Rush drill and tool drinders, models 382s

Product Description:

The Model 382S offers a unique combination of versatility and capacity. It has a dual-cam workhead for grinding both odd (1, 3, 5 & 7) and even (2, 4, 6, 8 & 10) numbered flutes and the large capacity of the Model 380. The Model 380 workhead has only even-fluted capability.

The Model 382S is available in semi-automatic and automatic infeed versions.

Selected Optional Accessories

Semi-Automatic Version (Standard for Model 382S)

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 also 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.
