The semiautomatic machine is manufactured according to the performance specification approved by the Buyer. The semiautomatic machine is designed for grinding of external helical surfaces of the work pieces by single-rib grinding wheel with coolant-cutting fluid. Abrasive aluminum oxide wheels which can be profiled directly on the semiautomatic machine are used as grinding wheels.

The semiautomatic machine is made in the horisontal format. The base is the foundation, on which main assembly units of the semiautomatic machine are mounted. In the front part of the base there is a table movable in the longitudinal direction (X-axis), on which workpiece headstock (А-axis) with blank to be machined, tailstock and dressing mechanism for grinding wheel are mounted. In the back part of the base there is a cross carriage (Z-axis), on which swing reducer for wheelhead is mounted (C-axis). Working area is fully covered by a cabinet-type guard, with sliding and assembled doors.

*Specified at a stage of coordination of the specification

The warranty period of operation of a semiautomatic device makes 12 months from the date of its commisioning according to the Act on input of a semiautomatic device in commercial operation, but no later than three months of the delivery date and on condition of carrying out balancing and commissioning by experts of the Seller. Guarantee certificates extend to production acquired directly from the Seller or through official commercial agents and dealers of the Seller.

The seller renders additional services in carrying out balancing and commissioning, development of the steering programs for processing of other types of products. Guarantee certificates extend to all types of the additional services rendered by the Seller, his official commercial agents and dealers. Conditions of providing the above-stated services make a reservation the separate contract.
