Abstract:
The present invention relates to a"waste profile sliding-part" (1) which allows the waste profiles (3) to separate easily from the saw (2) during cutting of PVC and aluminum profiles (3). Thanks to the waste profile sliding part (1), the waste profiles (3) are easily separated from the saw (2).
Abstract:
A portable table saw (100) in one embodiment includes a base (102), a first support post (120) and a second support post (122), each of the first and second support post extending upwardly to a location higher than the base (102), at least one support rail (124, 126) having a first end portion supported by the first support post (120) and a second end portion supported by the second support post (122), a saw (108) movably mounted to the at least one support rail (124, 126) at a location between the first end portion and the second end portion, the saw (108) positioned above the base (102) and movable along the at least one support rail (124, 126), and a first pivot mechanism (128) configured to pivot the saw (108) with respect to the base (102).
Abstract:
A cutting device comprises a pivotable cutter drive support section (100), which comprises a cutter drive unit (102), a right hand cutter disc (104) and a left hand cutter disc (106). The support unit (100) also includes a cutter feed drive motor which drives a support bracket (110) backwards and forwards to move the cutter discs (104 and 106) in the direction of their plane of rotation towards a pipe to be cut. The pivotable adjustment of the support unit (100) allows for different angles of cutting for production of a chamfered edge of a pipe (22). The cutting angle may be varied up to 35 DEG either side of a vertical centre line.
Abstract:
A table type, mitre box cross-cut saw has a stationary frame (2) at the top of which a table top (3) may be swivelled around a horizontal axis (16) and locked in its horizontal positions. The table top (3) carries a saw unit (7) with an electric motor and a circular saw blade (11) driven by the electric motor. The saw unit (7) may be swivelled, tilted and locked with respect to the table top (3) around a multiaxis hinge (6). A turntable (8) is embedded in the table top (3). A saw opening (28) arranged next to the turntable (8) allows the saw to drive to a maximum extent in any selected mitre cut adjustment, precluding all collisions between the table top (3) and the saw blade (11). The cross-cut area is thus independent from the setting of the mitre cutting angle.
Abstract:
A machine tool for machining elongated elements (50), in particular profiled elements of frames, comprises a cutting unit (2) for rotatably supporting a disc blade (21), supporting means (3, 4, 5) of an element (50) to be machined, driving means (25, 26, 27, 34, 44, 54) for moving said cutting unit (2) and/or said supporting means (3, 4, 5) so as to cause an interaction between said element (50) and said disc blade (21); the supporting means (3, 4, 5) is such as to enable said element (50) to perform a rotation around a rotation axis (A) coinciding with, or parallel to, a longitudinal axis of said element (50).
Abstract:
Bei einer Vorrichtung zum Führen handhaltbarer Sägen (200), mit zwei im Abstand angeordneten, zueinander parallelen Führungsschienen (110, 120) für reziprozierbar geführte Bewegungen einer Säge, wird eine stufenlose Höhenverstellbarkeit dadurch erreicht, dass die Führungsschienen mit zwei im Abstand angeordneten, zueinander parallelen Konsolenelementen (130, 140) verbunden sind derart, dass die Führungsschienen im Bereich ihrer jeweiligen Enden an jeweils ein Konsolenelement angrenzen, wobei die Konsolenelemente jeweils Befestigungseinrichtungen (131, 132; 141, 142) zum höhenadaptierbaren Befestigen der Konsolenelemente an zwei sich gegenüberliegenden Kanten eines Werktisches (400) aufweisen.
Abstract:
According to the invention there is provided a sawmill, the sawmill having first and second support frame 1 and 2, first and second rails 4 and 4, a first carriage 5, a second carriage 6, height adjustment drive means, and connection means; the sawmill being formed such that when it is in use it can be arranged with the first and second support frames 1 and 2 holding the first and second rails 3 and 4 in substantially horizontal elevated parallel relationship, the first carriage 5 being associated with the rails 3 and 4 and being capable of carrying a saw 7 longitudinally along such rails, the second carriage 6 being capable of moving the saw cross-ways with respect to the rails, the drive means being associated with the first support frame and the connection means connecting the drive means with the first rail and the second end frame; the sawmill being formed such that when it is in use the drive means can move the connection means to impart a lifting force at each of two opposite end parts of the first rail 1 to cause the first rail to raise while the first rail maintains a substantially horizontal orientation.
Abstract:
An improved chuck which retains the shank (100) of a cutting element (101) securely therein and may be manufactured from a single piece of metal provided with a throughbore (114) which is threaded at one end (120) to mate with a driving unit. The other end of the throughbore (114) may be sized to receive a cutting tool shank (100) or a collet (115) with a longitudinal slot (107) extending completely through the collet (115) making it resiliently insertable within the throughbore (114). A clamping means is positioned offset from the centerline of the tool shank (100) or collet (115). The clamping means may comprise two sleeves (108, 109) machined to mate with the peripheral surface (140) of the collet (115) or with tool shank (100). The sleeves (108, 109) are retained in a bore (116) extending transversely through and displaced from the center of the chuck. A threaded element (110) draws the sleeves (108, 109) into contact with the collet (115) or tool shank (100), maintaining a precisely centered cutting tool (101) orientation.
Abstract:
A power tool includes a support arrangement and a work surface that is supported by the support arrangement and that includes a top surface having an opening configured to receive a rotatable blade. The power tool also includes a cutting assembly that is supported by the support arrangement and that includes a motor, a drive shaft driven by the motor, and the rotatable blade rotated by the drive shaft. The power tool also includes a height adjustment mechanism coupled to the support arrangement and to the cutting assembly. The height adjustment mechanism is configured to move the cutting assembly upwardly and downwardly relative to the top surface. The height adjustment mechanism includes a threaded shaft, at least one nut threadably coupled to the threaded shaft, and at least one connection member rotatably coupled to the at least one nut and to the cutting assembly.
Abstract:
A wheeled trolley carries various tools across an object to be worked. A track attaches directly to the work and simultaneously isolates the tool from the work. A standard connection to the trolley readily accommodates a variety of diverse tools, using a keyway or the like to ensure accurate and repeatable placement of the tools. A preferred contouring guide allows a tool to be moved through an arc, where the focal point of the arc may be set to produce an infinite variety of custom shapes, bevels or angles of cut. An upper stop is provided which readily sets the break line between surface finish and edge contour. An adjustable tool carriage allows control over both position and force, including preloading a work tool with force. Resilience is incorporated into the apparatus to accommodate diverse hardness and abrasion characteristics, and, in at least one embodiment, to enable the track to accurately follow a warped or sagging work piece. Additional supports permit the following of a non-linear edge, and the polishing of arcs and circular objects.
