The Models 250A, and 252 have a capacity of 3/32" to 2" diameter.
The Model 252 is the most versatile drill and tool grinder available today. The 252 can grind odd-numbered fluted tools (1, 3, 5 & 7) as well as even numbered fluted tools (2, 4, 6, 8, & 10). This is achieved with the use of a unique dual-cam workhead. The inner cam rotates at 2:1 gear ratio to grind even numbered fluted tools. The outer cam rotates at a 1:1 ratio for odd-numbered fluted tools.
The Model 252 is available in manual, semi-automatic and automatic in-feed versions.
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: What is mechanical connection?
- Mechanical connection is carried out in mechanical units. Mechanical connections include straight thread connection, taper thread connection and cold extrusion connection of casing pipe.
- Q: Like gears, pulley's and stuff. But not in a technical way, because before I make proper technical designs I need to be able to do rough sketches (don't ask why).

- Sorry, but your question cuts off in mid-sentence and is hence unanswerable. You'll need to add more info in the 'Additional Details' area of your question screen if you desire an answer.
- Q: Other than using a freezer, what are the ways that you can make ice without machinery?
- You can make ice with fertilizer and water. Why it works: Ammonium nitrate (a chemical found in fertilizer)is a salt, which is made up of a 50/50 mixture of ammonium and nitrate nitrogen. When ammonium nitrate is mixed with equal parts water the ammonium nitrate dissolves into the water. The energy is absorbed from the water, which causes the temperature of the water to decrease and therefore freeze, creating ice. Here is what you do: Fill a bucket with equal parts water and ammonium nitrate(fertilizer) place a smaller metal bowl (you can’t use plastic as it is an insulator) half filled with water in the bucket and wait. The bowl of water will freeze and you have clean ice
- Q: A 20kw,200V shunt generator is operated at rated load. if the driving engine is developing 30bhp (break horse power), determine the iron and friction losses.PLease use all the given data above..thanksAnswer is IFL=1039W.Thanks a lot.
- This is the answer I gave to 2 other askers of the same question. brake horse power of an engine is the actual amount of horse power an engine can put out. Using 745.5 watts as a horse power, the engine will supply the equivalent of 30 times 745.7 watts at 30 brake horse power. This is 22,371watts. The generator is supplying 20 Kw or 20,000 watts. The difference in the engine output and the generator output is 22,371 minus 20,000 or 2.371 watts. I don't see how the answer is 1039 watts, if my calculations are correct. Perhaps someone else will have the answer you seek. I may be missing something in your question
