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: Some years ago, while I was using a prescription cold medicine, I was hearing drums, bugles, and bagpipes when the refrigerator clicked on or the air conditioner was running.The music stopped when the machinery stopped.There is a technical term for auditory hallucinations which occur in the presence of white noise. Does anybody know the term? I found it in a medical dictionary years ago, so I know that it exists.
- Drums, bugles, and bagpipes? Are you Scottish? Same sort of thing happened to me when I was taking dimetapp.

- I don't have a soul, and never did ... much like your intelligence.
- Q: And if not, what methods do they use to harvest crops?Please state your reference.Thanks
- Gee Levi, I am an organic farmer and I hardly spray my crops at all with pesticides. You do realize that organic pesticides are not persistent in the environment like synthetics that can persist in the soil and water for several years. organic pesticides are generally persistent for a couple of days. Did you know if you have a good balance of beneficial to pest insects you really don't need to spray much at all and you get a marketable crop. I have sprayed zero insecticides this season and so far have sold tons of food to the public. You are also assuming the growing produce is like orcharding-it is not. Apples, peaches etc if grown conventionally get sprayed down with some really nasty chemicals weekly. The organic folks also spray weekly but with things like soap, neem, Bt, lime sulfur, kelp. they also do things like bag each pomme which means almost no insecticide sprays after petal fall. So yes organic growers do use sprays but they are not the toxic sprays conventional growers use-you can eat an organic apple right after organic sprays are applied. Conventional apples cannot be sprayed within 6 weeks of harvest-so you see there is a huge difference in the sprays being used.
- Q: What is a mechanical mouse?
- At present, the mouse on the market is divided into two major categories according to principle: one is mechanical mouse, and the other is photoelectric mouse. And now the wireless mouse.

- Q: Mechanical keyboard?. How much is good?
- SteelSeries 7G was the best, it is good to the keyboard, but this product is worth the price, if the lower 300~400 (original price of around 1000, but in fact most of the more than and 800 machines are better) is recommended; also have to mention the domineering hands support, is comfortable, only 90% people in use after a period of time will get rid of it, because too big and too much in the way of the place

- Q: Which companies provide them with their machinery to build the cars? I'm doing research and need to know these companies.
- First, get a list of every major machine manufacturer outside the United States and Canada and find those which specialize in automation. Then do the same for every machine manufacturer in the United States and Canada starting with multiple operation machines, plastic extrusion and metal presses, forming and turning equipment, conveyor delivery systems and you have a start. The public library may have such listings .
