The Gibraltar Catapult Linear Motion Bass Drum Pedal was designed to provide a true response from the players' foot to the surface of the bass drum head by utilizing natural motion from the ankle. Upon consulting with a reputable fitness research agency, Gibraltar designed the Catapult pedal to allow the natural function of the extensor and flexor muscles. Conventional bass drum pedal designs utilize frames with cam drives attached to springs. While pressing down on the pedal board, these springs produce a resistance promoting speed and power. In extended playing situations, this resistance often causes fatigue to the muscles of the lower leg and foot resulting in hindered playing and technique. Careful observation of the muscle groups used with a conventional-style pedal showed that the return stroke or upward movement of the foot was accentuated by the return spring. This caused major resistance, hindering the natural motion of the ankle.

Plastic Mold Parts Grinding Technology

A Plastic mold surface grinding of the technical requirements

1.1 Plastic mold surface grinding of technical indicators

Precision machining and Plastic mold machining precision represents the different stages of development, usually classified by machining accuracy can be divided into general machining, precision machining, ultra precision machining three stages.

As the continuous development of production technology, divided over the limits will gradually move forward, past the precision machining of us, today is ordinary processing, therefore, the limits of their division is relative, and there has been no specific numerical constant.

Precision machining is the machining accuracy of 1-1μm, the surface roughness Ra0.1-0.025μm process technology; Plastic mold machining is the machining accuracy is higher than 0.1μm, surface roughness is less than 0.025μm Ra processing technology, , Plastic mold machining is also known as sub-micron processing. However, the Plastic mold machining has entered the nano-precision stage, the emergence of nanofabrication and its corresponding technologies.

According to the present basis for precision grinding, combined with Plastic mold surface grinding of foreign technical indicators, the following Plastic mold surface grinding machine of technical indicators and technical indicators that have been achieved and compared.

1.2 Plastic mold surface grinding of the technical requirements

Plastic mold surface grinding of technical indicators, we can offer Plastic mold surface grinding machine technical requirements: vertical feed grinding machine to realize micro-feed, the machine has sufficient static and dynamic rigidity, in particular, is the machine's thermal deformation and vibration control than the conventional machine tools should be qualitative improvement.

2 Plastic mold surface grinding method and means

As noted above, in order to achieve these technical requirements to achieve the desired specifications, the machine's design and specific structure of machine tools, machine tool requirements and the traditional greater improvement and enhancement, based on our experience and precision machining of foreign technical data collection and analysis, combined with surface grinding machine tool structure, movement requirements, can be machine main unit is divided into the following techniques: (1) machine layout type; (2) the use of new materials; (3) precision rotary spindle technology ; (4) micro-feed technology; (5) sports guide type; (6) high-precision temperature control technology.

2.1 Machine layout pattern

Machine layout type is extremely important, is the key to success and failure, but the Plastic mold grinding technology is the development of precision grinding come from abroad has achieved Plastic mold surface grinding machine to see its structure type variety, both "grinding first mobile "and also" mobile columns "or" Cross mobile extension units ", without exception, none of the layout structure from the traditional type of machine. From what we know based on high-precision grinding technology that uses the machine structure, "Cross mobile extension units" suitable for Plastic mold surface grinding machine tool. Because the structure type, structure and layout of symmetry with a good machine, good thermal stability; main low center of gravity moving parts, smooth movement and so on.

2.2 The use of new materials

Plastic mold Grinding of thermal deformation of machine vibration control and demanding. Pieces of material in the machine tool application infrastructure, we should break through the conventional gray cast iron-based principles, with some new material, such as: non-metallic materials - resin concrete, the vibration damping materials, heat gradient, linear expansion coefficient and other features are much better than metal. This is used in foreign countries were mature, in the country have used examples such as the Shanghai Machine Tool Works Co., Ltd. CNC camshaft grinding bed artificial marble material used to obtain good results. Therefore Plastic mold surface grinding machine based on the key parts, such as bed, column, extension units and other materials should be man-made marble.

2.3 Precision rotary spindle technology

Spindle is Plastic mold surface grinding one of the key technologies, their value requires the following 0.1μm, and its stiffness, thermal expansion, vibration and other aspects should have a very good performance.

Static pressure air bearing spindle assembly has the following advantages: high rigidity, friction Elementary School, a small temperature change, can work under high speed, high precision turning, its precision can reach 0.1μm-0.025μm, radial and axial stiffness 100-300μm between the wear rate is small (close to zero), long life, require little maintenance. Aerostatic bearing spindle which will be the first choice for Plastic mold surface grinding.

2.4 micro-feed technology

In the Plastic mold surface grinding, grinding wheel of micro feed is being processed parts dimensional accuracy and surface quality of an important guarantee. Currently, precision surface grinding process, its progress to the commonly used "servo motor and ball screw," the typical purely mechanical way, generally can achieve 0.1μm trace feed for the limit. To achieve the required Plastic mold surface grinding 0.1μm-0.01μm and even a smaller micro-feed, the traditional mechanical approach has been not apply.

Information from abroad about the current implementation of trace feed mainly in two ways: First, the displacement of piezoelectric ceramics, high resolution, fast response characteristics, the second is the use of the thermal deformation theory realization of micro feed. One piezoelectric ceramic micro-feeding mechanism in use in more common, has been a steady feed to 0.01μm trace, which, in the preferred Plastic mold surface grinding process is used in this way. Secondly, the Plastic mold surface grinding the initial stage of development, if we use the traditional mechanical approach to refinement, stability and achieve 0.1μm trace feed and to meet the most Plastic mold surface grinding needs.

Sports Guide Type 2.5

Plastic mold grinding wheel and workpiece is to rely on relative motion to achieve, it not only has a precision rotary grinding wheel movement, but also the parts with Plastic mold linear motion, its accuracy should be within the 0.1μ/100mm. Which often use static general guide, use the running high precision, non-crawling and so on. Static pressure guide is divided into two kinds of hydrostatic and aerostatic. In general, hydrostatic guideway stiffness, function in a grinding machine is widely used, but its structure is relatively complex, due to oil viscosity shear resistance, the more serious heat, heat distortion control is relatively difficult. Thus, with more applied aerostatic guide.

2.6 Precision Temperature Control

On Plastic mold grinding, the thermal deformation of machine tool control is extremely important, and this machine in the machine layout design process, we must consider thermal symmetry and thermal stability and can be considered to be preliminary design of advanced control.

Machine tool movement on the heat generated by the grinding heat, must be strictly controlled by thermostat means, such as oil, used rail bearings air, coolant, etc., the temperature control precision should be less than 0.1 oC. Environmental temperature also affect the Plastic mold surface grinding a major factor, consider using multi-temperature controls, machine tool environment surrounding the temperature controlled at 20oC ± 1oC, the near ambient temperature should be controlled at around 20oC ± 0.1oC, but also control of human (operator) on the temperature.
