Cutting machines with high-speed safety systems, and actuators used in high-speed safety systems, are disclosed. The cutting machines may include a detection system adapted to detect a dangerous condition between a cutting tool and a person. A reaction system performs a specified action, such as stopping the cutting tool, upon detection of the dangerous condition. An actuator may be used to trigger the reaction system to perform the specified action.

A surface of a workpiece, from which the burr is removed, is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape (S1). This positional data is corrected by an error caused by a bend of a robot (S2). The thus obtained positional data is compared with the target shape of the surface, from which the burr is removed, obtained from CAD data (S6, S10). A shift of the surface shape in the normal line direction is found (S7, S11). The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position (S8), the shift end position and the shift size (S14). A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed (S16, S17). As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed. Due to the foregoing, it is possible to provide a finishing machine characterized in that useless burr removing actions can be reduced and, further, that the overcutting of a workpiece can be prevented.

The fixation device includes a housing with a housing tool end and a housing template end, a seat located on the housing tool end for coupling with the rotating machine tool, and a clamping mechanism disposed at least partially at the housing template end for coupling with at least one locating pin.

An improved spring tracer for duplicating machine for punched and laser keys comprising a longitudinal spindle suspended from an end of a synchronous lateral lever having the other end laterally connected to a longitudinal shaft for a duplicating tool in parallel with the longitudinal spindle, which can be longitudinally slidably secured on a body portion in accordance with a common longitudinal axis of the longitudinal spindle; a spring-loaded tracer engaged in the inner lower end of the longitudinal spindle for biasing a tracer stylus against an original punched or laser key by means of the spring force for tracing the depths of the key teeth of the original punched key in accordance with the said common longitudinal axis; and a regulating sleeve rotatably secured at the outer lower end of the longitudinal spindle for regulating the elevation of the spring-loaded tracer in accordance with the said common longitudinal axis, in order that a regulating action, a securing action and a biasing action can be effected in a common longitudinal axis, so as to increase the duplicating precision and simplify the construction of the duplicating machine for punched and laser keys.

A decoration-used mold unit for defining a border on a work piece to facilitate cutting or milling. The mold unit includes an elongated rectangular main body formed with a first window for processing a first sink and a second window for processing a second sink. A first chucking section protrudes from a first side of the main body. A second chucking section protrudes from a second side of the main body. At least one abutting member is adjustably arranged at the second chucking section. The first chucking section and the abutting member respectively abut against two opposite sides of the work piece to clamp the work piece. In the processing procedure, the blade is restricted within the first and second windows so that the work piece will not be over-milled and the borders of the sinks keep straight.

A hand-held machine tool comprises a housing 10 with a guide duct for conducting shavings and/or abrasive particles away from an operating region. A collecting container for the shavings and/or abrasive particles is connected to the guide duct, having at least one opening for conducting away air from the collecting container. The opening in the collecting container is at least partially covered by a retaining element made of metal. Preferably the retaining element has a net, gauze, mesh, knit or lattice structure. The tool may be a planing machine.

A pulse generation means that generates a pulse each time an XY movable member moves linearly by a certain amount relative to a base is provided. A workpiece and a light and dark pattern member are provided on the base. A tool, a light and dark pattern scanning sensor that scans the light and dark pattern and outputs a scanning signal, and a cutting means that moves the tool with respect to the workpiece in a cutting depth direction, orthogonal to the linear motion direction, are provided on the XY movable member. While the XY movable member moves relative to the base, the tool is moved by the cutting means in accordance with a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and the pulse from the pulse generation means to perform machining.

In a method for adjusting at least one pressing element of a molding machine for machining workpieces of wood or plastic material relative to a workpiece, transported through the machine and to be machined by the machine, the pressing element is adjusted outside of the molding machine in an adjusting device with the aid of a template of the workpiece and the adjusted pressing element is then inserted into the molding machine.

A method for plunge milling a workpiece. The method includes rotating a cutting head while advancing the cutting head along a direction towards the workpiece; removing material from the workpiece with frontal teeth disposed on a frontal face of the cutting head; bending a tool holder configured to lead the cutting head inside the workpiece; stopping the advancing of the cutting head along the direction towards the workpiece when the cutting head has reached a predetermined depth inside the workpiece; and retrieving while rotating the cutting head from the inside of the workpiece such that side teeth of the cutting head remove material from the inside of the workpiece due to the bending of the tool holder.

A table with a working surface has a parallel rail on each side of the working surface. A slide assembly includes a shaft with ends and a pair of brackets. Each bracket has a hole. The holes receive the ends of the shaft. The slide assembly includes cylindrical tunnels. The tunnels slidably receive the rails. An operating assembly has primary and secondary arms. Each arm has a free exterior end and an interior portion. The interior portion is coupled to the shaft. A router is secured to, and depends from, the free end of the secondary arm. Control mechanisms include a scribe. The scribe is secured to, and depends from, the free end of the primary arm. Movement of the primary arm and scribe with respect to a template will cause corresponding movement of the secondary arm and router with respect to work pieces to be routed.
