A dairy has carried out prototyping tests for a turning application of more than 40 m with stringent environmental conditions.

Control and regulating means are provided for controlling the speed of primary and secondary traversing of the roving condenser.

On each axis of a machine tool, the tracer head is driven independently of the tool by sub-motors additively provided on the feed shafts for the tool.

Stock removal shapes the sword from prepared stock that is larger in all dimensions than the finished sword by filing, grinding and cutting.

This torque control by the feeding shaft allows the cutting reaction force generated between the drill (75) and the work (91) to change so as to follow up the predetermined pattern.

The blade edges of the multiple tools (120) line up evenly along the second feed shaft (B) when the multiple tools (120) are inclined as a unit.

A ruler (124) is located on carriage means (11) and has an unobstructed drafting edge (125) constantly co-linear with a true radial line to a chosen vanishing point.

The pride and joy of the workshop is a 8mm Lorch, “left handed” (they seem to be easier to find, it does not change anything much except the cross-slide operation), with two ball bearings on the headstock.

A drafting device (10) is provided for drawing parallel lines as well as true perspective lines, comprising carriage means (11), movable over a drafting surface (12) on wheel assembly means (20) and (21).

The feed rod device is provided with an actuator (M), which variably applies a rotational torque on the fixed section of the first speed reducer (60) and/or the fixed section of the second speed reducer (80).

A cutting reaction force estimating means (1) estimates a disturbance torque Yz acting on a servomotor (63) based on a speed signal x1z of the servomotor (feeding shaft) (63) and a torque command value U1z to the servomotor (63).
