cams and the cam change takes only 5 seconds. When no cam is in place, the workhead can be used to spin grind or index grind (12 positions). The Model 250A incorporates a wide capacity and versatility in an affordable package. The innovative design of the Model 250A allows for the grinding of almost any drill geometry, and most are completed in a single chucking. The versatility also extends to taps, reamers, countersinks and end mills. Many of these tools can be ground with very little change in set-up. The Model 250A is available in manual, semi-automatic and automatic in-feed version.
Additionally, the Model 250A is available as a structural steel version specially equipped for easily putting the structural steel point on drills.
Selected Optional Accessories
Semi-Automatic Version
The power-driven workhead of the semi-automatic version offers a quiet, smooth rotation of the workhead. Manual effort is reduced for heavier grinding and spin grinding operations. Spark out is allowed to occur by using a minimum of manual infeed along with a reduction in workhead rotation speed. The speed is controlled by a conveniently located valve; the adjacent four-way valve allows grinding in either direction. A hand knob on the workhead is used for indexing and setup.
Automatic Infeed System
The semi-automatic versions can be equipped with the automatic infeed system. This can increase productivity by allowing the operator to do other nearby tasks while the drill is being ground. The system allows manual or semi-automatic grinding of all tool grinding, and use of the automatic infeed for standard drill points, countersinks and reamers. The grinding rate is adjustable and the counter can be preset for 1-99 cycles. An electroplated CBN wheel (standard) is used with the automatic infeed and requires no dressing. Larger, three-phase motors are standard and an ammeter is provided to monitor the grinding load.
Overhead Wheel Dresser
Timesaving option allows truing of the grinding wheel O.D. without changing the setup. (Not for use with diamond or CBN wheels)
Features:
Sealed linear bearing with hardened guide shafts
Downfeed with ball detent in .001" increments
Hardened downfeed screw with wiper seal
High-quality diamond included for truing standard and ceramic wheels
Air Bearing Fixture
Air Bearing Fixture on Model 250A Drill and Tool Grinder
Allows precision sharpening of endmills, reamers, shell mills and other cutters. The spindle is supported with a thin film of air providing nearly frictionless motion, resulting in a smooth, even grind. The fixture quickly mounts on the Model 132C, 250A, 252, 380 or 382S grinders, or is available with a universal base to fit most tool and cutter or surface grinders.
- Q:I wanted to be a petroleum engineer due to its high salary, but am unsure if it's worth it.Is it worth it? Is it fun?Aeronautical engineering doesn't have a salary as high, but it seems like a fun job.I am hard of hearing and wear hearing aids. I suppose both jobs would accept this type of person.Which of those jobs has a better hiring rate?
- Petroleum engineers do not have any thing to do with the design of machinery. Their primary interest is the underground reservoirs that contain oil and gas. They can spend some time around a drilling rig but they do most of their work in an office. Having hearing aids should not be a problem in terms of employment. You need to realize that picking discipline for salary is the wrong thing to do for two reasons. One you should always work at something you enjoy and are good at. Two, just because a given discipline has a higher average salary doesn't mean you will be one of the engineers that earns that higher salary.

Currently, we make these from aluminium extrusion and steel infill panels. I'm looking to redesign.Does anyone have suggestions for alternative component systems which provide reasonably strong structures, while being assembled without welding and do not require painting? I've looked at aluminium composite panels and GRP.ThanksS

- Q:i need the jetty construction machinery for jetty construction on the island?
- A jetty normally has a piled foundation, so assuming that you have a suitable seabed. Some form of piledriver or water / air jetting device to install the piles. This will depend on their loading requirements. A crane to assist with the decking. For a simple jetty you may be able to use manpower. Some more information about the size of the jetty and its future use would be useful for a more complete answer
