Abstract
A rotary microtome and a control method therefore are provided. The rotary microtome includes: a specimen holder, configured to hold a specimen; a handwheel drive system, including a handwheel and a handwheel axis, and configured to receive a user operation via the handwheel and to move the specimen holder up and down via the handwheel axis based on the user operation; a damping component, connected to the handwheel axis, and configured to generate damping for rotation of the handwheel axis; a knife; a section motor, connected to the knife and configured to drive the knife to cut the specimen; and a control device, connected to the damping component and the section motor respectively, and configured to obtain an operation parameter of the section motor, and to adjust the damping generated by the damping component according to the operation parameter, such that the user feels a material hardness of the specimen.
