• Semiautomatic device special tool-grinding for corners of undercuts of teeths of the VZ-248 circular saws

Special grinding semiautomatic VZ-248 for angles of undercut teeth of circular saw blades is designed for initial sharpening using the deep grinding of the teeth of the saws are equipped with plates of hard alloy, angles in the radial and lateral undercuts.

The principle of operation of the machine the following: the required angles of undercut on the tooth are obtained by moving the two grinding wheels, the ends of which are deployed on the estimated angle. Moving in circles running parallel to the end surfaces of the disc blades. Sharpening the saw is running in automatic cycle. Completely removing the stock from the saw tooth takes place in one turn grinding wheels. The saw is mounted, is guided and removed at the end of the sharpening manually.

The rotation of the grinding wheel takes place via a belt transmission poly-V belt. Longitudinal feed of the grinding wheels is derived from a hydraulic cylinder with adjustable speed of movement. Moving the prop (division) is derived from a hydraulic cylinder with adjustable speed of movement. Rebound-jump grinding wheels are affected by hydraulic cylinder-rotate relative to the axis of rolling of the caliper. The magnitude of the bounce-jump is governed by stops. Clamp the saw, when rent allowance is a hydraulic cylinder, the sealing clamping stops when the division is performed by a spring with adjustable force tightening, the withdrawal of the clamping stops when grinding is carried out by a hydraulic cylinder.

Key components of the machine located on the frame. To the left of the frame is attached to the pedestal with a fixed bilderatlas and prop. On top of the frame the caliper is installed with two grinding heads. To collect the coolant is attached to the frame pan. Under the pallet mounted tank with pump coolant. To the left of the base there is a hydraulic unit. To protect the machine components and the operator from coolant on the frame is attached to the fence with a niche under the control panel.

Qualitative and trouble-free sharpening in the cycle is provided by the locking devices. Machine configuration allows to obtain the smallest size, to ensure ease of use, maintenance and repair. Semiautomatic VZ-248 is widely used at the enterprises of rail-welding production.
