Reduce machine tool heat to be out of shape what need notices. Below the influence of heat source of inside and outside, each component will produce the machine tool the heat of different level is out of shape, make the opposite motion concern between workpiece and cutting tool breaks ring, also be machine tool quarter drops. To numerical control machine tool, because full treatment process is calculative instruction pilot, hot metabolic effect is more serious. Be out of shape to reduce heat, adopt the following measure normally in structure of numerical control machine tool. 1.

The generation when reducing interior of calorific machine tool to give out heat heats up metabolic main heat source, go out heat source as far as possible from the depart in lead plane. 2.

Control temperature rise, after taking a series of step that reduce heat source, hot metabolic circumstance will be improved somewhat. But the heat source of inside and outside that should eliminate a machine tool completely is very difficult normally, it is impossible even. Must be heated up through coming loose goodly so and refrigeration will control temperature rise, in order to reduce the effect of heat source. Its are mid more effective method is the calorific place in the machine tool cools compulsively, also can adopt heating method in part of machine tool low temperature, the temperature that makes the machine tool is nodded each tends consistent, can reduce the warpage that causes as a result of difference in temperature so. 3.

Improve machine tool orgnaization, below likewise calorific condition, machine tool orgnaization is out of shape to heat also have very big effect. The odd pillar orgnaization that if numerical control machine tool goes,uses is possible be replaced by place of double column orgnaization. Because control semmetry, the main shaft line after be heated of double pillar orgnaization divides the translation that produces perpendicular way outside, of other direction be out of shape very small, and the correction that the axes shift of perpendicular direction can use a coordinate conveniently undertakes compensating. To the main shaft box of numerical control lathe, make the heat of main shaft is out of shape as far as possible on the perpendicular way that produces in cutting tool to be cut. This can make main shaft heat is out of shape the influence to machining a diameter is reduced minimal. Still reduce main shaft center and main shaft as far as possible on the structure the distance to the ground, in order to reduce hot metabolic gross, make the around temperature rise of main shaft box concurrent at the same time, after avoiding main shaft to be out of shape, appear tilt. The ball guide screw in numerical control machine tool often is in predicting load big, rotate speed is high and medicinal powder the job below the condition of hot difference, because this guide screw is easy calorific. The consequence that ball guide screw heats up production to cause is serious, it is especially in open loop system, it can make feed system loses fixed position precision. At present certain machine tool reduces the heat of guide screw to be out of shape with the method that helps beforehand. Be out of shape to adopting afore-mentioned measure to still be heated up indelibly, can try to amend according to measuring a result to give out compensation pulse by numerical control system. 3, reduce motion to chafe and eliminate transmission gap between, workbench of numerical control machine tool (or procrastinate board) displacement measures the equivalent in 11 arteries and veins to be most of subsection, ask again normally can move with the speed of base. To make workbench can right the instruction of numerical control device is made accurate, must take step. Slideway of current and commonly used sliding slideway, scroll and static press slideway to existing in respect of attrition damp character apparent difference. Slip guide screw is replaced to also can get similar result with ball guide screw in feed system. Current, numerical control machine tool uses transmission of ball guide screw without an other place almost. Numerical control machine tool (especially the numerical control machine tool of open loop system) treatment precision depends on greatly the precision of feed drive catenary. Besides the machining error that reduces transmission gear and ball guide screw, another important step is to use unoccupied place transmission of very close to each other deputy. The accumulation to pitch of ball guide screw error, use pulse to compensate device to undertake pitch is compensated normally.
